What does BPU (TM) stands for? (BPU (TM) is a trademark of SupraStore.com)
Base power. These changes are: a total length of three inches down the tube (with or without-out high flow cats), 3 "(75mm) or bigger cat exhaust system, raised boost (18psi), and cut off 'eliminator boost it needed (GReddy BCC) needed to reach the lift without activating the factory fuel cut-off at 14-15psi. These are the changes that need to be the best deal for HP-to-$ $ $Ratio.

What does it mean when someone says BPU + (TM) +? And what is APU?
This stands for any additional power producing modifications other than the basic BPU (TM) changes. A "+" refers to Adj Cam Gears and pulleys, the second "+" refers to a fuel controller, ECU upgrade, etc. For example, one with the Supra (TM) change the BPU, and a front-mount intercooler, would be called BPU (TM) +. If you added cam gears that would be the BPU (TM) + +, and so on. L '"BPU (TM)" concept will be used until you have upgraded Turbo (s) have. Then he called APU, advanced performance upgrades. This designation covers virtually any changes that may take place.
What are the first changes to the engine have to run?
I recommend starting with the promotion of the collection at about 18psi stock turbo. This requires a quality indicator and push a boost cut eliminator (GReddy BCC). They are treated with 15 or so PSI with the stock to reach down the pipe in place.This is another example of 30rwhp. After these changes have been completed, would be a logical next step to install the rain and the cat-back exhaust system from both. Now it will be at full BPU (TM).
What do the various "Free Mods" do?
There are many different "free mods" for the Supra TT. I'll just cover some of them here. Those who fall into three categories, cover charge pressure control, EGR disabling, and TTC or True double conversion.
Three of thethe boost control mods are: Bleeder-T Mod, Mod terminal and the VSV Bypass Mod Each of these changes increase the levels of thrust, without using a boost controller. But we must keep a watchful eye on your boost gauge and make sure not to increase the turbo too high (18psi is a safe level).
The next mods are mods true twin conversion (or TTC). This change disables Sequential Twin Turbo and causes the turbo to always run in parallel (both atat the same time). This will allow some 'best mid-range (before the secondary turbo normally come online) and provides a smoother power band, without the sharp increase in growth caused by the transition from primary to secondary operation. This, however, significantly reduce the supply of low-end and increases exhaust noise levels, and therefore may not be desirable for the road. Two types of TTC mod which includes the traditional TTC mod 2 methods, wiringactuators, or installing a directional valve, and electronic TTC mod (ETTC).
The last mod I argue, is the EGR mod. This disables the exhaust gas recirculation, which is meant for emissions, and therefore this change is for off-road use only. This mod is designed to prevent the super heating of the numbers 5 and 6-cylinder, which could result in burnt valves.
How much power is going to my car on BPU (TM)?
It varies from car to car, and the conditions andTuning. Most of the BPU (TM)-only Supra Twin Turbo, Dyno 370-410 hp to the rear wheels. This is usually at moderate temperatures, reaches a reset control unit (ECU's nothing wrong with have learned to delete), and often a bit 'high-octane leaded fuel un-tender. On the road, power is reduced, especially in bad weather, but at least 90 percent of the electricity should be maintained.
What type of 1 / 4 mile ET and trap speed I run at BPU (TM)-only?
It is very differentdepending on the driver's skill. And the track conditions, the height above sea level, temperature, moisture and pre-race preparation. But most are between 12.3 to 12.9 with ETS 112-119 mph trap speeds on street tires. Times may also fall into the 11s with drag radials, a good driver and good conditions, as well as a good preparation before the race.
What is a BPU (TM) 'd Supra TT top speed?
High speed in the middle of 180 hours mile range should be achievable. Once the speed limiter isDisabled by the fuse "TRAC" naturally.
If the life of my engine and transmission negatively with the (TM) BPU mods to be affected?
Yes, but not a significant amount. If the vehicle is properly maintained and the car is treated with a certain respect for the components, you should keep most of the transmission's life. Which, given the fact that the Supra is by far one of the reliable and durable sports car, it will take longer than most sports cars by STOCK.be the only transmission components that a significantly reduced life expectancy to see the stock clutch. It will more than likely, not much longer than 8-10k miles once a BPU (TM). This is particularly true when the car runs at high speed is repeated under the age of 5 and 6 gear at full throttle. If your stock clutch has high mileage on it, or is slipping already, you should plan a new high-performance clutch. The stock turbo is subject to some 'shortenedLife (however brief on how you drive and maintain the car and the increase in performance)
Regarding the reliability of a 600hp Supra Turbo?
Chassis, suspension and electrical components should be driven only a minor impact on the reliability on the road Supras. The stock 2JZ-GTE engine should be taken quite well to this result. How long depends on maintenance, and how hard drive, and how often. But typically Supras can go for years in this performance. L 'transmission reliability will depend on whether it is an automatic or manual. A stock will not automatically take much power you will need a built-in gear, and its reliability depends on the design and construction. The handbook should keep 6SPD great, and the rear differential and axles.
The only concerns the actual reliability at such low levels that surround the actual changes that would result. Without the installation of the components used in deficits,also very high quality of those who may fail factory component reliability, as opposed to the compromises that exist in more constructed, more on the side of performance, reliability, final (Remember that we are talking about a Toyota, that extremely high standards of reliability) This may include fuel system components, turbo components, and especialy electronic wizardry. Basically a set-up that is either very well-designed, or components used as OEas far as possible without stressing about it, would be * * close to the reliability of the bearing. And the adjustment of components and component selection and grades, would play an important role.
What are the limits of the factory of various components (differentials, gearboxes, engines, etc)?
There really is not enough to really pin point failures is a limit to drive various components. The engine may fail to levels of network performance when he was running dangerously lean. Butwhen well tuned, both the internal (pistons, connecting rods, crank, cylinder head gasket, etc.) 700rwhp reliably. But of course these benefits, if the engine is not tuned-up and working properly, it is literally a bomb waiting to go, but it is also true with an engine built. Some owners have pushed their stocks inside the limit and have well exceeded 800rwhp, and even approached 900rwhp. I still do not understand how an oversized motor exceeded the bean counters at ToyotaCorporate.
The 6-speed Getrag is ridiculously strong for an OE transmission. His will is strong limit driving technique, such as starting to be affected, and whether the power is shifting. Even driven hard, the Getrag should hold quite well with 700RWHP. If there is a certain respect, they should be able to handle 800RWHP or more, although great care and respect must be practiced at these levels.
Differentials, axles, CV joint and drive shaftFailures are very rare. So I have a lot of information on the limits of failure. On the road tires, it would be almost impossible to break each of these components at all levels. Spinning the tires would come in before sending this type of pressure. The tires act like a switch. If you run drag slicks, this is not true, of course, but proved to 10 and even 9 seconds in this situation.
Will ride and interior noiseLow-end performance with a negative (TM) BPU mods to be affected?
Driveability is not compromised. Internal noise depends on the exhaust system you choose. Some do it much stronger, some even make it quieter. But most are just a bit 'stronger than stock. But that DBS is also in conjunction with the engine sounds much sweeter, so it's definitely worth it. And the inside of the Supra is pretty quiet anyway, so the main road, it will be much worth living. As for the low-endPower goes down-pipe to greatly reduce the turbo lag. So the low-end power and response is much better than the original.
If emissions trading negatively by the BPU (TM) mods to be affected?
As long as a high flow cat is used, emissions can not be done, and you must still pass visual inspection. If you run without catalytic converters, is at your own risk, and you do not pass the test or visual emissions.
Feed to be negative for the BPU (TM) involvedMods?
If you drive slowly, as in the light gas, mileage should not be significantly affected. Mileage will be significantly reduced, while the other hand, if you drive "vigorously", more power means more fuel burned I'm afraid.
If I made an 'aspiration "(Open Element Filter)?
The answer is a bit 'yes and no. The unit of stock filter is a throttle and an open vacuum would increase the potential flow. However, it will draw even more heated air in the engine compartmentmay reduce performance. My advice is, or the stock filter box, or install a cold air induction box, like the Max-Air. An added bonus is the open element filters that allow them to easily hear the primary turbo and bypass valve.
What about the stock intercooler?
The stock intercooler has a decent job up to 17psi on stock turbo, after which you will probably notice a significant profit, especially at higher temperatures, with a nice front mountCharge air cooler. But remember, there are some airflow to the center of the radiator, in addition to slightly decrease the response.
Should I use the factory rubber hoses with metal aftermarket intercooler pipes?
It would not hurt. It will not be of much help, either. If necessary, you can easily increase the throttle response, but at least it will seem more beautiful.
And the fuel system, injectors and fuel pump stock big enough for BPU (TM)?
Yes, this is the stock fuel systemvery safe and reliable to 450RWHP, although I would recommend a fuel pulsation damper bypass. All this, and I recommend checking dyno'd the car and with a wide band O2 sensor (not a cheap / F gauge stock on O2), the fuel ratio at your high boost setting. A ratio of 11.5:1 fuel would be safe.
What are the stock injectors rated?
540cc/min
Supra would have the advantage of a fuel controller?
BPU (TM) 'd Supras run a bit' on the richPage to go as far to reports of fuel. This hurts the power. What it does is a safety margin that makes engine damage through detonation unlikely. If you have a fuel controller, and tune correctly (tested with an accurate EGT gauge and a high-end O2 (The Stock O2 sensors are not accurate), then you should be able to provide a significant amount of energy to win . One of the most popular electronic fuel controller is the A'PEXi S-AFC. Fields SFC is also good.
What can I use to increase myBoost level, an electronic boost controller, or a CB manual?
With an increase in EBC is the safest way to increase, it will prevent spiking and over-promotion. But it really depends on your budget. If you can afford a business card to get one. If you're not, you go with a MBC. And keep an eye on the stress index. And whatever you use, be sure to increase control, do not get carried away, I would not recommend going regularly over 18psi.
What is the best electronic boost controller?
E 'There really is BEST. Although the A'PEXi AVC-R is a beautiful device, it offers much more control over other pulse EBC, but also more complicated to install and tune. The new flash is also nice. Most of the major drive manufacturers decent. Just avoid fuzzy logic models, if you still have the stock sequential turbo, are "confused" by the unnatural conduct of the sequential system.
When installing my EBC, connecting them is the turboWastegate?
The Primary Turbo is the only one with a wastegate. Full twin turbo mode, the thrust of the two primary turbo wastegate from the turbo is controlled. So, just take the basic school.
Some people say I have my ECU to be replaced with a re-programming, rather than just a boost controller. Do I?
Reprogrammed ECUs for the Supra TT are VERY $ $ $. You are in the range of $ 1200. And they have not shown that to provide a significant increase in performance orSecurity at BPU (TM) self-level. Its merit is shown, for vehicles with Turbo upgrade (s). Just be sure to purchase your ECU reprogrammed or have a reliable shop that knows what to do. And they matched to your car (mods and driving habits). And I'd also recommend taking a look at the AEM Programmable System.
What is a level of security to push BPU (TM) to run?
The general consensus is of 17-18psi. Some people have got higher, but I can not advise if younot have the money to replace the turbo / upgrade.
As rain is recommended?
The RMM (or Rod Millen Motorsports) Cat-less Downpipe is the most commonly used. But there are many other brands. Some down-pipes, as the case of DP Technology, have legal problems, high flow catalytic converter.
If a high flow cat hurt performance?
It will have some effect on performance, but not much. Its exact effect on HP is not clear, but probably costs a bit 'to hpmore, maybe 5-15hp at BPU (TM) power levels.
What is a down-pipe?
It 's the part of the exhaust system, the output of the turbine of the turbocharger is connected to the "cat-back exhaust system. The downpipe is where are the two catalysts, as well as the O2 sensor (or sensors in OBD-II cars) .
I have an OBD2 car. Can I still install a Down-Pipe?
Yes, but if the SP has a catalyst and a second location for an O2 sensor, will travelMy check engine light, unless you get one of those O2 "black boxes".
What are the strongest discharge?
The Tanabe Racing Medallion, and HKS Hiper Titanium seem to be the two most powerful systems.
What are the exhaust quieter?
The Tanabe Hyper Medallion, the cease and Tanabe G-Power Medallion (SP) GReddy Street Performance is the very least. Slightly less than full throttle, they are not stronger than stock. But at full throttle seem to "wake up" aBit.
What are some recommended exhaust systems?
It depends on your personal preferences. Here I want to break some of my recommendations on specific combinations of preferences.
Subtle Styling / very low cost:
Random Technology (75mm, full stainless steel)
Subtle Styling / Low Noise / affordability:
GReddy Street Performance (80mm)

Wild Styling / High SoundLevel / high cost / high flow:
HKS Hiper titanium (104 mm, the titanium silencer)
What is the cheapest way to replace the DP and Cat-Back?
Do you have a performance exhaust shop fabricate a complete 3 "exhaust system (Turbo-to-peak). It should also be priced under $ 400. And then you can use the silencer and tail pipe of your choice.
Which Fuel Cut Eliminator is recommended?
The GReddy BCC (Boost Cut Controller) is strongly recommended.
What does the fuel cut-offEliminator do?
The controller is factory programmed to enable fuel cut-off when boost pressure exceeds 14-15psi. He does so as a safety measure to prevent what the ECU sees the promotion. The Fuel Cut Eliminator effectively eliminates or at least the section raises a higher pressure. Reprogramming can disable this feature.
Which boost gauge is recommended?
The pulse measurement of high-quality work just fine. Accuracy is important to find the function. Auto MeterThe lessons are a good value. The lessons of Japan, A'PEXi, GReddy, HKS, etc., have more features but at a much higher price.
Where can boost gauge installed on the inside?
If you wish to mount to the dashboard, are the two most popular places of the town clock (which has a caliber 52 mm) and the air intake next to it (which has a 60mm gauge). It is also possible to measure the A-pillar pod.
What is the stock boost pressure?
11-12psi
Cam Gears are a good change forthe Supra TT?
Yes, they have shown that the increased supply of over 5 15rwhp BPU (TM) 'auto d. But to extract their potential, you need to do is vote, with a competent tuner to the test. And most of the increases in power output will be seen. I also recommend buying cam gears, the function of 5-pin.
Are being pulley (s) is a good change for the Supra TT?
Most of the crankshaft pulley requires removing the factory torque.
This is given byMKIV.com ". This is not an external (harmonic) balance, because the engine is fully balanced, but dampens both the axial torques produced by the ignition pulse, the bending moment and radial belt accessory
Basically, this device offers a great interest, the isolation between the motor and engine accessories. However, the removal of a 10-15rwhp win, but usually no charge for use in the long term.
Do I have upgrade the ignition with the upgrade toBPU (TM)?
The ignition system is stock can provide enough fire for a BPU (TM) 'auto d. The stock ignition system uses 6 large coils, one for each cylinder. So, support the system, the levels of HP impressive. You may need to switch to a colder range plug with a narrower gap (see below).
What about the connectors at the BPU (TM) or more spark?
Basically you want to plug similar to Creative Commons, but a series of heat cooler and a smaller gap. L 'Stock plugs are NGK BKR6EP-11 (2978), and platinum are inclined and have a .044 (1.1 mm) spacing. The ideal substitute for a change Supra NGK BKR7E (6097) would be. It is a cooler in the series (the "7"), it is platinum tip (the lack of the 'p') and has a smaller gap 0,0,315 thousand (lack of "-11"). This connector is also called the NGK 6097 and they are quite cheap. Platinum tip plugs are not desired for high power applications, Iridium plugs are more preferred. Unfortunately it seems that itsBKR8E one that could be better for high HP Supras.
Another good plug IK22 Denso Iridium IK24 or try. These candles can last more than NGKs above, but are also six times more expensive. The stock replacement plug would be the IK20, IK22 is the cooler one step, and the IK24 is two steps colder than stock. The IK22 would be good for ~ 400rwhp to 600rwhp. The IK24 would probably be a good choice in that regard. Two other connections are used frequently, the NGK 3330 (BCPR7ES), thediffer significantly from the terms of the stock NGK plugs 6097th Rapid Fire # 5 was once very popular but are more expensive, not last so long, and I fell from grace. These two connectors are known in a slight stumble down. Plug in Supras do not live long, usually around 5000-10000 miles. Therefore, recommend replacing it with every oil change.
What is the HKS VPC and GCC?
This is an electronic device that electronicallyphysically removes the highly restrictive mass air sensor from the intake manifold. VPC stands for Vein pressure converter. The HKS GCC is a device that further development of the VPC allowed.
I need a blow after off-market?
It is not mandatory, but it's a good idea. The bypass valve factory is subject to errors, and an aftermarket BOV is probably a wise investment for the line of turbo boost compressor damage prevention. It also sounds cool. It should be noted, however,if you still have the factory mass air flow meter, a blow-off valve that is downloaded stumble atmosphere, resulting in between the layers.
I nitrous oxide on the Supra TT, even though I already BPU (TM) power levels?
Yes Most people run 50-75 shot wet manifold systems. If you want to run on a more widespread use of this, you should consider a well-designed direct port. I so much as a shot-200 used one of these systems, and as a power supply system updatedwould be a must.
450 hp is not enough, what can I do?
Oh, the possibilities are basically limited only by your imagination and your budget. They know what they say, speed costs money, how fast you want to go?
The real power is in Single-upgrade and twin-turbo and the options are limitless. You can build a mild motor that puts out 450 rwhp all day with the immediate boost response, or a monster 1000 + rwhp.
Unfortunately, things always startdifficult after simple BPU (TM) changes. The change is more than "bolt on Downpipe, gain 50hp. Things like tuning, parts selection and combinations of matching shares to become much more important. However, this complex is the case with other cars HP. In fact, even exceptionally high performance, the Supra TT made it even easier to power than almost all other sports to be extracted. But we must remember that it is easy to be like (TM) BPU bolt-ons.
If youjust want something to toast the annoying Viper GTS. Then, on a mild single turbo upgrade (T04S04, T60-1, SP57-SP61) to concentrate. Along with this, you should have a front mount intercooler, a fuel controller, fuel pulsation damper bypass and measure EGT. This assumes you have all the BPU (TM) mods done more BOV, EBC, Cam Gears. With humor and some small things, you should be able to 450-500 rwhp (490-580 crank HP) figures, while the condition on a stock fuel system (this is in largeCondition). This would be a total investment of about $ 6,700 - $ 11.500 motor and electronic components (including the right lessons). If you already have (TM) BPU mods or FMIC etc. They spend less than they are. The price difference reflects the cost of replacing parts of the higher end and the addition of an HKS VPC to restrictive stock MAF.
The next step would be a power supply system fully updated and recommend performance cams, and other electronic devices(Engine management programs such as the AEM, or VPC / GCC / ECU combo, etc.). This would make much larger turbo and injectors. You can make more than 700RWHP on the field with no place for internal engine parts with strong, even with these benefits if they are properly adjusted and maintained, you should have a healthy dose of confidence and still keep in stock interior, as some have Black 800RWHP level while still running stock bottom ends in theirSupras. If you choose to go ahead and build the bottom end, then the sky is the limit on the power goes. So make sure you have a partial selection, installation, and tuning carried out by competent and experienced people. While this should apply to all levels of editing.
Should I get a Turbo Timer?
Absolutely. If you do not mind sitting in the car while it is in stand-by every time you turn off the machine. A turbo timer keeps the engine running for a presetTime as soon as you turn off the engine. You can remove the keys and lock the car and not worry about her, turns itself off. This is important for the life of the turbo. If not the turbo be given time to cool, it can be locked to the overheating of the oil and cause coking oil flow to the turbo bearings and seals and damage Koch.
Like most of the superstructure, the power is influenced by changes in ambient temperature?
Very clearly, like most turbo cars,Supra Twin Turbo can be very sensitive to temperature. Especially with the stock turbo and intercooler. On a (TM) auto BPU, would not be surprised, a reduction of 10 percent between the temperatures 50-60deg and 90deg temperatures to see his
If the bearings of the clutch and hold the power levels of the (TM) BPU car?
Depends on the condition and wear of the joint bearing. If it is in good condition, yes, you hold the power button, not bad at all, even if the experience of clutch slip, whileFull speed in top gear as the fifth and sixth. If you mean hard drive, often run at high thrust, then the life of Stocker will be significantly reduced. You'll be surprised if an extra 10,000 miles after BPU (TM).
Can I show my flywheel when replacing the clutch?
It is not recommended. Buy a new Toyota flywheel.
Can I use a light flywheel?
Yes, but be aware that they create a lot of noise to a minimum, and can transmit more vibrations andShock for the Getrag transmission expensive.
Why TRAC takes the security advantage over the off switch on the center console?
Just press the "Trac Off" button is disabled in part to the Trac system. We move to delay the throttle body Trac and TRAC funtion through the ABS system (only about 93.5 to 96), but not the Trac system, the time the function switch. Trac pulling the fuse eliminates both functions, and the speed limiter 155 km / h, which acts asthe trac system. The fuse can be found in the main fuse box on the driver's side of the engine compartment. It should be noted that removing the fuse to keep the lead TRAC light, but you get used to it.
The TRAC system to improve the cars performance?
NO. On-Trac system was calibrated to improve traction in adhesion. It has not been calibrated for performance in mind. When the Trac system detects a loss of traction, it is dramatically on the hard, cutting power;that will do nothing but hurt the performance. I would not rely on the Trac system for stability at high speeds when you lose control, it would be too slow and cumbersome, and would more than likely hamper your efforts to regain control.
How do I remove the factory 155 hours mile speed?
Remove the fuse for the Trac system. The speed limiter works through the throttle body Trac.
What is faster than Supra TT Trac with the fuse removed?
There are someDebate on this issue. There are rumors that 180 can be achieved. But with the numbers 168-172 mph stock form seems possible.
What is the maximum theoretical speed Supra TT? There may be more than 200 km / h with sufficient power?
Lets find out.
The Supra TT with the engine 6-speed has a stock redline of 6800rpm and a sixth gear ratio of .79:1 with an axle ratio of 3.13:1. Now we multiply our sixth gear ratio times our rear axle ratio, and we find our final gear ratiois 2.472:1. Now we divide our total reduction ratio of 2.472:1 6800rpm and we find our rear axle and the wheels are turning then to 2751rpm to 6800 rpm.
Now we calculate our tire circumference. The section width is 255mm rear tire, and the side wall of the ratio of 0.40, and our sides are 102 mm. Now, convert this to inches, divide this by 25.4, which is equal to 4.015 inches. Now multiply that by two because we have two sides that form the wholeIn diameter, and add the wheel diameter of 17 ", and we see a diameter of 25.031 cm. Be ', discover our size, you multiply the number times pi (3.14), and find that the amount is 78.59 cm , now sharing convert up to 12 feet. And we get 6.549 meters in circumference.
Now we multiply the speed of rotation of the tires, the tires of the outer periphery, and we find that the tire is 18 016 feet per minute, divide it by 5280 feet in a mile, and weWe found for 3.412 miles per minute, now multiply that by 60 minutes in an hour, and we find we are traveling 204.7 mph @ 6800rpm in sixth Transition. If the engines redline is increased 7500rpm, it is often due to an increased flow turbo. Then our maximum speed would be 225.8 miles hours, because, of course, plenty of power.
