The BPU (TM) cost? (BPU (TM) is a trademark SupraStore.com)

The basic performance upgrades. These modifications include: full length three inch down pipe (or with-out high flow cats), 3 "(75mm) or bigger cat-back exhaust system, raised boost (18psi), and the need to increase the cut eliminator (GReddy BCC) needed to achieve that boost without activating the factory fuel cut-off at 14-15psi. These are the changes that have been proven to provide the best HP-to-$ $ $ ratio.

+ What does it mean when someone says BPU (TM) +? And what is APU?

, which stands for extra power to produce change than the basic BPU (TM) changes. A "+" refers to the adj. Cam Gears and under-drive pulleys, the second "+" refers to a fuel controller, ECU upgrade, etc. For example, the Supra BPU (TM) changes, and front mount intercooler, will be called BPU (TM) +. If you added cam gears that, it would be BPU (TM) + +, and so on. "BPU (TM)" the term used until you have upgraded turbo (s). Then he called the APU, advanced performance upgrades. This designation pretty much covers any changes that may be performed.

who first engine modifications I should do?

I recommend starting with raising the stock turbo boost at about 18psi. This will require a quality boost gauge and boost cut eliminator (GReddy BCC). You will achieve the 15 or so PSI with the stock down pipe in place. It will provide an allowance of about 30rwhp. After changes are completed, it will be a logical next step to install the down pipe and Cat-Back exhaust at the same time. Now you'll be in full BPU (TM ).

What do the various "Free Mods" do?

There are many different "free mods" for the Supra TT. I'll cover only some of them ovdje.One will cover fall into three categories, boost control, EGR disabling, and TTC or True Twin Conversion.

Tri boost control mods are: the release of T-Mod, Mod clamps, and VSV Bypass Mod. Each of these changes raise raise without using boost controller. But you must keep a close eye on your boost gauge, and make sure that not allowing turbo boost too high (18psi is a safe level ).

The following modes are the true twin conversion mods (or TTC). This change prevents a sequential twin turbo, and causes the turbo to run constantly in parallel (and at the same time). This should allow for slightly better mid-range power (before the secondary turbo normally get on the internet) and provides a smooth power band, without a sudden increase in the boost caused by the transition from primary to secondary operation. However, this does not significantly reduce low-end power, and increases exhaust noise levels, and therefore can not be recommended on the street. Two types of TTC mod are traditional TTC mod which includes 2 methods, wiring facilities, or installing a one way valve, and electronic TTC MOD (ETTC ).

last MOD will discuss the EGR mod. This prevents exhaust gases, which is meant for broadcast, and therefore, this modification is for off-road use only. This mod is supposed to prevent the super heating of 5 and 6 cylinders, which may cause burnt valves.

How much power will my car make at BPU (TM )?

It varies from car to car, and the conditions and settings. Most of the BPU (TM)-only Supra Twin turbo, dyno between 370 and 410 hp at the rear wheels. This is usually achieved with moderate temperatures, reset ECU (to delete all the bad ECU may have learned), and often a little high-octane UN under the leadership race fuel. On the street, will be reduced, especially in bad weather, but at least 90 percent of energy should be retained.

What is 1 / 4 mile trap speeds and the aliens need to work on the BPU (TM)-only?

It varies depending on the skill of the driver. As the track conditions, elevation above sea level, temperature, humidity, and pre-race preparation. But most fall between 12.3 to 12.9 ETS with 112 to 119mph trap speeds on street tires. Time may be dropped in the 11s but with the drag radials, good driver, and good conditions, as well as adequate preparation before the race.

The BPU (TM) 'd Supra TT top speed?

Speeds in the mid-high 180mph range should be achievable. After a quick limiter is disabled by pulling "TRAC" fuse naturally.

be my life and transmission adversely affect the BPU (TM) Mods?

Yes, but not a significant amount. If the car is maintained properly, a car is treated with some respect for the components, you should maintain a lot of power train life. Which considering the fact that the Supra is by far one of the most reliable and durable sports cars, it will last longer than most well maintained sports STOCK automobila.Samo Drivetrain components that will see a significantly shortened life would be a stock clutch. This will more than likely not last much longer than 8-10k miles on a BPU (TM). This is especially true if the car is as quick repeated runs using 5th and 6 speed at wide open throttle. If your stock clutch has high mileage on it, or is already starting to slip, you'll need to plan a new high performance clutch. Also turbo shares will be subject to a somewhat shortened life span (how short will depend on how you drive and maintain a car, as well as how you will increase the run)

What is a reliable 600hp Supra Turbo?

chassis, electrical, and suspension components should see little impact on the reliability of the street crossed Supras.2JZ-GTE stock engine should hold up pretty well these forces. How long depends on maintenance, and claims that drive it, and how often. But typically Supras can go for years on this razini.Pouzdanost energy transfer will depend on whether it is automatic or automatic ručno.Dioničko will not hold so much power, a built transmission will be needed, and it's reliability will depend on the design and construction. 6spd Manual should hold just fine, and the rear differential and axles.

The only real reliability refers to the low power levels that surround the actual changes that are performing. Excluding installation deficiencies, the components used, even very high quality ones, can lead to fall short of the factory component reliability, as built in compromises that exist in all, was lean more towards the side of ultimate performance, but the ultimate reliability (Keep in mind it comes to Toyota here, whose reliabilty standards are exceptionally high) This may include components of the fuel system, turbo components, especially electronic wizardry. Mostly set-up that was very well consistently, or using OE components as much as possible, without over burdening them, would have a * code * stock reliability. The tuning components and component selection, and convenient, could play a major role in this.

What are the power limits of the various plant components (differential, transmission, engine, etc. )?

There really are not enough failures really pin point the time limit for various power-train komponente.Motor could succeed in a factory power levels, if it is running dangerously lean. But when well tuned, the internal engines (Pistons, rods, crank, head gasket, etc.) are reliable to 700rwhp. But, of course, at these power levels, if the engine is set-up and configured properly, it is literally a bomb waiting to go, but it will be just as true with a built engine. Some owners have pushed its shares to the inner limits and well exceeded 800rwhp, and even approached 900rwhp. I still do not understand how this engine is built over the past made ​​bean counters at Toyota Corporate.

6-speed Getrag is ridiculously strong for the OE transmission. Its borders will greatly affect driving techniques, such as running and whether or not power shifting is used. Even the hard, Getrag should hold quite well with 700RWHP. If you treat it with some respect, it should be able to handle around 800RWHP or more, although great care and respect must be practiced at these levels.

differential, axles, CV joint and axle failures are very rare. So, I do not have much information on their failure limits. On street tires, it would be almost impossible to break any of these components on ANY snagom.Gume would spin before they would put the plant under such pritisak.Vrsta tires act as a fuse. If you start the drag marks, this is not true, of course, but they have proven to be 10, and even 9 second capable.

be drivability, interior noise levels, and low-end power adversely affect the BPU (TM) Mods?

drivability is not adversely affected. Interior noise level depends on the exhaust system you choose. Some will make it much louder, some will actually do it quietly. However, most are only slightly louder than stock. But DBS also added in combination with a lot sweeter exhaust note, so it definitely pays off. The interior Supra is pretty quiet anyway, so on the freeway, it will be quite bearable. As for the low-end power supply goes, down the pipe will be greatly reduced turbo lag. Thus, the low-end power and response is much improved over stock.

emissions will adversely affect BPU (TM) Mods?

long as a high flow cat is used to show should not be done, and you should still pass visual inspection. If you run without catalytic converters, you do so at your own risk, and you would not pass visual or emissions testing.

Will fuel mileage adversely affect BPU (TM) Mods?

If driven calmly, as in the light throttle, mileage should not be significantly affected. Mileage will greatly reduce the time, however, if you drive "vigorously", more power equals more burned fuel I am afraid.

Should I install the "input" (Open element filter )?

This is a little yes and no answers. Assembly of the stock filter is a flow restriction, and the open part of the intake will increase the potential flow. However, it will also attract more hot engine compartment air, which can hurt performance. My advice is to either modify the stock filter box, or install a cool air induction box, like Max zraka.Bonus open element filter is to allow you to easily hear the primary turbo and by-pass valve.

What is the stock intercooler?

stock intercooler does a decent job until about 17psi on stock turbo, then you will probably notice a significant gain, especially in warmer temperatures, with a nice front mount intercooler. However, keep in mind that it will block some airflow to the radiator, and slightly reduces the response.

Should I replace the factory rubber intercooler hoses with aftermarket metal hoses?

It would not hurt. But it will not help much either. At most you may slightly increase throttle response, but at least it will look nicer.

What is the stock fuel system fuel injectors and pump large enough for BPU (TM )?

Yes, the stock fuel system is very safe and reliable to 450RWHP, although I would recommend a fuel pulsation damper bypass. Anything more, and I highly recommend the car dyno'd, and using wideband O2 sensor (not cheap / F meter is connected to stock O2) to check the fuel ratio at high boost settings. 11.5:1 would certainly fuel ratio.

What are the stock injectors rated at?

540cc/min

Would the Supra uses of fuel controller?

BPU (TM) 'd Supras running a little on the rich when it comes to fuel ratios go. It might hurt. What to do to ensure border security that makes engine damage through detonation unlikely. If you get a fuel controller, and to set up properly (the Dyno, with accurate EGT gauge, a high band O2 (Stock O2 sensors are not accurate), then you should be able to gain a noticeable amount of energy. One of the most popular electronic fuel controller A'PEXi S-AFC. fields SFC is good too.

What should I use to increase my boost level, Electronic Boost controller, or manually before Christ?

Using the EBC is the safest way to raise boost, it will prevent spiking and over-strengthening. But it really comes down to your budget. If you can afford EBC, get one. If you can, go with a MBC. I always keep an eye on the boost gauge. And whatever you use to control boost, remember not to get carried away, I do not recommend going regularly over 18psi.

What's the best Electronic Boost Controller?

Actually there is no best. Although the A'PEXi AVC-R is a nice unit, it provides much more control over the increase in comparison to other EBCs, but also more complex to install and podešavanje.Novi Blitz unit is also nice. Most major manufacturers make decent units. Just avoid fuzzy logic, trim, if you have a sequential turbo stock, they will become "confused" by the unnatural conduct of successive systems.

When installing my EBC, I have to connect it to both the Turbo's Wastegates?

Primary Turbo is the only one with a wastegate. When the full-Twin Turbo mode, turbo boost both regulated by the primary turbo's wastegate. So, just connect it to the primary.

Some people say that I need to replace my ECU with a reprogrammed one, instead of just using a boost controller. Do?

reprogrammed ECU for the Supra TT is very $ $ $. They are in the $ 1200 range. And they have not been proven to provide significantly increased performance and safety on BPU (TM) level car. Their merit is shown on cars with upgraded Turbo (s). Just be sure to buy your ECU, or have it reprogrammed by a reputable shop that knows what they are doing. And it fits to your car (driving habits, and modes). I would recommend taking a look at the AEM system programming.

What is it safe to increase the level run at BPU (TM )?

the general consensus is 17-18psi. Some people have to be bigger, but I do not recommend it if you do not have money for turbo replacement / upgrade.

Which Down-Pipe is recommended?

RMM (or Rod Millen Moto) Cat-less Downpipe is the most widely used. However there are many other brands. Some down pipes, such as the Random Technology DP, feature emissions legal high-flow catalytic converter.

will be a high flow cat hurt performance?

will have some impact on output, but not much. Its exact effect on HP is not clear, but it probably costs a few hp at most, maybe 5-15hp at BPU (TM) power level.

What is the down-pipe?

This is part of the exhaust system that connects the output of the turbocharger's turbine section of the "cat-back" exhaust sustav.Downpipe is where the two catalytic converters are located, as well as the O2 sensor (or sensors in OBD-II cars) .

I have a OBD2 car. Can I still install a down-pipe?

Yes. But if the DP has a catalyst, a second place for the O2 sensor, you will trip your check engine light, unless one of those O2 "black box ".

, which depletes the loudest?

Tanabe Racing Medallion, and HKS Hiper Titanium seem that the two loudest systems.

, which depletes the quietest?

Tanabe Hyper Medallion, abolished Tanabe G-Power Medallion and the GReddy (SP) Street Performance seem to be the quietest. In something less than full throttle, they are louder than stock. But at full throttle it seems to "wake up" a bit.

What are some recommended exhaust systems?

What is the cheapest route to replacing the DP and cat-back?

are custom performance exhaust shop making a complete 3 "exhaust system (Turbo-to-Tip). It should cost less than $ 400. And then you can use a muffler and exhaust tip of your choice.

Which Fuel Cut Eliminator is recommended?

GReddy BCC (Boost Cut Controller) is highly recommended.

The Fuel Cut Eliminator do?

The factory ECU is programmed to activate the fuel cut if the manifold pressure exceeds 14-15psi. It seems like a security measure to prevent what they see as over jačanje.Eliminator ECU fuel cut effectively eliminates or at least raises the cut senior tlak.Reprogramirati ECU can also eliminate this function.

Which boost gauge is recommended?

Any good boost gauge will work fine. Accuracy is an important feature to look for. AUTOMETER gauges are good vrijednost.Japanski gauges, A'PEXi, GReddy, HKS, etc., have more features but at a much higher price.

Where can boost gauge be installed in the interior?

If you want to mount it in the dash, the two most popular places are the Sun site (which has a 52mm gauge), as well as openings for the air next to him (which has a 60mm gauge). You can also use sub-pillar gauge.

What is the stock boost pressure?

11-12psi

Cam Gears are a good modification for the Supra TT?

Yes, they have demonstrated that the 5-15rwhp get the car BPU (TM) 'd. But aside their potential, you must have them adjusted so knowledgeable tuner, the Dyno. And most will be able to get be seen on the exhaust side. I also recommend buying cam gears which have a 5-bolts.

under the drive pulley (e) a good change for the Supra TT?

Most of the crank shaft under the drive pulleys require the removal of the factory torsion damper.

This is the MKIV.com: "This is not an external (harmonic) voltage, and the crankshaft is fully balanced, which reduces the axial twisting couples produced firing impulses and radial bending moment izpojas accessory drive. "

Basically this device provides crutial insulation between the engine driven accessories, and a crankshaft. However, removing it can provide 10-15rwhp get, but at the price of long-term use.

I need to upgrade the ignition when upgrading to BPU (TM )?

Ignition stock is very capable of supplying enough fire for auto BPU (TM) "d.Sustav stock ignition uses 6 large coils, one for each cylinder. Thus, the system is capable of supporting a very impressive HP levels. Maybe you'll need to change the colder the plug area with tighter gap (see below ).

What is the spark plug, which is recommended at BPU (TM) or higher level?

basically want similar plugs as stock, but cooler heat range and a smaller jaz.Dionica plugs are NGK BKR6EP-11 (2978) and the platinum tip and 0.044 (1.1mm) gap. Ideal replacement for the NGK modified Supra would BKR7E (6097). This is one range colder ('7 '), a non-platinum tipped (the lack of "p") and has a smaller .0315 gap (lack of' -11 '). This amendment is also called NGK 6097 and they are quite inexpensive. Platinum tipped plugs are not desired for high power applications, Iridium plugs are more preferred. Unfortunately, they do not seem to BKR8E that could be better for high HP Supras.

Another good supplement to try is the Denso Iridium IK22 or IK24. These plugs may last longer than a specified NGKs, but are also six times skuplji.Utikač stock exchange will be the IK20, IK22 is one step colder and IK24 is two steps colder than dionica.IK22 would be good for ~ 400rwhp to ~ 600rwhp.IK24 will probably be a good choice beyond that. Two other plugs commonly used are the NGK 3330 (BCPR7ES) which differ much more than the stock specifications plugs from NGK 6097th Also, Rapid Fire # 5 uses the very popular, but they are expensive, do not last so long, and Fallin in favor. Both of these plugs is known to cause a slight rock at idle. Plugs on Supras do not live long, usually about 5.000 to 10.000 miles. So, I recommend replacing them with every other oil change.

What is the HKS VPC and GCC?

This is an electronic device, which electronically and physically removes the highly restrictive mass airflow sensor from the intake tract. VPC stands for Vein converter tlaka.HKS GCC is a device that allows further fine tuning of the VPC.

I need after market Blow off valve?

is not absolutely necessary, but it's a good ideja.Tvornica by-pass valve is prone to failure, and an aftermarket BOV is probably a wise investment for preventing damage to the turbo compressor surge. And it sounds great too. However, it must be noted that, if you still have the factory mass-airflow sensor, an exhaust valve that is vented to the atmosphere, may cause stumbling between shifts.

Can I run nitrous oxide on the Supra TT, even if I am already at BPU (TM) power level?

Yes. Most people run 50-75 shot wet manifold systems. If you want to run a shot of it, you might want to consider a well-designed direct port system. I saw how many 200-shots at one of these systems, and improved fuel system will be necessary.

450hp just is not enough, what can I do?

Ah opportunities are mostly only limited by your imagination and your wallet. You know what they say, speed costs money, how fast you want to go?

real power lies in the single and twin turbo upgrades and options are limitless. You can build a mild motor that puts 450 RWHP all day long with instant boost response, or a 1000 + RWHP monster.

Unfortunately, things begin to increasingly difficult after simple BPU (TM) changes. Change is becoming more of a "bolt on Downpipe, gain 50hp". Things like tuning, parts selection and arrangement combinations of parts become much more important. However, this is the case with any high HP cars. In fact, even at extremely high power levels, Supra TT is still easier to extract power from than almost any other performance car. However, one should bear in mind that it would not be as simple as BPU (TM) bolt-ons.

If you want something that will toast that pesky Viper GTS. Then focus on a mild turbo upgrade (T04S04, T60-1, SP57-SP61). In addition, you should install a front mount intercooler, fuel controller, fuel pulsation damper bypass and EGT gauge. This is assuming that you have done all the BPU (TM) Mods, plus BOV, EBC, Cam Gears. With tuning, and a few odds and ends, you should be able to pull 450-500 RWHP (490-580 crank hp) numbers while on a stock fuel system (assuming that it is in great condition). That would be a total investment of about $ 6,700 - $ 11,500 in engine / electronic components (also includes the proper scale). If you already have BPU (TM) mods or FMIC, etc., you will spend less than toga.Razlika in price reflects the cost of higher end parts and add HKS VPC to replace the restrictive stock MAF.

The next level would require a completely upgraded fuel system and performance cams would be recommended, and further electronics (programmable engine management, such as the AEM, or VPC / GCC / ECU combo, etc.). This will allow you to run a much larger turbo and injectors. You can make it past 700RWHP range without needing to replace the internal motor with stronger components, even at these power levels, if properly tuned and maintained you should retain a fair amount of reliability while still on stock internals, as some people are repressed 800RWHP level while still running stock bottom ends in Supras. If you decide to go ahead and raise the bottom end, then the sky is the limit as far as power goes. Just make sure that they are part of the selection, installation and adjustments performed by competent and experienced persons. Although this should hold true at any level changes.

Should I install a Turbo Timer?

Absolutely. If you do not mind sitting in his car while it idles down every time you turn the car isključen.Turbo timer keeps the engine for a preset time after turn off the ignition. That way you can remove your keys and lock up the car and not have to worry about it, it will shut down on its own. It is important for the life of the turbo. If the turbo does not give time to cool down, it can overheat the oil and cause coking which will block the flow of oil and damage the turbo bearings and seals to cook.

As far as Supra's output is affected by changes in temperature?

is very important, as with most turbo cars, the Supra Twin Turbo can be very sensitive to temperature. Especially with a stock turbo and intercooler. At BPU (TM) car, I would not be surprised to see 10-percent reduction between 50-60deg temperatures, and 90deg plus temperatures

Will the stock clutch hold down the level of BPU (TM) car?

It depends on the condition and wear on the stock clutch. If it is in good condition, it will keep the power pretty well, actually, although you May experience clutch slip while at full boost in high gears, such as fifth and sixth. If you drive vigorously, which means that running at high boost frequently, then life Stocker will be greatly shortened. Be surprised if you see an extra 10,000 miles after BPU (TM ).

Can I resurface my flywheel when replacing the clutch?

This is not recommended. Buy New Toyota flywheel.

Can I install a lightweight flywheel?

Yes, but be aware that they can create a lot of noise at idle, and can transmit more vibration and shock to the expensive Getrag transmission.

Why is pulling TRAC circuit useful than it just turns off the switch on the center console?

just pushed "Trac Off" button is only partially disables the system tray. This prevents the body trac gas and TRAC funtion through the ABS system (93.5 to 96 only), but Trac ignition retard function. Pulling the fuse trac eliminated both functions, as well as the 155mph speed limiter, which operates through a system TRAC.Osigurač can be found in the main fuse box on driver's side of the engine. It should be noted that removing the fuse will cause the TRAC light to stay, but you get used to it.

the TRAC system improve the performance of the car?

NE.Trac system is calibrated to improve traction in slippery conditions. It was calibrated with performance in mind. When the Trac system senses loss of traction, it comes on hard, cutting power drastically, and it will do nothing but hurt performance. I also would not rely on the system tray to provide stability at high speeds, if you were to lose control, it would be too slow and clumsy, and will more than likely hamper your efforts to regain control.

How can I remove the factory 155mph speed limiter?

Remove the fuse for the Trac sustava.Limitator speed works through the body trac gas.

The Supra TT with a top speed of trac fuse removed?

There are some discussions on this topic. There are rumors that 180 can be achieved. But going with the numbers, 168-172mph in stock form seems possible.

What is the Supra TT maximum theoretical speed? Can you go 200mph with enough power?

allows you to find out.

Supra TT with a 6-speed has a stock Redline 6800rpm motor, and 6 gear ratio of .79:1, with a 3.13:1 rear axle ratio. Now we multiply our six ratio times our rear axle ratio, and we found out our final ratio is 2.472:1. Now we are divided by our total 6800rpm gear reduction of 2.472:1 and find our rear axle, and thus the wheels are spinning at 2751rpm, the 6800 engine rpms.

Now we need to calculate our tire opsega.Stražnje tire section width is 255mm, the sidewall aspect ratio is 0.40, so our sidewalls are 102mm. Now, convert to inches, divide it by 25.4, and is equal 4.015 inches. Now multiply those two, because we have two sides make the overall diameter, and add the wheel diameter 17 ", and we see a total diameter of 25.031 cm. Now find our range, we multiply that number times pi (3.14), and we know the scope of the 78.59 cm, now divide that by 12 to convert to feet. and we get 6.549 feet of total volume.

Now, multiply our tires are spinning speed of the tires outside the scope of, and we think that the rubber covering 18,016 feet per minute, divide that is 5280 feet in a mile, and we are covering 3.412 miles per minute, now multiply that 60 minutes in an hour, and we have found traveling 204.7miles per hour @ 6800rpm in 6th speed. If Redline motors was increased to 7500rpm, which is often due to a larger turbo flows. Then our maximum speed would be 225.8mph, given enough power, of course.
