So what is in the 460hp (crank) Supra Package and how much does it cost? Easy.

** This Just Added to FAQ Section Because of Good Info **

1. Downpipe 2. A'PEXi N1 Exhaust System 3. GReddy BCC 4. GReddy Profec B-Spec Electronic Boost Controller 5. 60mm Greddy Boost Gauge.

Check out Zach Pruett's 1994 BPU™ (BPU ONLY) 6-speed Supra dyno above, 430 RWHP and 442 ft.lbs of torque to the wheels. This equates to 505 HP at the crankshaft. Look at the green line and see how smooth and flat that power curve is! A fluke? Ask Ryan Woon about his 1998 BPU™++ car that dyno'd 433rwhp at Vegas '99 in front of 50 people! That is 500hp at the crank my friend!!

APPLICATION: 1993 to 1998 Supra Twin Turbo

Some have asked, what type of 1/4 mile ET and Trap Speeds should be expected. Trap Speed is the easiest indicator of true hp, with ET being much more driver dependent because the times are heavily changed by a good "launch". With this kit installed properly your car should run from 111-118mph in the 1/4 mile. If you can launch your car to a 1.8 60 ft. time, you may well be in the 11's on drag radials.

What if I want to change to a different exhaust or boost controller or add other parts (air intake, turbo timer, etc.)? Good question. We have put together the BPU kit as a reference to what basic components you need to make the horsepower. There are no cost savings by purchasing the kit versus buying individual parts, so you can just put together your own BPU™ kit by purchasing parts and assembling your own package.

I have heard of BPU™+ and BPU™++, what is the difference? Answer: The first "+" comes with the addition of cam gears which can give you anoher 20hp. The second "+" in BPU™++ constitutes an "underdrive-pulley" which can give you another 5-7hp. These items can be added to your shopping cart by simply selecting them under the "engine" section of the website.

There are over 550 people with the BPU™ and BPU™++ kits installed to date. Because of various differences in the condition and testing methods the actual crank hp numbers vary from 450-500hp. Nevertheless, where in the world can you get this type of horsepower for this modest of an investment? No where but at www.suprastore.com!!

What about automatic twin turbo Supra, can I get the same performance? With an automatic you get about 5-7% less power to the wheels simply because the auto tranny robs some power, other than that your auto will be a C5 slapping machine as well!!! The automatic transmission has been proven to 500hp, so there are no tranny upgrades required to run this kit. We would suggest a torque converter upgrade for this lightning hard launches though!

Question: I don't really have the $1400+ available to me now for the complete 460HP BPU™ kit, so would it be possible for SupraStore.com to recommend a "staged" approach to reach BPU™ levels over time?

Answer: Absolutely!!! This is a common question and with all of us on budgets, often times it is difficult to purchase all of the parts at once. If you look at the BPU™ mods from a performance perspective then you will come to understand that raising the boost and helping to minimize exhaust restrictions are the greatest hp gaining modifications you can do to your car. We would recommend the purchase of a downpipe (they are all equal in regards to performance from brand-to-brand) and after market cat-back exhaust (all our Supra exhausts are cat-back). These two combined will free up the exhaust restrictions of a turbo car significantly, help spool up the turbos quicker with the elimination of the pre and main cat and add couple lbs of boost. These mods will yield approximately 45-55HP alone and have your car running right around 13-15 psi in cooler weather. It is possible in cooler climates that with these two initial modifications you may hit "boost-cut" (see GReddy BCC on electronics page for details) which would require you to purchase the GReddy BCC. So there you have it, Stage 1 mods (down pipe, exhaust and possibly the BCC). Stage 2 mods should consist of a BCC, electronic boost controller and boost gauge for monitoring boost. Stage 3 would be good to add an aftermarket blow-off valve and air intake system.

Question: My car is completely stock, are there any other modifications or preparations I need for my car before going BPU™? Mike - San Jose, CA

Answer: Great question Mike! Before modifying any car you need to make sure all the basics are in good working condition. Higher mileage (>90,000 miles) may not respond quite as well as lower mileage cars, but that should not stop higher mileage owners from getting big power. Remember the average gain from a stock twin turbo Supra to a BPU™ Supra is approximately 130hp!!! Typically, as long as the car has been maintained well, then there are no particular items one must address prior to going BPU™. If you have a 6 speed car, then upgrading the clutch may be required in the near future (especially if you have alot of miles on your current clutch) with the added power.

We do suggest changing the spark plugs and gapping them to .032" when you are BPU™ (helps minimize any high boost missing). A good quality copper or Iridium plug is a solid investment (we sell them both). Make sure you are using a good quality synthetic engine oil and high quality oil filters (Mobil 1 and Redline 10-30 are favorites in the Supra community).

What is the effect of this kit upon fuel economy? Your basic fuel economy will be relatively un-changed. Unless of course you are constantly using all that NEW power from our 460HP kit. At which time the fuel economy will drop in proportion to how much power you use. Standard daily driving there will be a very mild change at most.

Good luck and if you need to speak to someone who understands Supra's feel free to call us at your convenience.
