1000 rwhp
 

What is the best way to get to 1000rwhp "safely" without the car blowin up in my face( by the way I have a 1994 mkiv supra tt) I have seen some turbo kits/engine kits for the supra but what would be a better and safer method a parallel twin turbo or a single turbo and which would be quicker spooling and I am planning on a alchohol/meth injection because this will be a daily driver too. I already have wider fenders to accomodate bigger and wider tires for traction and what other modifications should I make like body, transmission wise because a guy blew his transmission when he was running his supra.

Is your '94 Supra TT a 6spd or auto?

Either way, the #1 way to do it "safely" is with race fuel. No way you can get that on meth alone, unless you fill your entire fuel tank with it.

After you've got it firmly fixed in your mind that you absolutely will need to run race fuel in your fuel tank (no pump gas at all), you'll also need a complete fuel system upgrade, a very large turbo upgrade, a standalone ecu w/ignition amplifier, and lots of dyno tuning.

Also, the oem 2jz-gte will handle 850rwhp (6spd), but for 1000rwhp you'll need to replace the connecting rods (preferrably with Carillos).
Both are just as good and just as safe and just as quick spooling. Of course, the single is cheaper, and with fewer parts in theory it's more reliable. If you want to dramatically increase spool of the big twins or the big single, you'll need to run nos.
Again, that won't be anywhere near enough to make 1000rwhp on pump gas. You'll need to either run pure meth in your fuel tank (and double the capacity of the aftermarket fuel system), or run pure race fuel.
How wide? Also, what kind of rubber do you run? There pretty much isn't a street tire on the planet that'll hook 1000rwhp...
Yep if you have an auto you'll need to swap it with a TH400 kit (Sound Performance makes a complete kit specifically for the Mkiv Supra TT, with a special TH400 designed to manage the variable power of the 2jz-gte with a big single).

The other mods depend on your application (drifting? autocross? highway pulls? 1/4 mile? standing mile? roadracing? 1/8th mile? daily driving? etc.)

Hopefully that info is enough for us to start a dialog...

Its a six speed and I'm not running any tires yet because I havent decided and I have seen other 1000 rwhp supras run on pump gas 93 octane and they didnt seem to have a problem and I have seen people achieve a lot of horsepower without race fuel.... This has nothing to do with the topic but is it true that the more displacement an engine have the faster the turbos will spool and that they will be more powerful, jw

I'm sorry to inform you that you have been badly misinformed. In other words, you really have not "seen" ANY "1000rwhp supras run" that power level "on pump gas 93 octane", because it's absolutely impracticable. If you can name even one Supra you think has done that, please post it here and I'll track down the truth for you...
Sure, it's possible to make big power without race fuel, but only with a HUGE displacement engine (eg. a $17,000.00, big block V8 that's been bored & stroked to about 10L (632ci) of displacement)...i.e. NOT with a little 183ci 6cyl 2jz-gte (Supra engine). The only way to make anywhere near 1000rwhp with a 3L engine is with big boost (either turbo, supercharger, or chemical (aka nos)), which means very high cylinder pressures, which in turn means you must either run high octane fuel or else you will detonate (and almost instantly wreck the engine). You can make big power with a 2jz-gte, but that power comes at a price ... and the first price you must plan on paying for that big power (eg. 1000rwhp), is for race fuel.

Personally I don't see the big deal. "Race fuel" is just different 'brew' of dinosaur remains. A 3L engine means you can still make 25+mpg on the highway (off boost, of course), which is something you could never do with a 10L big block v8. Sure the fill-up will be a bit more pricey when you choose to put down that 1000rwhp...but a 3L engine is lighter too, which helps overall hp-to-weight ratio!
It all depends on exactly what you mean by "faster" and "more powerful". If you mean "faster" in terms of 1/4 mile times (or time ticking on a stopwatch), then probably not (i.e. not "faster"). If you mean "faster" in terms of making power sooner in the rpm band, then maybe yes (even though a downshift instantly eliminates that advantage). If you mean "more powerful" in terms of total horsepower, then probably not. If you mean "more powerful" in terms of total horsepower at a given/specific boost level and octane combination, then maybe yes.

thanx for the info and answering all my questions and what octane race fuel should i use? By the way your extremely smart and basically knows everthing about supras and engines agan thanx for the help.

Glad to help.

The octane of fuel depends mainly on how much boost you need to run. To make 1000rwhp with a 6spd, you'll likely have to run about 32psi of boost (depending on turbo size, timing curve, tuning, cams, etc.), which means you'll probably need pure c16 (116 octane) fuel in the tank.

Ok so 116 octane fuel, what turbo size and what kind of turbos would you recommend and what would be any company that does the type of fuel system upgrade that I need to run and what other adjustments like strengthening the block or anything else I would need, btw how much does 116 octane fuel cost?

For 1000rwhp (6spd) you'll need a 76mm turbo. Sound-Performance is a great company to choose, since they've pre-matched & tested both the compressor and the turbine a/r to the needs of the 2jz-gte.
Sound Performance also sells fuel systems. I used to make and sell them too, before I started working 12+hr days at my new job...
Again, only the connecting rods need to be changed over 850rwhp. Everything else is just fine for 1000rwhp.
You'll need a different intake plenum - the oem plenum is only flow balanced to about 750rwhp or so. I like this one, by Virtual Works.
I'd guess about $9/gal...

One more thing what should I do to the tranmission I know you said to rebuild it but where should I go and what parts should I get to upgrade the transmission. I really dont like rollcages but I think it would be smart to put one in what would be a good rollcage that wont obstruct like when I get out of the car or anything else because I really dont want it to look like a full blown race car. what would be a good suspension upgrade

Really? If it's a 6spd, there's no need to rebuild, and I never said to rebuild it (see above "if you have an auto"). Several Mkiv's have run 1400rwhp+ through the 6spd getrag...Again, if it's a 6spd, don't "upgrade" it.You can't have it both ways...the best would be a fully custom cage.Again, what is your application? (I already asked you this question, at the end of post #2, above)...
