Unfortunately, that pretty much sucks. Most of the rest of the US has access to 93 octane (calculated using (R+M)/2), which is more in-line with slightly-more-than oem boost levels. If you’re talking about big(er) power (eg. 600rwhp), there’s no practical way to achieve that power level on pump gas.

Agreed.

Pardon me for being blunt, but that’s not specific enough. We can build your Mkiv Supra Turbo to the specs of 500rwhp OR 525rwp OR 550rwhp OR 575rwhp OR 600rwhp…but I can’t help you build it to a range. You have to pick one point …most likely the max you want to achieve… and then we build to that one spec.

PLEASE “hold your horses”. We haven’t even decided on a power spec yet. No need to jump to specific components.

If 2 different boost levels is one of your requirements (for whatever reason – I may ask for the opportunity to talk you out of this)…we can definitely include that in the specs for the build. Again, let’s not jump to any specific solutions yet.

Not necessarily. It depends what point you pick for your power goal.

For 500rwhp+, then the oem exhaust will be a restriction. However, note that you can do about 400rwhp with the oem exhaust with no issue whatsoever.

No – 4” is not required for 500rwhp. It’s also not required for 600rwhp. Another bad assumption on your part. I know you’re anxious to get going, but please keep in mind the Mkiv Supra Turbo has been built to pretty-much your specs (as I understand them so far) hundreds and hundreds and hundreds of times. I can get you where you want to go without any guesswork or redundant purchasing or any wasted $ in over-building certain components.

What am I missing? Didn’t you say 500-600whp above? How did we suddenly get to 1000whp??????

Not necessarily. This depends on your application.

Not necessarily. This depends on whether you pick 500rwhp or 600whp.

Wow – man are you ever getting ahead of yourself!!!! Internals – no way – the oem internals are good to 1000hp! Why on earth would you *ever* consider replacing them? Not “for now” – never. Got it? Regarding the valve springs, it depends on your application.

Hmmm. Again, the Mkiv Supra Turbo’s 183ci (!!!) engine cannot run high boost on your local pitifully low 91 octane pump fuel. We need to figure out some alternatives here, unless you want your 173psi compression numbers to plummet to 120psi or less. You decide…ok? When you do, we’ll figure out how to tackle the fueling issue. Even water injection (or preferably water+meth) would go a long way towards addressing the issue. If you care to check, I bet race fuel is quite easy to come by in Las Vegas. Let me know if you need a hand with this.

Again, you need to pick a specific number. 595rwhp? *shrug*

Not sure what you mean here…the map of the ecu? We might end up using the oem ecu…so sure – it could have a larger map area than we end up using… (?) Clear up what you mean for me if possible…

If you think you might want more, and your budget is flexible, just pick a number – even if you think it sounds crazy. We can build to your spec. Best to get you what you want right up front, instead of rebuilding it later.

Don’t disagree there are cheesy meth injection systems out there. There are good ones too.

Unless it’s been used on a 2jz-gte, I’d prefer you stay away from it. If your turbine wheel, compressor wheel, a/r ratios, etc. aren’t all matched to the application, a good turbo in theory might suck on an unusual application like a very high-boost potential 3L engine.

Ok, we’ll keep that in mind. If you pick 1000whp though (per your intercooler specs), don’t expect it to drive like a ‘benz. J

Not at all. Again, let’s take it one step at a time though (don’t get ahead of yourself).
