Sorry I don't understand. Why waste $ on "changed internal components"? The gt4202r is a 1000hp turbo, which perfectly matches the strength of the oem 2jz-gte internals.

Unfortunately, the way to improve 2jz-gte reliability at 1000hp has nothing to do with internals - it has to do with what kind of fuel you run. Run too low octane fuel (for a given max psi boost), and it'll detonate which ruins aftermarket or factory internals equally well. Run enough octane and your reliability is ensured. For 22psi max/peak, you'll need at least 100 MON octane to ensure reliability. E85 would do, and so would a very good meth/water injection system together with 93 R+M/2 fuel.

I don't think it's less reliable...it's just that it's (slightly) more complicated to work with. Also, choices for the intake-side aftermarket cams are more limited.

About $6,000.00 United-States Dollars (USD), from Toyota.

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
