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.
