Is it a must to change the stock internals?
already have good prices for wisco pistons and eagle rods. building the intake and exhaust myself. lag doesnt really consern me. putting on a T72 turbo. 800cc injectors.
one big thing that i need to know. do i have to change the gearbox? its a 6 speed supe. twin turbo RZ. is 600whp at low boost enough for a 10 second supe?
want to use it for 1/4 mile and 1/2 mile runs...
ps.. i heard that if you boost lets say 1 bar with a T66 and 1 bar with a T72.. that the T72's 1 bar will be stronger than the T66.. i think its true because my logic tells me that the bigger turbo compresses more air into 1 bar than a smaller turbo... is that correct?

Nope the 2jz-g
te stock internals will handle literally anything a T66 will put out, assuming a sufficient amount of octane in the (race fuel) to match your boost level, and proper tuning.
In other words, do NOT waste precious upgrade $$$$ (re)'build'ing a 2jz-gte for anyting under 1000hp (yes, 1000hp!) at the crank, unless that engine has problems (eg. low compression/leakdown #s). Note that a T72 on very high boost (eg. 35+psi), together with a shot of nitrous, might exceed 1000hp at the crank.
The 6spd has proven it can handle up to 1500rwhp!
A T72 will have more power at 1 bar (because it is more
efficient), but it will also have more lag.
