and ive herd that the RBs are much stronger than the 2JZ.
from what ive herd about the 2JZs you need to upgrade the internals to make much more than 400hp. supposedly all you need to do to an RB25 is drop the compression ratio and it will be able to handle 500+hp and an RB26 can make 600hp on stock internals
lol.... you heard wrong.
Figure out the facts before posting misleading messages. I had a 790bhp 2JZ-GTE with no internals at all, stock bottom end. Boosting 1.7 - 2 bar daily and put over 30k miles on the engine. I know of atleast 30 friends who make well over 700bhp on a 2JZ-GTE with no internals. It is a well know fact in the car industry that the 2JZ-GTE can produce mind bogging HP numbers before you even need to open up the bottom end.
S.W. in Austin TX put down 804 rwhp (Dynojet), circa 945 hp @ flywheel / 9.81 @ 153.58 mph on engine still unopened / factory internals.
next time... before posting... do some research.
