could you honestly see 400hp out of a 22r? I would say yes but with alot more work than what he says its capable of
I've seen a 1000hp 3rz. Not on stock internals, however. They are good for that 400 threshold, and not for long then!
lol any good check this built 2rz 1104bhp Celica by Paradise Racing. Borg Warner S500SX Turbo and a 2RZ-FE 2.4ltr HiLux engine! - YouTube and then check out his turbo setup http://www.toyotaminis.com/forum/build-up-project-threads-25/95-5-toyota-tacoma-2rz-boosted-4697/
