Help With My Rb20Det

[RB_GURL]

My friends building me a RB20det and i am wondering what is needed to get 400hp out of it (if thats even possible!).

He reckons he can get at least 400hp with full factory internals and says forged pistons are a waste of time and dont do anything.

Specs of motor so far:

WIll be running

- T3T4 garrett turbo

- Chipped computer

- Top mount manifold

- 32mm wastegate w/ 18 pound spring

- Front facing plenum

- Front mount

Wanting to know if i need forgies or not and also any examples of other high hp 20det builds

Any help/advice would be greatly appreciated!

400hp at the wheels or 400 hp at the engine?

400hp at the engine is pretty easy for a lil rb20 , your setup you detailed there sounds odd. oh and no need to even pull the head off a rb20 (have personally seen 280rwk out of a high klm shitter rb20 live a hard tortured life) , save the $$ for a rb25 or whatever

Thanks guys. Did some research and found that most people can get between 250-350 hp at the wheels but I'm more concerned about how long it will last, i'd like to have it running for more than a week before it decides to spit a piston or something just see what happens I guess!
