Newbie questions (RB25DET)

[slixx]

Sorry for the obvious new guy questions, but my searches came up lame. I've seen some videos of some really impresssive Skylines and the HP they are making. I'm wondering what the real limitations are for the RB25.

Assuming good tuning, fuel, intercooling, adequate sized turbocharger, etc...

What is/ are the weak parts of the engine? I'm assuming the iron block can take at least 800HP. but what about the crank/rods/pistons/valvetrain?

I guess what my question is, what exactly needs to be replaced internally to support 600+ HP?

I'm in the planning stages of the 240SX swap is my reasoning, and I'm tired of Mustang this, Camaro that. (yes i know they are the cheap/ easy way to get speed)

look at page 2 of this RB Section for "Dyno'd the baby II" He made 587 at the wheels, 26PSI of boost. The part mod discussion is there as well.

I am probably just making half that power and can spin into 3rd gear. Good luck getting 600 to the ground.
