rb20 cam options?

[budderigs]

I seem to have hit a brick wall at 350whp with my rb20.

I was thinking maybe my stock rb20 cams are holding me back.

I have heard that rb25 and rb26 cams can be swapped into the rb20 head. but i never found a right up on it.

what needs to be done? do I need to get the cams out of a specific engine?
what can I expect from doing a bigger stock cam vs pon cams?

I am trying to get to 400whp on e85 with this setup.

i heard rb26 swap is a waste for what you gain. what is your setup currently running as far as mods and reaching 350whp

What is the rest of your setup?

From my research with RB20 cams it seems that it really isnt worth it as it shifts the already torque lacking power band further up, you'll make a little more peak HP but you lose a ton of low end. Look into optimizing your current setup before you start going after cams.

right now my long block is pretty much completely stock.

I have a ported stock intake, high flowed evo injectors (~600cc)
stock turbo manifold ported with greddy td06 20g turbo custom 2.5in down pipe
evo front mount intercooler.

as of right now im running 19 lbs on e-85 24 degrees total timing. and im at 70% dutycycle. I know my injectors are going to run out soon but I still have some room.
