Assuming one had all the other bolt ons, udp, chip, camshaft and what not...what kind of power difference could one reasonably expect from RRM's stage 2 head? I had no luck finding this information anywhere else.

 

well a good reason to get it would be to keep your car running for another 100,000 miles. it says the ports are built bigger to make air flow better so you could expect a could amount of power over the stock. I suggest giving RRM a call, the guys are really helpful and could probably give you the best answer.

 

there is an entire thread dedicated to RRM's head that was started by ROCK himself. maybe that would be a good read for you since you require information about it?

 

since it was apparent you were having trouble searching on this site, here is a link to the thread I was referring to: https://www.evolutionm.net/forums/sh...d.php?t=247589

 

Sadly I have actually read that thread albeit I completely forgot I had. I also missed the 10-15% gain in power figure, my apologies. Thanks regardless!

 

no problem

 

Remember it is completely rebuilt so the head has performance advantage but on high mileage motors they need to restore efficiency again. That is where the value is. Guy under 40K should prolly look at doing other mods before you go do this.
