2.5l WRX hybrid...

keaniegenie · 01-22-2006, 02:03 AM

Most can agree that it's the cams that hold back this combo. Some say the heads too. No doubt better heads can help, but how much? How much of a difference is a 2.5l wrx hybrid with STI cams vs. USDM STI?

I know there are other threads on this, but I haven't seen any that clearly state the difference of heads.

i heard that there is not much of a diff. from wrx heads to sti heads, moreso the cams. however that is what i have been told and i am not ready to consider it as fact.

from my understanding cams will make up fro the smaller ports on the WRX heads...of course you can get the P&P'ed...
