So what is the best hybrid motor setup? The 2.5 rs heads on the impreza are a SOHC, but if i am not mistaken the heads on the 2.5 Legacy are DOHC. So when creating a hybrid turbo motor which bottom end and heads will be more benefitial for higher boost? joe

I have seen 2.5rs owners drop a legacy 2.2 bottom end with the 2.5 heads. Does the bottom end of the 2.2 drop right in without custom motor mounts?:wave:
