alright i got a 89 crx si (d series non vtec) and i'm gonna do one of those homemade turbos....the engines got 160,000 miles on it so i figured i got to re-build it...i have already rebuilt the head soo for the bottom end. do u think i should just put stock parts back in because i will probably only be boosting 8-10psi or should goo like 8:1 compression and eagle rods and also i was wondering should i bore out my block? would that help even though i'm going turbo, i don't see y not?
