tech questions on a 2.5L swap on a 02 wrx
I am in the process of buying a 02 wrx w/115K miles for $2200, but here's the catch. It has a knocking motor, so i'm trying to clear some things up since i would like to put a sti short block in, instead of another 2.0L.
I take it that i can swap the heads right over from my 2.0L to the sti block, but i am curious in what year block that i need for this swap to go smoothly. also what block i would need that would handle some boost, since i do believe there is a few upgrades on this car already.
it have a full HKS exhaust, K&N air filter setup, much bigger TMIC, Aluminum radiator, Turbo timer, and looks like a brand new turbo.. is there anything else i may need for the 2.5L swap?
