Just a quick question, i can get my old 2.5 legacy back (non turbo) Rreg, engine is low mileage and in mint condition, full subaru service history and full rebuild 5,000 mls ago, can i put this into my Rreg uk impreza, and will it on it's standard internals handle 300/320bhp ?.

 

without a turbo conversion i would have thought no.

 

Sorry i did mean full conversion, just asking about the internals .

 

Nope, pistons will be high compression so no good for a turbo conversion.

 

So wot else apart from pistons, can i use my heads etc ?.

 

The cams would not be ideal for turbo as NA uses different durations which would not be suitable for turbo.

 

Would imagine the liners on the N/A Open deck block will balloon/move under boost too.
