building engine.....
Hello i have bought a sti ra and the big ends have gone on it,i have a block of a wrx and was wondering if its ok to take heads of sti and inlet and use the wrx block?

i think i'm right in saying the sti block has better pistons and possibly rods??
so if your using the wrx block might be best to fit the sti pistons and just replace the bearings at same time while engine is out.
but if you just want to drop it in there should be no problems

and if it's got one of them I'm assuming it's a V1/2 and therefore has a closed deck block, so going to a WRX block is a downgrade, regardless of pistons. That said, you probably will never notice a difference at standardish power.

Your RA block more than likely has the under piston squirters, CDB is stronger, fit what you have ie the wrx short block, save up and get a good forged build done on the CDB.
5th injector was put on for Homolgomation purpose but is not connected to the ECU

If it's a CDB it will be pretty obvious from the outside because it has cross-hatching which the normal block doesn't particularly on the oil filter mount. Under piston sprays are nice as well. Definitely a better basis to do a build from.
