Forged Pistons for WRX
 

Hi guys this is my first post here...wanted to ask if possible what brands of forged pistons exist for the scooby....i have a 94 model WRX import...any idea what brands or possibly part numbers for forgies that fit this year of car...Thanks

The bore is common with all other EJ20 engines. And then you have oversize pistons as well. CR does vary though.

So you have the choice of STi pistons, but if you are breaking it down to that level (or have plans for a lot more BHP) then get some aftermarket forged jobbies.

Mahle, Wiseco, JE, Omega plus a few more all make them. One of the suppliers of said pistons who post on here will advise on costs etc.....
