Im considering doing ewg.
Ive got 04 sti with 20g turbo, front mount etc and i have a guy interested in trading me some parts for ewg set up. He has all the gasket, tial 44mm with fireflange, grimmspeed up pipe, screamer pipe, and bracket for iwg block.
What else do i need? Any other parts, a tune to run the ewg or can i juat "slap" it one.
Ewg is new to me and if these questions seem retarded im sorry.
