i have samco turbo inlet, and samco intercooler hoses, a upipe (no name), catback, thats pretty much it, but the big thing is i threw a rod last summer on this same setup and i replaced the shortblock with all oem subaru stuff, so i know i need a tune but i was waiting till i got my DP to do it. The only problem is a uneven idle or high idle when i start it in the morning. If i was running a Vf 39 or vf 43 turbo would i need a better fuel pump? im not sure if im running a stock pump or not i guess i should look. And no info from the seller i bought it through a dealer i know.
