I'll let you know. It came off a 2.5 L gasser. the exhaust a/r is .48. so it should still spool.
I talked to many turbo shops and what they ran for me was close to that.
have to see.
why you only doing 9psi? crank it up to 13 or so, and dial the fuel. Gotta get use out of that turbo. I think the engine can handle it.
good to hear you got it done. congrate, post some pics pls.
