I'm leaning toward a T04, but I'm still open for suggestions. Goal is to get to the mid-12's, so I don't need anything too radical.

 

You can get into the 12s on any to4 turbo as long as the exhaust side is not too small. Get a 60-1(to4S) from cheapturbo.

 

agree T04S 60-1...get it in B.B. if you can 15% faster spool. get .86 A/R or bigger. don't for get to ensure it will fit what manifold you end up getting.

 

I have a TO4B .50 A/R .81 P trim, (14.5 PSI) stock porting 12.40 @ 103 MPH and totally missed 4 th with tranny oil on centerforce clutch and on 265/35/18 streets! PM your email I'll send cool video killing a stang on NOSand ET Drags.

almost anything bigger than I have will get you into 11's.

 

I say T78
