Hey guys, I have a 1.9 American tall block with forged pistons, apr bolts, apr head studs, Burton stage 3 big valve head, Piper t285 cam n lifters,
Garrett stage3 t3 hybrid turbo with .48 housing and a
Grs Intercooler .
The question is do I keep the mfi set up and how restricted am I for bhp tuning wise?
or do I buy the efi setup as I have both heads?
does the mfi open up a much larger performance options?
