upgrading the fpr, fuel rail and fuel pump are essentials in turboing whatever u guys are talkin about....do it right the first time as i said or you will be sorry


and for low boost (7 psi) an fmu is not fine.....i wouldnt run more than 4 psi on a fmu on my motor....if u blow your D series motor ok, just get 400 bucks and get a new motor....if i were to blow my motor.....thats about 2G's be smart, ive only heard bad stuff about the fmu
