yo, i have a d15b7 about to be turbo'd, question 1 is, i have a .42 t3 w/ a internal 7 psi wastegate, a few of my friends said that if im only going to push 7 psi then all i need is a 12:1 fmu, is that true?? one last question, on my t3, how do i mount an air filter on it, the front of it or whatnot where its suppose to go dont poke out or anything :/ any help will be appreciated

 

dont run a FMU, atleast get bigger injectors and AFC, or just AFC and uberdata to do it right, u mount the air intake fitler on the compressor side , where the blades are, a tube comes up fromt here and u mount it on the charge pipe, or just make a screen for it instead of a air filter

 

You could probably get away with the FMU but if you want to prolong the life of your engine and fuel delivery system, you'll do your engine a favor and atleast get a SAFC w/ 450cc injectors or uberdata w/ 450cc injectors.

Uberdata would be the best choice.

 

what they said....
don`t listen to "friends", most of time they tends to be wrong

 

you can use the FMU at 7psi.

 

you can but why when there's good free management available

 

on my t3 turbo though, rather than having a piece sticking out like | } to put a air filter on and whatnot, mine is completely flat in front of the blades

 

you'll need the factory flange for that..........what's this T3 off of?

 

Pics would help us identify it.

 

theres two pics of a turbo pretty much like mine
