I'm having second thoughts about my fuel setup and would love to hear what ppl think about this idea.

I was planning on running the 2.87 pulley on my AUTO g35 using only 380 cc injectors, fmu, walbro intake and the inline pump (came with the vortech) and program it with the ss box.

Is this a good idea or am I way off? I recently have been reading post about the fuel pressure raising too high with bigger injectors and pump and now I'm afraid with this setup might not be good in the long run.

My other question is how safe is it to run the 2.87 pulley compare to the 3.12 pulley (10 vs 9 psi)? The motor is stock but will cranking 1 more psi goo boooom?

 

when I had a vortech I ran it with rc440's, walboro fuel pump, no FMU, and the greddy emanage. If I were you I would ditch the FMU and just use larger larger injectors (440's) with the walboro and split second box.

 

I know there is one or two guys running the 2.87 with stock injectors and stock Vortech fuel system . But G-man is right , it would be much less harder on the injectors running 440's and the Walbro pump .
