ok i have a z6 manifold going onto my a6, now what FPR do i use, the a6 one or the z6...

 

up...need the answer please...

 

you can use either

what fuel rail are you using with the z6 mani?

i would stick with the same fpr for the same fuel rail

the z6 one will give you higher fuel pressure because its a Sohc Vtec fpr

so i would suggest to just stick with the a6

 

if u usin the A6 long block. use the A6 FPR.....
if u using the Z6 longblock use the Z6 FPR...... in other words. dont use the Z6 PFR unless u got vtec.,,, ull be running ricch......

 

well...i have a b&m fpr for it anyway, plus ill be having a crower cam, and the manifold will be ported, as well as the other air mods...(i/h/c/e)...

 

just make sure you've got the guage too so that you won't be running too rich or lean with that high compression and cam.

 

ok so i guess its a6 fpr with b&m attachment...
