just wondering what issues i may run into/ what injectors to run to minimize issues for now.

just looking to upgrade my secondary injectors to either 750's or 850's

here's my setup: strait through 3" downpipe back exhaust, twin scroll removed, ported wastegate, msd 6a with timing retard, msd wires, k&n cone filter, hks FCD, hks F-CON (piggyback ecu), manual boost controller, emmisions removed, TB mod, walboro 255, AEM adjustable FPR

i'm hoping to run ~14 psi. will the bigger secondary's cause problems even with the piggyback?(fuel curve is adjustable) should i go with the 750's or 850's?

with proper tune, there is no problem to run either of them

well as i understand the FCON has a modified fuel map, but the only adjustability is shifting the fuel curve, it doesnt allow full tunability

14 PSI on a stock turbo?

With stock top mount, and stock turbo at 14psi? Not good.


I would sell the FCD and fcon, and pick up a RTEK.

i read that was the safe max stock turbo could handle, planning on running 10 psi normally. As for the rtek the fcon will do for now, bigger turbo and megasquirt are in the car's future

How did you fix the fuel pressure problem? That was you?

i narrowed it down to my fuel pressure regulator, it would work some of thetime and fool me but then stop working. so i bought an OBX fpr and it was full of metal shavings BNIB, so i have to return that and i'm waiting for an AEM pressure regulator now. so hopefully its solved.. haha

I agree on the tmic, but 14psi on stock turbo is no problem.
Ran that pressure for over 3years, untill i upgraded to bnr stage 4. Stock turbo is still in perfect condition..
