walbro 255 and stock injectors

[venom2097]

I have upgraded to a walbro255 and now am over running the fpr, I think. This was causing the car to hiccop (drown?) at ~4500rpm+. So I used the afc to lower the fuel 5% from 4000 up, that fixed the hiccoping, and the A/F gauge still reads rich in 4th to 7000rpm, so what I want to know is this going to kill my car?

honeycomb in full, screw not moved from factory position.
waiting on 660s and EGT.

also what are my options for an aftermarket fpr. I was looking at the B&M command flow, what others are available for a 2G??

even with 660s and an EGT your going to overfun the FPR.. get a FPR on the car and youll be fine

also if you can get your hands on a 1st gen fuel rail you can use the www.spoolinip.com FPR which is supposedly really nice but only for a 1st gen so far..

I'm not totally sure but I think in the old thread they said that the spoolinup was now available for 2g's. Not totally sure though. I'm hoping.

 

[larryd]

according to their website its still not available unless they havent updated it yet..

 

[RocketDSM]

Anyone know of problems fitting a 1g fuel rail to a 2g manifold?

 

[larryd]

one person said it fit fine with no problems and another person said it required slight modification but didnt explain exactly what but it wasnt a big deal.. should go on pretty easily

Dont' get a b&m fpr. You can't adjust the fuel pressure down. Get a spoolinup, (paxton, sx, or aeromotive) <--- all the same, different color.
They allow you to adjust up or down just like the spoolinup.

Did my FPR die? the following just started:

Car drives fine under about 10psi of boost, but after that the car makes a farting type sound from the exhust, boost increases but acceleration sucks. If I keep it at WOT at about 6K rpm and 18psi the car will accelerate normally and the farting stops. Then I shift and the car goes back to farting until once again 6K rpm.
No one in town carrys a fuel press tester for my car except the dealer that wants $80 to hook it up for 5 min.

 

[larryd]

do you have a gauge on yer FPR?? check what its reading at if you do..

 

[venom2097]

No gauge yet(will get one with my afpr), None of the local autoparts stores have the adaptor(?) needed for my car, or know of anyplace I can get one. I don't want to go to the dealer because the local one is kinda shadey and very overpriced.
Has a temp fix I turned the boost all the way down to ~12psi.

 

[larryd]

try www.jegs.com they seem to carry alot of the fittings though there site is hard to navigate

OK I said it in the other FPR thead and I will say it in this one. I bought a 1G rail and 1G spoolinup AFPR. It fit on my 2G with NO modification to anything. Fuel lines or timing belt cover.

Later,
