fuel option

[99 gst spyder]

i have 16g w/ mani, fmic, and i'm planning to get 650 cc inj. along with walboro 255lph fuel pump plus using apexi safc neo and was wondering do i have to get th afpr kit now if i don't want to,but maybe some other times? plus

Yes, you should. Some people claim they can run fine without an AFPR if they have a 255lph, but most of them don't have a logger and can't see what the car is actually doing.

If you get a 255lph, get an AFPR. I'd also get a rewire kit for the fuel pump.

This information is correct. Get an AFPR with the 255 LPH fuel pump.

If you're going to run 650's and are planning on sticking with the 16g then I'd just get a Wally 190 or EVO8 202lph (14 volts) pump as that'll be more than enough and you won't have to shell out dough for an AFPR. Another option would be to just go with some 550's or EVO8-9 560's and a 190 or 202 lph pump dpending on what boost levels you're shooting for because 550's are much easier to reign in with an AFC than 650's.

I have a good 16g fuel set-up available that I'd be willing to make you a good deal on. It's a EVO8 fuel pump, EVO9 560cc injectors, 2G pocketlogger set-up with software and OBDII cable, and an AFC1 (dunno if you have the NEO already). I just figured I'd run it by you and see if you wanted it. You can PM me if you're interested.

so I can use 190 lph fuel pump and 550cc without geting a afpr? can i boost 20 psi and would it run right, and plus after fuel upgrade, i'm planning to tune it at the shop too, or do i need anything else before tuning.....

Depending on your airflow, 550cc injectors and a 190lph fuel pump should be fine. At 85% IDC the 550's should be flowing 3.13 lbs/min of fuel, assuming 43psi base fuel pressure and pump gas (.76 sg). Depending on your air/fuel ratio, that should be good for 31-35 lbs/min of airflow which is a good approximation of a 16g at ~20 psi.
