Minimum Fuel requirements for 20psi - SRT Forums

DMW · 11-04-2009, 03:04 PM

I'm thinking of turning up the boost on my car to say a 20psi spike and hold as much as possible on the stock unported turbo. I have a completely stock fuel system. I'll be using a FM WGA plus my DSP and custom Rage tune. At this point I've been thinking about what needs to be addressed fuel-wise and finding the most cost efficient setup.

Which of the following do I really need (if any) to keep my a/f ratio safe?
---------------------------------------
3 bar map/tip
S2 injectors
255lph fuel pump
Fuel pump rewire
Returnline

FP rewire is definitely a good idea no matter what route you take.

if you plan to go big turbo later get a returnline.

if you plan to stay stock turbo get some s2 injectors and call it a day

255 should come with turbo upgrade and 3 bars arent needed unless your want them for a specific application

rewire call it a day.....i ran 20+psi down the track with a 75shot and well my car still runs like a champ

yea rewire alone should get you some extra fuel on the stocker. 20 psi should not have a problem. remember its just a 20 spike, so the fuel system is fine once reaching 4-5-6k when your only 17-16 psi

Save your money and just get the 255/Stg2 injectors.

rewire is easy cheap and works.... he will be fine with rewire.

I would suggest a RL first. if you wanna spend some money...

If he intends on maxing out stock turbo, that's ridiculous and just blowing money.

Stage 2 injectors with a 255 is more than enough...plus if he gets meth down the line, forget it. I'm willing to bet a stock pump with stg2 injectors could do it just fine.

The rewire is a waste of money IMO. If you already have too much fuel then it's an even bigger waste

waste of what money???? cost me some spare wire and a relay????

it cost NOTHING....

Rewire got me almost.5 more afrs. back when i was stock turbo and stock fuel system i was trying to get all the fuel i could get.

Its not a bad mod at all

yea it all depends on what his future plans are...the stock fuel system should push around 20psi with a 255 and larger injectors(stg 2) you could probably get by on the 05 injectors(stg 1)
