Have evo3 16g what fuel mods do I need?

[vr4gasmtt]

Hello guys,

Been a long time since I last did anything with DSM's, and recently had the joy to drive my friends 97 GST which has an evo3 16g and a race tranny... he hasn't done anything with the fuel pump ever since he got the evo3 in, would it make a difference?

His car pulls pretty hard.

depends on what boost you are running. When I had the evo 3 16g on my gsx, i was experiencing fuel cut around 18psi. You really dont wanna go over that without upgrading your fuel system. I upgraded to a Walbro 255 and pte 680cc injectors,and pressure regulator
.

A must have would be bigger injectors(550cc would be good), AFPR, and a wally 255. That will help push that 16g to its fullest!

How far can one safely push the E3 16g with a stock fuel system + a Wally 190Lph?

I wouldn't run more than 12lbs , At the moment I am running 11 on my s16g and I am not going to push it any further until I get my injectors and 255 into the car.

If you are going to start upping the boost make sure you have a wideband and a datalogger.

i would say you can run about 14 PSI without any upgrades but with a wally 190 not to much more. U need to regulate your fuel with the AFPR and bigger injectors will help as well, just like tsihottie said

Injectors are a must and if you dont have dsmlink and know how to cheat and get away with not using a fpr then you also need a fpr like the other posts said. You can prob max out the 16g on that fuel pump, look into the fuel pump rewire its on the site. The rewire will give your fuel pump a nice jolt in the ass so to say. I ran 15 lbs everyday for like 6 months on a stock fuel system , just barely under factory fuel cut. I never had any problems but the same might not work for you so if your on the cautious side of things then i prob wouldnt do that.

 

[91TSIallday]

yup but if your going to spend money on a rewire kit just spend the extra little money and buy a 255 for 100 or look in the classifieds for everything you need, everyone is selling the things you need

On very low boost it is ok. I always recommend a 255 non hp and a set of 650cc injectors that way you can still run just an SAFC if need be. Also recommend a logger and a wideband to monitor knock and a/f. When you create a thread it automatically pulls up related one's. They are very helpful.

All that without searching.

Well, I'm running 680cc injectors, a walbro 190, and a rewired fuel pump.
I'm using and Evo 8 Ecu to tune, but with a 99, you can use EcuFlash to reprogram your car. No SAFC needed.

Yep get a upgraded fuel pump, and perhaps larger injectors you plan to tune with, I have 560cc right now, but im planning to get some more fuel. I also plan to get dsmlink, but i think until then i might get some 680cc to go along with my fmic.

with all those mods supporting the 16g and pushing about 18 psi... how much hp would a gst put down?

HP can vary due to different temps and in the tune as well.
Guesstimating around 250-280.

650 injectors rewired walboro 255 AFPR will make a big difference

i have to agree with afroeclipse and blackgsTurbo, this is a very common thread and easy to find, and Dsmj nailed that on the money! with a proper tune and mods around 300HP but with a FMIC, MBC, yada yada yada 300HP is in the near future
