Which path to go?

[cms9690]

I currently purchased a 95' gst completely stock, one owner, unmolested.

I have replaced the stock UIP, BoV, filter, and intake; all with parts from my silver DSM that hasn't been the greatest lately. So I have basically all the parts for building a good dsm-- inj,fp,safcII,FMIC,fmic piping, and a 16g ported turbo.-- My only dilemma right now is that I am at the understanding that the evoiii 16g needs a lot more fuel than the T25 and I wasn't sure if I wanted to do the fuel upgrade along with the a/f controller. Is there an alternative turbo that i can crank more than 15/16psi out of safely (no fuel cut) with only using boltons such as exhaust, piping, etc?

Of course I'm doing my own research about things, but I like to have some input also.

thanks,

14b.... but otherwise, I don't think you'll run out of fuel on the 16G at 15psi. What size injectors did you buy? 550's don't require as much screwing around as something much bigger. Id say take your time and put in everything you currently got, dyno tune it, and then enjoy. Well, enjoy until you get sick of 1 wheel peels, then sell it and buy an AWD.

If you go with evo injectors then you can crank and evo3 16g to 22psi safely (at least on a setup similar to mine) but I wouldn't go that route again. If you want a fast car without needing a lot of fuel then go with a 14b or a small 16g. They will spool much faster and flow very well. The e316g only flows about 4lbs/min more than a s16g and spool the same as a b16g. A b16g flows only 2 lbs/min more than a s16g and sacrifices a fair amount of spool and efficiency to do it. A 14b will spool even faster and will be as good a turbo as you can put on with 450s.

14b is the easiest to pickup and bolt on turbo you can pick up for our cars ($100 or so) As long as you stick around 13-15 psi you shouldn't get fuel cut unless your really pounding on it.

+1 on AWD!

With a logger and some careful examination you may find that you can run more than that up to the 17-18psi range but be careful to check your IPWs every time you make a mod that affects VE (exhaust, filter, IM, EM, IC, or anything that touches the air that at any point gets into the engine). The 14b is an underrated turbo that did a lot to put a lot of oldschool cars with stock fuel systems down the track very quickly.

You should be able to run 15psi on the 16g with just the stock fuel pump rewired. Or about 17psi on the 14b with the
fuel pump rewired. Don't even bother with the t25, there useless. My old fwd 1g flew at 17psi on the stock 14b. And
all I had done was uicp, ported to hell 2g mani/o2 housing, rewired stock fuel pump, and no exhaust after the downpipe. :)

[cms9690]

So, would I be able to bolt on the 16g on stock fuel as long as I kept it at the 15/16 range?

[the_mork]

With a stock pump, even rewired I would stick in the 14psi range. With an evo8 pump you might get away with running 15/16 without a FPR, an evo9 fuel pump you can definitely get away with 15/16 if your car is healthy but you will probably need an AFPR, mine certainly overruns and I just live with it.

I say leave it stock and mess around with your silver one.

I'm kind of in the same boat. I just bought a stock 99GSX and I was thinking of doing a few little things to it but I already have a couple cars for toying around with. So, why start another project car? Eh, those were my thoughts. Stock=reliable.

But, if your definitely going to mod it up and using a 16g turbo, I'd say get a 190 pump so you can get away with not needing an APFR. You said you had injectors. What size are they?

Not sure if your car is stick or auto. But, if it's stick rememeber to keep the clutch pushed in as little as possible. When at stop lights only push it in to get the car out of gear. When starting the car, only push in the clutch to start it and get it out of gear. Just to minimize the wear on the thrust bearing. Just a little tip...

I have 550's. I would like to mess around with the silver one but it is a wiring MESS! I would pay someone to fix it, but it's hard to honestly say what is wrong with it. But of course, I'm not a real mechanic myself..

Take it to an Autocross just as it sits and you'll find out what limits your car the most real quick. This will help you determine what you should really focus on because in general a fun autox car is a fun street car.

Good point... I'm thinking about replacing the brakes before I do any more engine mods.
