What to upgrade next?

[93 GSX TURBO]

I just joined so i dont know anyone, just gary from team Fuzion, what i wanted to ask is what i should upgrade now. My GSX is A/T so i had the smaller 3900cc injectors which I already upgreaded to 4500cc from a manual. I got 8.5mm Magnecores, K-N filter,255 Holley Fuel Pump, Fuel Pressure Regulator, so i dont knwo where to go from here, Any advice would help, Ive been into Gsx since i got mine like 6months ago

i was thinking about the boost gage, but which are thes best?

Autometer is fine. Just don't use that crappy hard hose.


Later on, you might want to install an EGT or something. Figure out a plan and see what you are looking at. If you don't care (like I don't) you can use an autometer boost gauge and a Greddy Peak/hold EGT (best out there). Just have to dremmel the hole to accept the larger GReddy. Both are white faced and come with amber lights or any other you can find. It is a simple light cover.


After you get that done. Think about the turbo or some more fuel/control.

You might want to put the 390cc back until have something like afc to tune with. Definitely boost gauge and mbc next.

I would also look around for a 14b to go with the larger injectors. The 13g is not a sufficent turbo for the enthusiast.

this guy at the performace shop i got to said that i wont have a big problem with injector change, just run alittle rich, but iam buying a afc in the next 3months, 14b or 16g too

that boost gauge is going to be put on hold, i need a new water pump belt and a valve cover gasket

1) Boost Gauge
2) Upper Intercooler Pipe
3) Shift Kit And End Clutch
4)torque Converter
5)2g Turbo Manifold
6)14b Or A Evo 16g If You Changed Torque Converter
7)safc

Like stated above, the AT ecu isn't programed for the larger 450cc injectors, put the smaller 390's back in until you have a MT ecu and/or safc.

does it really have a big effect if it runs to rich, what can be the consequences

my understanding is that it mostly just hurts your pocketbook. I mean, the biggest problem with a turbocharged car is leaning out, because that's when you burn pistons.

You are probably not doing your catalytic converter any favors though.

It wuld make your car inefficient and smell like a gas station all the time.

 

[Sean485]

It may hurt your gas mileage and O2 sensor, but mainly it just runs extremly rich, especially at wot, possibly running so rich as to be letting raw fuel get past the rings into the oil thinning it out and destorying bearings. Not to mention under wot it will be slower than with the smaller injectors because of how rich its running.

Take it to a new performance shop, the one that told you you could upgrade injectors w/o some sort of compensation is either dumb, or trying to get you to spin a bearing so they can charge you to build a new motor...
