to4E turbo supporting mods and power??

[RockStaRGs-T]

Iv got a 95 gst that is bone stock right now. Waiting to be installed is a FPR, 3" down pipe with a full turbo bakc exhaust. 550cc injectos, FMIC, and k+N drop in filter.The guy it off of gave me a turbo that is a t04e A/R .50. No shaft play watso ever. My question is what am i looking to gain if anything at all with teh turbo and should i use the injectors with it??? is there anything else i should od upon installation

You can't just bolt a 50 trim (if that's what it is) on your car with no additonal mods.

Say, for instance, you were running 14psi on your stock T25. You then decide you're going to bolt this 50 trim on in place of the T25. The boost level you'd have to run to safely not overrun your fuel system would be around 8psi. At just 8psi, the 50 trim is going to feel much slower than the T25 at 14psi because you're well below the compressor efficiency of the turbo AND it will take longer to spool to reach 8psi.

You have a lot to learn about tuning and alot of modding to do before you're ready for that large of a turbocharger:

- Why an aftermarket FPR if you're using the stock pump?
- You have 550 injectors, what do you plan on tuning them with? You can't just throw them in your car.

You see what I'm getting at.

Yup. You're absolutely correct.

To the OP: You could bolt up the turbo and run 8 psi on a stock fuel system but the car would be slower like jusmx141 said.

The FIRST thing you should do is ALL your basic maintenance and repairs.

Then if you want to make more power then the 550's and a rewired fuel pump along with something to tune the injectors with like a SAFC with a wideband O2 setup is what you need. That should give you some zip.

If you plan to make big numbers then you might want something more advance like DSMlink instead of the SAFC. For big numbers you will also need bigger injectors and a aftermarket pump.

If you want to start smaller then you need a SAFC (or something akin to it), fuel pump rewire kit, MBC, a boost gauge and a wide band kit (Zeitronix is a good all around setup).

The 550cc @ 80% IDC will support 31.58lbs/min and a rewired stock 2G pump can easily support that. Well tuned, 31.58lbs/min will put you at 250-280whp which is plenty. Taken from this thread: http://www.dsmtuners.com/forums/tuning-engine-management/244522-injectors-fuel-pumps.html

I suggest you do your research before bolting up that turbo or else you'll destroy your car. Here are some great links to get you started: Tech Guide - DSMtuners Tech Article Archives - DSM Forums http://www.dsmtuners.com/forums/search.php

Good luck,

Tom

EDIT: You'll also want a 1G BOV or better.

i Forgot to add that i am getting a walboro 255 fuel pump. IM to slow the sppol by getting the bigger turbo because right now my car spools at like 2,500 but falls on its ass a 5k. I just want somthing to hit harder but higher in the RPM range

With a 255 you'll need a adjustable FPR. But for the 550's you don't need a 255, a rewired stock pump is all you need.
