I have a 91 GSX stock internals with GT28 .45A/R, FMIC 2.5" TURBO BACK EXHAUST, with a ported exhuast mani and EVO III O2 Housing.

i want to get the most out of my turbo.

what supporting mods should i go with?

Injectors? Fuel Pump? GM MAF?

Depends on your long-term goals and if you mean you intend to just max that turbo or someday go higher. Either way, follow the Upgrade Path list of mods under the Tech link up top of the page. Also depends on how much you are willing to spend. If you want to max the T28 then you can follow my upgrade list for bolt-ons and engine, adjusting it for a manual transmission. It doesn't take much to max that turbo. I'm currently at the point I need to go to a 50 trim in order to grow into my mods.

And you are asking about a MAFT but your mod list shows it already on the car, not on the wishlist.

But first thing you need now is fuel to go with that airflow, and air/fuel management of some kind to go with the fuel mods.

Two good options:

1. Walbro 190 pump, 550s, pocketlogger, safc
2. Walbro 255, AFPR, 650s, DSMlink

Second option is better all around if you have the money, need better tuning, and want to go bigger someday.

Plenty of people have reached over 400 whp with stock 2G MAS. I think when I get to that point I'll do the MAF/T, but as of now there are much better ways to spend $500...like a 50 trim!!

See my above post on fuel delivery...depends on what you want and what you can spend.
