I am about to purchase a 95 GT 5 speed. The motor has GT40 heads/upper/lower intake, B303 cam. 70mm throttle body, longtubes to flowmasters, EGR delete, Trickflow cai, and underdrive pullies. But due to the guy selling a few things to his friend. The car has a stock maf, ecu, and stock injectors. What maf, ecu, and injectors should I go with? Also, what kind of whp increase will I see from adding these mods? What would you say its putting down now? Will the car be too lean without #24's? I used the search and couldn't find much on the topic.

The car will run fine with the stock injectors and maf. Its not making enough power to justify the swap to 24s. At most with the gt40 stuff its at 250 HP.

What would I gain from injectors, bigger maf, and a tune?

dawson1112

No gains at all. Your not going to gain any more from larger injectors, because the engine can not use the extra fuel with out better heads and a better intake. The maf is only there to tell the computer how much fuel is needed, and the heads and intake limit you on how much air can be drawn in. Your money would be better spent on changing rear gears to a 3.73 or 4.10 set.

What about a tune? It keeps throwing a cel because of the egr delete

The egr code can be turned off with a tune, but its a little pricey to just turn off the egr. If your not getting any lean/rich codes then your ecu is doing its job. And other than adjusting your timing advance a tune isn't going to net you any more power. You can adjust your timing advance manually at the distributor and get the same effect a tune would get you.

Again I say spend your money on gears, it will make a significant difference , and one that you will feel instantly once completed.

Thanks. Is there any other way I can get it to stop throwing the egr code? resistors?
