Fox MODS question

If you're running stock heads, save your money on MAF. The stock E7's can't support enough airflow to make any appreciable horsepower (without a turbo or blower), thus there's not a lot of sense in trying to open up anything in front of the cylinder heads since they are mostly the bottleneck.

When you save your pennies for a set of aftermarket heads, cam, intakes, THEN you can worry with the MAF, tubing, and ECU stuff. When that time comes, you can go with a quarterhorse, 80lb Siemens deka injectors, and tune it yourself. 80's seem like a LOT (and they are) but they will usually work well at very low pulsewidth (good idle and low RPM manners), yet give you PLENTY of room to grow if that need arises. You might even be able to sell your current ECU and MAF to someone who needs them for their Cobra, and use that toward your mods. Reason I mention the quarterhorse is because you NEED to tune, even a stock engine could benefit from tuning it. The stock A9L's maximum ignition timing is 26 degrees, which is real conservative. One might pick up some power just in increasing the timing to 34 or so, might see 20hp or so. No, just advancing the distributor won't help and stands to make it worse in other areas such as part throttle cruise.

I've got a '93 GT that is bone stock, and I plan on leaving it that way. It's got enough to get me around ok, it is slow, it's sluggish, but it's one of the VERY few stock GT's around that I know of. Most of them are modded heavily. Also have a '92 GT with a 427w and a '92 coupe 4 cylinder. Honestly? I drive the coupe everywhere...daily and then some...I like it better than either of the GT's.

one issue with the gt40P heads is the headers. If you don't have headers that fit them then your cheaper off with the regulator gt40 heads.
