I've had the '92 GT 5-speed for about a month now and I'm looking for some simple bolt-on mods that will not significantly decrease gas mileage (so gears are out of the question).

This is not gonna make a big difference, but I'll be getting an Aluminum driveshaft within a week or 2. The car has 167K miles on it, but was VERY well taken care of. It is totally stock except for Flowmasters (2 chambers). I was thinking about a rebuild, which would probably be best b4 modding it, but what would I be looking at for that? $800?

What do you think about these mods (considering gas mileage and streetability--- This is my everyday driver car and sees a slightly above average amount of highway miles).

1) Heads (which ones -- AFR 165s, TFS?
2) Cam (to match the heads)
3) Intake (TFS)
4) Headers (MAC)
5) High flow cats
6) MSD Ignition, distributor and coil.

I would like to set it up that later I could add a little boost to it, say from an intercooled Procharger blower at relatively low boost, ~6-9 lbs.

Let's say I'm looking for a 13.1 to 12.9 sec car in 1/4 (without the blower), with relatively good gas mileage and durability.

Oh yeah, and how do these 5-speed trannies hold up? Last night I was accelerating on the highway to about 100 mph in 4th and felt the stick shaking a bit more than I expected. Is that normal/common? How strong are the stock 5-speeds? I know they gotta be a bit better than the AODs.

I know those are a lot of questions, but answer whichever you can. This is the first time I've owned a 5-speed Mustang 5.0. My experience is mostly with my 351W-powered '79 backed by a C4, running low 13s. So you see the contrast in setup. Thanks.
