Cheap performance upgrades for a GT?

I was curious if there are any cheap performance upgrades for small increases in horsepower for the GTs? Ive cleaned out the intake, throttlebody, etc. but i was wondering if anyone knows of any other ways to increase a few horses.

gears are the best thing to start with, no increase in hp but best mod for the money

500 for parts and labor typically. It's not "cheap" but it's certainly more cheap than any real performance upgrade. Alternatively, a good tune costs about the same and can wake up the car as well. I got a dyno tune and went from 215whp to 241. One of the better $500 performance upgrades.

You may already have an aftermarket cold air intake. But to get the same results (a couple of horsepower), you can take off the silencer and put on a K&N filter. This will save you in the long run as well because you won't have to buy any more air filters.

Depending on where you live, the next most inexpensive mod is an off-road mid-pipe (illegal in all 50 states but a lot of states do not have inspections). You will need to run mil-eliminators to trick your ECU into thinking the rear O2 sensors are reporting the correct data. This mod is not suitable for all people.

Gears may or may not be considered inexpensive. Depending on where you live it will be $400-600 installed and they will most likely lower your gas mileage a little. They also make your speedometer off so you will need a handheld tuner or a speedcalc to correct it.

A handheld tuner tuner is a good investment. It allows you to load a 93 octane tune as well as correct for gears and tire sizes. It also allows you to turn off the rear 02 sensors.

Had I done my research on how expensive it is to even get 10rwhp out of these cars, I may have started with a different platform. I love my car, the look, the sound, all of it, but it is so expensive to get any real power gains. You're basically restricted to FI to see any big difference and that isn't cheap.

Gears definitely gave me the biggest seat of the pants increase and didn't hurt my MPGs at all. But the CAI, mid-pipe, catback, TB and plenum that I have done maybe gave me 10-12 HP total combined. The exhaust was mainly chosen for sound. The TB and plenum helped with throttle response. CAI was basically for the look and it did make the car sound a little deeper.

If you're wanting big power gains then take this as solid advice. Throw some exhaust on that sounds the way you want it. A mustang shouldn't be quiet. Throw gears at it for a to temporarily satisfy your speed need. Then just save and save for either F.I., No2 or heads/cams. Don't waste money on the small things like I've done.

Suspension is a good way to liven up the car, same with a good set of tires, but that's not what the OP asked for. He asked about HP. Gears don't add horsepower either, but they at least give the illusion of adding HP.

not sure what you consider cheap? but the o/rxpipe is the best and CHEAPEST bolt on imo. I only paid a 150 If I remember correctly for it brand new from UPR

thanks for all of the responses.. im looking at throwing 1k or under in the car to make it a bit faster (horsepower or gears) I think ill go ahead and start out with throwing the 4:10 gears in and maybe headers.. any recommendations on where to shop for the 4:10 gears?

you would be a lot better off with an off road h or x pipe rather than headers if your on a budget. headers arent going to do much unless you get long tubes then u would need a different mid pipe anyways

+1

Headers aren't worth the time, hassle, or money until your pushing a good amount over stock power levels.

If you are going to do gears first then get a handheld tuner. A 93 octane tune will get you more than headers. Headers are expensive, hard to install, and they will get you maybe 5-7 rwhp.

If its a stick, a short throw shifter will make it a little more fun and sporty to drive, and faster shifts.
