These cars are truly dogs. The best mod is to drive it off a cliff, collect the insurance, and buy a Vette.

They are slow, but at least they have dual exhaust.

I have a 98 GT. When I got it, I wasn't really too impressed with it. I started with the small things, like a 70mm throttle body. That didn't do much, but I kept at it. I got a MAC cold air intake and pullies, but I still didn't notice much. Next, came the Magnaflows. They woke the car up. Quite a bit, in performance and in sound. This is where I took my car to the dyno for the first time. Once the pulls were over, the guy asked me what I had done to the car and I told him. He said that the gains were about standard for a non headswap GT, at around 218 HP on the wheels and 287 torque. Figuring a 17% driveline loss that had me at around 260-265 FWHP. I got a king cobra clutch, Steeda Tri-Ax , and Steeda subframe connectors. These were good mods, too. My last mod was a C&L 80mm Mass Air Meter, and this was one of my better mods (I thought). It gave me 8 RWHP peak and 15 ft/lbs or torque at peak as well. HP/TQ=226/302. I have a lot more to do as soon as my finances allow, but it shouldn't be too long from now. I haven't been to the track in a long time, but my best times were 9.71@72.7 mph in the 1/8th mile. There's a few traction issues there.

I ran a 14.20 without the gears and non of the suspension. the best bang for the buck mod is the PI cams. you can get them for around 150-200 dollars. I have seen a thunderbird get 18 rwhp off of them with and automatic. my mods are in my sig.

98n20gt, how did you port your heads yourself?

My car: Dynomax mufflers....that's it.
Stock down to the 2.73 gears. Not for long though. Dyno #'s, no clue. Track times, no clue. Just know what I can and cannot beat in a race.

The car is slow but like all cars, with a little money (or in our case a lot) they can be very fast. Like some other guys said, a head swap really ought to be the first thing on your list. It costs a lot but if you go the other route with lots of small mods, they kinda equal out. Make sure you do it right the first time. See link in sig for pics.

Here's my mods. Best time with drag radials is 13.98 @ 100 on street tires, it's 14.40 @ 98.8. If I could get my 60' time below 2.5, I'm sure it'd look a little nicer.

I dont have to many mods on my car, although i do have a bunch of stuff that needs to be installed (heads, cams, new suspension, gears, etc) but click on the link in my sig for more info. I love my LT headers

My mods are in my sig. I also have a homemade 4" intake tube and a Hurst shifter that are not listed. As far as power, I have no idea. All I know is that I have taken down my share of LS1's and beaten cars that run mid 13's.
