1992 Ford Mustang LX 5.0
Started on May 4 by robench
My 2002 Tii is still a few years from being roadworthy and I was getting the itch to get back on the track. I found a deal on a Mustang that was far less than the price of the performance parts already installed and bought it on a lark. I flew to Texas with some spare parts/tools and drove it home to Seattle via the Southwest. Boy, there is a lot of desert in this country.
Since then I've completely gone through the suspension, interior and engine. It's been a lot of fun working on it, and it's payed off with a nice track car that is pretty fast and well sorted. I don't have too much into it (not counting all the labor) but It's a bit faster on track than an E46 M3, so it's pretty good bang for the buck. See below for the long list of modifications. I'm an engineer by training and it's an interesting challenge to get a nose heavy sedan with bad suspension and small fenderwells to handle well.
I use it for open track days, autocrossing, and even a little drag racing. It's a rough, noisy, god-awful road car, but it's comfortable enough to drive it to the track.
The engine has a freshened stock bottom end with a reasonably well matched set of top-end parts. It should be good for about 360HP. A lot of the engine mods were already in place when I got the car, saving me a lot of money.

The front suspension has extended lower ball joints to keep the front roll center height reasonable despite being lowered. It also has a bump-steer kit to keep it pointed in the right direction.
The rear suspension has a panhard bar for lateral location and roll center control, relocated lower control arms for additional anti-squat, and adjustable spring perches for setting corner weights.

- Maximum Motorsports adjustable rear sway bar.
- Modify the front K-frame to relocate the inner end of the control arms.
- Coil over kit for the front.
- Brake cooling ducts.
- Megasquirt or Tweecer for ECU tuning
- 347 bottom end for the engine.
