Did have one I built up. Sold when I got bored with it. Anyway, there are sveral sites that might help. Look under Yahoo. Also try Esslingerracing.com and merkurencyclopedia.com These have some really bad ass cars and some cheap tips and ideas to get more power out of your lil 2.3 .
What year is it? If 85 1/2 or later it has adjustable waste gate. You can adjust it till you get the buzzer on the turbo overboost, then back off 1 turn at a time til you get max boost and no buzzer. Also, get an intercooler from a volvo turbo and place in front of radiator. and hook up. The throttle body cable will need a lil mod to turn it to meet the intercooler outlet pipe. This is a cheap setup without goin into engine. You can also get a K&N Cold air kit for this car. Get it! I would also suggest if you have the money get a superchip or Pwoerprogrammer. They really wake it up. My last suggestion if laws in your area allow it, is to remove the restrictive cat and install at least a 3 in down pipe off turbo and split into duals. This is alot of bang for the buck! You will be looking at approx 255-260 hp at rear wheels with just these bolt ons. If you wanna get into engine, replace the head with Esslinger or Ford motorsport Dport head with oversize valves and roller cam. This should put u at 300 or so. The last thing I did before I sold car was install Ford Motorsport Lightened Flywheel. Idled a little rough, but really ripped on takeoff. Just think, small block power without the weight. These cars really handle well also. I used mine for road racing/autocross. It really had it over the heavier 5.0 crowd. One last thing, if it is an early '84, get rid of the 7.5 traction loc rear. It will blow apart with the extra horses and torque, especially if u get good traction. Upgrade to 8.8 with the quad shock setup. handles better and can take the extra beating at the strip.
