ITB Mustang
I want to build an ITB Mustang. Which year (87-93) and body style (hatch or coupe) is best to start from? Any other pointers and/or suggestions would be greatly appreciated. Also, what size wheels and tires are allowed on an ITB Mustang? I want to buy a car, put the minimum into it to get it on the track, finish up the SCCA schools, and then make it more competitive as I go. I have experience with drag racing V8 Mustangs, but I do not know much about the 2.3. Thanks in advance.

Call autopower or Kirk, get a bolt-in cage, put on some 15x6 wheels with hard compound yokahamas, and go drive. After a while, you'll find ways to spend your moneyOriginally posted by NLPRacing:

79 coupe is the lightest, 93 coupe is the best.

15x6 maximum.

Who makes a better cage, Kirk or Autopower? What kind of brake pads should I use? I found a straight 90 Hatchback with a strong motor (as strong as a stock 2.3 can be) that I can get for next to nothing. Any major draw backs on using this? Thanks for the help.

I have a 79 Mustang shell with a cage in it already, and a bunch of other stuff in it. In fact we ran the car last year in IT, we took some of the stuff off to build a new car. Where are you the car is outside of Atlanta. Call me @770-218-9967.

I couldn't say on who has a better "prebuilt" cage, as I built my own this time around. The Autopower in my old car fit well, but I have no experience with the Kirks.
As to the 90, it's down on power to the 91-93's, heavier than the 79-82's, but everything can be up and back-dated, so if the price is right, go for it.
Ron, what car was that? Got any pictures?

What is the difference between the 90 and the 91-93's that makes them more powerful? Like I said before, I know nothing about these 2.3's. I've owned several 5.0's and 4.6's and know alot more abou them. The car that I found is my Sister's and I can basically have it. What's the best price you have seen for an Autopower cage? Do you anybody that may have a used one?

You know, if the search function didn't suck so bad I's say just look it up.... but...
The 91-93 Mustang received the DPDIS motor, which stands for Dual Plug Distributorless Ignition System. Two plugs per cylinder, crank trigger, and coil pack instead of a distributor. Also, this motor has smaller main journals, and a roller camshaft. The pre-91 cars do not have any of this.
The trick is tuning it properly, as there is a lot less out there than for the older "D-plug" heads. And although in stock trim the D-plug will ouflow the dual plug head, the package as a whole is better in 91-93, which is an advantage in our class. IMHO, of course...
As to the cage, I'm no help. I don't know. We can build you a custom one, but you'd have to bring the car down to FL where we are.

Thank you very much for all the information. I live in Texas, so coming to Florida to get a cage installed would probably not be too practical, but thanks anyway. I did buy my ASedan Capri from a guy near Orlando and towed it back to Arlington, Texas behind a Budget rental truck, though, so you never know. How hard would it be to put the 91 up engine in my 90? Can the timing be advanced on the 90 2.3 engine? As far as the cage goes, for now, I will probably buy either the Kirk or Autopower, whoever's I can find cheaper. Then, put my Kirkey road race seat out of my ASedan car in it and go racing. Thanks again for all the help.

91 swap is not terribly hard, but it is involved. You need to be able to read schematics, swap and cut/paste the harness, and swap the engine. Plus, the 91-93's technology is a bit different, so there's a learning curve involved, but I did it on my old car (#88) with good results. My new car (#93) already has it all, so no swap was needed, but of course the motor is bone stock and high-miles, so this winter it gets a HP bump. (plus trackside laptop engine tuning)
