I am getting the itch to sell the race car project again. So, I'll borrow some stuff from my last ad, update it with new extras and lower the price. If it doesn't sell, I probably don't care. If it does, great. I'm getting the itch for a Corvette, or who knows what, but change is good right?

All carpet, door panels, etc has been removed. The AC and heater assembly has been removed and the holes in the firewall are patched and sealed with RTV. There are two front seats in the car. The factory dash is in place as is the factory instrument cluster. The doors have been gutted and it has no side windows. The rear hatch latch has been removed and hood pins have been installed to keep the hatch closed. The doors have been gutted to prep for the roll cage (no windows). This car does have headlights, tail lights and turn signals, but the horn has been removed (just fyi).


Suspension:

Hotpart castor/camber plates
ST 35mm front bar
Koni SA’s

Hotpart swedged chromoly rod ended PHB
Hotpart aluminum rod ended LCA’s
Koni SA’s (30 series monotube)
Hellwig 3 position adjustable rear sway bar 22mm (other bars on request)
Ground control weight jacks with 225 in lb springs


Brakes:

Ed Miller C4HD setup on front with Hawk HP+ pads
Factory 1992 disk rear with Hawk HPS pads
ATE superblue brake fluid


Wheels:

A full set of polished factory IROC 16x8’s and two "rear" GTA wheels as well as an additional set of 4 IROC wheels with Toyo Proxes on them (pretty dead ones, but I'd run them for fun).

Car needs redyno’d, but it is approximately 330-350 RWHP (it was dyno’d on a dyno that was reading very wrong, my max rpm was showing as 5,600 and we ran to the 6,400 rpm shift light. That dyno showed 299 hp/ 338 ft lbs, some exhaust changes were made and it picked up considerable power, so, that’s where the 330-350 hp guess is coming from (fix the 800 rpm they “lost” in the calculations and add a touch for the new traction problems after the exhaust). Car is approximately 2,800 lbs. This engine was built to be durable (hence the splayed caps, main studs, balancing, etc). It makes good (actually it’s about perfect for American Iron once it’s caged) hp and torque, but it’s not a 700 hp monster. It is still pretty quick due to the power it makes and the weight (or lack of weight).


Tuning:

I’ve got the moats “Osterich” setup for this car. I also have a prom burner and cables to do datalogging.

As you can see, there is a "fortune" in this car. I'm guessing between Mike and I (the last owner), it's something approaching $20-25k. Of course you never get that out of them, but go find a factory 1992 hardtop chassis (the "best" year for 3rd gen chassis since they were welded and bonded together) and start pricing parts. I think you'll find this to be a pretty good deal on a fairly well sorted car. It's been pretty quick out of the box (beating some slick tired cars in CP while running on street rubber...and I'm not sure how, it's not my driving). Someone cage this thing and take it AI racing.

Speaking of caging it. I have a fresh roll cage kit from Blaine fabrication. It's a full cage kit with a petty bar, an inverted V in the rear to support it and dual nascar style door bars (for both sides). I've got over $1,000 invested in cage parts...plus freight.

This car should come out just about perfect for American Iron road racing when it's done.

$8,250
