I am considering buying a caged 1st gen shell with a logbook to either put back to IT7 or ITA in SCCA club racing, I'm trying to decide if it's worth it cost wise or to do something else, I know buying a race ready car is always easier, but I don't want to miss out on this if it can be done cheap.

I put together a list of what I think I need, I still need to go see the car and he said he will throw in as much as he can. This list does not really include a legitimate engine build as I don't know how much to expect or what condition an engine I'd be getting would be in, I do know the seller is a huge rotary guy though and said he can help with a build.

Race car: $350.00
Donor Car: $500-$800

Parts

Race suspension: $400 (Mazdaspeed IT kit $1098)
Upper strut mount: $100.00 (fronts) rears?

Rear links: $370.00
Watts links plus competition mount: $160.00
Clutch: $200.00
Brake pads: $147.00 - $230.00
Brake rotors: $80.00

Misc. $300.00

I got these prices primarily from Racing Beat, Mazdatrix, or RockAuto. I don't know RX-7 suspension that well but I'd assume a donor car wouldn't be mint and driving so I would assume most of the suspension needs to be replaced unless the suspension on the race car (it's currently a shell/slight roller I'm told) has good suspension.

Any input is greatly appreciated.

 

sterlingmetalworks.com (pretty sure that's the correct url, might want to google it) gives you a breakdown on how to modify the stock nikki carbs to increase power and make it more reliable. I'll have to hunt down another member here, he does a lot of scca events in southern michigan in his fb so would be able to give you more advice
