Efrain240Z

Thanks for the replies, guys. I race a Sprite with VARA and have an aversion towards HSR-West. I'm researching what the VARA rules are for a 240z, which would run in VARA's CP3 class. A general consensus is that if it was allowed in the SCCA, its allowed here. Engines cannot be stroked. Everything else is free - how to make 200 hp? I can update brakes as far as 1972 - I know that makes no difference, but ducting and lining materials are free. After market calipers are prohibited. Suspension - no coilovers and must use stock attatchment points. Everything else is free. So a target is 200hp, and 2000lbs. The only shortcoming is the brakes at that point. My uncle gave me his 71 240z for my 16th birthday. I've had too many other car-related activities going on to do anything with it yet (3 years now). Its a rust free car that had its hydraulics go to hell so he parked it. It seems a shame to rip it up to make it a race car, so an ITS 240z seems like a good way starting point. This isn't an imminent decision. Its research. But I am starting to like the idea of a 240z vintage racer...

In the vintage club that I race, 911s generally rule the CP class. I am curious to see if a 240z could be built to run with these cars. An early 911 can weigh as little as 2000 lbs, have about 200 hp at the wheels, and uses ventilated 11 inch brakes. Long wheelbase 911s weight slightly more, can have up to 2.7 liter engines, and uses the same brakes. So, how much can a 240z reliably put out, and how low can you get the weight? What do the 1972 SCCA GCRs say about allowable modifications to the brakes?
