Default Autox classification for a j-spec

Any idea what class a j-spec would fall in? The car is originally a '94 Impreza L 5 speed sedan.

Now it's a '95 WRX, ie, turbocharged ('95 WRX's had biggest turbos of all j-specs), intercooled, 17" rims, Eibach prokit (lowering springs), KYB AGX shocks, STi engine/tranny mounts, BOV, turbo timer, ACT clutch, WRX brakes, 3" exhaust.

Does this put me in "Prepared Class C?" http://www.scca.org/amateur/solo2/classes/index.html

Unfortunately, I don't think CP is right. I think you end up in E Modified. Since your car isn't listed in the CP list, I don't think its eligible. And the type of modification you've done is (I think) outside the scope of Prepared class rules.

15.10.D.1 - Turbocharging and Supercharging is prohibited except for specific vehicles as listed in Appendix A.

Since your Subaru is listed as a NOC (not otherwise classified) in Appendix A, a turbo is not allowed (if not stock) and your car couldn't run a national event (in E Prepared) even without the turbo (car has to be specifically classed to run nationally in Prepared - NOC doesn't count.) You could run it in A Prepared, but not with the turbo.

However, you are definitely legal in E Modified. We had a ProRally car (Impreza L now running a 2.2L turbo charged engine) run an event in E Modified. Unfortunately, E Mod is a class that is way out of our league. A fully prepped WRC car (tarmac settings) is probably competitive. But why would you bother?

Edit: Oh yeah, almost forgot. It sounds like you have a kick a.... errr.... a great Street Mod car. You'd be much more competitive in Street Mod and the engine rule is just the same manufacturer (Subaru!) and have the car be street legal.

Steve is correct, you can run that car in SM. It is materially the same as our domestic Impreza chassis, and next year the "legally registered" part of SM is said to be going away.

This is what drives me nuts about SCCA autocross rules. They are designed for people who read the rulebooks upside down and backwards looking for loopholes, without any consideration for the actual performance of the car in question.

When my Alltrac was undergoing the slow and painful transition from street car to rally car, I autocrossed it a couple of times. Sure enough, I was put in Modified where, after a few classes were consolidated, I found myself running against an F440! A perfect match for my 3200 lb Celica. I think I had enough ground clearance to run over most Modified cars without touching. This was in the days before the new classes, of course.

Heaven forbid you show up with anything innovative or out of the ordinary--you'll be classed with F1 cars and they'll probably protest you, too!

Yes, the SCCA's Solo2 rules show obvious signs of dating and rules creep over their >25 year history.

They need a major overhaul, maybe that will start in the stock class. Maybe most people are happy even if some are stranded between classes. Your Celica is probably still illegal for SM Jon, assuming it has interior trim pieces removed (like doorskins) or a cage that ties into the front struts through the firewall.

That's technically illegal at least. If you wanted to run it I wouldn't care.
