1993 Touring, Track/AutoX Toy

I purchased this car from a local motivated seller in bone stock condition. It came with a recently rebuilt motor from Peter Farrell Supercars, two sets of wheels and a catback exhaust as part of the purchase price. I was in the market for a Miata at the time, but this came along locally and considering the amount of work recently performed for the asking price, I couldn't pass it up.

The setup has evolved by identifying weaknesses at track days and fixing them. The biggest issue with the stock configuration was inadequate cooling (water, oil and intake charge). The car has been set up to be more reliable at the track with greater cooling capacities while still running stock boost levels.

As of summer '09, the car has seen over 40 track days (still on original suspension, power levels, etc.) Towards the end of the season I noticed it starting to drink a small amount of coolant which translates to the beginning of a seal failure.

Over winter '09-'10 I replaced the motor with a slightly upgraded unit, all new coolant hoses, fuel components, clutch, pilot bearing, seals, etc. I still plan to run stock boost levels on the stock sequentials for now, but the new motor is built for a large single turbo.

My long-term plans are for continuing to improve my skills as a driver in HPDE events without relying heavily on performance upgrades and just enjoy the car the way it was meant to be used.

Nice FD! Love the well-detailed spec list. Good luck with the bodywork! I have an FB (check out the Reader's Rides, it's the Red GSL) and it needs the front re-done (looks like they slid it into a trailer hitch right at the headlight) so I'm in the same boat (as far as following the Saab articles). Keep us updated!
