My '97 900 SE Turbo, 5 speed coupe. Picked it up in October '06 for $4k, started modding, and two transmissions and many speeding tickets later here we are. Tuned to SQR stage III for a little while, then replaced the Garrett T25 turbo with a Mitsubishi turbo from an '02 SAAB 9-5 Aero, and had it re-tuned to stage IV. Then had the T25 built into a "big" t28 by GPopShop and had the car tuned to stage V.
