There are several on BaT most of the time. Do not buy a Turbo. The higher performance (that you may not be able to use) does not outweigh the problems with this version.
I owned a performance tuned TI, a TII for a short time and a Turbo together with the TI. The exhaust header on the Turbo disintegrated and fell off 3 times during the 2 years I owned the car. My favorite was the TI with 45 Webers instead of the stock 40 Solex, vented disc brakes in the front and flared fenders with 7" ATS wheels. The car had a Schnitzer-prepped head and made 160hp, only 10 short of the nominal 170 of the Turbo. But it had a so much better driveability with no Turbo lag out of lower RPMs. The 02 was one of my favorite cars I owned
