Four models were made. The base, ES, RT, RT/TT.
Base came with the 6G72 SOHC 3.0 V6. The ES and RT came with a 222hp 6G72 DOHC 3.0 V6. The RT/TT came with the same 6G72 DOHC with twin turbos putting out 302hp 91-93 and 320hp 94-96.They never became as popular as the Supra, skyline, and other japanese supercars because they are the heaviest of the group with the top of the line TT models weighing in @ just under 5000lbs. I had a base model that after I got doen with it weighed in just under 3000lbs. The TT model recieved most of its weight from the addition of AWD, AWS, and active aero. (edit this text)
