Ahh, I checked and we're both right. 1991 version was a 3.0 V6 with a 5 speed with 220 horsepower. There was a second gen car from '92 to '95. And auto version of that car had a 3.2 V6. Starting in 1996, the SHO had was a 3.4 liter V8, again built by Yamaha, with 235 horsepower and an auto slushbox. Production ended in 1999. V6 version was faster
