I searched for what the HP was on the NA first gen Mr2s, and couldn't find a thing. But i did find that the s/c engines had 145 HP, so i would imagine that his car has quite a bit less than 120-130 HP. Considering that your car has 190 horses, i think that you will slotter him!!! Even though his car is ~300-400 lighter, you should still win. Good luck
