Yes, I did some in the past in the MR2 world and still love those cars. I have had about 8 different ones in the past. The main one I had was 91 MR2 turbo and went to the Sport Compact Car USCC a few years ago. I had the car to far on the ragged edge with 525+rwhp and 10,000rpm so it went pop a few times to many, but it was so sick and fun when it ran. Of all the 8 MR2's the most fun was my 85 hardtop with a swapped 88SC engine, smaller pulley and sticky kumho tires on spyder rims. It weighted in around 2300-2400lbs and made about 150rwhp.
I did learn one major lesson from all of that and that is reliability. I have a rule now "I need to be able to drive it to work everyday and not worry about my car or it is nto for me". I live by that for my mods I do and will do.
