they are rated at 300HP at the flywheel, which means his car is pretty much stock, and a little worn. though they are still beautiful cars.
After reviewing about 10 sites, I found there was 10 different numbers for the wieght of an mr2. The highest being 2,780lbs. which is still 694pounds lighter than the Z.
