Cavalier/Sunfire in my rear view
I've got an '02 P5 in automatic and the other day, I raced a cavalier and a sunfire from light to light, but it was a pretty long distance. If you're wondering, I was near a GM dealership.
Anyhow, my car is automatic and theirs were manual. I went through the gears in auto and blew them away. I had a good 1.5 car lead off the line.
Rememer, they might have 140 HP, but they also have several tons of weight and bad throttle response.
With an older Z24 with 150HP, you'll have problems though. Just do intake and full exhaust and you're talking about 15-20HP gain, so you'll be able to blow away almost any of the newer compact cars.
that's IMO
