An E or e.t.a is not in any way comparible to an I motor E30. Its like comparing an HX CRX to an Si or a V6 stang to a V8. I had an E30 4 door, intake/exhaust/chip blah blah. It would run low 15's with full interior. I have no doubt it would hang but most likely get beat pretty bad in a straight line. I ran a V6 exhaust camro from 60 once and I pulled 2-3 cars by 100 to give you an idea. I'm not even going to talk turns as they are legendary track cars, autocross cars, 1st time learning cars etc.
