so, isnt a 325 (no letters) super eta? am i right now?
No, the 84-87 325e is a 2.7l M20 with 121hp, 170lbft and a redline of 4900, with motronic 1, not carberated. The only carbed engines in the e30 were the 316, 318 in europe with the m10. the 88 325 (aka super eta) is still a 2.7l, although it shares more parts with the 325i, it also has the more advanced motronic. If you can only afford an eta, look for the 88, as you can swap the head from the 325i on to make a 2.7i stroker.
However, the best choices in e30s are the 325i/is/ic/ix or the 318is. The 325i has good power (168hp, 164lbft) stock and revs to 6900. With a 4.10LSD it hauls ass. The 318is with the m42, is not as powerful, but it is much lighter. For a track car the 318is is better balanced.
I think it is best to look for a later model 325is/318is as they look the best and are the fastest for the price. My convertible is soon to have a bit of a makeover, with the late model bumper swap and a full repaint, as well as chip and cams and a 5 speed swap and a 4.10lsd. However, it is still a fuin car to drive as it is right now.
to sum up:
go for the 325is or the 318is
oh and also e30tech.com has tons of info on tuning and maintenance.
