Remanufactured or Rebuild

Since the ZX motors were in the neighborhood of 180 hp (gross) you are already ahead of an L24 by about 40 hp. As far as what you end up with there is no way to tell. Do your research, and put it together the way you want it or with what you can afford at the time. There are too many variables to consider such as compression ratio (depending on which head you choose) the intake you use, the cam, ignition, well you get the picture.

Take your time and you will get out of it whatever you want. Is 200hp out of the question? Probably not due to the displacement advantage. Like I said before, go to the Z garage web-site and do your homework before you start buying the parts.

Another good way to put some zip into it would be to find a 3:54 ratio rear end out of an automatic car. You should be able to pick one of them up pretty cheap, possibly even at a junkyard. It won't make a huge difference but it will be one you can definately feel.
