My friend hasa 1993 ZX7 and he is thinking that he wants to take the motor out and do some serious work to it (bored out, headwork, etc.) I was kinda wondering if some of you guys have swapped out your engines for any other engines (i.e. ZX-9, etc). The ZX7 is a bit.... thick to say the least so I think it could support a bigger motor. Appreciate any input anybody would have on this!

 

a little work and could probably drop in a new 10 motor

 

This is a good read. http://homepage.ntlworld.com/webzxr/...res/tuned.html

Also heard that you need to use the zx7 headers to make it fit right because of the radiator. I have not tried this project so really do not have any answers to help out.

 

Good info, appreciate it.
