All I can contribute is that it should be a curved neck.
yeah thats what I was worried about, hes not in the least mechanically inclined, or able to pay somebody to do it, and I dont have the time or the care to do the swap myself. hmm....unfortunatly the mx3's did not come with a klde, they came with the k8(1.8l v6). but that said the swap from a 6cyl mx3 to a klze can be done fairly easily but you will need a complete uncut wiring harness and ecu from the klze. now the swap that I am doing is more difficult in going from the 4cyl to the klze, that involves new mounts and a host of other things, I am actually thinking of getting a MX6 or MX3 v6 donor car to used for parts for the swap if I can ever get the time to put it in the garage and work on it.
Send him to MX-3.com and he can find a lot of good information there on the swap....
