A KA24DE swap into a KA24E 240sx is just a matter of getting the DOHC wiring harness from what I remember. My plans for the 89 were to build a motor for it anyways so having to purchase a ka24de wiring harness wasn't a big issue. But before I could purchase a spare KA24DE and start building I ran across one very nice red 95 Z28 6speed 
do you have any idea how much a ka24de costs and/or where i can get it? i have a 90, with the sohc and was planning on getting the ka24de in the near future. i was planning on doing all the research and stuff when i actually have the money and stuff, but if you know off the top of your head, it might be good to know how much i should aim for.
