Um... KA? Heh, sorry man, wrong forum. Anyway, I'm pretty sure people have had a lot of success with all sorts of swaps, including what I think you're trying to do, OBD1 engine into OBD2 car. Personally, I'm a fan of the KA-T, but that's just cause it's a little more absurd/less common... one day I'll get a 240 and do the little crazy KA project I have... mwahahaha...
Mods, he'd probably get more help in the 240SX area
