Thanks for the mention of my article.
FWIW, KA24E's never came with carbs in the US, only a downdraft throttle body (truck), and multi-port EFI (89-91 240SX). They may have had them in other markets, though?
Yes, hooking up the EFI for a KA is pretty simple. For the best in output and relative ease, I'd suggest what I'm doing with mine. I'm installing a Z20E with EFI. Then later on when it's no longer enough power (it never is
), I'm going to add a turbo. Or you could just start with a Z18ET (destroked Z20 with a factory turbo). I think the factory turbo will hit the LHD steering box, though. A Z20E is less weight than a KA24E, and they are just as plentiful and CHEAPER.
This swap uses all US-spec parts and is pretty simple. Tim's done one already and we are doing another to "Gil" as we speak. Then mine will come together later this year.
