hey, i know this is probably a total noob question, i have looked around a bit but probably not hard enough. how hard is it to swap a ka24de engine into a 620? how much power do they make, and is it expensive to extract more power from them? is there a step by step posted anywhere on ratsun? thanks in advance:)

About 75% hard if keeping the EFI setup, maybe half that if running a carb. You will need a KA tranny. They make around 150 hp. You can spend as much as you like to make more power. Equipment is plentiful for the KA and builds are well documented. No step by step on ratsun that I know of... but I didn't check the FAQ or search either so I could be wrong.
