Ok, a poll to help a brotha out.

regarding 240: ka24 vs. sr20 is a horrible comparison. there is no way that you could build a ka to handle the output of a mildly modded det regardless of form. even the de version of the sr20 would murder the ka. it's a truck motor put into a freakin sports car, it has no top end, it has no bottom end, a big accomplishment with that motor is getting it to lay down 200whp n/a. you can turbo it but with only minimal boost before it goes to shit. sorry but swapping out the ka is a necessity. as for putting in an rb, well it's been done quite a bit, throws the weight off a little. might as well go rb26 for the twin turbo if your going to go with an rb series. not any bigger or heavier and has unlimited potential. just whatever you do don't even think about a vg30 swap, motor is horseshit.
