You might have seen this in the 240sx tech forum but nobody answered so here it is. I've got a SOHC hatch that I want to swap a fresh rebuilt DE. I'm not planning on going turbo yet and was just looking at a tune and bolt-ons. My question is, does this tune give substantial enough power to justify the cost of it? If it's less than 10-15, I say no just wait for the turbo kit. If it's over 15 maybe. Btw, I'll slowly be putting bolt-ons on it every so often until I save up enough $ for KA-T.

no, the cost and performance gain of staying NA, tuning, and buying the parts aren't worth it.

keep it stock. save up till you have enough. then turbo it right.

with the 400$-500$ you spend getting an intake, header, tune, and exhuast installed , you couldve started piecing together a turbo kit.

i was able to get a ka-t kit (with fmic, sr injectors, sr t25, piping, bov) together for roughly 650$ for shipping.

also, when you go turbo, youll be ditching the headers and intake anyway, and will need a new tune, unless you run a low boost setup, which you can get away with a FMU.

hopefully that gives you an idea.

next time search
