S12 200sx engine advice

wow james, you are quite the dreamer!

to twin charge these motors, you need to find a supercharger for them. as far i know, there are no superchargers that bolt onto any of those motors. so it would all be custom.

I only know of 2 supercharged SR’s and they suffer from crushed bearings because the motor wasnt designed to handle low RPM boost. you would likely run into the same problem. more-so the CA then the KA.

twin turboing a 4 cylinder is stupid. there wouldnt be enough exhaust energy to spool 2 decent sized turbos. the drag caused by 2 turbos as apposed to 1 is another factor that would deminish any of your gains. there would also be a lot of piping.

if you want to avoid lag, build a KA24, and bolt on a garret GT28RS. it would be a lot cheaper then your ideas with much better results.

or you could try and fit a VQ.

just speculating. I have no experience with nissan motors, so yeah, going on advice others give me. (i’ve seen supercharged rotaries, and they’re bad ass)

as for VQ, bleh, never been a fan of V6 or V8 engines.
I’ll let Dennis have the final word, since he’s doing the swap, but it’ll probably be a KA or his RB20, since the dam thing is lying around anyways.
