Hey,

I'm currently searching (and did this for quite a while) for a complete turbo kit for a 1989 240SX (which has an KA24E afaik) but found nothing.

Only for the KA24DE - but doesn't the "D" only means "direct injection"?

Is it possible to turbocharge a 1989 240SX?

D = Dual Cam

I've never heard of anyone turboing that motor, but im not a KA guy so idk maybe they do it. You can get a decent dual cam KA though for cheap money.

sure it can be turbod but the DOHC is a better motor to turbo imo

There are actually quite a few people who have turboed that engine with good results. You are better off piecing together your own kit. http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=33632&item=7923391387
That is a good place to start. Compression test first. A good sized T3 can work very well.

yes it's very possible to turbo it, the power numbers aren't far off from a DE, so that is nothing to worry about.

i imagine you could use any DE kit minus the turbo manifold, and just get the mani off ebay or something, they pop up every now and then. (not 100% sure on needing just a different manifold)

one place that i do know that makes a turbo kit for both DE and E is www.import-autoperformance.com

just shoot em an email with questions and they'll happily respond.

hm, seems that turbocharging a S13 240SX is more expensive than buying an euro S13 200SX with the CA18.
The car would be like 600€, plus 550€ for a manifold, maybe 400-600€ for a turbo and I don't know how much for other parts - would be more than buying a S13 200SX + rebuilt + bolt-ons... :(
