Can you turn a 89 SOHC in to a DOHC?

Can You? and what all does it take? Also, where can i get a powdercoated valve cover for it?

ECU, wiring harness, power steering lines... dunno what else? If you're going to turbo, research the SOHC more. Engine rebuild is inevitable with both, so why not save some cash if you can get pretty close results to a DE?

hmmm......i hope he does not mean just add another cam to the sohc...might be just the way it was asked

but yeah....mr flip said it right

and u can just powder coat it yourself.... u dont need to buy a whole new valve cover,,

wellhung2004, studies show that the majority of males who talk about having a big penis in fact have a very small one.

Just a little bit of info....

studies have also shown that people who go out of their way to point that out are also compensating for said small member

back on topic please.

if you're planning on adding another cam to the KA-E...then buddy, give your head a shake and go do alot of research.

if you're simply planning on putting a DE in your '89-'90 240SX, then it's a simple swap. there's various lines (as mr.flip said) that need chaging on the DE as the locations are different, but other then that, it's a direct bolt in since the chassis was not changed from '90 to '91.

if you're planning to turbo the DE once you get it, then just stick with your E. both are capable of holding boost, and both will need strengthening/rebuilding before-hands anyways.

The dual cam head is larger, probably twice as wide as the single cam(because it has another cam.) Just wont fit.
