'91 cams...again... - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I'm a bit confused as to what part of the '91 camshafts I need to put into my car. I was first under the impression that I needed the entire camshaft (cam gear at end, and the camshaft itself with lobes and all). However, when trying to buy these '91 cams, I was told by the seller that all the camshafts in every DOHC 240sx are the same and the only thing that is different about the '91s are the gears. Do I need to change just the cam gears or the camshafts as well?

I always thought it was the lobes on the camshafts that determined the durration (240/248 on '91s) not the cam gears. Could someone please straighten me out?

Whoever told you that the cams were the same for all the DOHCs is a dumbass, or at least uninformed.

You need the cams. Period.

All the cam gears are identical...so those DO NOT matter.

'91-92 cams are the good ones, 240 intake duration, 248 exhaust duration...as opposed to 232/232 for '94 and all S14s.

Hey, thanks for the input guys. You just confirmed what I thought to be correct. I guess I'll continue searching for some '91 camshafts.

I was actually going to just go to the local you-pull-it junk yard and rip them off the 240 they have there. I know I can get a hell of a deal there. Thanks for the offer though.

"'91-92 cams are the good ones, 240 intake duration, 248 exhaust duration...as opposed to 232/232 for '94 and all S14s."

So what kind do the 1993 s13 have?
