Is the engine really that much of a difference. I know the 89-90 have the KA24E and the 91+ have KA24DE. Well, my question is, is there really that big of a difference between cars. I plan on getting one as a daily driver. And maybe a little bit of mods here and there. I looked thru the classifields and 89-90 240sx are all over the price, and a lot cheaper then the later models.
Thanks

from 91 to 93 they had the KA24DE which is a dual over head cam engine (DOHC). Which means it has one cam for the intake, and one for exhaust so you can control the timing of each differently. The 89-90 models had the KA24E, which is a single over head cam engine. This engines one camshaft controls the intake and exhaust.

KA-engine
24- means its 2.4L
D- dual overhead cam
E- Electronicly fuel injected

KA-engine
24- means its 2.4L
(no d for dual over head cam, so its single cam.
E- Electronicly fuel injected

I thought the E was for Engine. :-P

ka24de=155hp ka24e=145hp

does the extra 10hp make THAT much of a difference, or is it just something good to have?

they both are ok...

if your going to run a turbo id run the DOHC though, because the SOHC spark plugs and wires go into the side of the block in between the exhaust ports where as the DOHC spark plugs are on top of the head..


burnt spark plug wires are a bitch!!!!

iirc, i always thought the lower compression of the ka24e was better for the turbo...
