Is there a major difference in the heads from a '91-'94 KA24DE and a '95-'98 KA24DE???

Can the earlier head be utilized on the later block/intake? If so, what is involved in doing the installation of the ealier head, asside from utilizing matching valve cover for it? For instance, are the intakes the same? Do the upper-timing covers interchange??

Thanks for your help...

there is only one KA24DE head.

Are you sure about that??? I was under the impression that the valve covers were different and wouldn't interchange between the earlier and late version.

What about the Altima motors? Is there a difference between the RWD and FWD version of the KA24DE??

I'm trying to put together a spares package for next season and I'd like to get a couple of engines put together to cycle through the program, so I'm looking for sources for heads, blocks, etc. Any info would be greatly appreciated. The more detailed the better!

Thanks for the :help

could u be talking bout the headfrom an '88+ - '90 ka24e? vs 91+ ka24de?

i would believe ther would be

No, and no the ka24de is the same ka24de in an altamia and im 90% sure there interchangeable. the differance is the transmssion (in the RWD 240) vs the transaxle (in the altima)

umm again im 90% sure of what u mean. if ur saying u wanna build a couple spare engines.. u might look in to gunkyards. try an find a 240 / altima w/ a trashed rear end ( and a working engine) pull the engine and poof u have a whole engine of spare parts for a couple/few hundred beans u prob will want to get a extra engine, unless u get 1 in realy good condition.

just remember "Cheap... but used. New.... but expansave."New always gives u peice of mind but w/ a price tag its 3500$ for a new ka24de 0 miles but u may be able to get a ka for 350$ (used) its ur call but i think if u wanna tinker w/ the engine get a used 1 u lose less money when it brakes.

No... I'm definately not considering the single cam motors... Only the '91-'94 DE vs. '95-'98 DE... I have a head from a '92 KA24DE that I'd like to be able to mate to a '97 KA24DE block...

Sounds like they are the same... or very similiar...

the altima motors have a different dist system and it sticks out differently than a 240 does.

OK... so can the Altima head be used on the 240 if I use the 240 upper timing cover? Can the Altima block be used with the 240 head???

No no and no.

Well... I guess that negates your previous post that "there is only one KA24DE head"

If I'm understanding this all correctly, the head from the '91-'94 KA24DE motor and the head from the '95-'98 KA24DE motor should be able to be interchanged, but the Altima KA24DE head cannot be used on any of the rear-drive motor applications...

my head hurts... :eyecrazy

Banzi, any year dohc 240sx will work, no Altima stuff will.

king240 why buy a bmw when a 240sx will do?

y buy a bmw when u can have a 240? or a 300 or 350......

whats different between the altima / 240sx engines?? i would assume nothing (siginfant n e way) its the same engine code wouldne that mean theres no differances (hence same engine)

i know the engins are transvers vs regular aside from that the compression / hp n toque are different y is that? ideas n e 1?

this is retarded.....DE------------ES!

To answer the question, there ARE differences. The 91-94 head is milled for a different valve cover, with different size threads and placement of the bolts. Another critical difference is the 91-94 heads do not have the bolt hole tapped behind the upper timing cover where the distributor meets up in the same place as the 95-98, so using a an earlier head will cause an oil leak if that's not sealed. Sunbelt Motors showed me that trick. The Altima head isn't even close to the same, but we ALL knew that I hope.

Haha, speeding monk! I'am an avid solo 2/1 enthusiast, I regularly give a local dud fits, he races his 99 M3, I quite often (not always!) will better his time, so depending on how you read it, its a sort of slight towards BMW's. I also use it on our local motorsports forums, he reads that one!
