240sx KA24de head work on an altima block?

Post by **Blue Blunder** » Sun Feb 29, 2004 11:00 am

Just wondering if any knows if a S13 KA24DE head will bolt up to a altima KA24DE block, manifold, etc?

same motor, i believe its even got the same cams and everything, should bolt right up and run

you should be fine with the head, just double check that there is a distributor port on the exhaust cam side. the 240 motor has the distributor on a pole if I recall correctly on the opposite side of the motor.

really? tahts hte first ive ever heard of htat, maybe i just never noticed all this time

Post by **Importroller** » Sun Feb 29, 2004 11:00 am

if you ever looked at the motor, the distributor for the RWD KA is on a pole on the driver's side and the side of the head thta the FWD distributor would be is back against the firewall. So you would need to see if there is a way to put the FWD distributor on the RWD head

hmm, i just checked my 24o and you're right, although i have no KA altima to compare it to, i believe you, i dont think taht would be a huge problem if you really had the time to figure out a solution though

A solution may be able to be figured out, but there is no way to relocate the entire distributor because no matter how you slice it it still needs to be connected to the block

sounds like someones got some tough thinkin to do

THe head should bolt right onto the block just fine. I just dont know if the opening for the FWD distributor that has the cam sensor built in has an opening for it to mount into the side of the head of the RWD, or the 2 holes needed for it to be bolted to the head

I doubt highly there is anough room for the 240 timing cover in an altima engine bay. The crank driven dist. has that piece that runs both the oil pump and the dist off of a worm gear on the crankshaft. The altima block has no worm gear and thus a different timing cover. I believe...I could be way wrong too.

^that doesnt sound all that confident, but unfortunately u may be right,

same motor, different cams and everything Rev mentioned...

which is why some people swap the Altima exhaust cam in the 240...almost 10 HP guaranteed for the relatively easy swap. and cheaper than aftermarket cams if you can find a junked Altima KA.

the cams are the reason the 240 KA24DE doesnt have so much more HP than an Altima...us Alti's have lower compression, but hotter cams, while the 240 has higher compression, milder cams, resulting in only 5 more HP/TQ.

ive done my reading

hmm, thats a pretty good idea, i might have to look into getting alti cams for my 24o if they're cheap.

Post by **Asleep Altima** » Sun Feb 29, 2004 11:00 am

theyre very cheap. i could have gotten both cams at the salvage yard for 50 bucks. the price you pay when you leave is determined by the attitude you walk in with at salvage yards.

Post by **nlzmo400r** » Sun Feb 29, 2004 11:00 am

so you're saying be stern? or just go in not looking for anything inparticular?

Post by **Asleep Altima** » Sun Feb 29, 2004 11:00 am

no actually im saying go in there with a totally cool attitude. in other words, dont be cocky and dont be a d!ck.

Post by **nlzmo400r** » Sun Feb 29, 2004 11:00 am

oh, sounds good, i was about to ask why i should go in there like a hardass. I think after i get my gauge cluster im gonna get some of those cams. How's the install, never done cams before? 1pstn to TDC and then install?

Post by **Asleep Altima** » Sun Feb 29, 2004 11:00 am

not that hard to do really. just have to be patient and take your time. ive got the instructions for it when youre ready to tackle them, plus a couple of side notes from what ive learned personally.

Post by **nlzmo400r** » Sun Feb 29, 2004 11:00 am

sweet, ill do that as soon as i get the cams, although i got a list of priorities ahead of that as of now, so it'll wait a few weeks

Post by **Asleep Altima** » Sun Feb 29, 2004 11:00 am

we gots nothin but time.

Post by **nlzmo400r** » Sun Feb 29, 2004 11:00 am

haha, thats pretty evident

to answer the original poster: The altima dist has a key rather then a socket for it to be driven. That key plugs directly into the exhaust cam shaft. The cam shaft would have to be for an altima. the cyl head would have to be stripped of its 240 parts and have the altima parts installed for it to work. This is also providing there is a hole in the rear of the 240 head to accept the dist. I do believe on the 240 there is a gold plate covering that whole but would need one of you 240 gurus to confirm that since I dont have any 240's in the shop right now and the schedule does not show one coming in today.

you dont have to set it to TDC, but try to rotate the motor before you take the cams or chains off. rotate the everything so that the timing marks line up together. that way when its time to reassemble, you wont have any issues. I dont know how much mechanical experience you have, but the head gasket job on our car is very time consuming, and you will need to be patient....especially when you are taking the timing chain, and main sprocket on and off

Post by **Asleep Altima** » Sun Feb 29, 2004 11:00 am

ive youve never done it before, its about a full day job. once i figured it out, i could take the cams in and out in about an hour... lining them up is the most critical part. took me several tries to get it just right.

Post by **nlzmo400r** » Sun Feb 29, 2004 11:00 am

see thats he only thing im worried about, but right now my car is running great, and i just got some SE rims (with 4worn out tires and one good one which is flat..wooohooo) so since the plugs/wires helped so much, im pretty excited and am gonna save up some more $ for a month or so before i dive into something else

Post by **Altiman94** » Sun Feb 29, 2004 11:00 am

I would just fix whatever you can to get the car running as good as you can. That's the game I played when I first got my 240. I can finalyl put some money into performance after i get my audio system bug worked out.

Post by **nlzmo400r** » Sun Feb 29, 2004 11:00 am

well see hte next stuff i have to do im kinda skeptical about. I dont know how to replace the front crank seal (dont even know exactly where it is for taht matter) and the P/S hoses are gonna be a biotch im sure. Nissan wants 465bucks to replace 1oo dollar P/S hoses, so its gotta be lots of labor. Besides they're probably just gonna pull the whole rack and do it, see i dunno how to do that, and dont have the tools to do that
