ka24e cam

[chickenmanq]

I'm curious.  I have the ka24e in my 96 truck, and I'm thinking it's not the exact same as the ka24e in the 89-90 240sx's.  If not, I was thinking the only thing they would have changed is the cam, and the engine computer.  So technically, if I got a cam for that year 240sx, could I put it in and order a Jetchip ecu for that year 240sx, and make it work?  Anyone know about that?

For chips I'd personally check out <a href="jimwolftechnology.com" target='_blank'>jimwolftechnology.com</a> and if they are the same engine (pretty sure they are), <a href="www.pdm-racing.com" target='_blank'>www.pdm-racing.com</a> sells KA24e cams.

JWT is too expensive. &nbsp;If I'm gonna get one, I'm going to go with one from Jetchip. &nbsp;www.jetchip.com.

[drifterx]

who makes cams for the 90 240sx?
i didnt know someone did
plus would i ahve a problem passing emmissions?

[chickenmanq]

You got me on emissions. &nbsp;I don't have to worry about them. &nbsp;Check out the post konkman put above mine. &nbsp;PDM racing. &nbsp;I think there may be a few others. &nbsp;Just do a google search. &nbsp;Should be able to find something.

PDM sells cams for ka24e.

You get what you pay for, thats all I got to say <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

I would definitely go with Jim Wolfe over jetchip. Their service ismuch better, they're willing to help out. You get what you pay for, as Ca18guy said <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>.

[chickenmanq]

K, that's all well and good, but I was asking more about if the cams were the same in 89-90 sx's, and 96 pickups with the SOHC ka. &nbsp;I know they're both KA's, but I would imagine the cams are different. &nbsp;Does anyone know?

[chickenmanq]

Besides that, a 200 dollar difference for the same ECU with performance coding is quite substantial. &nbsp;Does someone have bad stories? &nbsp;I could care less about customer service. &nbsp;I was gonna order it off the web and install it and go.

[konkman]

You need to remember you do get what you pay for. &nbsp;JWT has years on Jetchip as far as research and development. &nbsp;Besides if you get something from JWT they will take your personally upgrades into accound, as far as NOS, turbo's, superchargers, and fuel delivery upgrades and burn you a cutom chip. &nbsp;

If you just running on your stock engine with minimal mod's Jetchip, I think, would be fine.

[chickenmanq]

Yeah, I might think about it. &nbsp;I do like the idea of having a personalized chip. &nbsp;In the meantime, though, does anyone know about the cam deal?

[S13Grl]

I think that there is a difference in material of the block and head. Not sure though, someone help?

[ca18guy]

If I had to guess I'd bet that the cams would be different. You have a cam set up more for torque, while the 240sx probably has a Cam set up more for revving and higher HP. Just a guess though. If I had that truck I would swap in a VG30ET out of a 1st gen 300ZX, but hey thats me <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

[Gold240se]

They might have used different compression pistons, like in the KA in the Altima and the 240. &nbsp;I'm not sure though. Just a thought <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

[chickenmanq]

Actually, I just sent an email to PDM racing, and from what their description says, I'm pretty sure the cams are the same, which leads me to believe the ecu does a lot of the distinction between high and low torque. &nbsp;I imagine it could be monitored by fuel curves and such. &nbsp;Even so, I may get a slightly upgraded cam from them.

[transient]

How much does it actually cost to put stronger cams in, and what are the advantages/disadvantages?

[chickenmanq]

It only cost 150 bucks for the cam, and I'm going to put it in myself, so I ain't worrying about labor. &nbsp;The second in the series of upgraded cams requires milling the cam towers by .30. &nbsp;This, you'd have done at a machine shop. &nbsp;I imagine it wouldn't be over 60 bucks. &nbsp;(hour of labor) &nbsp;Benefits are better breathing, more midrange and high end pull. &nbsp;It can open the valves longer for increased fuel input, and increased exhaust ouput. &nbsp;Etc., etc. &nbsp;Just gives you more horses. &nbsp;Too much cam, though, and your low end goes to ####. &nbsp;But if you have a racing engine, why would you be driving it below 3,000 rpm?

[whateverjames]

i've heard the intake manifolds are different.

[chickenmanq]

You know, I didn't think of that. &nbsp;That would explain more than it being soley the ECU. &nbsp;I don't know if they are different. &nbsp;Anyone else?

[S13Grl]

I'm sure the intake manifold is a bit different, but I honestly don't think it should affect the cams at all. It can't be that big of a difference if the engine has the same hp and torque output and is the same displacement.

I also don't think we should even compare the Altima KA to our KAs. Altima KA is less hp, less tq, front-wheel-drive, etc...

[whateverjames]

hellooo. the guy i just bought my transmission from just happened to install a 93 SOHC truck engine in his car..and i asked what the differences were:

first off, he thinks the cams ARE different, because it seems to not be as rev happy, but has more low end torque. &quot;the intake manifold was WAY different&quot; &quot;the disbributor had the coil and module inside it, and the 240sx, doesn't.&quot;

actually irena, the 97 and 91 240sx's are rated at the same displacement, horsepower and torque, but have different cams <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

i don't remember him saying the ECU was different, it could be, but he didn't mention it, i forgot to ask. he said the pulleys are different as well. also he had a some kind of filter on his MAF, a vacuum filter i think he called it.

[whateverjames]

also wanted to mention that he's had quite a few 240sx's, and he had has two of them right now, and he thinks the one with the truck engine has more low end, but not as much high end. also i think the cams are possibly different because on pdm-racing.com's website, it says they CAN get cams for altimas and pickups but they don't have them in stock, i think if they were they same, they might have said they are compatible.

we don't have any solid evidence that the cams are TRULY different, maybe compression ratios are different? but that's the info, and guesses i can come up with.

[chickenmanq]

Thanks for the info whateverjames. &nbsp;I emailed Don Nimi at pdm, and when he writes back, I'll probably be able to answer my own question. &nbsp;I'll definitly fill you guys in, though.

Dude, I OWN a '91 <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>. '91 was the best cams they ever built, even with the same hp output. Anyway, I know the cams are different, I was trying to say that we shouldn't compare the Altima's KA and our KAs to each other. That's all.

[MazingerS14]

I know I'm joining this late. &nbsp;On the issue of upgraded ECU's and costs. &nbsp;It is JWT and maybe G-Force (think they got bought by someone) or nothing else. &nbsp;The others just piggy back some crap PROM to the existing board (with little or no programming). &nbsp;I don't care if it only costs $150, it's $150 thrown away. &nbsp;I have seen and heard of tests where these other brands of chips have identical power curves of that of stock, others have even less power! &nbsp;I guess if you just wanted to raise the rev limit of fuel cut out these would work, if not they suck.

I think the intake runner length of the two manifolds contributes a bunch to the engines characteristics. &nbsp;Just ask someone that has a SE-R with a high port engine and a low port engine, they'll tell you.

[chickenmanq]

Dammitall. &nbsp;The point at the start of this was cams. &nbsp;Cams cams cams. &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'> &nbsp;Anyway, check the new topic titled &quot;Cams!!&quot;. &nbsp;I got the answer from Don Nimi.
