cams!

What are the best cams for a ka24det? How much difference are the 264 cams compared to the stock? What is the difference in the feel of the car?

I hear they answer stupid questions like this there...

[jbracy7]

Well the but dump says it's pulls harder, but no real gains it just moved the power band higher into the rpm but you lose some low end.this topic has been done to death SEARCH DAWMIT

[redking15]

Hey a** holes! You don't have to reply ya know!

[danshaz82]

I know there is a very detailed write up of almost all the cam swap options on here. Tons of good info. Also no need for name calling

Hey check it out, THEY DO!

In all seriousness OP, when you come in here asking that kind of question, we can tell you haven't really researched very much on your own. Guys around here will be a lot more helpful if you just take little initiative. And btw, name calling the guys you're asking for help, also not a strong move.

[redking15]

Well if you say good judgement comes from experience and experience comes from bad judgement then give me a break! I asked to see how cams actually feel in a car! Did research, but the feeling in the performance of the car would actually have to come from someone with cams right!? So someone with cams answer! Not the readers who read a lot and have no real EXPERIENCE!

[SX APPEAL]

Actually I believe it was Mark Twain that said that^

But anyhoo, the thread that danshaz82 is referring to goes into all the butt dyno feelings and such as well, and should be very easy to find. Personally I switched from stock cams to 248/232 and the only difference I noticed was that the car sounded a lot better, so take that experience for what its worth :rolleyes

[redking15]

Ahhh! A man that makes sense! Do you still have your ka? What setup ya running?! I had my beast for about six years and I am still not finished! Three heads and two blocks worth. Upload pics later on today. The car has solely been worked on by me except for the next upgrade which will be the computer. Undecided about that one. Where I am from, NO ONE runs a ka. They jump straight to sr20s, rb, 1 or 2j, so I am the only boosted ka in the country. And I just get tired of the noise in the market about the truck motor from guys who can only read and have no HOOD experience (including mark twain, lol). So, what suggestions on the ecu, or piggyback!??

[krash]

I also read somewhere that 248/232 on an s13 KA actually hurts performance? Something about the s14 MAF being different blah blah blah. Does anyone know if this is valid?

[redking15]

’91-’93 240SX (S13) - Note: '94 exh specs are slightly different
intake cam = 240 deg duration with a 1.6699”-1.6774” lobe height
(intake opens 1 deg after TDC & closes 61 deg after BDC)
exhaust cam = 248 deg duration with a 1.6699”-1.6931” lobe height
(exhaust opens 64 deg before BDC & closes 4 deg after TDC)

’95-’98 240SX (S14)
intake cam = 232 deg duration with a 1.6699”-1.6774” lobe height
(intake opens 1 deg after TDC & closes 53 deg after BDC)
exhaust cam = 232 deg duration with a 1.6699”-1.6774” lobe height
(exhaust opens 48 deg before BDC & closes 4 deg after TDC)"

That is the tech about the cams! But I have a set of s13 cams in my closet but never got the chance or needed to put them in. A guy on the zilvia forum said that he didn't feel any less performance, but his car felt better. I guess for me I built my head and now I am upgrading on the cams!

how exactly would that hurt it tho?

Sounds like interweb genius s*** to me... As far as I know, the S13 and S14 MAFS are the same and work on the same principals, only the housings are different.

In my opinion, stock cam swaps do nothing more than move the powerband around a bit but don't contribute to the overall power or acceleration of the vehicle at all (although like I said, some will improve the sound) You're talking about MAYBE 5bhp, which is roughly 3 percent of a stock KA's (when it was brand new) peak horsepower, you move that up or down the rpm range all you like, do you really think it's going to make a hell of a difference anywhere? I don't. Now MAYBE, and this is a big MAYBE, if you account for that same 3 percent in a turbocharged KA, say 300bhp, then thats 9 horsepower, but still, you'll gain or loose that depending on the relative humidity that day and how good your tune is. IMHO, not worth it.

But then again, my old KA, with the 248/232 singing to the rafters at 7,000 rpm was absolutely spine tingling, and there's no one to race in the ozark backroads, so maybe it was worth it...

Oh almost forgot, I was wrong, Mark Twain isn't the originator of my signature phrase, its actually a bit of Southeast Asian wisdom popularized by Scientist and Author Jim Horning, cool huh?

This is such as bad thread.

But in a nutshell, cam lobes are a science. From lift, duration, lober seperation, pairing and split. You need to know what your goals are, why your exspections are. Addind\g more lift allows more air into the clylinder, however .264 is not lift thought. that would be the duration of the cam lobe cycle. Since your now holding the valve open longer your allowing for more air to enter. This is all great fine and dandy but now you have to manage that air. The ecu should be tuned for these changes, other issues are that with more duration you decrease the seperation which is known for the blub blub sounds with cams. This can cause drivability to suck. Adding more lift adds stress to valve springs, and retainers and will usually require an upgrade. You also need to be sure your clearences are good. Too much lift or timing problem matched with a interference engine, BOOM. However 264 264 is not bad, but i prefer more custom grounds.

[redking15]

Well 264 sounds like a good choice for me seeing that I have all the titaniums ready for them. But another question and this is more of an opinionated one, which company has the strongest cams in terms of durability or performance. Let's say the top five conpanies to make 264, who would be the choices. Cause some guys would prefer name brand and some just want the job done. So with all that being said would an upgrade matter from where you are buying if all sell the supposedly same product?

[redking15]

Example: I read an article couple of weeks ago and cusco said people are out there selling oil catch cans with their name on it but they are fakes. What difference does it make if the product does the same job! And I don't mean that it doesn't matter but how can you make a decision if they all do the same thing. Does it only boil down to a matter of choice? Yeah I guess and then who do ya trust? I maybe makin this complicated.

[SX APPEAL]

Yeah you're "makin" this complicated... What-the-ever-loving-f*** does cusco's oil catch can have to do with camshafts for a KA?

Here's the skinny, there's only a couple of companies that make cams for a KA, BC and JW, and they're the same in terms of quality as far as anyone has reported, so find the best deal on the classifieds you can, throw them in, and absorb the imaginary difference in horsepower you want to feel and be done with it.

Honestly, if you want satisfaction, spend the $300 on your wife, girlfriend, or that hot chick at the end of the bar. Cause cams alone ain't gonna do jack s*** in the real world unless you start getting serious with other major engine modifications. Not trying to hate, just trying to save a brother some dough...

[simmode1]

If you've already spent the time & money to properly build a KA-T, please do not waste efforts swapping in any dinky OEM cams.

On another note: Did JWT's site close down?

Don't forget Kelford and Crower, they too make cams.

Nismo too.

[SX APPEAL]

Did forget about them, I shouldn't be allowed to post when I've been drinking. Didn't know Nismo made cams for the KA though, interesting. I still say though that for the most part cams really don't make a big enough difference to justify the cost, not when you can just run another pound or two of boost and feel the same improvement.

[asoomal]

IMO, Headwork > Upping Boost.

[SX APPEAL]

Normally I would agree, but it's been my (admittedly second had) experience that in the case of the KA24DE, there aren't really a ton of dramatic gains to be had from major head work, not enough to, like I said, justify the cost. Of course I'm being a bit hypocritical, I picked up a set of BC 264's for my KA, but mostly because I got a good deal on them and figured they'd make it sound a little better lol. I hate how a lot of the time turbo's kill the musicality of the exhaust note.

[redking15]

SxAppeal that was funny! Understood!
