ITB KA24e, where can i get them

[Zemus]

Ive seen ITB's for the SOHC Ka, but i have never seen them at sites. And dont yell at me for not searching, cuz i did. Also what is the HP gain? I am very interested.

[fogleroller]

someone pointed me in this direction

Wow the kits are like 3k wow thats a **** load, how much HP will i gain?? It best be like 50 or it would be SOOOO not worth it.

[Zemus]

Any other places, i emailed them.. I would have edited the post, but it wouldent let me :-/

Individual throttle bodies aren't a common setup, thus they are going to be custom made (and usually pretty damn spendy). I've seen it done before, with pretty great results (don't have any concrete numbers though :-( ).

[DSC]

IIRC they give 20-30hp, but I can't really say what they'd do for you. I think that number was after high comp pistons and stuff.

Thanks for the #s, i say im going to do lots of mods and one day do that

Talking about absolute power gains with this type of thing is pointless. What's not stupid is talking about what kind of power they can support, though. KA24E's with ITBs or sidedraft carbs have produced upwards of 300hp, NA... in applications like GT300 and IMSA GTU cars.

Really! do you have any sites were it shows these cars? I would love to see a 300HP KA24E, please :)

I had seen a SOHC (on the web) with a similar setup that made 240hp at the flywheel and nearly as much torque. Ok, not as impressive as the 300hp one, but you have to give it credit :D

[Phlip]

There is a guy in texas that has a KA24DE in a 510 racer running ITBs, but I am sure that he is running a custom setup and was making like 240 at the wheels or something like that...

[Zemus]

Thanks guys, i would like to see if i could find site that has a 240+ KA N/A with a list of mods, so i can see what i need to do to get that kind of power.

If HP numbers are your most important concern then go turbo...trust me, a 240HP NA KA is not cheap. If you want something a little different and do not mind that your fellow 240SX brother who has a nice turbo has over 100HP more than you, then pursue the NA set up.

I want somthing diffrent, but i want it to be fast, i guess Turbo HP and N/A HP speed are alot diffrent. Yea, i am doing the KA cuz i dont have the ability to save up large sums of money, at one time, so i can just add to the current engine and get good HP. Also im not about streetracing, im about autocross, and i would be very interested how to do this whole z22 crankshaft thing, anyone here like really good with knowledge of the KA24e?

Also, how much HP you running

I still have yet to dyno my car...but plan to before the summer. I am also not satisfied with a few odds and ends in my set up...ignition control is the main thing that needs work. But if I were to guess based on current fuel maps its barely over 200hp at the crank. Like I said, it still needs a little work.:(

Thats not that bad, is it a 24e or 24de, and can you list your mods

It's a KA24E with TWM ITB's, worked head, Nissan Motorsports "R4" cam, 90mm pistons, 9.0:1 compression, hotshot header, N1 exhaust.

how much did u pay est for all of that?

[xchaosx]

What are you doing about management? are you running a standalone?

[DuffMan]

Reviving old threads is bad luck and will cause you to DIE

[Bill Roberts]

Dude, your post is 8 months late. Goddamn! Do a search for the progress to get redated.


2 months here is an eternity in the learning and doing curve.


As per KAE, search my name, lots of updates and No standalone for KAE needed, just rawbones pump.

Thats James' car.. its a pretty peppy KA, felt pretty good when I drove it.

Getting lots of NA power out of a KA is no easy task, anything over 200 starts to get pretty iffy from what I hear, if you want to keep the motor "streetable." You end up running into a brick wall when it comes to pump gas, because there is only so much octane you can buy on the streets. The motor will be high revving, rough idling, and hard to find fuel for.

Well, then there is turbo.. its cheaper and in most cases, easier to attain.

If you are going to build a KA, talk to a reputable motor or machine shop that builds motors. Last I checked, you're easily looking at 3000-4000 for a 200-220HP built KA. Expensive, but worth it if you are a KA freak. It all comes down to what you can justify spending money on. I dont think I would spend that much on a custom-built KA motor, I dont like the design of the motor that much.

whoa this thread must be old. i am happy to be one of few ka24e tuners. itb is always going to be to expensive, carb setup isnt exactly cheap either. your intake manifold and efi system can bring you easily up to 220 crank hp. your focus should be on the engine build. the necessary head work and valve train parts will cost you the most. i hate to say it but the nico ka boards have a lot more info on the ka24 n/a tuning approach.

in other words, dont be so stuck on the itb idea. it does not make the engine
