Stroker Kit?

[40oz]

I was looking into getting more torque and increase my displacement of my ka24, i went ot the JUN site and they don;t have any stroker kit for that engine yet they have it for the skyline and the sr engines. has anyone heard of one for the Ka24>??

There is a reason JUN don't have one, its a Japanes based company, so i doubt they would make a stroker kit for such a small amount of cars in a different country.

Anyway I don't think there are many stroker kits, but IIRC there was someone who had the chance to buy a prebuilt engine (forget the company), but I think it had a stroker kit in it, so look for that thread and try asking the company, I would assume that it would be a custom thing that some higher up shops could do for ya.

Are you serious??? Think about this for a second, the KA motor has never been used in Japan, ever. Why on earth would JUN, a Japan based company, build a stroker kit for a motor in the USA that is just now starting to get tuned into a high performance motor? Waste of money and they would never sell enough untis to cover costs of production and shipping.

Stroking a KA would be pointless anyway. Want more torque, swap in a VG or something.

[boro240]

i thought they had the KA in japan, but only in trucks or something.

[240Driver39]

Wait, im not really sure, but isnt the ka a stroker motor already?

[DuffMan]

The had a KA20DE in a van.

HAHAHA YET! HAHA try never. i think ka is a stroker engine, if you want to stroke it, i hear a z22 or somthing crank will fit, and that might make it stroker...

[sykikchimp]

no, there is no such stroker kit.

You could stroke the engine.. not much point though, because the motor is (get this) ALREADY STROKED.

please do some additional research on the subject, then think again about what your goal is. obviously you haven't quite got a handle on the subject yet.

that is a myth.. doesn't work. I believe the journals have a different diameter or something. There was a guy on FA a while back in search of the "OEM" destroking kit for the KA. That was one of the first things he tried.. with no success.

www.importperformanceparts.net/import/strokerkits_comingsoon.html STROKER KIT FOR THE KA!!!! I think that there is another kit out there to I cant remember who offers it but if you want i can find out for you (I have it written down somewhere) I actually found a place doing a survey for stroker kits. I was thinking destroking, but I dont know if they actually researched the engine or not, so I guess they are going to stroke it even more. either way with destroking or stroking you are going to get flamed. Its all good even Ka-t's get flamed. almost anything about the ka gets flamed. Just research things make the best decisions that you can, and do what you want to do!!!

[Zemus]

Link doesnt work.. interesting, i really want to see this, and have questions.

What would the HP gain be?

What would be to gain by a stroker kit?

try [email protected] they are a division of importperformceparts (or the other way around) that is the web site that had a survey for stroker kits. I wonder if anyone other than me voted for the ka. They sent me an e-mail awhile ago telling me that they were going to look into the KA. so maybe they saw an opertunity to improve it somehow and apparently they are going to make it happen. the above link was supposed to take you to a list of stroker kits that were on the way including the ka (shceduled for march) I dont know if it would make more horsepower but it should make more tourqe. It depends on wether they stroked it or destroked it. we should all contact them and try to get a destroker kit as well as a stroker kit (yes I already have my flame retardent suit on)

[kapower]

www.importperformanse.net they are a division of flatlander racing They want to know about parts that are in need but not in existance like destroker and stroker kits. so if there is enough of a demand they will build it. they are still having the stroker survey. they already carry 700 kits as of now! and cliam to have the best prices on them. I found a highflow oil pump on there for $99! I did not even know you could get a high flow oil pump for the Ka that just bolts on. It seems like an opertunity waiting to happen for the ka! If anyone has an idea you should let them no about it. :D

[talonraver]

i've heard of the 2.2L stroker for the s15 but i've never heard what the performance differance is. what kind of displacement differance are we talking about when stroking the KA, 2.6....2.8? A 3L 240sx would be one hell of a ride.

[kapower]

I do not know that many details, I think they are still considering it. however, I do know what each kit contains; 1-forged crank- - custom forged pistons(any compression any bore)- -forged steel pins(ultra lites available)- -piston pin locks- -plasma molly racing rings- -forged 4340 steel or billet rods- -toga performance m&r bearings. I would personly like to see more rpms (around 7500-8000 rpm's and around 2.3 leiters) without having an unstreetable cam. an engine like that would have displacement, tourqe, and high rpm's perfect for spooling a large turbo(and actually having decent sized power band) I dont think you can take full advantage of a large turbo without high rpm's.(I could be wrong correct me if I'am wrong). I mean what is the use of a large turbo that hits full boost 1000 rpm's before redline. you would have a massive amount of lag and then an ungodly amount of power but only for 1000 rpm's. would'nt a 2.3 lieter engine that could rev to 7500-8000(safely) take more advantage of a properly spected turbo than a 2.4 leiter that only revs to 6500-7200(with a cam)?

[Zemus]

sounds very cool, but stroking an engine would be a **** load of money from what it sounds, atleast 2k, and really what is thier to show for it, other than you have a bit more HP and can rev higher

[kapower]

this place is high volume, they have over 700 kits as of now and some of them are as little as $800! If the crank that comes with the kit is stronger and balanced better than it would be worth it. people spend money on rods, pistons, rings, bearings, and crankwork any ways so it probally comes out to around the same price range. It is not a mod for everyone but it could be benificial to some trying to go that extra mile!

[kapower]

if anyone is interested in this mod they should contact flatlander racing. Or if anyone has an idea for a part that is hard to find or non existant they should contact them to have it built. I think it would be benificial to 240sx owners, and the under devoleped KA! I probally sound like a employee of this company but I'am not I would just like to see a company get interested in the KA engine series. There are hundreds and thousand's of people with ka's and many different types of cars with Ka's. the ka will never be developed to it's full potential without reseach, money, and people that want to modify the engine that Japan gave to us! peace out people, this is a great forum that we have here let's use it to the fullest advantage that we can. :)

800 for the whole kit? Or just the crank

[kapower]

they say that they have the cheapest kits around. I meant to say that SOME of the kits start as low as $$$! they have the kit on the soon to come list but I just looked for it and they do not offer it yet. Although they say they can build anyone any custom stroker kit that they want! I wont speculate on prices though. I just dont know.

[sykikchimp]

Stroker kits don't generally add power.. they add potential. Such as the big HP drag SR20's in japan.. they run the 2.2L stroker kit, to spool a massive t51.

Wouldent a stroker kit really mess up the KAs power band, from what i have gatherd it would change the Redline and give it more tourque. But a DE-Stroker kit would give you higher RPMs, but i see no gain, other than high reving.

Also that "KIT" for the stroker, they will give you whatever compression pistons you want? And you get Pistons, Rods and Crank of 800? Are you sure?

[sykikchimp]

800 for a crank, pistons, and rods is unbelieavable... and if it is that much it makes me question quality?

yea, i have seen pistons for 400 and rods for 300, but i dont know about a crank still for that cheap

[kapower]

I never said that the ka stroker kit was $800. I went back to the site and I found a couple stroker kits for V-8's for $1,299. they DO NOT have A price available for the KA. as of right now you would probally have to get one custom made. After thinking about it for awhile I think that the ka is a perfectly good stroker,(I was only considering de-stroking it) I will probally just get a custom cam made to get the higher rpm's that I'am looking for. (I still think it would be nice to destroke the ka 0.1 leiters though) how much de-stroking would it take to make the ka perfectly square?(or to the socalled ideal stroke)?
