Anyone here do the 2.6L stroker kit?

[Flicktitty]

Hey guys i was just looking at my friends website http://www.NA-DREAMS.com and i saw that they have a KA Stroker kit up to 2.6 the company that makes them is IPP sounds prettycool here is a direct link to the stroker kit! - http://www.na-dreams.com/catal...=1857

stroking your ka is not a great idea. i did a lot of research on it and found out it causes too many cons with not a great increas in displacement. the worste of which is that it will lower your rev. limit and for the money it costs you can do so much more to your ka.

[Flicktitty]

alright i just thought i'd see if anyone has done it... well anyone else wanna chime in on the subject?

[S13 240SX]

I'll chime in, yeah the 2.6 kit is a joke!!! why do it if the ka24 the way it is already is not rev-happy, throwing in a 2.6 kit makes it rev even more ****ty!

[koukiKA240]

If you stroke the KA, put it in a hardbody and make sure that truck just pulls tree stumps out all day, it will be damn good at that but not so good at going fast.~Sam

[Flicktitty]

so with all the negitive response why do you think they made it? someone somewhere must of thought i was a good idea?

[S13 240SX]

yeah a good idea to get somebody's money! that 2.6 liter kit is a lot of damn money and they would probably think people that don't know anything about engines would just go right ahead a buy it, its kinda just how honda people think spending all that money on their intakes, and exhuast and wings, make their cars go really fast, but really makes them sound like butthole, and with the wing that makes it look like a jet!!! kinda like that!

well lets see, if the crank is custom made, fully forged, and fully counterweighted, wouldn't that let it rev more? i mean the stock ka doesn't rev high partly cause of the long stroke, but as i see in the ka section about fully counterweighted crank topic, its the half-counterweighted crank that doesn't let us spin it more, so which is right?, that is if that crank is really fully counterweighted.

this is just a though, though the whole 2.6L assembly is still too expensive so thats probably why nobody has tried it.

[S13 240SX]

TheOne, I hardly doubt that with a full forged, 2.6 liter kit, and fully counterweight would let it rev more, i hardly doubt it, due to because the stroke is already too long enough on the KA, and wouldn't throwing in the 2.6 liter just make the damn stroke even freaking longer. So it's pointless to make the damn stroke even longer!!! and Just like Iamjohnhayes your making the rev limit shorter and like i said making it even more rev unhappy.

Oh and even if all that crap did help rev faster, the problem is this and its a major problem if you plan on drifting on that setup... here's the other problem, you won't be able to consistantly stay in higher rpm's and if you do your be blowing up that crap skyhigh

[Flicktitty]

hmmm i understand now. just thought you guys might like to see the kit

[Chezedik]

I would think that the fact that it is fully counterwieghted would make up for the slight increase in stroke. A mm or so. So, really what it is all about is spending a grip on a little boost in power, since simply increasing displacement .2L won't make a ton of power. But if it is something you are thinking about you could also bore the motor over 1.5mm and have a 2.75L. With the right turbo, you would never need to go above 6K. That would be sweet. But yes, potentially a bomb above that.

[sunnys14]

i dont think 2.6 is such a bad idea. they make stroker kits for SR20s that increase their displacement to 2.2... 2.6L ka-t would be ok i guess

[Craving4Boost]

overboring the pistons increases displacement doesnt it? or no?

[hannibal]

yep, but an overbore of 0.5mm (pretty standard) only increases displacement by 27cc.

scroll down and u will see the kit... tells more about it... i wouldn't mind trying it with 8.5:1 pistons and turbo it... alot of fast cars dont rev past 6gran .... remember, not a honda motor here, so it will have lots of tq and make a good street machine

[S13 240SX]

i dont think 2.6 is such a bad idea. they make stroker kits for SR20s that increase their displacement to 2.2... 2.6L ka-t would be ok i guess

rightttt,, good idea for the sr20... but for KA bad idea.

[S13 240SX]

I would go no more than to bore it to a 2.5 Liter, 2.6 is taking it way tooo far.

[savatoge]

General knowledge (and in the FSM too?) is that the KA can be bored over a max of 1mm (.040") to arrive at a bore of 90mm. Going beyond an overbore of 90mm results in cylinder walls that are too thin to operate in a reliable and safe manner. Have you spoken with the people that would be working on your block? If so, have you discussed what final bore dimensions your block will have?

The stroker kit web page here:http://www.importperformancepa....html...provides specs on the new displacement:With Original CC's = 2389cc'sNew 102mm stroke.Max cc's 2621 (90.5mm bore)

I looked into this stroker kit several months ago, as I was curious about the details concerning the kit and what all it entailed. What's interesting is that before I called Flatlander Racing about this stroker kit, the web page had the following listed:

With Original CC's = 2389cc'sNew 102mm stroke.Max cc's 2614 (90.5mm bore)

(I calculated 2625cc's given the above bore and stroke...a stroke of 101.5mm will give 2614cc's. Why did they round up on the stroke measurement? No need to artificially inflate the numbers, is there? Also, I have my head displacement at 43 cc's. Is that correct? Maybe that's where my calculations differ from theirs)

In that portion of the page, they had listed the displacement change as a net of an additional 225 cc's. But at the top of the page, it also had listed:"IPP's stroker kit consists of 5.5mm more stroke that when added to the increased bore = 440cc more cubes of usable power!"

So, now operating at 2829 cc's and a stroke of 101.5mm (don't know why the switch to 5.5mm more stroke, when they listed 102mm earlier)), the bore would now have to be 94.18mm, meaning an overbore of a whopping 5.18mm.

While I was on the phone with one of their reps, I asked about why the numbers on their site didn't work out right...he said that the page was relatively new and that they were "working out the kinks"...take that for what you will. Anyway, if you're going turbo on the KA, they don't suggest going above 1mm (or .040") overbore. 90mm is their recommend bore limit on the KA for turbo applications. If you're going for a NA setup, they recommend up to 1.5mm over (.060") and high compression pistons...the guy said that in their records he saw where someone got a KA bored over at 2mm (.080")! I asked if he had any data on the sonic testing for the 2mm overbore and he said that they didn't keep records like that around for long. Seems to me that on a block like the KA24, where you know you might have problems on a consistent basis by going too high on the overbore, you might want to keep that kind of information around.

As far as a stroker kit goes, I would only go with one if you are going to stay NA. If you're going forced induction, I would take the money that you were spending on the stroker kit and put it towards some forged pistons, standard length forged connecting rods, as well as upgraded valvetrain componentry and cams. I think you would be very pleased with the end result, not to mention a more reliable motor configuration.
