"ka25de"

[R-Yahne_240]

my boy has a ka24de and he wanted to bore it out to a 2.5 L which would make in terms a Ka25de motor he said it would push out 325hp and 290 tq i think hes full of it

have you seen it done what mods where made and what was the performance of the motor when done

also the rough cost of boring out and building the "ka25de" motor

[Florida240sx]

Roflmao.1more displacement and you get 3times the power.......lolnot many have over 200hp N/A Think a couple are close to 250 but that's it.Better to go turbo then do the crazy engine build.

[S13 240SX]

1 more displacement woudln't give you ****!!!! the ka already can't even rev happy just the way it is, so a 2.5 wouldn't even help ya boy out.. tell him to go turbo or nos

[pregmantis]

It depends on what "else" hes gonna do to it. there are plenty of motors making over 275hp NA and there are some reaching 350hp.

[AeonTorpor]

But how many NA KAs do you see in that category?

[emperor_lunchbox]

Today I saw a race version of a NA 240 from somewhere in Canada, He is making 211 at the wheels, with very extensive work. If your boy is building a race car and the rules of his club do not allow a turbo I say get another car, but if he is just trying to get a street machine, turbo all the way. For half of the money it would cost to build a 200 HP NA 240 you could have a pretty bad *** KA-T or even a stock SR20 with some minor bolt ons.

Wow, 130 hp per liter. Honda's S2000 can't even match that and it has to spin near 8000 to get to 120 hp per liter.Now if you had misheard or your friend misspoke and the number was 225 hp, in crank hp, 190 lb-ft; that would be more believable with appropriate other mods.That would be 90 hp per liter, which is much more realistic for the ka.

Just by boreing the engine out to 2.5, with higher compression, you might be able to push 170. Maybe close to 200 with intake, header-back with test pipe, and a tuned ECU.

Haha maybe a turbo 2.5 could push 300 without too much work (aside from the turbo)

There are multiple KAs making over 200whp. Sorry to burst your bubble there.

Also, 20% drivetrain loss is probably what you're assuming, which is a bad assumption. Most stock 240s have around 16%, and his probably has some drivetrain modifications. I wouldn't put the crank horsepower over 240 or so.

You are reading too quickly Insanity.First, the engine hasn't been built yet.Second, I never said that there weren't KAs making over 200 whp. No bubble there.Third, I never assumed whp (never even mentioned it); crank vs. wheel was never stated in the beginning of the thread and I made the assumption of crank. Go ahead, fault me for that.Fourth, I went out on a limb and suggested that the numbers might have been a mistake and subsequently suggested some more realistic numbers for a ka at the crank, naturally aspirated (which was an assumption based on the board we're in). That statement was started with an "if" indicating that it was a suggestion of a possibility, not some undying opinion of mine- just a guess.In conclusion, you estimated that a built 2.5L ka would not put out more than 240 hp at the crank. I suggested that 225 hp at the crank would be a realistic number for the ka. So we were 15 hp off in our guesses. Whoop-de-doo.Yay, reading is fun.

Were you responding to the original post or the one that stated 211whp?

[skatanic28]

There are multiple KAs making over 200whp. Sorry to burst your bubble there.

where are the dyno charts of these multiple ka's?

[InsanityInc]

where are the dyno charts of these multiple ka's?

Scattered around. Like I said, not all of them are in 240s, and most of them are single cams, actually.

Original post. Otherwise I would have quoted.

[InsanityInc]

Original post. Otherwise I would have quoted.

I was assuming you were going off of the 211whp number when you said it was bull****. Obviously the original post is bull****.

[Ajax]

okay, I see where you were at. 'Sall good.

click the picture of the 240 to see the car with 211 WHP

[pregmantis]

Sorry aeontorpor, I was actually talking about NA ka's

[emperor_lunchbox]

actually is http://www.anothershade.comYou will want to click on the cars button then click on the picture of the 240 and you will see his specs and his claims of 211 WHP

[91RMKS13]

i have seen a stroker kit that claims 195hp and 205ft/lbs for two grand with compression ratios from 8.5/1 to 10.5/1 the kit is a little over 2 grand and you can order the crank knife edged for an additional 200. I cant remember the site off the top of my head. but i will try to post it later. But to me 2 grand does not seem that bad for forged rods, pistons, piston rings, crank ect.

Sorry aeontorpor, I was actually talking about NA ka's

I really don't understand what you are trying to say here. Do you mean you were or were not talking about NA KAs?

It depends on what "else" hes gonna do to it. there are plenty of motors making over 275hp NA and there are some reaching 350hp.

I was just saying, there are deffinately plenty of motors making that much HP while still being NA, but, how many NA KAs do you see in that category. I'm not trying to be offensive or anything, but I may be over thinking this.

Yeah, I deffinately think you're not getting anywhere close to 325hp and 290 tq out of a NA KA, 24 or "25".
