Double post.

[NemeGuero]

Why does the exhaust manifold go the other way?

What'd he do to ignition?

[TheJerk]

Why does the exhaust manifold go the other way?
What? I don't understand? I do know that manifold is a custom design he made in around 4 hours. It makes more power than the off the shelf Greddy 4-1 style header.

[NemeGuero]

Wasn't knocking it.. just wondering if it exits out the front of the car or if it makes a 180 bend and flips over.

Might just shoot straight down? I dunno seems like its agianst jesus or somthing. Cool though I wanna hear it.

[S13Boosts]

the exhaust manifold does look funny?

[TheJerk]

Supposedly, it bolts up to the exhaust like stock.

[CAP'NZenki]

yea it goes straight down and exits out of the bumper in front of the wheel....theres a vid link to youtube on the 18th post...

[NemeGuero]

I wanna see the rest of the exhaust then

[916S14]

i think that exhaust manifold goes out under the front bumper like all the little drag civics do? Dont know just a though.


Oops didnt see CAP'Nzemki's post. My bad.

[Dutchmalmiss]

Yeah it's a side exit exhaust in front of the wheel. The ease of getting to that oil filter makes me jealous damn it!

EDIT: good god that thing SPITS HOT FIYA LIKE A DRAGON!!!!!!!!!!!

[KA-T_240]

why run SOHC pistons in a DOHC motor. I thought everyone did that in reverse to raise COMP. ratio in the SOHC. Or am I backwards.

[yarou]

That video is sorta way fucking cool.

[wannabe_drifter]

It totally is fucking cool !!!
Sounds like a fun-machine

[NemeGuero]

that video made me happy in the pants.

HOLY SHIT that thing screams

[916S14]

Wouldn't you get more power if you actually ran the exhaust out to the back end of the car?

[240trooper]

TIGHT ! he has youtube vid reving it, sounds nice

[rlpinoy]

crazy ass shit! props man!

[Kn1ves]

like a rocket boost?

as long as it doesnt face oncoming air (it doesnt), its the exact same thing

[ayuaddict]

i think he may be talking about that old back-pressure-adding-power-to-a-certain-extent-theory-argument.

or the heat-assists-exhaust-flow-to-a-certain-extent-theory-argument.

whats that saying...

"beating a dead horse" i believe?

[cdlong]

you're backwards. SOHC pistons + DOHC head = 11:1cr

[irax]

no thats puting a dualcam head on a single cam block

but its close enough.

I'm sure with actual highcomp pistons, shaved head and block, bored, and knife edge crank, distributer-less ignition, electric water pumps, and some more tuning I have no doubt that he will wring 230ish hp out of that thing.

[xamraci]

haha...that video was awesome! Cool setup for sure...Props to him:bigok:

[Koopa Troopa]

If a B16 can make 200 whp in NA why is it such a miracle that a 2.4L 4 cylinder can do it?

[KA-T_240]

If a B16 can make 200 whp in NA why is it such a miracle that a 2.4L 4 cylinder can do it?

From what I under stand, he doesn't have a high compression built motor. I am not a honda guy but b16 CR ratios are above 10:1, and B16 can rev just under 9k stock....

Hey, he's in the 757! :D

That's pretty cool, even cooler after reading his goals for the whole project.

[NemeGuero]

when your car sounds that cool joe, then you can talk shit. hahaha

[bo2o]

that shit rips!

that exhaust is scary tho in the front.
i think if he went a bigger bore and forged he would make alot more power.

hes still unsatisfied about his power band. sounds better then ne turbo car i heard. and was reallie fast. sounds like he hit atleast 7 to 8k rpm

[motorsnail]

Im still wierded out its not pushing more power...Its a duel cam 2.4 and at 200whp? H22 can hit that almost stock with a tune. Not saying the KA isnt a good motor just saying I expected more out of one. Atleast 250 built like this or close to 240whp. Sound cool and the exhaust is cool but I expect more power out of a built 2.4L that is supposed to be a nice motor.

[Healtoeae86]

whats it put on a mustang dyno.

[Killadrifto]

I bet that cars badass in the tight shit!

[240trooper]

gotta remember his compression is on 8.6;1 , throw a stroker kit and bore that shit out it wil be nuts

[motorsnail]

His compression cant be that low.....Unless its on the bottle all the time to get that power. Im calling BS on that compression and 200whp all motor its imposable.

Kinda following the same mind set at this point...my h22a made 195whp with cams, header, test-pipe, exhaust, intake, cam gears, and a few throttle body and IM modifications...and an base tune...

The KA probably has FAIRLY low compression and I wouldnt expect that one to be over 9.0:1

The NON-VTEC(DOHC) F22bs have made 200WHP with A LOT of modifications and serious cams...

[crankshaft]

what did you set your bearing clearances to.

F22 is weak to start though no torque, no potential, no nuffin. I think you could compare h23 and the KA and that power for the Ka still isnt where it should be. Somthing is wrong with the setup, If it was mine I would be disapointed but its not so I should prolly shut up eh?

[wannabe_drifter]

To whoever talked about his compression if you click on the Fresh alloy link you can see what are his mods...

He has sohc pistons in a dohc motor which is supposed to bring compression
to around 10.5:1 - 11.0:1 ...


The fact that the KA doesn't like to make high HP has something to do with its bore and stroke pattern.

I don't know that much about engines but from what I've read the longer the stroke on an engine the more it will make torque but that will compromise the
HP numbers. If the same engine would have a shorter stroke it would make less torque but more HP... (Someone with real knowledge pls fill in or correct me if I'm wrong ...)

the prelude has 87mm bore and 90.7mm stroke (H22A 2000: 200 hp, 156 ft lbs)
the KA has 89mm bore and 96mm stroke (1991 and up KA : 155 hp, 160 ft lbs)

The KA is better for torque with that long of a stroke but not that good in HP for that same reason

So in theory for a higher hp but less torquey (kinda like honda) one would need to destroke a KA, go to 2.3 maybe 2.2 litres but with more ability to rev up and get horse.
(for stock engines the head might also be a factor, I heard a KADE head really doesn't flow that good on the exhaust side and Cams are not that great... )

[irax]

hondas have a slight advantage though, their stroke is small, and they have to rev forever to get those numbers! And FWD has less than 10% power loss due to drivetrain, besides 200 whp on a ka is closer to 240 crank hp. They also got VTEC. Besides this guy hasn't completely maxed on the build so there is more room for growth. I just want to see what can be done with pump gas

the DOHC F22b is almost the same motor as the H23...8crank tq less...its a really common swap out for the H23 in the Si preludes...so its a pretty good motor to make comparisons with the DOHC KA24DE, especially since I have experience with f22b1 sohc vtec, f22b sohc vtec, f22b DOHC, and the H22a...so I am not just speaking out of my ass...

I would say displacement to displacement...the H23 is a better comparison though...

and interesting on the compression...makes sense on the power gains

[kingkilburn]

I think the problem is a mix of intake design and the crank shaft. He should at least upgrade to a fully balanced crank, a stroked crank would be awesome.

isnt it crower that made the fully balanced crank...and there are only like 6 of them out in the world....

[kingkilburn]

Crower has one for sure. I remember reading about AEM looking into a fully balanced and stroked crank but I haven't been able to find any thing about it for months.

haha, my friend has one of the 6 crower cranks...it was like 2300$

[NemeGuero]

Lets not turn this into a Honda vs Nissan thread.

Educate elsewhere, this thread is for the badassness of the ITB'd KA putting 200 to the wheels.

[norcal_black240]

Dont see a 200 whp n/a ka every day. That thing is bad ass

To bad with the money he spent to get 200 whp n/a he could of used it to get like 300 whp+ with a turbo KA. Props to him though with a built n/a KA

[xamraci]

Imgoingtocometoyourhouseandkillyouwhydonttheychang ethemessagelength


the 10hp comment and the message length are both hilarious...mustang dyno FTL

[240sxaddict]

to the people talking about the H22 pushing more HP... its all in the vtec. It's like leaving the KA with stock cams until about 5000rpms and have it switch over to 272's for the top end. honda vtec heads flow very well compared to the KA's.

[turtl631]

It's a lot more than VTEC. If you're running aggressive cams like he is, it'll make the same peak power. VTEC is for low end drivability and fuel economy. It just happens to end up being the best Honda setup for ultimate power because the VTEC engines are the ones that have the best head porting and engine components.

[90KAcoupe]

are honda engine crankshafts fully counterweighted... that would probably explain alot of the power loss. u need to remember the GT3 s13 and s14's make nearly 300whp N/A. and brian crower does make the cranks.. but they are made to order.. u can email him and he will make u one... or he offers a special deal if u can work out a group buy.

[VAs13]

hell yeah, props to greaser and mrd.

[240trooper]

for the compression thing, i had a sohc early 89's came stock with 9.1;1 and after that all ka's we're 8.6;1, im sure with the use of sohc pistions it broght it up ,i dout its 10;1 tho , you guys ever heard of a sohc block with a dohc head? i heard out once aka the compression engine , was like 10.4;1 , havnt heard of anyone doing anything like that latly, and cant remember where i saw it, still that ka is sick

[90KAcoupe]

yea the sohc piston swap does raise the compression. if u compare the pistons u will see why. sohc are close to flat tops, the dohc pistons are dished. the reason the sohc had lower compression was due to the cumbustion chamber shape

[thafriendlypimp]

if i could fab some exhaust like that, it has always been a dream to do a side exit exhaust near the front... that's awesome! I have a concept for an intake like the one he has there, but mine is way "ghetto'er" for budget purposes and lack of real machinist skills... or welding skills lol.

please stop posting this crap. all DOHCs were 9.5:1 and SOHC pistons in a DOHC engine give you over 11:1. i forget the actual specs, but i'd go with greaser on this one, since he actually built the engine, not just talked about it on the internet.

[95KA-Turbo]

His motor has probably closer to 11.5-12:1 compression. KAs are limited in making power because of the bore:stroke and the head doesn't allow for a truely massive cam to be run like SRs or Honda motors. Also, just think of the aftermarket support difference for cams and cam gears for SRs compaired to KAs, there are not companies spending thousands and thousands of dollars engineering cams and cam gears for KAs. Which is why with a lot of money you can make a 230-250whp NA SR "easier" then out of a KA.

Ohh yeah, at the last drift event we were both at everytime he'd go all the babies there would start crying, HAHAHAHA!
