heyy guys is it possible to build a 1990 KA24E sohc engine to obtain 200whp? I kno that would require lots of bolt-ons and stuff … Im guessing u cud use the dohc head with sohc pistons as a start for a higher compression (increases to 11.1:1 i believe correct me if im wrong) and then what? better injectors? timing? camshafts? ECU? MAF? throttle body? headers? exhaust?
you can do anything if you throw enough money at it.
high comp
ITB’s
cam
would be awesomely fun to drive.
There is a guy on Zilvia that is making 350whp on a N/A KA24E IIRC
He fabricated his own custom ITB’s and throttle body. There’s a whole 4 page write up on it and such if your interested. Just search “ITB’s” or “N/A KA”
Doooo it
Ummm I bleieve he hit JUST over 200hp N/A… Not 350hp (These aren’t Honda’s K-series)… If you can find the link… please prove me wrong.
yeah ive never heard of a 350whp na ka24e…link please
Yeah highest I’ve seen is 230ish for a KA24E. Note though, those things rev like honda B series.
The guy on Zilvia/FA is just around 210-220 I believe. He’s shooting for more though, and it sounds unreal. Good luck making a streetable motor like that.
well ive been thinking about that idea for a while now … but what would be better to do … have a sohc block with a dohc head or grab a ka24de engine n replace the pistons with ka24e pistons? id love to have my engine go 200-210 Max … how much would u guys think it wud cost for something like that?
I would love to see the look on an SRer’s face when he gets spanked by that thing…
i bet that 240 drives insane eh 
f*kin RITE! its nice to be different and have somethin that not a lot of ppl do … sr’s are good but i wudnt want to put the money down on one :S fuk that …i already have an engine which has good capabilities for hp gains with the proper bolt ons … i wonder how it would sound like? how it wud feel
check this youtube video of a 240sx running the quarter mile in 11secs on a NA KA24DE 
Holy shit check this vid out of an ITB KA 240 LMFAO! Nice!
We definitely need a link to that so it’s easier rather than searching thru the zilvia forums…ain’t a member yet lol
Yea, I was wrong. He was making about 155hp. Here is the link.

And apparently the new record is 217whp on a N/A KA. The link is also here.
sucks man, cant access the second link

instead of having ITB’s, can u go thru a shorter route like having ur block ported and polished, headers, camshafts, jwt ecu, higher compression (like forged pistons), intake, flywheel, steel/aluminum driveshaft all on a KA24e?
You still need ITBs if you wanna hit those numbers. It’s a very heavy build to get that power out of a KA.
if you have the money, go for it…if you are on ny sort of budget, just go SR… more power, for less money
