[quote=from links page]-230HP NA 240SX? - Good site. 230rwhp? That's near impossible for the NA KA engine


does anyone have a copy of this page? i would like to look at it but the link does not work and i don't know who submited it

I thought this thread was about my old car for a sec. &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/biggrin.gif" border="0" valign="absmiddle" alt=':D'>
Nissan was close to releasing a production KA putting out 200HP so im sure it wasn't that impossible

you could probly hit 230 flywheel with a good enough engine rebuild with high compression, pistons, rings, cams, etc... but i dont know anything about this car.

That link has been dead for about 8 months now <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

To get 230rwhp n/a you could have spent less money for a more reliable turbo pushing 250++rwhp. &nbsp;Though you didn't say you were going to try it...I just thought I'd add that in.

244 bhp is very possible with the SOHC:

244hp NA from the same engine running a turbo to get 244hp will have MUCH better response, and end up being a much better cornering machine because of it.

at a meet, there was a guy putting 200hp @ the wheels on a SOHC

I won't argue with that. Given the same HP and TQ I'd take n/a over turbo in a heartbeat. You just can't beat the n/a's predictability and throttle response.
Like someone said (probably you ace), there would be nothing worse than your turbo kicking in through a corner. &nbsp;The sudden jolt in power would send you spinning if you were anywhere near the car's cornering limits.

But I stand by what I said in that with turbo you can get more HP for less $$.

The question was whether it was possible to get the KA past 230hp though.... &nbsp;and you can get a KA up to 300hp if you've got money and don't mind having a pretty race-only engine <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/tounge.gif" border="0" valign="absmiddle" alt=':p'>

Nismo perhaps?? &nbsp;
Courtesy Nissan lists a twin carb setup under nismo/s13 (http://www.courtesyparts.com/nismo/s13/s13_2.html). &nbsp;I'm pretty sure this is the setup that uses individual Mikuni throttle bodies.

i believe the throttle body is part of the intake before the air goes into the intake ports...if you have one for each cylinder youll get more airflow and efficiency

It uses Mikuni carburetors... but a twin carb manifold is easily converted to EFI. I know TWM Induction makes throttle bodies with injector bosses built in that are designed to bolt up to Weber manifolds, they probably make a set for Mikuni manifolds. If they don't, someone else does.

EDIT: TWM Series 2900 (http://www.twminduction.com/ThrottleBody/ThrottleBody2900.html) throttle bodies are indeed a bolt-on replacement for the Mikuni 44mm PHH series carburetor.

You could also make your own by cutting off a stock intake manifold right after the injectors and welding on flanges for throttle bodies of some sort. This would be the only option for a DOHC KA, as the Nismo carb manifold only fits the SOHC.

It's a little annoying that the SOHC seems to have more neat stuff available to it... the DOHC head is more attractive for a streetable buildup.

Wouldn't this allow the air going into each cylinder to be inconsistent?

Having individual throttle bodies for each cylinder wouldn't mean that the airflow to each would be inconsistent. The R34 (I think) has one per cylinder and theres no problems.

zephyr
05-23-2002, 12:36 PM
i know one of the key upgrades in the e46 m3 compared to the e36 is that there is one throttle body per cylinder, i dunno how much this contributed to the 30 hp increase or whatever it was, but im sure it was fairly significant. &nbsp;Definitely can't be a bad thing to do...

mistert
05-23-2002, 02:32 PM
actually, its a 100hp increase from USDM e36 to e46, and though there is a change to individual throttle bodies, the increase if mainly because it is a completely different engine in place of the old one
