Future plans na ka? sr20de? ka-t?

[SlappieBooBoo]

Ok so I was thinking today about what route I wanted to take in terms of my motor and how I will build it. I was wondering what it would take to put down 200rwhp from an na ka. I have seen a post where some one was putting down 169 with cams, a pulley, 3in exhaust, an intake, and tuning. I was wondering if you added ITB's highercompression pistons and a new tune could you hit 200? What would it take to reach that mark. As for sr20de's just wondering how much they put down when built....i guess i'll search that one. Still i dunno what route i want to take. NA ka would be my first choice. but i'm wondering if it would be worth it.

Why? For as much money your gonna throw in to a na KA to make 200 whp, you can get 400whp on a KA-T or SR20det. Just my 2 cents...

[OptionZero]

look in the frickin tech forum, there are FAQS for all the major engine options

[Realchaos1]

KA-T's can reach rediculous numbers that the SR has hard times achieving.

But the SR is lighter then a KA-T, and can be build to rev to the moon with significant boost.

If I had money, I'd invest 10,000$+ into an SR (excluding the cost of a front clip)

[trsilvias13]

go buy a sohc built by robello they have ka that makes like 240whp or something like that. It is the only na ka option I would go with. Otherwise turbo your car or do some crazy swap like a ls1 or ls2 or vq or whatever motor float your boat

[SlappieBooBoo]

cool so far no bashers.
i realllly want a na ka just becuase it seems like it would be a funn ass car to drive.
i'm not tryin to race anyone so peak hp isn't really of concern
i want a super responisive torquey daily driver not a fast n furious drag car.
i don't see a need for more than 200rwhp in my daily
i have done research and it seems that its qutie tought to get near 200 hp on an na ka

[Realchaos1]

what would be nice is an N/A KA that could rev higher then 10,000 (what i have heard, with the 96mm stroke it is impossible), but people can dream. :]

[Ricks15]

I heard about this a while back on the fourm there is a company called Ventura racing that had KA's that were fully built to "300-400HP" and those engines were for SCCA racing. But yeah im with you on that idea id like to have a KA with more balls but yet still kepping it for daily but man parts do add up and so does installation.

good luck.

[fliprayzin240sx]

Talk to Bory (infinitexsound) hes dealt with race engine NA KAs. iono like i said to be, for as much money your gonna have to spend to get a KA to make 200 hp, you can make a better setup for less price and more power.

[Omarius Maximus]

Your not gonna have a torquey KA when its making 200rwhp also. All the low end will probably be non existant after you start going into the head and cams etc. As far as a daily driver, it would probably suck big ass. A turbo amplifies a KA's positive traits whereas going high power NA will change the motors characteristics altogether.

you can see this has been covered before... :squint:

[SochBAT]

First and Foremost, what are you using your car for? (if you've already answered, kudos, i thought your initial post was kinda long and dragged on)

Me and bory used to talk about my dreams of grandeur with the SOHC KA, whether it was NA or T. Regardless, SOHCS are strong as hell, and can put down heavy numbers in the DIY turboform (VenturaRacing achieved ~770hp iirc on a SOHC KAT, whereas DOHCs are barely hitting 600). Regardless of choice, each has a fairly big background in motorsports, so it shouldn't be a problem getting high, usable power. Then again, if you've got limitless pockets, the sky is the limit. And then again, power doesn't run on hopes and dreams.

A Naturally Aspirated RB engine would be fun.

[P4rD0nM3]

How come RB is not an option for u? Or other engines?

An N/A ka reving to 7.5k and cams where power started at 7k. running on alcohol, with a flat spot in the tuning and ITB's (the only mods were cams/intake/exhaust/tuning)

Put out 225crank hp.

SR's are not built for reving.

KA's have a better head/intake design.

And turbo's kill my daily driving funds hardcore :).

[SlappieBooBoo]

Yeah I searched somemore and got some more info. Sounds like getting a KA to 200rwhp with no forced induction would be a huge pain n the ass and i don't have endless pockets so i was curious to see how close to 200rwhp you could get with out havng to do anything MAJOR

that car is making 200chp, not 200whp.

[tre]

I'll dyno my car shortly and show you what i got out of intake/header/exhaust/cam sprockets/tuning.

then you can decide what to do.

but atm my power band goes from 4200/4300 to 6000/6100

theres this guy on club 240 named bigvinnie who only spent about $1000 and got like 195 to the wheel.

Wooot woot....200 CRANK HP...wuts that like 160 whp?!?! :keke: I mean come on, ive seen NA KA make 140 whp on an exhaust, intake and header. Wanna explain to me how this is special vanish cuz i still dont see it. Do more research and see how many NA KAs out there actually have hit the 200WHP domain, theres some but not alot. If you can hit up japan, theres more 200whp NA SR20, only reason the SRs are more capable of hitting that much HP NA is cuz you can MAKE them rev to the moon and back. So yah get back to me with that one vanish but till then...STFU!!! :keke:

[SochBAT]

Cmon now, you know KAs are all about TQ!

USDM POWER!! :keke:

SOHC, nothing else.

As with any serious NA setup, you lose the ability to have a reliable daily driver.

Fixed.

[alexchanman]

F all that noise, get a CA. 10k revving monster.

[tre]

Sad to say the cheapest bang for the buck with the KA is SOHC pistons in a DOHC. Raises compressions. I thought it was a bad idea till my dad's friend who races these engines use to do that HAHA

So lets see.....a guy makes the same hp as a STOCK sr20 out of N/A KA and $1000. Hmmmmm...if he was to include pistons, do some head work, rods and crank, rocker arm stoppers, the general treatment; then he would pushing much more then 175.

And its only a 15% degredation drivetrain loss, which would put it at 175 not 160..geez.

$1000 for 204 hp, im game.

I hate people that don't read the whole thread or the links posted before posting...

Awh yes I'll take credit where credit is due. That RWHP is a little over exagerated and I didn't say that I made that much. I'm pulling a little under 175RWHP, which if you break down drive train degredation is a little over 205HP at the flywheel. That is the same (or close equivelant) HP output as an SR20det on stock 7psi, I stated it very clearly in that thread I started. I stated on fact based opinion that you can swap an sr20det with stock 7psi and no other mods for a little under 3grand(in another thread) in time/labor, or pretty much add $1000 in bolt ons and ecu tuning to the KA for the same achievable power output.
Sr does have an advantage that it can boost with a stock T25 to a little under 15PSI with stock injection, putting it to about 225RWHP with under $400 in other needed parts.
I'm defenitely not going to turn this into a KA VS. SR debate those threads always go NO WHERE.

Just for future reference.
STock SR20det on 7PSI.

Both graphs slapped together, as you can see both engine make peak power at about the same RPM, SR can just drag a loss in power longer.
KA has a much smoother torque band.

Wait there is no way that putting SOCH pistons in a DOCH would work would it?? is this safe to do?

Dude search... Yes SOHC pistons work to raise compression.
Research the difference between Pentroof head design engines, and hemispherical head design engines. Then put the knowledge together and see why it works. Now go read a book...
