its 2013 now, just wanted to see if your guys's idea of 200rwhp is attainable yet
^.^ haha

I like to put it this way since it was brought up again, nothing is impossible.

I made 160hp before throwing the turbo on. You just have to heavily weigh the options on dumping thousands of $$ into an NA motor trying to break 200rwhp VS just cleaning the block up with some extras and turbo'ing it. It's way easier to assist the motor with induction than trying to get it to efficiently suck in enough air by using negative pressure on its own. obviously forced induction is the more efficient way.

yessir i did

Derek Greaser from Millenium Racing Development in Virginia achieved 198-203whp (I can't recall which, although I believe it was over 200). He used gsxr converted itb's, his own custom header that was side exit, cams, and 11:1. This was in an s13 that he threw together to experiment drifting with fwiw.

Greaser's KA was ridiculous.

Any links to more info or videos of this car? I'd be interested to see it. And to hear what it sounds like.

You dont have nearly enough money to even get close to record numbers on a KA. it honestly not that impressive IMHO. To even get close to 180-200whp you need aggressive cams built head block(high comp pistons) aggressive port and polishing including matching of all intake and exhaust ports, a good set of LT headers, and engine needs to be properly balanced so you can take advantage of the increased revs etc etc etc waste of time and kind of stupid. O look I got a N/A ka that makes 200whp, guess what it still runs 14's and is still slow compared to even regular cars.

my last na build i did was about 6 years ago. it made decent power. but in order to get that power i had to.

ram air intake, knife edged the throttle butterfly, ported and polished the intake manifold, gasket matched, 91 exhaust cams, decked head, ported and polish the head, had some crazy valve work done. gasket matched, ported and polished a custom 4 to 1 long tube header. that collected into a 2.5 inch exhaust. theres more but i cant remember. stock pistons, balanced rods and crank. i cant remember if i used 89 flat pistons or not. i had a flywheel reworked and balanced. stock clutch(stupid me) crappy open diff.

the ignition system, msd all the way around. timing was set to what ever got me the best throttle response. iridium plugs and some thick wires (cant remember the size)

the fuel. adjustable nismo fpr usually maxed out. this is the area i started running out of money. so i put a sr20 maf on it to make everything super rich and it showed a difference. better power curve and seemed to pull harder, and shitty gas mileage.

over all characteristics of this build was a real snappy response. though i didnt care but it turned out to be very reliable. it pulled hard from 2500 rpm to about 5500 rpm. never had it dynoed or 1/4 mile. but it would do a easy 0 to 60 in 4.9 to 5.1 on avg. i raced cars that pulled high 13's to low 14's and usually won. (not sure if it was my car or their driving, but a win is a win)

final thoughts. there wasnt alot more to do to get power out of it besides oversizing the pistons and stroking it. it was a fun build and left alot of people wondering wtf just happen. but when it comes down to it. it is far..............i mean far easier and cheaper to slap a S/C, turbo, or n2o and get the same results. if i had to guess this made about 200 ish AT MOST(this is laughable by todays standards). when you think about the thousands of dollars needed to make n/a power. you could get a rb20, rb25, rb26, sr20, ka-t, ka-s, ls, or any number of the motors that swap in.

conclusion, this was my first and last n/a build. if you want more then 170 hp from a n/a. you will have to open up the motor and start pouring cash into. so consider what you want out of it, over all. then pick the best route.

feeling a little necrophilia here, but trolling this N/A hp thread was good enough, but I had to post just because...

Rebuilding your KA will cost around $1600 IF YOU DO THE WORK on the block, and add $500 to the machine shop for align bore and hone.
Add another $300 for rebuilding the head right
Add $600 for cams
and $65 an hour labor for Nisstune work

At best as you can see you will net around 220hp, but for a streetable car, that is seriously fun DD stuff. Of course you can go 14:1 compression, radical cams and hit 250hp, but you'll run up people's asses, won;t be able to drive parking lots for shit, kinda like a kid in a new RB swap who never drove a multipuck clutched car.

Yeah, I came here to look and perv on this thread because my zenki and the kid's kouki need rebuilding so NA 200+/-hp sounds good
