ok so i want to build a ka/na.i don't want to make it a drift slut i just want to get it side ways here and there.it's my daily driver and i can't afford to fuck it up.i want to get as much power out of it without touching the head..the furthest i'll go would be cams.so what do you guys/girls reccomend i do....let me know any mod that has given you noticible extra power.
 
with out taking the engine apart and increasing the compression porting the head and changing cams you are not going to gain much power from bolt on's. Unless you consider a turbo kit a bolt on performance option.
 
the amount of machine work necessary would cost the price of an sr and then you wouldnt make any more power. get an sr20 and turn up the boost. Modifying aftermarket headers to accept a 3in collector, smaller clutch assembly to lighten the drive train. 1peice aluminum drive shaft.

its going to be even harder to make the maximum power on 93 octane. I dont think you want to run 100 everywhere you go if you want the power.

The extensive blueprinting work that has to be done to extract every little bit of power is $$$$$ and using aluminum connecting rods requires you to rebuild\check the engine frequently.

just a few things the machinist has to do in preparation are :

check the line bore
magnaflux the crank and block
index the crank shaft
knife edge the crank
micropolish the crank
rebalance the crank shaft
balance the connecting rods and pistons
chamfer the main and rod oil passages
bore and rehone block .40 over
redeck the block
check thrust clearance

This is just the bottom end preparation, not even assembly. The list gets ALOT longer when I add in assembly procedures and the necessary head work.


The things that i listed above need to be done by a highly qualified professional with time and patience who costs alot of money.

XS Engineering uses dynapacks. Dynapacks read very low. When splitting hairs with power levels is so important, so should be consistancy - same dyno, same day. Either way, even comparing to a "stock SR" is a waste considering a home made boost controller could give the stock SR another 30whp. Add and Exhaust + FMIC and you can have almost 100whp more than that NA KA. KA's are cool but for cheap power, a factory turbo'd car pwn's.
 
SR has the ability to give you more power. an engine that comes stock turbo is gonna fufill your needs more than a NA engine. then youre stuck w a blown motor. boo. no one wants a b lown motor

comparing it to a stock SR is not a waste. the guy made the same power as a SR for 1000!!!. If thats all the power you want then why waste an extra 1500+ for a SR swap?

don't waste your time, just drop in a sr, and call it a day

or boost the KA, ive seen someone run a 13.7 w/ a 800 KA-T.

Your response is just riddled w/ opinions, so im not even going to bother. Ill say just one thing, Turbo doesnt have shiz on the throttle response of N/A

I disagree. That KA on XS's dynapack would make less whp and $10 homemade mbc could up the SR's power by 30+whp.
 
its a fine line between n/a and turbos man, i have see some turbos be just as responsive as n/a cars... n/a's are fun but only if you go all out on then and that = not cheap. i have also seen turbo cars that literally have the same response as n/a cars. i mean n/a cars will take the cup for best response but if you can get a turbo to do the same with minimal loss then there is no point in wasting money on building an n/a car that will barely see the track.
 
Why do you want more power? Aren't you happy with what the KA gives you? Just add some minor mods like crank pullie, light flywheel, intake, headers and exhaust and that should be fun enough. In my opinion what makes a car fun to drive is the way it handles, i prefer to drive a lotus elise before driving a 1000 HP dragster. But if you want so much power just get a SR, and sell me your KA

You still dont get it. You're argument is using points that dont warrant any merit.

$1000 = 204 chp n/a KA

$x(1500-2500) = 205 chp completely stock SR.

once we get beyond the 205 chp point, then you can argue all the FMIC, MBC, boost points you have. But were talking about a certain power output. And because were talking about a certain power output, only certain facts can be used.

Blah to all of it, if I was this guy id find a spare KA for dirt cheap and put together a cheap turbo kit.
 
Oh I get it, thanks. But if we're only talking about reaching a certain power output, why did you bring up a comparison to stock SR's? Anyway, here's what you don't get - I don't doubt that an NA KA with bolt ons is making 170 whp nor do I really care. But when you're using a dyno chart from a different dyno as the means of a comparison like they are, I'm going to point out the problems. Oh and all this guesswork flywheel horespower number stuffs is weak. Here's why: those guys are adding 15% to their dyno to come up with their hp numbers. OK, well the SR's peak was 168whp which, with their math = 193 hp. Wait, something's wrong - or maybe Nissan lies. SR's supposedly come with 205hp. OK, so now we know that the dyno loss should be closer to 22%, not 15%. So that means that KA really has 207 and we haven't even added the made up numbers that a cat removal and intake would make!!! Anyway, post a dyno, show resuts, be happy.
 
I had a NA/KA and it cost a lot to be reliable and beat on non-stop hitting the rev-limiter at drift events and street sliding.. if you wanted to make the motor for something other than drifting, then i guess it could be cheaper, but you will prolly get 20-30whp lucky if you do cams, underdrive pulley, headers, intake, exhaust, plugs, plug wires, flywheel, driveshaft but that is a little over 1300$ for 180hp when you can pay 1600$ and make 220whp with a motor that comes with oil squirters and a better exhaust note lol

THis comming from a guy who told me that if I was to drift his car to keep the revs down since he didnt have rocker arm stoppers yet

well the sr doesnt have any valvetrain work like my KA did lol
 
Rocker arm stoppers don't do shit. Rev the piss out of your engine. If you really want to help your valve train, get good springs and retainers and bounce off the rev limiter all day.
