N/A KA24DE
N/A KA24DE
Ok everyone has talked about n/a builds how they cant reach this amount of horsepower or whatever. I am wondering if there is anyone out there that doesnt really have a budget but just took the time to save up the money and do a fully built stroked ka26de? I have looked up alot of stuff on this and kinda have a parts list..... BC 2.6 stroker kit with the race bearings and the 280,000 psi fastners with a 10.5 to 1 comp, .5+mm valves, arp studs, oil pan from excessive, toga hv pump, port and polish, excessive manifold, bc cams 272, adjustable cam sprockets, bc dual springs, 300zx maf and throttle body, spacer, 740cc injectors, nismo fuel pressure reg., 255l/hr fuel pump, ati dampener, 3 piece lightweight pulleys, 11lbs flywheel, stg 4 clutch, one piece 15lbs driveshaft, axle bars, lsd, plasma booster ign., 10mm wires, irdium plugs, dyno tuned. If anyone has done something pretty close to this and taken the time what kind of numbers are you getting? I know its expensive but its all in what you want not what everyone else wants or does.
Re: N/A KA24DE (90's250sx)
I have heard from a few good people that the xcessive manifold is not really the greatest thing for an NA engine. Based on what I have read, I would rather modify a stock manifold than run an xcessive one.
All I'm saying is that I need to see proof that this manifold is better than stock by viewing test results that were obtained by dynoing an engine with a stock manifold and, without changing anything else, test it with the xcessive so that it would be the only variable. I'm not going to assume it is better simply because it is sold on the aftermarket.
One of our members here who does have the stroker kit, BC cams, and the xcessive manifold is Ajax. I think he hit 177whp with some great torque numbers, too. He said it will pull to 7500 rpm if he wants to go that far. In fact, it was in his thread that I read the less than savory things about the xcessive manifold. You can find that thread on his user profile if you want to see it. It is such a cool 240sx, he put alot of time into it.
Liquid Cool also owns a hopped up NA KA. I never asked, but I think I remember him saying that he has 225whp, and with a stock crank. I can't really say exact for his setup, but I would love to know the recipe for it if it's not being kept a secret. Maybe he will enlighten. I looked on his profile and I didn't see any build thread.

Re: N/A KA24DE (seang)
was he running bigger injectors, fuel pump or 300zx throttle body and maf. Did he have his dyno tuned? Cause i find it hard to believe all of what i have listed will just make 200 whp with a dyno tune
Re: N/A KA24DE (seang)
well the Q45 throttle body cause i think 300zx is 5 mm smaller than stock 240? but bigger throttle body and money invested into keeping the heat away with good radiator and dual fans with exhaust heat wrapped. injectors fuel pump and lighter stronger driveshaft parts will free up some horsepower not much but enough and responsivness will be improved
Re: N/A KA24DE (90's250sx)
Here is Ajax's thread. It has multiple pages, as things this cool require more than one puny page. Dyno results are on page three I think. http://www.google.com/url?sa=t...uXApA
Near the end of the last page, I posted a link to a thread from 2005 that a guy got 197whp all motor.

I think 740cc injectors is overkill- you may actually lose some civility because they're made for much higher power ratings.I'm pretty sure that the only people that have broken the 200whp barrier are not using pump gas- at least documented.If you want to go all out, you need to look into ITBs and AEM EMS or similar control. I'm still restricting my power by using a crappy header and piggy-back SAFC NEO.
Re: (Ajax)
yea i noticed that with injectors. what does the stock ka make whp? i want in a n/a build cause i want a car to last with stomping on it and not have to tach it out to make decent numbers and makes your motor life decline drastically. what compression ratio do you have to start running race gas? can you just use a gallon of race gas to mix to boost octane just enough? just an example. i know the motor pretty well but i havent done anything serious. cant you get a throttle body slightly bigger than stock with stock manifold and custom header with yours and push over 200? im starting to think the stock manifold has more potential for n/a then i thought
Re: (Ajax)
well i have kinda thought about just a dry shot of nitrous i think it goes up to 75 shot. i would love to go with pump gas and if i have to maybe a little bit of race gas mixed in. if anyone knows exactly about what the whole compression ratio with pump gas and maybe a little bit of race gas to boost octane for better numbers with nitrous included.
