i was gonna post this in the na section but that IA'S honda club.
NA 240sx
just wanna see some na 240sx owner's mods and some hp and torque numbers.
i was gonna post this in the na section but that IA'S honda club.
you can also go down to the Nissan section.beautiful 240, my fav model year.
The Carbon Fibered R6
it is better to be turbo on 240s.
I read an article on a s13 with intake and exhaust that has 127whp.
yea i gotta cheapo cold air intake. sounds really good but slow as hell. hmmm sr this summer i guess.
I've never heard of a na ka with power to match the price.
although if u buy an sr its really spending 2k$ for 50hp. the sr is just an easier platform to build higer numbers from safely.
400whp potential
easily. big turbo (gt2871r, etc), 550cc injectors, tune. and a couple other bolt ons.
400whp is about the limit for stock
It is hard to break 200whp on a na DOHC KA. I read a thread on Freshalloy with a guy that had intake, headers, exhaust, port and polish, cam and pullies and I think he had like 201 WHP.
There are only a few people that brake the 200whp mark with a KA. You will most likely have to rebuild the whole motor with everything aftermarket. The engine puts down about 135whp on the dyno. So I,H,E combo would put you to about 155 I would say. Then cams and a tune would do to 165-180 depends on the cam and the tune. Last would be pistons, headgasket to raise the compression. Then if you are lucky, you would reach 200whp. With all these work, I would say a basic turbo kit, which put you way over 200whp, then rebuild engine for 300+. of course tuning every time after the mod.
We gpt to meet sometime cause we both drive red S14.
My S13 did 133 to the wheels with a hacked airbox and an exhaust. woohoo

i never heard of a na ka gettin 200 to the wheels. just to the flywheel.
very rarely do you find good NA 240's what are you going for is the first quesiton you need ask yourself.
You know better; next time will be a ban.
specs on car^
it is not a na ka.
Edit: i cant read. i thought it said 280 whp. i was like BS
It would be in your best interest to do an sr20 swap.
Or at least boost the ka.
NA just isn't where the power is at with 4cyl.
ok so if i wanted to get a sr. my car is a 96 so its obd2. im screwed for emissions right?
There are ways around it. register in a different county.
obd2 emissions are the hardest cause you cant clean pipe it, not that i condone illegal activities or anything
na sohc motors can be beast, the dohc can be ok. there is a 240 with 170,000 miles on motor (ka24de) with ecu,header,intake,exaust and a tune that made 180 whp which is pretty good
Buy a E and swap it in, better NA platform.........and if someone puts lol or thinks I am kidding, lol at you noob.
agreed.
...btw a 250whp KA24E NA is not unheard of outside the "box"
About how many pounds of boost would it take to reach numbers like that?Originally Posted by Andyc3020
done some more reading....basically since my car is obd2 the only thing i can do is the greddy turbokit without the intercooler.
makes me wish my car was older. somebody please correct me if im wrong about the whole obd2 turbo thing.
Get rid of the OBD2 then, and you can do more then just a Greddy kit.
S14 yay! NA KA ALL DAY
Why not the Intercooler?
i really need a diagram with how the egr system works i guess. from what i can see the only difference i can see with the greddy kit as opposed to other kits is the fact that it doesnt have an intercooler. so i was thinkin that maybe the way u have to pipe the intercooler affects how or where the egr goes in the exhaust. help me out here i dont have any idea what im talkin about.
somebody wanna explain how an egr works?
Dude just do what ever you want to the car and pay a little extra for emissions.
i kinda wanna avoid that if at all possible. i just want like 250-300whp reliably.
Well good luck to you then, obd2 is gonna be a pain to work with.
what makes the greddy kit legal?
They pay the kit to become legal. Too lazy to get into details.
I do not think the intercooler has anything to do with the EGR. I do not know how exactly it works, but I think it goes somewhere from the exhaust back to the intake. So the worst situation is to tap a hole to the intake piping. From most of the turbo car I have seen, the EGR goes after the MAF, before the turbo so the only thing you have to worry about is if the pipings get into the way where the EGR is (I could be wrong).
The easiest way to put a intercooler is to cut the longest straight piping from the kit (probably at the front), then put an intercooler there. It may be small, be it is an intercooler.
Most Greddy kits dont have a intercooler, you can simply add one though. Buy a eBay one with the piping and fab it up, easy.
The greddy kit is CARB approved. that is just for california. in georgia as long as you pass emesions your fine, theres not inspections. so you dont have to get the greddy kit for it to be legal.
Get a P.O. Box in a different county and use it on the registration.
Problem solved.
BUY MY HATCH <--click the link, cuz.
just put a b16 in it
Or D15B1
The technical advancements and breakthroughs in modding NA KA has been so slow, there's always talk, but Greaser's build is one of the few that's been documented so well and thoroughly. There's still some left on the table I bet.
I don't think the Greddy kit actually has the CARB exemption. If you're OBD2 and want a turbo KA it might not be too hard. Keep all your emissions equipment, mainly you'll need to keep the stock ECU (meaning you'll need to tune with a piggy back) and the EGR bung on the exhaust manifold (you can go custom mani, but I think Greddy is the only off the shelf solution). If I remember correctly the Greddy mani keeps the stock main catalytic converter (on the stock down pipe) so that won't be a problem. It has nothing to do w/ whether or not you run an intercooler, it has everything to do with the Greddy manifold having a provision for the EGR and keeping the stock main catalytic converter. It's still technically illegal, but I'd imagine in a state like Ga as long as your OBD2 read out is ok (and it should be with a good tune) you will be fine, I've never been to an emissions place in Ga where they cared more than the OBD2 read out.
The problem with the Greddy kit (and you can find alot more about it on some 240 specific forums) is that it's just appears to be hastily thrown together, many have experienced boost creep when they replaced the factory down pipe, heck there's a metal restrictor plate thing welded in the intake, how Greddy decided to put one there I don't know. Good luck.
Please tell me if you think my car looks good. But don't tell me if you think it's ugly - only on IA
