My neighboor is selling his 1990 240 sx, manual, almost no rust and half the parts already replaced, with the abundance of after market parts i will most likely take it off his hands in a heart beat.
until he told me he had the ka24 motor ( not sure which modification of the ka... will check later)
now i'm not dissin the NA community or anything, but it clearly hit me that 2.4 L is a little to big for a turbo car, and i'm a turbo junkie.
Now, i'm completly new to any motors bigger than 2 liters that are not a v6, so what sort of potential am i looking for?
His car has 240 000 killometers on it, so i am planning on yanking the engine out and completly re-building it. I am also prepared to invest 3 ( TOPS FOUR) grand canadian into the re-building of the motor ( still need money for the body kit + rust removal)
So what i'm asking for is a 1) a list of parts2) pro's and cons of owning a high-displacment four banger3) whats the gas miliage? ( or kilomitrage...)4) is there ANY hopes for a turbo/supercharger?5) can i hit 250 - 300 crank hp with proper tunning6) i can get a stand-alone mgmnt system, would that be a plus?
and so fourth, as much information about the ka24 as humanly possible, and plz no re-directs, i know the sr20 is popular but i cant get my hands on one.
.. and if the ka24 turns out to be a drag... ^_^ i can always dump a b18 into my civic, muahaahah....
alright please as much info as possible, MAINLY REALISTIC POTENTIAL OF THE KA24. thank you
New to the scene, need the ka24 explained.

Welcome to nico... But let that big red button up to the top right guide you on your quests.
Every one of those questions has been answered before.
If you have specific questions (not easilly searchable either hehe), not generalized like this list feel free to ask.
See Im not always rude...
btw I for one, would never steer one towards an sr. In your case (plan on forced induction) a KA24DE as a base motor to build from (btw 350 down daily driven on stock internals has been reached via FI from the DE motor and precision tuning), as all 89-90's had sohc KA's, but not an sr hehe,

more displacement = more air through the motor. more air + more fuel = more power.
That said, a properly sized turbo will accentuate the strength of any motor's power band. Ther eare plenty of 240sx owners running turbos. I run one and it's great. I will say, I know of no kits available for the SOHC KA yet. I'd swap to a DOHC version first if you plan to rebuild. There are kits available for the DOHC version.
As far as the Civic with a B18, consider, you may get about a 50 HP increase depending on what motor you started with. Typical KA turbo with a relatively mild 7 psi have seen about 100 HP increases. Sometimes more. And as 96_S14_SE said, 350HP at the wheels has been seen on stock bottom ends. And those were at about 15 psi.

well first engine that comes to mind as large displacement and turbo is a grand national for me. I assumed he meant V6 NA because if he was familiar with V6 turbo he would know that displacement makes little difference in effectively turbocharging it.I wasnt going to trash talk...but oh well...FYI: VH45DETT isnt a word

uhm, no motor is "too big" to use a turbo. seen that new benz...?7thGear wrote:now i'm not dissin the NA community or anything, but it clearly hit me that 2.4 L is a little to big for a turbo car, and i'm a turbo junkie.
2. cons of this motor (as compared to smaller-displacement fours i've owned) - more vibration, and it doesn't like to rev like my other car- after owning a '95 base and now a '91 base coupe for a few months, what it needs (IMO) is hotter cam(s), longer rods, shorter final drive, better flow numbers from the head, and less accessory drag. (these mods might not all work in your favor if you do end up going turbo, but you'll notice this is the "all motor" forum, so i'm answering the question in that context.) pros- it has almost as much torque and hp as my old VR6's did, in a car a few hundred pounds lighter, and it's RWD; 'nuff said.
3. if you beat on it, you'll go through a tank quickly. drive sedately and it's about as good as your average 4-cyl camry/accord.
4. for turbo kits, go to http://www.realnissan.com/ ; i don't know of anything else kit-like for the single-cam - for supercharger, you'll need to DIY; and my $.02 on that subject is avoid roots, lysholm/centrifugal are ok.
5. in all-motor trim, you might hit 250 crank hp if you have someone really good build your engine for you- but i don't see that (and the rest of the stuff you'd need to do to the car to complement it) happening for $4k CDN. for turbo, go look at a few of the topics in the turbo ka forum.
6. not yet. :pface

FIRST OFF THE BIGGEST DISPLACEMENT TURBO MOTOR THAT IS SOMEWHAT AFFORDABLE IS A CYCLONE/TYPHOON WITH A 4.3 LITRE V6 WITH A T4. SECOND OFF LISTEN TO DK REALNISSAN HAS 9SEC SOHC KA'S AND THIRD DON'T WASTE YOUR TIME WITH A TRENDY B18C GET A J SPEC H22A AND THEN THROW A TURBO ON IT AND SEE WHICH ONES FASTER
