    Need help about KA24DE

    Hey guy, i was wondering if any of you guys know what's the best FI option for me.
    after joining a few off-road trips i started liking hanging in the jungle and stuff like that.
    first I needed a ride which is Nissan Roniz and I'm sure you don't know what it is.
    it's based on mark 1 Xterra and it has KA24DE, the same engine you can find in a 240SX.
    the car is pretty good in off-road but it suffers from a weak engine, so i thought maybe a blower might help me on that, something not crazy and on bodget.
    thanks

    There are a ton of people who mod the 240SX so you should have plenty of options. It just depends how far you want to go with it and your budget.

    they are a ton of people who mod 240SX, yes but a few of them went for SC.
    and it seems Eaton M62 is the only available choice.

    What is wrong with that? The M62 is a positive displacement, should give you what you are looking for.

    Yes, it's all about low-end and a positive displacement can do the job perfectly, but i was looking for more options.
    i don't like to be tied up with just 1 choice.

    That really is your best choice. It's tried, it's true, it's cheap, go for it!

    Drop in a built SR20DET (you can hit 400whp stock internals too), or build all the internals in the KA and tap a spot to run a oil line to a turbo.

    Sounds cool but I don't want to hit the track and break records, just something with more power so i can do better in hills. i want something with a good low end response, I don't even consider a centri as on option and turbo is exactly opposite of what I'm looking for.

    You know what the peak torque rating is of the new BMW 4 pot? 1250RPM.

    Turbos don't have to be laggy, it will help you pull out of spots because load makes it spool, not engine rpm, and they will always have better efficiency. Your truck with a small, twin-scroll turbo @ lets say 10psi, and a 10:0 or higher comp ratio will have virtually NO lag, and be able to build torque at very low engine speeds.

    The posi super would be cool too, but overall you will make less torque vs a similar sized turbo system. At that point you would be trading torque/power for throttle response.

    It's getting interesting.
    so in your mind how much it cost to put something like that together ? another reason i'm looking for a positive displacement is price, those things are really cheap compared to other setups.

    And it should be reliable, i don't want to be stuck in a middle of desert with a focked up turbo, is it possible to get something not laggy and reliable with low budget?

    What happens when you are in the desert with a f*cked up supercharger, or burnt valves, or a broken belt, or dead bearings from detonation?

    It all depends on the kit.

    Please post a link to what you are looking at and I will give you an honest opinion. BTW, intercooled turbo kits usually have lower IATs than non-intercooled blowers.

    thanks man for trying to help me, it's really appreciated.
    M62 is just bulletproof, at least i won't worry about supercharger failure.
    finding a link is my first problem, there are FI Xterra's out there, many but most of them are 3.3 V6 not 2.4 I4.
    there are two 240SX guys with M62 setup, but their write up is pretty bad and it won't help you.
    i think I'm the first one with this setup.

    So it's just a roots type?

    I wouldn't do it. You won't gain much power, but lots of heat. I wouldn't get anything from Eaton unless it was TVS. Plus you'll have to fab up a bracket and belt system with a different crank pulley. Call some performance shops, they can point out the weak points and find you a solution.

    Full-Race happens to work on lots of SR20s and KAs, maybe call them first? http://www.full-race.com/

    Yeah, I've heard about the heat problem, that's the only thing that stopped me from buying it before.
    Thanks about the link, time to shoot some e-mails.

    An Easton M62 is exactly what he needs.

    Yeah, to heat soak his motor and make like an extra 30 to the wheels....

    Roots suck, period. I'd much rather see him put a TVS and some nice injectors.

    Roots do suck but at low boost they are fairly efficient. For a TVS he would need to run more boost to get greater efficiency than the roots and that won't be possible on stock internals. With a decent intercooler he will be fine, it's the way to go for him.

    Keep the KA and turbo it. It is just as strong as an SR20, and had less issues. SR's have oiling issues. It's cheap and easy. My friend is building one as we speak.
