    turbo 5.3 ls Blow threw carb setup 240sx

    Well i sold my turbo 6cyl out of my 240sx, So i figured I would up grade some cubic inches and see what happens under boost. Im going to start out around 15psi and see how the car responds. Should be a good combo when im done.

    Basic setup: Engine
    2000 5.3 (Stock internals)
    Stock coils
    Gto oilpan
    ls1 carb intake
    Quick fuel Blow threw carb
    MSD stand alone ignition
    tci flex plate (th400)
    Trans Dapt motor mounts
    60mm Precision turbo
    synapse wastegate
    hks bov
    Water intercooler with ice tank and pump


    Transmission:
    Turbo 400 with transbrake
    3500stall
    ratchet shifter

    Hurst line lock
    Rebuilt stock calipers
    New struts with Tein lowering springs (rear modified more)

    I got the fire wall painted



    Had to move the radiator to clear the turbo. built a new support and made new headlight brackets and hood latch bracket.



    Had to notch the frame so the lower radiator hose will fit in the new location.



    Gto oil pan



    Performer carb intake



    specter carb hat



    new fuel pump



    new fpr

    Well I would be a lot further along, but I been waiting on a transmission for a month. I'm getting my money back. I'm thinking about getting a power glide w trans brake now. I think it will fit my setup pretty well. Once I get a trans I can get the motor set in place and get all my little things done.

    i know its a vague question but what is the advantages, if any, of a blow through over efi?

    Ease of using just about any motor for a project car.

    You can make on the spot adjustments with not much need for a laptop or a professional tuner..

    No PCM persay= no SES lights for things that don't need to be on an engine to begin with..

    Partly the reason I went stand alone on the TT build..

    It does'nt need all the extra electronics to operate the engine..

    Then there's also the fact that with a carb the engine bay on a custom is usually much more neat.. No octopus of wire bundles running everywhere..

    Just engine.. As it should be..

    Gonna need some clamps on all the couplers.
    Have you gave the car a name yet? I think Brutus would be a good one. I've seen these cars with LS1s in them. Very beastly. But with an LST....Well that should be a traction challenged queen.....lol These cars are so light weight as it is. I see a 13 second car with a 160 mph trap. You might be 3/4 down the track before it hooks...lol
    It looks great. Can't wait to hear its dyno results. I'm guessing 800s on a light tune.(pump gas)

    Sorry guys its been a min since I've been on here, been trying to finish this project. If all my fuel fittings come in this week I'm going to fire it up this weekend. As for the carb, no lack of tuner, I've always done all my own tuning on the laptop, I'm just tired of injection, wiring is a hassle and seems like there is ALWAYS a problem. + with a carb the engine bay is super clean. I have never ran a blow threw setup, this is my first so its a learning experience for me. As for hp, I won't put down 800 lol, its a BONE stock 5.3, all the way down to the stock rod bolts, I wanna see wat these motors will truly hold, I have heard a lot of stories, on a serious note I think the most I will make is 650 on pump gas. Traction will not be an issue either, I've got the suspension
    Setup pretty well, but will see wat the bumper looks like after a transbrake launch.

    650 is very respectable. Especailly with a light weight, like a 240. Spool time should be a low rpm too.
    The Supra spools around 2300 to 2600 rpm. An LS should be around 1800 or less. Did you lower your compression, or keep the stock size head gaskets?

    Its stock compression, stock head gaskets, I've not touched anything internally, I'm going to start out around 10psi and get a good tune on it, I'm going to keep it a little rich around 12.0-12.4, then ill gradually up the boost to somewere around 15-20psi.

    I would get a meth kit. You want to be very careful of detonation. That is mainly what it is there for. Most of us meth junkies just add more boost. It's about 500 or so for the kit. Plus about $30 to refill a 5 gal container. I used the windshield wash container, because it hold a gal, instead of the 1 pint container that comes with the kit. Depending of your driving habits, 1 gal can last you a week or a month. Since I used the ww reservoir, I have the low fluid light when it is low.

    I am running a water intercooler, so it will have ice in it when I'm at the track making hard passes, shouldn't. Have much issue's with detonation. But ur right it does kill the motors quick.

    Well if you are just running at the track, the IC would be the way to go. I thought you might be terrorizing C6 Z06s on the streets....lol
