    Ok so my truck has an 18rc that is the original motor. It gets around no problem very smothe actually but Of course me as the person I am I like going fast. So a buddy of mine has a 5.7 ls he wants to sell me. Getting to the point has anyone seen or had experience fitting one of these in this little truck?

    I thought about it and researched the wiring and everything. Seems like a somewhat simple swap if you know your way around. Lol. Biggest problem youll probably have is frame with up front. If you can afford it, jump on it and start a build thread.

    I guarantee itl open the door for more guys to do this swap

    Nice! That's my long term goal. LS swap and a 6 speed Manuel. Go for it, then I can just copy your build haha.

    For sure I'll have lots of pics. I've seen a guy do a stand alone wire harness that I'ma probably go with. The only thing is the motor mounts wether or not I have to fab them or I can just order.

    the 6 speed was exactly what I was thinking a local guy has a t56 that would fit nicely.

    I have heard some guys with this swap in full size truck and hot rod cars reporting 25mpg or so. Mpg should be stupid good in something as small and light as a hilux, and performance (even stock LS) should be amazing.
    I know dirty dingo makes mounts for about anything LS, even a "universal" mount set.

    As far as the harness check out "Agearhead4life" on YouTube. He does a lot with LS motors and has a video of how to turn a stock LS harness into a low budget "stand alone harness".

    Might be the same person mentioned above that i saw post a video on youtube, they used the oem LS harness and basically made it a 4-5 wire hook up. Ground, 12v, acc, ign, start

    I've just watched a couple different ones so it looks like the wiring is not going to be to hard to do. I have to swap the rear axle for a 8.8 rear end the stock rear end would probably explode lol so I'ma start with that first then figure a way to mount that thing. I'm thinking universal mounts will almost deffinetly be used

    Or do you think that I could just change to solid upgraded gears and It could handle the power probably 300hp or so ? Need to look into that I like making shit work but if I can avoid the swap I would like to.

    Carb intake is like $600 plus you still have to run the electronics to control spark. Better off using the EFI since the hard work of figuring out the stock wiring has been done by many others

    I never have understood why some people go through the effort of a LS swap only to swap a carb onto it. For me that kind of defeats my purposes in the swap. It does away with the effiecenty and dependability and turns it into an old School setup. Why LS swap, wouldn't a old sbc yield same result for cheaper price if a carb is the route you wanted?

    That and the LS swap completely stock if done right will start and run just as it did in its 2000ish vehicle it came from which is a lot more reliable than any carb setup, especially when it is cold out side.

    Don't get your panties in a bunch, I simply said it as an option.. :waytogo:

    Personally I wouldn't either, but then again I'm not a huge chevy fan as it's the go to for everybody and their brother.. it takes out the originality

    350 SBC with a 100 shot of nitrous would be sweet. 400 is easy to achieve but an extra 100 on tap is even nicer lol

    The SBC is nice but it's so heavy compared tot he 18rc or 20r. I guess the idea behind a carb'd LS is you get the all aluminum engine which only adds like 100lbs over the front axle (a ton that kinda screws up your suspension geometry, but powaaahhhh), and it's as simple as an SBC. That said, a simply wired LS is as simple as an SBC practically, and lighter with more power stock so it's just so much better.

    EFI all the way it has many things I like over the carb. One being the highth I think with a carb and air filter, I would most definitely have to cut into the hood or change it some how.
