Honda's S2000 roadster has legions of fans who are very happy with its balanced mix of performance and handling. Then there are those who just can't be satisfied.

One of those power-hungry S2000 owners is known as hboy7777 in both S2000 forums and LS1 forums, and he's combining both those worlds between the frame rails of a Honda.

That's good-old American General Motors LS1 iron hunkering down in that Japanese engine bay, with what hboy estimates could be much as 500 hp before the nitrous is added. In a car that weighs only 2,800 pounds, that's gonna be one handful of a Honda.

The project is still in the works, but hboy plans to start with a Nissan t56 transmission, and if it won't hold, maybe try one donated from a Viper. That should do it. You might think weight balance would be ruined by an engine swap like this, but the owner says the aluminum LS1 doesn't weigh much more than the original powerplant and some firewall mods help keep the roadster's handing neutral.

We look forward to seeing what this Japanese/American hybrid can do, and plan to check in on hboy's adventures often. You can too, either at the LS1 Tech, or at S2K International.

      "American General Motors LS1 iron"
      The LS1 is aluminum isn't it?
        • 8 Years Ago
        I think it is. That threw me off too.

        Doesn't the Z06 only weight 2700 btw? I didn't realize the S2000 was that heavy.
        • 8 Years Ago
        No way any car aside from a micro car weighs in at 2700 lbs these days. The 08 Z06 is ~3150 lbs.

      Nothing new here guys have been doing this for YEARS with RX-7's and Miatas.

      Why hasn't "whynot the ls1/ls2" commented on this post yet?;)

      Looks like a drag strip terror, but I'd like to see how it handles. Cool stuff!
        • 8 Years Ago
        I doubt it would handle any worse than normal, the ls1 is a pushrod engine and isn't much if any heavier than the original high strung DOHC 4 banger. And I bet it will still knock down 30 mpg down the highway, as good or better than the 160 lb-ft of torque engine.

      Too bad such a fine engine has to dropped in a body like this.
      Oh well, in order to add value to the car I`d do the same thing myself.
      On the 8th day God created the big 3!

      It would probably be easier to cover which cars have never had a SBC swapped in.
      • 8 Years Ago
      haha, that's awesome. have any of you guys seen the yaris/echo with a rwd 3SGTE swap? hilarity

      Lots of room in the engine bay for a Lysholm Supercharger and 700HP. :)

      • 8 Years Ago
      This will be a sweet little number. RX-7s with the LS1 make for quite the fun ride and still handle well. I bet this will as well.
      • 8 Years Ago
      but why?
        • 8 Years Ago
        God bless America!
        • 8 Years Ago
        the answer to nearly every mod and engineering feat:

        because you can =P
      • 8 Years Ago
      LS1 should be the base engine in every car.
        • 8 Years Ago
        Lol. Just imagining a Fit, Yaris, or Aveo with an LS1 makes me laugh.
        • 8 Years Ago
        @Jeremy

        Exactly, they'll be funny and, hopefully soon, extinct.
      • 8 Years Ago
      Notice how much room is left in that engine bay--they should throw small-block V8s into everything!

      This is what hybrid really means in the automotive world. It is a shame the hippies had to steal the word for something completely opposite in purpose.
