  • LS2 1500hp+ Syclone build

    Iīm reading on this forum for some time now.
    And Iīve leared a lot.

    Finally I decided to radically modify my Syclone 1GDCT14Z4M8801391.

    Plans are to put down as much hp as the front diff and transfer case will
    let me.
    Weīll see how much hp that will be

    As the Syclone was in pretty bad shape (at least for my taste), I decided
    to totally strip it and start from 0.

    I will try to get pictures from everything important.
    I enjoyed reading others threads, so I hope some others now enjoy reading mine.
    Iīll keep theis thread updated as often as I have time to do so.



    Basically this is what I do:


    LS2 engine, special buit to handle 2000hp

    built transfer case (yes, I will try to still run 4WD)

    built 4L80E

    Motec M800 ECU

    2 x Garret GTX 4202 with tial housing

    special built rear axle

    4 link on special built rear frame

        We decided to totally strip it.

        The frame got water blasted to get every dirt off it.

        Then it got sand blasted, all welds were rewelded to strengthen the frame.

        We cut the rear part and built a new rear frame with a 4 link setup.

        At the end we had it galvanized and covered in epoxy.

          Custom built 12 bolt axle (some special parts in it and a detroit locker).

          Some other stuff (RPM coil overs,...).

          Itīs more time and custom work involved than we thought it would.

                Is the rear bumper cladding cut up? Looks like Darth Vaders chest plate....

                  I'm thinking it's a license plate holder since their plates are larger than ours.

                              awesome. Definitely want to see how you're laying out the 4-link. What steering wheel is that by the way?
