    Hey all, long time lurker, first post. I have been in the design stage of a Hayabusa Manx 4-seat full length build.

    Design Features:

    VW full lenth pan.
    Cut out torsion housing for zero angle swing arms.
    Gen1 Busa engine flip backwards and in the back.
    VW 02M 6 speed transmission for goin fast, crawlin, and reverse. (I live in Colorado, its gotta crawl!)
    Serpentine chain drive to reverse direction.
    15 inches of rear travel.
    Custom water jet plate swing arms using Intrepid Hubs, 930 micro stubs, Maxima rear rotors, and Samurai front calipers.





    Here are some rough drafts.

    Buggy project I bought. Cutting all tube off and starting over, nothing symmetrical which drives my crazy!

    Serpentine Chain drive. Keeping idlers large for long chain length and little bend to keep chain temp low. 160ish links right now. Tranny sees 400ft/lbs of input torque running 1:1 and Busa in 1st gear. I see guys puttin 1000 hp to these 02m trannys. 500 hp seems reliable, 500 hp turbo car probably puts down 400ft/lbs. Another sweet thing about 02m is the cv flanges are 108mm bolt centers, same as Porche 930s.

    The issue is chain driving the trans input shaft. They can not handle side loading the shaft, so you need to use an outter plate and bearing to keep it dead solid. The best setup would be direct drive inline w busa outpu to the input shaft of the trans with a coupler.

    Like this?


    Plan to put a Corvette C6 flex disc to the input on VW trans.

    Welcome Turbo, Forum is a little dead these days but still some faithful followers.

    Looks like a cool project.

    I'm curious about this comment, "Cut out torsion housing for zero angle swing arms.", Why do you not want camber change in the rear suspension?

    Neat!

    I hate to say it but you will probably be better off leaving the Busa in 4th or 5th and shifting the VW trans. That way the torque is multiplied in the VW trans instead of before it. In first gear the Busa is capable of over 500FTLB's at the output shaft.

    Well the 15 degree angle of stock VW is too much camber change (and worse tow change) for 15" of travel. Most badass buggies have zero so I figured it is the way to go. Maybe 7.5 degree is the answer, I have researched the subject but still open on the subject.

    Is there a better forum for this build?
