    The Audi 01E is a commonly used transaxle behind V8 motors. I think the 450HP capability noted may be a bit high, but it holding together depends on other factors as well. I believe they are getting harder and harder to find, thus necessitating other options. Even though the 016 will bolt up in the same fashion, it's rating is even lower than the O1E.

    I like the rear sub frame and A-arms, the Audi trans I don't like too much.
    Boxster or 930.

    I saw a Boxster S trans for $1400. tempting ...

    So basically from what I can see when using a trans like the Boxster S if in conjunction with the stock set up I'd just have to fabricate a brace for the lower spindle where the current Corvair trans mounts these. Otherwise it plausible that I could drop in the Boxster S gearbox with new half shafts.

    Sully;

    You will need to fabricate whole new upper & lower a- arm assemblies for your rear suspension if you get rid of the Corvair transaxle. The axle acts as the upper "a-arm" in a Corvair setup.

    Neil I had my 'ah hah' moment and now I get it. The axle is the 'upper' control arm and the lower strut going to the corvair transaxle is the 'lower' control arm and as you pointed out my new S gearbox will need a new rear suspension fabricated.

    I guess I could do David's subframe, a C4 link set up, or something from scratch.

    I'm planning on using my Boxster 987 (2005) six box. Heavier, but able to take ALOT more punishment. Seems to me the way to go is David's C-5 rear subframe with the C-5 rear suspension components.

    That's a sweet c5 rear subframe. Judging by the looks of the lower control arms it looks like the attachment points are stock C5. Who is David? thx
