    Are the transmissions for M46 turbo different from non turbo? I realize
    that earlier M46 had a cast iron housing which was supposedly stronger but
    I would also like to discern if there any other variants.

    There are lots of minor detail differences, but nothing major. The
    biggest difference occurred in 1990 when the turbos got a transmission
    with a "higher" first gear. Also the overdrive originally had higher
    operating pressure on the turbos, then a new larger type was substituted
    that had a higher torque capacity (also in 1990??).

    Hey Boris, down below is a cut and paste of an email I got from John a while
    back, he made up some adapters for just that project. I was going to do it
    and put my name on the "interested" list but decided to stay with a slushbox
    instead. You might give him a quick email and see what's involved.

    In repsonse to requests made earlier this year we now have adapter plates in
    stock to adapt the ' 93 and earlier Ford V8 version of the Borg Warner T5
    transmission to replace the M40/41 and M45/46. If you are replacing an
    M45/46 we will need to machine your bell housing.

    The adapter plates for the M40/41 bell housing are $160. For the M45/46 the
    price is $250 including the modification of your bell housing. Photos of the
    adapter plates are now on our website in the Products/Conversions section.

    We also offer a complete line of performance clutch covers and discs for
    these applications. Naturally, these will work both with the stock flywheel
    and our aluminum flywheels.

    Please let me know if you have any questions.
