    ... I forget the website, but I know there are folks already doing this sort 
    of conversion ... I say more power to you!  ;-)  I love the off the line 
    jump the PT has over a turbocharged engine.

    Tony's given some good advice, but I do question the statement about the 
    flywheel availability.  I got a  brand new unit not too long ago myself.  If 
    they are unavailable here in the states you should be able to get them in 
    Europe ...
