... 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
San Jose, CA (USA)
PTx3 ... 2 in cars, one getting ready to be transplanted into a T44 Avant
