I looked into this a while back, and the consensus is that 83mm is the max
you can go safely.  If I remember correctly it'll give you something like
2970cc displacement.  I'd ask some one like Jim Chu or Brian Jowett who
they'd recommend.  BTW, Brian did his own 3.0L kit in his Corrado using 83mm
pistons, so ask him for the best advice.

Later,
Greg

82.5mm = 2896cc
83mm = 2931cc
83.5mm = 2967cc

83mm is the most for a normal aspirated motor, 82.5 for forced induction
application.  83 mm = to a fat 2.9L.
