The Pro runs the SAME diffs as the TQ, UNLESS you use the optional Torsen, the PRO UK runs Spiders for all 3 a standard. The 4 port is the better engine for longevity but the 8 port is a little faster with the same gearing. But it IS a straight swap. The only difference is the liner.
and the piston..
LOL yeah, have you tried to buy a liner on it's own. If it's Brand new though you could just swap the liner as they aren't matched that well, well not as well as Piccos are.
