well, owning a 3MPS, im not the best person to answer this, but will answer what i can
firstly, have a look here:
http://www.ozmpsclub.com/forum/tech-...nty-fixes.html
it details a number of issues that people have come up against
the clutch on the 05 6MPS can be a bit tricky, and there is a bit of a discussion about it here:
http://www.ozmpsclub.com/forum/tech-...zda-6-mps.html
but it seems if you find it troublesome, can get it replaced under warrenty
the gearboxes in these cars are pretty solid units, easily capable of handling more power than they have at the moment, and as for rear engine mounts, thats a warranty issue as well, or you can pick up a CPE one for ~$200, and these seem pretty popular with people
am sure there will be 6MPS owners along soon to help you out
