so do u think that the pajero turbo will be too big for the a14?
no idea I'm afraid. I suspect so since it is off a 2.8l engine, but deisels operate at fairly low engine speeds so maybe not. hey, if it was cheap, try it and see. unless you are making an expensive tubular manifold it shouldn't be too much hassle (or cost too much) to change to a different turbo later if it proves to be unsuitable.

any machine shop should be able to arrange engine balancing for you. they should ask for everything from the front pulley or harmonic balancer to flywheel and pressure plate (won't need the clutch plate), pistons & rods (and the associated bolts for all those bits)
