I'm going to say yes if it's a 4 pot and no if it's the 3 pot, the 3 pot has a fancy flywheel that part of the balance to make up for the 3 cylinders whereas the 4 pot can take the flywheel needed.
You should check out edition 38, they stick the PD150 with 6spd box in the mk2 golfs so it's all possible depending on the lump.
Also you got the PD130 polo, I would've thought it'd have the 6spd as standard. Need to check that out.
