so i threw a an aaz(1.9td) lump in as it was the best motor i could find at the right price i also intercooled it while i was at it., my question is, do all diesel passats of this era have the same gearbox ratios? cos mine feels a little too rev happy, is it worth me dropping in a 1.9td gearbox, also while im on has any body fitted a bigger intercooler to this chassis of passat?? i cant leave anything alone ive just got to tinker!!
