thanks for the reply unfortunately both have a 2498 cc engine so size seams irrelevant but i was wondering wether or not the bell housing and engine backplate were the same as i need an engine and a 200 tdi ihalf the price of a300 tdi
the 300dti is an upgrade, its basically the same engine structure, but internal modifications give it more power (altered valve timings, slightly lower mpg) , also the car has a different trim level.
