Sureley the JTD is an 8 valve.. as the JTDM is a 16 valve, the 'M'
stands for 'Multi jet'

The engines are therefore completeley different..

Nope

The M doesn't stand for Multijet, but for Modificata and the changes are emissions related. The bhp output of the Multijet 16v stayed the same when the m was added. The bhp output of the Unijet 8V raised 5 bhp from 115 bhp to 120 bhp when the m was added. The Alfas in NL also got the diesel particle filter when the m was added, but I don't think that is the same in the other countries.

The JTD engine in the GT is always a Multijet with 16v.
