the 1.8 td engines with top mount intercooler had garret t2 turbo's.
Not sure about the later Endura engines.As far as i know the endura engines had different heads,could be wrong tho.
when it comes to the N/a 1.8d engines i always found the NON Endura engines to be strongest and less smokey.
i've had a few 1.8d fords, and Every one of them, has driven different and sounded differnt. Whilst being the same engine's.
i find the ones that sound dog rough are the best, funnily enough
