Montego T2 must be the Perkins Prima unit - which I recall is a 0.35 AR turbine and a 50 or 55 trim compressor...

The Montego Turbo diesel is a 4 bolt flange, .35 exhaust .55 compressor iirc.

If it has the 0.46 turbine, that is actually pretty good for a 1293. I must be having brain fart however as i was sure the Prima was a 0.35 A/R.

Might be worth measuring the compressor to be sure, but if it has a 0.46 turbine, I can't imagine it would be less than a 55 trim however.
