That's a pretty accurate guesstimate, just working off the figures,
especially having no experience of the engine, but it will definitely cope
with 3.54:1 diffs.

The 4/203 will outlast the Prima IMHO and the 200 Tdi without the turbo
is
lacking in power. Seeing as it's already fitted and working well I would
stay with it but put the high diffs in, the 4/203 doesn't last or like it
if
held at high revs for long periods but will last forever if the speed is
kept down and the torque destroys series gearboxes if abused with the
bigger
Perkins engines. The only problem with the engine is the price of parts,
but
used properly you will never need any.
