The 2.8TDI (4M40) is a great torquey motor and will propell a swb Gen 2 along very nicely.
They pump out 92Kw/292Nm which is approaching torque levels of the 3.5 V6.
It is a chain driven SOHC 2 valve/cylinder motor the block itself is virtually bulletproof and tough to almost extreme levels.
Economy figures are around 11-12ltr/100K's on average.
Turbo boost is around 8Psi and they have a fan cooled air/air intercooler. Properly maintained they will achieve 500,000Km's +, turbo life is around 200,000Km's before a rebuild is necesary.
There are a few in my club with 400-500,000Km's and still going strong. A great package in a Gen 2 with super select t/case, factory rear locker and ABS.
