The Eaton supercharger or any other Roots type SC that sits on top of the engine is not the way to go for a number of reasons.
1. It is difficult to intercool.
2. It is difficult to keep the engine heat from heating up the blower housing.
3. Fitting a custom water to air intercooler underneath it requires you to cut a hole in the hood otherwise the SC won't fit. Alternately, you could fit a water injection system that will do the same job.
4. The Rimmer/Eaton kit does not allow sufficient air/fuel mixture to the rear cylinders. It needs major enginering changes.
5. The Eaton SC will only deliver 5psi boost max. You can run a smaller pulley and speed it up, but this eventually will burn out the bearings.
I see no reason why the intercooler from a 200tdi would not work. BTW,the stock compression ratio is just about perfect.
