With respect, I thought the title of this post was "Turbo Chargers". I think engine swaps - especially MB engine swaps (for example, AMG engines and V8's) are very cool, but like I said, this post is about turbos.

Regarding cost - I own a small 600 sq. foot shop and the requisite TIG/MIG, Plasma Cutting, Beadblasting, and other necessary equipment. After having built a few turbo setups, I think those numbers are dead on. Also I have to respectfully disagree - it is very easy to turbocharge a car. It is simply a matter of understanding how modern EFI systems work. Fuel, Air and Spark/Timing. That's it. The most complicated part is the Timing and Tuning. As you are very much a car guy I'm sure you know this already.

If you want, I would be happy to talk to you about turbocharging setups and ideas for how to get it done for the M112.
