So I've heard of the 528e block with the 525i pistons and head on it, and I've located the 2.7l block and crank. What about what about putting a small, low pressure turbo setup on it, like 6psi or so. I also happened across a good turbo off of a volvo 240/740 non-intercooled motor, should be a Garrett TB03 AR .60. Is this comparable to a T3? I know very little about turbos (just that the one on my Duramax makes things FUN). I would like to run a lower mounted turbo with a small front mount intercooler.

I'm not looking for insane horsepower, but I would like for the car to "get out of it's own way".

The car is an auto right now, but I'm slowly sourcing the parts to do a 5-speed conversion.
