Your comment on the compression ratio is old school. There is no need to run such low compression on a turbocharged motor. Unless you are running crazy boost. Low compression ratio's result in greater turbo lag.
$4,200 for labor??
$1,200 for fuel lines and fittings??
Some of the prices are right in line (depending on specific part numbers). Some of the prices are very high.
My comment on the turbo needs to be clarified. Yes there is lag, but once the turbo spools, there is a lot of power at once (typically all the way to red line). Superchargers are linear and provide boost all the way through the RPM range; no lag.
Old school? Not unless we are running forged pistons, heavy rods, and main bearings...but what do I know? I would be very surprised if Mercedes uses a Pauter comparable piston and rod in the 3.2 Liter. I did not comment on labor because his list was incomplete. I stated no need for fuel line and fittings because they were not needed (but larger injectors were)...ties back into the one fuel pump fits all (from 4 cyl to 8 cyl) regulated by the FPR.

A turbo doesn't necessarily void the entire warranty. Obviously it effects the engine. At some point most of us are going to become tired with the HP numbers that we have regardless of the model. Superchargers are difficult to upgrade and are mechanically limited to the amount of boost they can provide (governed by the size of the pulley on the front). In comparison, turbos can be easily swapped for more boost.
Personally I LOVE THIS CAR!! But I know that I am a car wh*re and will become eventually bored with it. I may twin turbo it out of spite. Why? Because the thought of a supra similar 1,000 horse power street legal X-fire would be ridiculous. :-) I guess I would not be able to Auto-X anymore though. LOL Maybe drifting??
Cheers and thanks for the comments/observations.
