thats a good question about 2-3 psi boost. i suspect the lag would kill any benefit at this boost range. and perhaps the efrot would be better used elsewhere in the engine. but then again. what do i know. i am the student here. Does anyone know if the head can be milled at all to boost compression. or would that put similar stress to turboing.

Larrybible, ty for your input. ive seen your name alot around here. you have good advice. I am sure you are correct again this time. I know some engines need to be built stronger to allow a turbo. i wasnt sure if Mercedes also needed to be. they have a reputation as long lasting engines. i was hoping they were already strong enough. oh well.

Its just as well. i really didnt want to butcher this car. its in decent original condition except for a few things. maybe someday ill restore it. Ive always wanted to restore a car. i just thought it would be some chevy.
