Hello

Until now, I have been a silent admirer of the work you have done on your 300sd, and have gone about tuning my 671 based on much of what I learned from you

I have a 1984 300d. I am planning to remove the turbo and rebuild it myself. I have a machine shop and am handy with port & polish tools. I would like to recreate as much as possible of what you did to your turbo including adapting a larger exhaust turbine and upgrading the compressor wheel.

I have seen a few Buick GN turbos on ebay, but they seem few and far between. Do you know of a source for GN turbines, or something else that will work? How did you go about deciding to use the GN turbine? Did you open up the exhaust housing in the vicinity of the exducer? Was the inducer the same as stock? Did you use the stock bearings and shaft? Where did you acquire the upgraded compressor wheel with the double blades? Were the compressor trim the same as stock?

Would something like this work?

Any help would be much appreciated.

Thank you in advance for considering my questions,
