May I ask why you sold the silver one? If your gunna do boost you should put the 4-cyl back in there. Probably will be around the same weight as a six and youll make more bhp than the S52 n/a. I think its cooler to explore the road less traveled but most would just call that weird.
Turbo M54 will probably be cheaper than a Turbo S54, reliability/maintenance wise. Im not a big fan of superchargers unless its a twinscrew.
What are you after? Interesting/unique. Crazy hp numbers.
By the way your a good friend for giving him your bumpers! I like that.
