Steve does very limited engine work anymore. He has moved several times, his dad, Art Miller still does a bit but I do not have his #, still the same address you posted. Although Art does not do the turboing, I have had it done by Steve and am a believer, fuel/air is way different with it, some sleds it works others it doesnt! His new shop is on Michigan rd in Saginaw/Zilwaukee Michigan, same name, you might give that address a try.
