Just bought my first GN. It’s an ‘87. Have no info about car. Trying to learn turbo Buick and identify parts on car so I can get it tuned with TT chip and not hurt anything. Have been researching. Think it may be TE44. No tag or info plate. Has Garrett M 24 L .60 A/R compressor housing. Precision turbine housing. Tried to remove down pipe to see A/R had Allen head bolt strip. Compressor wheel is 12 blade 58mm inducer 75mm exducer. Has 3705-1 engraved in bottom of outlet of compressor housing. Any help would be greatly appreciated!
 
Pictures....
Comp cover, ex housing and pull the inlet pipe and take a pic of the compressor wheel.
There's people in here that know where the nut on the compressor wheel was made. Hahaha

Some version of te44 as you suspect with 58mm inducer.
Pull the turbo or downpipe and study the turbine for the full identity.
