Got a turbo from a Noble M400/M12.

Was told it is a T25. But internet says it could/should be a GT25R/GT2554R. Pic on ATPturbo looks identical to what I have.

Round compressor intake, 3bolt outlet. normal gt25 turbine housing. FM downpipe bolted right up with no grinding/ovaling the holes like I read that needs to be done with non BB.
M24 .86 a/r on compressor, .64 a/r on turbine housing
chra tag is gone. no built in oil restricter and the oil inlet is the normal reverse flare.

what can I look at to determine if this is BB or journal?

2nd, where is a good resource to find out what parts I can swap/upgrade? IE turbine housing to V-band or use the FM ewg housing, but swap it in the future to a gt28r ect... (what is compatable)

Look at the number of bolts holding the CHRA to the turbine housing if there are 6 around its a BB, and if there are 4 it is a Journal Bearing.
