i have been informed it could be an ht3b which i think is like a hx40 or something i could be wrong and probably am i just had a buddy tell me once it looked like an hx40
Negative chief
Your buddy does not know turbos
A HT3B and a HX40 are nothing a like other than they are both turbos
Take off the compressor cover and measure the inducer should be 74mm if its a BHT3B and 76mm if its a HT3B.
The turbine inducer 111mm, I think, its been awhile.
Is the housing divided or undivided? Undivided is best much lighter weight. Housing is probably a 28cm. It should say on the exhaust housing.
Also make sure its not a ST50 which is worthless. A ST50 has a band going around the center section and a million blades on the compressor.
