Holset turbo Identifaction

I bought this online thinking it was a 351 since it had the electronic solenoid. Get it and its smaller than a 351 the Comp size is 56mm.

Also it has a port on the compressor housing for something not sure what though. Not sure what it came off of. The guy that had it, had it for a neon. Don't mind the outlet being cut off I didn't do it.

It could be the HE341 from the earlier, '03-'05(?) 3rd gens. The only difference being the smaller compressor wheel. The HE351CW has a compressor inducer diameter of 60mm.

Pull the compressor housing and measure both the inducer and exducer.

I dug it out. Here's a curveball.....My digital calipers were dieing on me and threw me all sorts of numbers new battery in it. and I'm getting a reading of

Inducer: 54.5-55mm
Exducer: 76mm.
BAE Turbos list a 54mm inducer but with a 78mm exducer.....I'm still not sure what I have. because all the "he341s" which in my digging is actually an hy35 type D. has a 58mm wheel.
