If you guys have more info or corrections that need made, please let me know. Would like to add year and model for each of them. After searching for 2 days, it became apparent that Holset just likes to make wheels! haha. Depending on year and application (auto/manual/marine) You could get an HX40 with a smaller compressor than what you typically see on an HX35. Also kept seeing refering to a CA Smog HX35 that is 54mm.......  So please add info and I will update or correct as needed.

Main thing, I want to stick to OE replacement wheels and actual dealer data or if you find pics of one measured out. No forum key jamming hearsay.

Compressor
A = inducer
C = exducer

Turbine
C = inducer
A = exducer
