Holset Big H1C, HX35 question

[gte]

I just purchased a Holset H1C (for a non DSM motor), it looks to be 7.5" in diameter (excluding the compressor outlet) and be good for 48 lb/min or about 475whp?

Numbers from my turbo

On the exhaust side looks like a:
Sc1
3538830
14 164
02

Intake is:
02l2n

What size is the vband and where can I purchase a matching flange and clamp?

What a/r ratio turbine options do I have for this turbo? It looks like I can get this (but it costs more than my turbo, is there another alternative?)

Does anyone know if that Bullseye T3 housing is divided?

Do I care about the text I cannot read that are circled in the first picture? Does the 14 indicate it is a 14cm housing?

If I counted 8 blades correctly, then "In 1994, there was the Wh1c which has pretty much the identical compressor as the hx35" and "The compressor flows 52 lb/min according to the compressor map."

T3 bep is not divided:

And a simple search would have given you more info than you asked for:

I've already searched and read that thread, it did not answer my questions at all.

What size is the vband and where can I purchase a matching flange and clamp?

What a/r ratio turbine options do I have for this turbo? It looks like I can get this (but it costs more than my turbo, is there another alternative?)

Viable information from that thread, but it does not tell me what size the vband is, where to purchase a matching flange and clamp (there are different bevel angles and clamp types) and what other turbine housings that I could use other than the DSM BEP housing which I cannot use because I need a t3 flange.

H1C/WH1C:

I have the big h1c. It comes on the INTERCOOLED 1991-1993 cummins pickups. It has the webbing for MWE but no groove cut like the hx35/wh1c has. This turbo I term the big h1c because it has a 54mm compressor inducer and same exducer than the 8blade hx35/Wh1c. Since the big h1c has a 4mm larger inducer and the same turbine wheel as the hx35, it is safe to say that it flows enough for between 411whp and 500whp. The diesel sources state that it flows SLIGHTLY less than the early hx35. So 4lb/min less than the 8blade hx35 puts the flow of the big h1c at 48-49lb/min right where a 50-trim or 20g is. The small bep housing is all that's needed to get the most from the compressor and the spool speed is 20+psi by 3500rpms.

If I counted 8 blades correctly, then "In 1994, there was the Wh1c which has pretty much the identical compressor as the hx35" and "The compressor flows 52 lb/min according to the compressor map."

That's a non-ported H1C, so 54mm/83mm on the compressor. This turbo WILL surge if you change to a smaller a/r turbine housing and run high boost. The WH1C was the model with a 56mm compressor inducer which mimics the 56mm HX35 which followed- the WH1C came with a wastegate and 14cm2 turbine housing, which is the only H1C to have a ported cover with the MWE groove. After the WH1C they redesigned the lineup to the HX series which has a much more-durable thrust system for higher boost levels.

These units typically came with an 18cm2 twin-scroll T3 housing, but depending what it came from or if someone changed housings it can have a different turbine housing for sure.
