Holset Question

I recently bought an HX-35W but it was missing the exhaust part that has the v-band connected to it. It's the part in the attached picture which bolts to the turbo with 5-bolts and has the v-band connection.

My three questions are;
1. What size is the v-band.
2. Where can I get one new or used?
3. Whats the part number.

That doesn’t look like any HX-35 I have ever seen. 35’s don’t have v-bans. Are you sure it is a 35.

It's marked with a holset tag: HX-35W. Either way, I found a way cooler exhaust housing in which I'm going to use from www.htturbo.com . So don't worry about it I guess.

Alright, this new housing (12cm) does NOT fit between my turbo and block so here I am back at square one. Have any of you guys changed your exhaust system before and bought a custom downpipe before? If so, where did you buy it? I'm still looking for this 'holset-only' custom 5-bolt exhaust adapter which come factory on the diesel holsets.

I'm looking for the piece which has 5 bolt holes, to bolt itself to the stock turbo with the v-band on the opposite side. Does anyone know where I can buy one?

Don't you guys do any upgrades here or have one off that you guys can measure. I also need to know the size of the v-band. Thanks in advance.

P/N 3533028 should be around $100 new .. you will also need P/N 3535001 which is the gasket.

Thank you. I'm also looking to upgrade my exhaust and was wondering if anyone knows of a place where I can buy that 5-bolt flange in a stainless material so I can weld on a true 3" v-band and extend that for the rest of my exhaust?

Non-Wastegated sort of kind of.

These must be newer design.

Ok, let's say hypothetically I found this 5 bolt connector piece with the vband connection and got the v-band and I wanted to upgrade my exhaust. Where can I buy an SS v-band end to bolt to the other side of the stock 5-bolt flanges v-band?

Please help. I'm in such a rut right now.

Alright, here is what you do. Find a junk HX-40 or get one from a junkyard (or even try calling HTT, Piers, or the likes, they may have some extra's they can sell you) and pull the exhaust adapter off of it, the same 5 bolt part that you are looking for, but with a 4" V-clamp on the back of it. It will fit your stock HX-35 housing, but being a bit bigger it will flow better. I noticed a lot quicker spool when I put mine on with a 4" exhaust. The only problem is then you need a 4" downpipe, but since your upgrading exhaust anyways I would go turbo back, with a 4" DP.

I actually have the adapter your looking for off of an HX-40. PM me if you want it, I'll sell it to you cheap, its sitting on my old HX-35, you can buy that from me too if you want.

One more thing, you will need the DP ebow to use a stock exhaust housing with a stock exhaust. Buy a 4" DP (HX-40 style) and the HX-40 Exhaust outlet flange and your set.

Alright, I'm going to be completely honest here. I don't drive a Dodge Ram. I drive an Eagle Talon. I put a Holset HX-35 onto my motor and I'm looking for something to work. This is how it sits right now. Pictures are as attached. I'm likely going to get a waterjet place in town to cut me the 316SS flanges for the 5-bolt housing and have a 3" v-band attached to it. It seems to be my only real option.
