Waterjetted VNT adapters - aaa - 12-18-2010
So I made a flange for a GT2256v via waterjet. This one was made out of 1/2" stainless. It was $90, I hope to get the cost down to 60 or something. What do you guys think about the material and thickness? I can go alot thinner, which would make it significantly cheaper but eliminate the possibility of "beveling" the hole to transition from the T3 opening to to the GT22 opening. Then again even with 1/2" there's not much beveling you can do.

I use 3/8" with no problems, you could probably go down to 1/4" and still have plenty of meat to thread in the studs.

No threads here, I'm going to use countersunk screws.

What was "$90"? Did you have a shop make this? Materials?
RE: Waterjetted VNT adapters - aaa - 12-20-2010
It was a shop. 90 was for both time and materials.

Damn that's expensive! I though Finland is expensive, but I'd get at least 2½ of those for the price.

Well yes, making them in quantity would be cheaper as well. It looks like no one wants them though.

Thats pretty much it. I can make my own from a $5 weldable steel plate from Ace Hardware and a few hours work.
Drill a pilot hole, cut the rough port shape with a torch, fine shape with a carbide, file it to port match and drill and tap stud holes. Its worked great for 5 years now and I'll eventually make another to have a VNT on both my cars after the compound project.

Any idea on what the lowered cost would be? There are plenty of other cars that can use this application as well.
RE: Waterjetted VNT adapters - aaa - 12-22-2010
I think I can make a couple more thick stainless for 60 right now. A thin mild steel quarter inch I can imagine going below 50. More is always cheaper, not sure how cheap the guy will go but since I don't have quantity I don't have anything to talk about with him.

I would buy one if I was doing a swap

Water jetting should be a nice short cut to cutting an adapter. I think $90 is too high though. I've had larger jobs done for $50 by local water jet cutters so if there are other water jet shops nearby then I suggest you shop around.
The main issue I see is that even after the water jet process, you still need to remove some significant metal manually to make a decent flowing adapter. The hole should have the odd polygon shape at one end and a rectangle at the other.
Having said that, I will probably have one cut locally via water jet to save a few hours of time and get precisely located holes. I would go with iron since it will be sandwiched between two hunks of cast iron.
Cheers. you're still a step ahead of me
