Default Garrett 2860RS w/.86 hotside and a 2.25" inlet $800 shipped

I got a whole kit to put on a build I am working on and then found a wrecked Mazdaspeed to use for parts. It's described in this FS thread:
https://www.miataturbo.net/miata-parts-sale-trade-5/begi-garrett-1-6-turbo-kit-lot-large-pics-61214/

I have decided to part out the kit since it didn't the whole 1.6 kit didn't get a lot of attention. I am including the turbo and the braided lines pictured here. The manifold, DP and assorted bits shown in the other thread will be sold separately. This is Garrett part number 739548-5010.

Since most of you guys don't know who the hell I am, I asked Bob Bundy to take a quick look at the turbo. His comments are here from post #28 on the other thread:

Compressor inlet has been modified to custom diameter. probably so it fits with the other Bell engineering parts.

yea I think that Disco housing originally had an oddball size inlet. I suspect Begi modified it to fit the rest of their kit parts and make it interchangable with the standard 2560.

Yes, it came from BEGI originally. I can post some close up pictures of the inlet when I get home tonight but it is a professional welding job, not a DIY hackfest.

Here are pics of the inlet. It is very well done and the inside is very smooth.

Do most potatos come with a 2.5" or 3" inlet?

I wonder why Garrett have the turbo inlets looking like this with a steepp cone angle:



Does it help the aero? Does air "swirl" in like water draining in a sink, because of the rotation of the compressor blades?

Why not make the transition angle shallow like this?:

Someone did some fluid dynamics testing on these. I can't imagine something as fundamental as the shape of the inlet is by chance.

Any chance you'd sell me just the feed/drain lines and fittings?
