Question.

What should the ideal gap between the diffuser wedges and the compressor wheel be?

This is my first attempt at building a diffuser. I did it completely by hand. It has some mistakes since I don't have the necessary tools and cast the aluminum at my backyard and it also got some bubbles of air in. I based it around the UT 160 but the wedges are shorter unfortunately.

If you are basing yourself on the UT160, follow the project instructions.

I will it is just the first attempt at making the diffuser.

Yours looks good! Ideally around 1-1,5mm. Some manufacturers have it zero and some even 4mm, depends on compressor, diffuser match.

Can anyone tell me if this compressor wheel is the same used in the UT 160?

This is the comp wheel what will work in the UT 160, see picture.
The wheel you showed above is not correct, inducer is much to narrow.

Succes.
