The TCKWP328 fitted my JDM V8 fine so should fit yours as well.
This is what I ordered.

I had no issues with them. For the money I found them good value especially compared to the AVO/Garret turbos I have used in the past.
On my ADM 07 sti I had the TD06sl2-20g then changed to a TD06H-60-1.
I used the TD05-20g T/S on my V8 sti. If I was to get another one I would probably get one with the billet comp wheel.
There’s a company in the US called Steamspeed that have a few that look ok.
