Glad to hear it, thanks! Really appreciate hearing that kind of stuff.

Im max out on 19T and would like to upgrade but Ill have to change the downpipe. Dont think the ex. shop will want to do it. LEt me know if you have any questions.
The studs on the housing where it connects to the downpipe? That's good to know.

It would definitely be easier to make the straight flange work, planning on that as a backup plan.

Cheapie ChiWanNese kits are out there for 1/3 the price, but I always try to buy the best as you won't be disappointed with quality.

Good luck with the angled housing..... I used a flat flange 7cm housing on my 19t, and would not have wanted the trouble to fit that flange to the DP on a 7/9. Seen pics of several, and I don't care for the aesthetics of that swap myself.... (Engineer OCD).
I had originally intended on the straight flange, figuring it would be easier to make a downpipe for it, and I do have a rebuild kit for it but have not rebuilt one of these before. I changed my plan a bit when I saw this: https://martelius.com/en/exhausts/jt...nklad-turbohus as well as being tempted by the enormous outlet on the angled flange, particularly relative to the very high temperature (and low density) of that area. I could be overthinking it though.

I'd love to see some dyno testing of angled vs flat vs conical turbine housings on the same car. Would be curious to know how much of a difference it makes.
