FP makes a 37r? I think you mean AMS, they are the ones who started that name for 67mm turbo. I couldn't find a 37r anything on FP's site.

50 trim, big turbo, hahahha.

I'm just ribbing you so don't cry. Sounds like you have a fun beast planned.
From what you say about the scm61, I think a billet 6262 would fit the bill perfect.
