I'm doing a full rebuild on my 90 TII and having a PowerFC put in. I'm planning on eventually upgrading a t04r.
I want to know if anyone has had any experience with OBX 40mm gates, and youre opinions. i'm on a budget and cant affort a Tial or anything, but i don't want a universal piece of crap off of ebay.

My other question is, for the time being, will i be okay controlling bost with a 40mm while still running my stock turbo, until i upgrade? Do i need to weld the stock gate closed?

Thanks
