thanks for the feedback on the EFR turbos - the billet compressor wheel, integrated BOV, and investment cast stainless steel housings are definitely exciting. once you see the inside of these stainless housings, and how smooth they are its really impressive - porting these would serve no purpose.
I got a just got a shipment of pre-production EFR's in, my office feels like its christmas:

I want to see the presents!!!
I may have missed this somewhere earlier... but what sort of price point would most of these run at? Hypothetically, my buddy is running an S362 on his evo 9 and I'd maybe try to talk him into one of these guys... what sort of cost would he be looking into for a mid 70 lb/min one? As to be an upgrade over his S362. Feel free to PM me if you'd rather.

yes all of the EFR turbos will come with a SS turbine housing in twinscroll T4 (divided) or singescroll T3 (undivided). The integrated BOV/DV comes standard, at no charge. If you wish to run without it, its very simple to remove.

sorry, the vband clamp did not pass borgwarner's durability testing so this design was not released. EFR turbine housings are stainless steel so if you wanted to do it badly enough, you can weld a vband flange on, but i dont think that is worth the effort when you could just go twinscroll from the onset.
