I am starting my 20B build. I already have a large street ported C series 20B with RA super seals. I am looking to make 650 to the wheels. and considering going with a BW EFR 9280 with a 1.05 hotside with a Tirbosmart 50mm wastegate. Does anyone have any experience or thoughts on how this setup would work on a street ported 20B?
