So much to do, so little time & even less $$$$. The car came with cone filters and huge catless downpipes and a stage 1 something or other. Looking to do the crank hub fix/swap from Vargas.Also the bigger inner cooler and larger intake pipes, swapping the turbos chra to the TD04.and go to the next stage of tune.Needs to be dependable and be able to stop Which is how I came across the article on this website doing the F-30 brake conversion.outstanding work by the author. I won't be posting much if anything But I'll probably ask questions as BMWs like this are new to me. Good to be here, so far.
