EFR6258 and EFR6758 available now in .64 a/r housing only, do not underestimate either of these turbos!!! considering the ultra low inertia lightweight rotating assembly - on a 2.5L - i doubt you will see much improvement vs cost on such a small twinscroll EFR turbo but it will be interesting to find that out once the turbos are available next year. Summer of 2013 (we are told july) is when EFR 2 will debut. EFR 2 will include the 1 new turbo and a bunch of new housings:

mixed flow 7163 turbo (same turbo as initially discussed in this thread, but production versions will have ~12% more performance over the version he tested)

new EFR2 turbine housing options:

-twinscroll 0.80 a/r for 6258/6758/7163

-singlescroll .86 a/r for 6258/6758/7163

-vband inlet/outlet option with IWG for all B1 singlescroll turbos

-vband inlet/outlet option with EWG for all B1 singlescroll turbos

-1.45 a/r for EFR8374 and EFR9180, ideal for larger displacement motors such as 2jz OR anyone looking to make a legitimate 1000whp on a single EFR turbo. testing on this thing shows its a monster

i am attending PRI in orlando, Florida this week and will be sure to snap some photos
