First i wanted WBX case, but you can put longer stroke to TF-1 case, due to 0.100" dropped cam line. It has also trough bolts like T4
But wbx case is very good.
G50 is definetly great, but i dont like long ratios, like 3.33 R&P and 3.5 or 3.15 first gear or similar. Too bad that lower R&P ratios cost so much for these transaxles, otherwise best porsche trans. But for turbo motor good choice

EDIT: I think i'll need to rethink these ratios, G50/00 , G50/01 and G50/03 sounds better than rest, these have 3.44 R&P and 3.5 first gear.
I found this new type of head from cal-look.no, i may have confused, these heads are only offered by T. Pieper
