turbotechnics are THE turbo people end of story, like anything you get what you pay for and with tt you get quality!!

mines a grp a t34 ar .60 comp housing, .55 e/h, rs500 80mm intake nose, anti lag compatible marham 247 shaft, ...... i was adamant with a "low lag" conversion hence smaller e/h

the back pressure on a .48 e/h is immense at 2 bar and will crack the ex manifold

my breather system/catch tank is a turbosystems unit
