Littco/ beach buggy turbos is based in guilford if you wan tone that will flow 300bhp mine cost me 675 with uprated actuator.
hes the best out there but for the same price he cna build you one that will flow 275bhp
there are few different hybrids out there but
275bhp- K04 internal
300bhp(mine)- i belive contains internals from the focus rs
