listen lads if you have got a road car ............ then you cant beat the spool up time of an internal wastegate gt30
some of these turbo's can make postive boost from as little 1200rpm not loads but still enough so the engine does not feel low comp
i love my gt 30 i would never ever go back to a T34/ or a T38 too laggy for normal road use
I dont know what spec this turbo is
