Yes EJ22 block(na modified to cd)
Dyno was a Dynapac hub dyno, this particular dyno is pretty accurate, about 15hp down on a mainline or dynodynamics roller(cars have run 10.2 @ 139mph with 515hpatw(98 GC8 tuners car)), my car ran 10.6 with a slipping clutch - vid link below, you can see/hear its all slip from 4th gear onwards really stopped pulling when clutch slipped my car is also 200kg heavier than a light GC...but i still think a 9 is possible !

Next mod is a new turbo set-up and CNC ported heads, should bring peak torque down ~1000 rpm even with going to a 1.06 turbine housing.... I don’t expect to make any more power on top, its currently stands at the top of the list for the most powerful subaru in Western Australia, closest rival @ 602hp and 715 or so nm
jc255c - what garret core/equivilant is that turbo your using ? what boost ? good power anyway, nice and flat
