yeah i think he has 6 boost manifold, greddy plenum, forged pistons, metal head gasket, rb25 intake cam replaced for rb20 intake cam, running a rb20 ecu remapped. (nistune remap i think - tuned by simon at morpowa) - on pump fuel. 550 inj, 044 pump...
i may be able to get a little more i think - i'm going to change my injectors, because the gtr ones are maxed atm, so had to raise the fuel pressure.
