Thats the thing I am thinking, back pressure with a turbo is the big killer, and I am a bit worried with larger cams, therefore more overlap, things could get worse rather than better.
But if you reckon there is bugger all difference in spoolup time between 0.6 and 0.8, I think I might have to speed up the swap.
Smoother onto boost would be good, cos at the moment its bloody violent. I tried upping the boost to 1.2bar on the previous tune and holey fark, 120kmh - 4th gear and only 1/4 to1/3 throttle and the bloody thing got severly bent out of shape, thank god no cars were beside me.
RS500, if it were a 0.73, or maybe a 0.87 ( but I think I would have to give it a spin first) I would be tempted.
But 1.01, now why would you be trying to off load that??????
EVOIV, as far as I know HKS have proprietry on the housings and the comp wheel, which is why no one can buy them except HKS.
As far as I know, exhaust wheel and cartridge can be purchased direct from garret, or be ordered in by your local turbo shop.
Anybody out there got a 0.73 or 0.87 3037 turbine housing they want to off load:D
