Yeah I marked around the ports matched up the IM gasket and etched the Gaskets ports and dremeled it out. The head did not needed to be ported seeing that the gaskets were a perfect match to the ports.

Turbo is going to be sent off to an Aussie shop called Hyper Gear.

If you need we can provide the PU service which runs of a customized .82 turbine housing that is good for 20psi and 280rwkws .
The oil feeding line needs to have minimum of 3mm inner diameter including all the fittings on the way. We can supply the oil feeding line for $80AUD additional.
I will not port the Exhaust either seeing that this is just kinda a DD with some spirited Driving. But like said before the Stock ports are already match though. I will port match the turbo flanges though.
