I have the 2.0 SC TB - 68mm with flange.
The car at the moment looks like this

I have to install the 2.4 Manifold PCV seal gasket, still waiting to get it from the States. To install the Intake pipes from Vectra C to the airbox and then the dyno run is waiting for me.
Still my car is not mapped, running on the stock maps, probably the AFR is 14 or more, i want to be 12.8-13.0 tops, still working on it who can do it for me here in BG.
