Next i need to replace the throttle body, the TB on the Z20LET is fly-by-wire and i cant run that on MS2 (or cant be bothered to work out how)
I've bought a throttle body of a X20XEV which is effectively a NA version of my engine (2.0L 16v from a vectra/astra etc)
Its fits straight on and converts to cable throttle, its slightly larger which cant be a bad thing.
I actually ended up turning this round 180 degrees so it fits better.
