Hi, desperately need some advice guys. I own a mk6 which I’m trying to use for track days ( when it’s not braking down) recently put a new engine in with a 2.3 bottom end and standard rs2k head and the performance I feel just isn’t there. Run 165bhp on rolling road. It has a omex 600,standard injection, standard cams, standard manifold. Standard box but with quaife Atb diff and 4.8 final drive. Can’t seem to find much info on performance parts anywhere. Also it’s running way to hot and can’t find a alloy road replacement either. I think it has something to do with pulling the heater matrix out as I’ve changed the water pump and thermostat and rad.
Any suggestions would be great.
