Hello/greetings etc. I'm building up parts to Turbo my R32 engine, that currently has a slight big end knock. I want to check its 100% before fitting a turbo, but would be wasted time money building it back up, only to then take the head back off to fit a spacer plate. Will there be a problem driving the car round N/A with lowered comp (8:5) on the stock map. Just for a few hundred miles whilst i make sure the bottom end is sound. Many Thanks
