If you start off with a turbo diesel, is it "economical" or worth adding another turbo to it instead of replacing turbo with a larger one?
Is there anyway of working out what is that max. "safe" power an engine size can get after tuning, i.e if your starting point is 100bhp upgrading to 160bhp would that be too much for the engine (60% power increase).
I was basing this on the assumption that if vw can get 180bhp from 1.4 engine surely the equivalent diesel can cope with that kind of power?
