Some of you will know of Corky Bell probably the world's foremost expert on turbos. His book "Maximum Boost" is a best seller and probably the best work on forced induction.
What you may not know is that Corky himself raced Datsuns in the early eighties http://www.datsun.org/fairlady/CorkyBell.htm
He worked for Bell Helicopters before forming his own engineering company specialising in turbos.
He also wrote some aricles on turbos for Nissans and here they are.
