Trevor, Thanks for the feedback.
I need to decide in the months to come, wether to run in the under 2 litre class or over 2 litre class (club cars). I am looking at either 250hp from NA or 300-320hp from the turbo. The under 2 litre class here in NSW is extremely competitive. to give you an idea, the top 5 cars in the under 2lt would run easily in the top ten over 2lt, in fact, at the last round this year at Eastern creek The guy who won the under 2lt championship would have finished third in the over 2lt final. That's in a 1300cc suzuki swift (old model). I will be building a monmster FJ this coming year, wether or not I go turbo is yet to be decided, but I really don't want to change my current gearbox, as it has the hollinger gear set in it - awsome box. Again thanks for the info on the gear box's and restrictor.
