i have a z20leh engine to go into my astra 888. but before i think about putting it in i would like to know what the weakness are. i have already sent the turbo off to TD for there stage 2 hybrid
my target will be over 320bhp.
also what gearbox would be best F23 with diff or M32 with diff, cost not relevent as i can get the m32 for cheap.
any help will be great and also some prices would be great thanks
