Ok whats confusing is I see you have a 79 I have an 87 US I guess those dizzys are different. Do you have vacuum advance, or is it just mechanical? Mine is tapped from both sides of the TB. The top port will advance timing on vacuum and retard on boost pressure. Also I thought I was reading that you set your timing further advanced than the factory specs by the number of degrees of retard that you get at full boost. I have always set mine dead nuts on 26 degrees btdc 4000 rpm top hose disconnected and plugged. I personally don't have the guts to advance it more than factory spec especially with the **** gas we get around here. Did you ever get the turbo bracket mounted?
