I'm currently installing a b18a in a '94 Integra with a LS head. The short block is equipped with p30 pistons. My understanding is I will be running approx. 11:1 compression once assembled. What is the total ignition advance provided by the ecu and will this be a problem running on premium pump gas. Will I need to re-chip the ecu, etc. ? Details: B18a block p30 pistons '96 LS head '94 stock cam profiles aftermarket springs and retainers p75 intake 4 to 1 header This will be a daily driver thus reliability is important. Revs will be kept below 6K. Thanks for the help. PS I can't afford a Hondata unit.
