pull the dizzy cap off and all the plugs i.e cas plug, plug going to coil etc and spray wd40 in them, dry em then try As for boost you could go 10-12 psi but the issue is fuel and the n/a ecu/injectors wont be happy with much more then that or even that, the motor however isnt a prblem what so ever

Spray some water dispersant spray on all of your connectors/connections, leads & anything that is electrical in the engine bay. Allow it to dry. Some original photos have not been recovered yet.

Hold a Y shaped stick over the bay. If it wiggles you have water try to avoid holding it over the radiator.
