I wanted to repost this hopefully this is a good spot.

Phase 1

Drive while starting "Phase 2"

Phase 2
Rebuild my currently forged 7a block to use with BT 20v head.
Raise compression

Phase 3
Rebuild head with performance valves and springs, port and polish. Install bigger cams.
Put new 7age 20v motor in car and install megasquirt.

Phase 4
Install direct port nitrous.
