Replaced 12v battery with a bank of 3000F supercapacitors. Should be good for a ~25lb weight reduction. Starts the car far better in subzero weather than the battery did.
Engine and transmission are fully assembled and just waiting for a home. Got 50 degree VTC actuator installed, new alternator, new thermostat + housing, new A/C compressor. Turns out the JDM K24A has a different water pump housing which doesn't line up with USDM accessories so I replaced that too. All I need now is for Hasport to release their mounts and axles.
