I currently have my EJ20T mounted in the car. I have the radiator mounted in my Ghia, I also have the water lines run front to back.
I have left to run the rubber lines for the radiator, finish running the fuel lines, mount the computer and wire the engine, tidy up the engine, remount the intake(reversed), weld my reversed water manifold... the list goes on. Those are
Just to get the engine running with coolant.
Since I'm doing a complete restoration of this Ghia, I'm far from having everything else lined up but that's another long list.
