Quick question…the S13 battery is grounded to the Battery tray and then contibues to the engine block…where on the block does it connect?? I cant remember!!! 
Thanx
You should be able to ground it anywhere on the block. On my last swap I went to the forward most stud on the intake manifold.
Intake manifold…
Pefect…thats the ticket! There is a standoff on the front portion of the lower manifold.
Thanx!!
