I grounded my engine today. I made my own wires and everything with 8 gauge monster cable ground wire and terminal connectors.

I notice a little difference especially in starting it. It literally takes half a second to start.

Anyways i grounded it on the TB, intake mani, and the vtec solenoid. Anywhere else you would suggest grounding it? Maybe the alternator?

 

alternator, and the thermostat housing. also if you already haven't, upgrade your tranny and engine ground wires as well.

 

Ok will do, the ground to my valve cover is not there. Just an empty hole. So i need to get a new bolt to ground it. What is it, 12 or 10 mm?

 

its a 10 like the velve cover bolts
