Grounding isn't too complicated....its just a buncha wires and terminals really. A better question is "WHAT do i ground???" And that is answered in the archive i believe.

In fact..heres a link: https://www.rx7club.com/2nd-gen-archive-72/grounding-how-thorough-discriptive-199558/

 

Aaron Cake is comming out with an end all grounding questions thread in less then a month. id wait until then before i spend all that money.

 

Grounding doesn't really make anything better, it just helps to fix old grounds that aren't as good as they once were. The added horsepower, lowered stereo noize and so on really happen because it fixes an underlying problem, if there's no problem, then it's pretty useless. That said, most older cars can benefit a bit from this.

Why are you wanting to do this? Is it to fix a problem, or because you want to add another mod to the list, or because you think it'll make the car faster?

I've looked at the reccomended grounding points and they make a lot of sense to me. You may as well follow the procedures outlined in the archives or on the Rotary Ressurrection site. If you're looking to solve a problem, then doing the ECU and sensor grounds would probably be a better bet, and I would question the need to ground the shock tower, a better thing to do would be to re-do the stock engine and chassis grounds.
