upgrading "big 3"

I have a fear of having too big terminal holes..

Also fear of alternator failure(them thing na cheap).

SSC i was just asking if you ever did any cars big 3 with 0awg..

alt won't fail because the 'current pipe' from it is larger.... it will if you demand too much of it. With even 4AWG you can demand too much from a stock alt.

Anyway, I gonna do over mine with 0 or 2 b4 month's end since the 4AWG that's there came with the car and is old looking and getting stiff. Bigger alt too is the main reason.

in the design of the alternators is it even possible that the studs are of adequate conductivity for its size and not be a restriction causing melt down?

And more over... for a stock alt he eh hadda worry bout nutting Confused

I'm about to do this myself next weekend. I just have one question for those who've already done so:

Where exactly is the Engine block ground located on the QG15DE. I've looked at a few instructional videos and in some cases the connection was run to location that already had a stock ground connection.

If there isn't one on the QG, where would you guys recommend as a safe place to secure it.

In those engines, the grounding spot is on the transmission casing, just under the battery tray.

Thanks 3stagevtec and silent_riot . I'll look for the connection later and do the upgrade over the weekend.

After that i'll look at changing my alternator. I hear the Tiida has 140A ? That should be enough for my system cause I don't think my current 80A Alt can keep up.

^^^ i saw a difference when i did the big 3, the stock wires in the honda accord were 8 gauge and i upgraded them 2 4 gauge, except the battery to chassis which i did in zero gauge.

i noticed a difference with dimming lights when playing music. also i not sure if this is to attribute to the big 3 but bass is also slightly deeper, and amps run a little less hot, in terms of voltage i really cannot say as yet, but will check later.

also what i wanna do next is change the battery to chassis ground to the shock tower apparently this is a better place than stock.

^ either will do.. actually, any free bolt on your engine block will work..

but pick the safest of the two locations! connect your engine to a cleaned point on your chassis, and connect that same point to the negative terminal on your battery.. that is the best possible connection setup for grounding.. Wink

another thing, don't remove your factory wires.. if in case the new wires you run have a fault, you can fall back on the factory wiring..
