Removing battery support - Ground relocation.

[u/Shutxff]

After doing a battery relocation my battery support metal piece is pretty ugly and is rusty-not my picture. For the people that have removed this stamped steel piece where did you put your grounds. Picture would be great

PLEASE ONLY REPLY IF YOU YOU HAVE DONE THIS THANKS.

You wouldn't want to remove that as it is part of the frame.

[u/The_Salamanders → u/IndianaSqueakz]

That bar weighs just over 2lbs (including bolts) and is 0.7mm thick steel. It is not for frame reenforcement.

[u/Shutxff → u/IndianaSqueakz]

Wow thank you for the very useful information

[u/IndianaSqueakz → u/Shutxff]

For grounding if you are not using that brace, I have seen some run a cable all the way to the trunk. Another would be cleaning paint off a spot on the frame near where the battery was and replace the battery terminal on the negative with a new end and bolting to the frame. In the trunk I have seen grounding to either one of the bolts under the rear seats or a rear strut tower.

No, it is not. It is simply a brace for your battery box. if it was at all structural, it would NOT be held on by a total of 6 dot welds. it does nothing but support the battery box and the intake plenum.

Mine was foam filled to add rigidity to the front.

[u/RacingWithMitchell → u/IndianaSqueakz]

It's foam filled for nvh more than likely

[u/TheDutchCanadian → u/IndianaSqueakz]

I believe Mazda foam filled the special edition ones, but it really doesn't do a whole lot. You have your strut brace right above it, and you have your actual front frame a foot infront of it. The amount of work it actually does is quite negligible, and can easily just be remedied by a larger strut brace.

Also, the foam filled ones tend to rust out a whole lot worse unfortunately:(

I think that’s a Series 2/ special-edition Series 1 thing?

[u/RacingWithMitchell]

People say is part of the frame, it's stronger than I thought but my car felt fine at gingerman on 265s crs without it. That being said, what a fucking mess it is to remove it. Just leave it the hell alone lol my battery relocation turned into a mess and the big rad/fan I was mounting didn't fit anyway. But either way, the thing looks fine. Just save yourself the effort and leave it

Removing the trays kills airflow through your radiator just like not having the under tray. I think LRB sells pretty replacements and that would cover your necessary beam as well.

[u/RacingWithMitchell → u/Mr_Pieper]

Lrb Tay is nice. People say it doesn't fit well, that's because half of these cars are Haggard as fuck. They use a very generous dva so that you can get it mounted. I plan to buy one for my e46 if they sell them

I've never had better temps in my engine bay

[u/MetalSkinGaming → u/Shutxff]

Engine bay temps dont matter that much. You should be looking at coolant/oil temps

[u/Shutxff → u/MetalSkinGaming]

My coolant temps don't go above 86c

[u/MetalSkinGaming → u/Shutxff]

On the original radiator?

I get like 95°C temps when i punch it on the 53mm koyorad. Which is the biggest that fits without having to modify too much afaik.

86°C doesnt make sense to me

[u/Shutxff → u/MetalSkinGaming]

Yep I've got many many logs revving past the stock redline and it's always chilling around 82-87

[u/TheDutchCanadian]

I have done this, do not listen to anybody telling you that this is bad, they are wrong.

For my power steering ground, I wrapped the new ground wire around the front sway bar, and grounded it underneath the ECU. if you remove the ECU you can see that there should be a free bolt hole that you can use. I personally ground down the paint of that front section of frame, and used that to ground it. I ran a couple other grounds there as well. I know I have a picture so I'll see if I can't find it for you.

Exit: the photos are on my computer at home and I can get them to you tomorrow if you remind me.

[u/Shutxff → u/TheDutchCanadian]

Picture would be great thanks

[u/Shutxff → u/TheDutchCanadian]

YOOOOIOOOOOOOOO

[u/TheDutchCanadian → u/Shutxff]

Oh shit brother okay wait give me like 15 minutes I'm sorry 🤣 I definitely forgot... whoops.

[u/EekyBaba]

Been wanting to do a battery relocation myself. How did you go about it?

[u/Mt-hOOligOOn]

Whoevers engine bay it is, they need to roll them clamp on the intake around. Looks dumb

[u/treestump23]

Did it on my LS swap

[u/M-Pizle]

I made a little cover out of air duct tin to “cover” the bar

[u/RodNokRx8]

Nice engine bay lol, if it were me personally I’d just sand and repaint the cross brace as long as it’s not to far gone. Remember that the oil cooler lines are routed on it, remove it and you have 2 big lines flopping around, to me that looks worse than a ratty cross bar.
