r34 relocate battery

[drifter17a]

all, 

 

I know this may have been asked before but couldn't get a direct response to what i needed

 

I have ran the cable to boot and ready to relocate. i want to mount the battery on the top shelf by removing the hicas ecu.

unfortunately there is no bolt or whatso ever to hold the batter in place. I am thinking of drilling a whole on the top shelf but my question is, is the top shelf very close to fuel pump / plastic pump and I could put a whole in the tank?

Yes it's very close to the fuel tank, getting a bolt or 4 in there (properly) will be a bit of a headache too. Pull off the fuel pump lid and have a look under there to get an idea of what you're working with - I'll give you a hint, it's not very much at all.

In terms of drilling into the tank, yes it's a pretty real risk so be careful, or re-consider your need to mount it in that exact location.

Also, after you remove the HICAS CU, don't be surprised when a whole bunch of stuff goes wrong.

yeah very small much tiny space, did place it on right hand side

 

i am running positive through a kill switch which is the one below

how would you cover the bottom when wires are in to ensure it won't touch body etc?

i am thinking a battery box but rather not buy one as have a battery bracket but this needs to be inside something

I mounted mine up there using a boat battery dry box and fastening it to the plate behind the rear seat back rest.  I wanted to avoid drilling anywhere near the fuel tank.

R33's had the battery in the boot and the battery holder bolts straight into the r34 the holes are already there. I had to modify the bracket for the ecu behind the battery though to make it fit. Here is a pic but it is not finished.

Yeah but i don’t have that bracket

That's understood. The suggestion is if you buy one it will fit nicely .

[drifter17a]

Just got a bracket and box so will fit it on sidr

[GTSBoy]

Sheetmetal + saw + folder + welder + spray paint = any bracket you need to mount that battery anywhere.

Go to it.

[drifter17a]

No welding now but all sorted ....

 

so here is my question, I can just cut the negative cable at front of the car right?

i connected a negative to body and checked it is grounded

[drifter17a]

Bump:)

I cut the piece from the battery to the chassis leg and left the remainder which connects the engine block to the chassis leg and everything works fine.
