i have a sidekick 2dr 97...
*i am planning on installing a second battery, is there a way to fit it under the hood ?

*and am going to engine swap with v6 145hp ... will the ring and pinion take the load or not ? if not whats the best replacement for them ?

*if i wanted to do a  SAS... do i need to replace the rear diff too ?


thanks

Not much room for another battery under there, but you might try
a bigger Amp Hour one instead and an upgraded alternator if you
are thinking about a winch or lights.

As far as the gears, yes they will take the power fine, but you will
probably need to change the rear axle to match the ratios, but that
really depends on what axle you swap into the Kick

Wild

if you want two batteries (maybe to isolate accessories) think modern hi-tech. like Odyssey or other high zoot brands that are half the size of old acid filled batt's and are supposed to to a better job.

If you are planning on installing a V6, don't buy that extra battery yet.  There is not much room left after a V6.

any necessary mods to keep in mind after v6 swap ?

and whats the max battery amp`s without replacing any other parts...i have 45A i think atm

You might have a 45 Amp alternator, but the battery should be in the
600 Amp range, and the tray could hold a big battery, as long as it's
not too tall and contacts the hood, a 950 + Amp battery will drop in

The Odyssey batteries are considerably smaller than a conventional battery of the same output and are 100% sealed and will not leak. They are also available with a tough metal casing.

Here is a PC925 that I put into my Honda Civic, alot more amperage available for it's size, far more vibration resistant and are deep cycle capable. I will be going with the PC1200 for my SideKick.
