The pic links are broken in the Pace chargecooler install "how to" so here are some to give you an idea:
The pump is gravity fed so needs to be at the lowest point in the water circuit, so you'll struggle to find a spot if you put the chargecooler itself where the standard intercooler is.
Also, on the coupe the chargecooler is normally run in series with a sidemount intercooler (either the standard one or the uprated Pace side mount or clone) as there isn't space for a big one, so the pump would normally go at front right as shown in the above pics.
"Fastedd" on the old forum was the only one I remember fitting a chargecooler without an intercooler but he went for a custom double width unit and moved the battery to the boot to make space for it. That system worked for him pretty well. I thought I had some pics of that but can't find them now.
I also had a slightly different chargecooler system on my current coupe (Pace chargecooler, bigger Bosch pump + bigger Range Rover oil cooler as chargecooler radiator, mounted where FMIC would normally go), but it was too restrictive at high revs so I replaced it with a FMIC.
Bosch pump was too big for the normal spot so ended up here, at side of uprated side mount intercooler:
And the Range Rover oil cooler as c/c radiator:
There were 2 different Pace chargecoolers, but the first one was slightly too tall and ended up rubbing on the top of thermostat so they changed to a smaller version :
Problem was, the bigger one was more free flowing:
and the smaller one was too restricted with anything other than the standard turbo, even a hybrid is restricted at high revs :
