Could also try using middle red button at bottom of post ( upload a file) , although the file needs to be smaller .
Don't know about the charge air intercooler but the optimal front mount intercooler radiator judging by mine on the v2 goes in front of all the other radiators.
Not sure about pump.
My immediate thoughts are the harrop would end up costing more but you'd think would be a little better, ( newer and more direct air intake), and neater looking.
I would suggest ringing and talking to both harrop and yellow terra.
Back in 2014 when I was trying to decide what way to go ,( it went from supercharge the V2 monaro to do the VS Maloo and ended up doing the monaro , but I rang the guys at yellow terra and talkedto them about doing the maloo and they were very helpful and informative .
As long as done right I don't think you'd be disappointed with either.
In a vn you won't be putting your foot flat down in 1st or 2nd without breaking/ fighting for traction.
And in the wet you'll have no hope.
Even in my V2 monaro, which I haven't even modded to it's potential, in damp / wet conditions I've got no hope low down in 1st and 2nd .
Even one night, way home from work, damp, straight line ,right conditions , 3rd gear , 70 , 80 klms , probably only about 1/2 throttle , hadn't disengaged traction control and it kicked in .
