Hi Diana
When I had my county it had the V8, when I fitted the Isuzu I reused the V8 radiator as it was only about 6 months old and the donor vehicles Isuzu radiator was stuffed.
I took the radiator to a repair place and they swapped the hose fittings over for me.
There shouldn't be any problems having a intercooler out front room wise, unless you are going to run big boost I would leave the intercooler alone, I was running up to 15psi in Nth QLD with no intercooler and it was fine. Most people think running between 10 to 12 psi is fine without a intercooler. If only running these low figures a front mount intercooler will reduce performance as you get more turbo lag.
