A P80 rad is same for all P80
You will want heater core and hoses.
Also the 3” long 1/2” hose behind the head in front of driver that’s the turbo line sort of. DO NOT BUY ANYTHING BUT OEM.
CTS as well.
Radiators may be nla too.
GP Racing eboi site have Aussie warehouses and business, buy the aluminium radiator and intercooler too.
They sell boost hose kits if you are good making up to what the Volvo ones are.
My V70T with that intercooler, their hose and aluminium tube , an MBC and T5 auto transmission computer made it an epic town car, it pulled like a train, a 2.3 is a slug by comparison.
