I am currently making a mk2 vr6 with a smoothed and shaved bay. I have the coolant bottle in the boot along with battery and washer bottle. I have run pipes from the front to the boot but I am needing extra water pumps to help get the coolant to the front. My choices are: Fit electric water pumps and keep hoses to front. Buy a radiator from a fiat or Nissan with a fill up section on it and custom top rad hose. Keep mk3 Vr radiator and buy a filler neck and make custom top hose and fill up that way?
