You will have to speak with Geoff at Eurospeed re the exhaust manifold.
The radiator is a 2 core 4age off ebay from Just Alloy Raidiators Mascot Sydney, it has cost me 576.00 so far with another mod needed on the bottom outlet point to make it go out at 45 degrees to fit the coolflex hoses I have purchased. Actually a 45 degree bottom outlet towards the inner guard would help with all duratec installs.
A 4age radiator needs the bottom outlet moved from left to right and the mounting brackets flip around so the 40mm flange is on the engine side and the 20mm flange is facing away from teh engine.
Another tip which I learen't this weekend. It will help to modify you heater matrix outlet's. take 10mm off the ends and weld in 45 degree pipes going towards the drivers side inner guard. They are to close too this exhuast as they are.
