Just wondering here if my MK3 which has a MK4 20vt engine in rolling roaded at 211bhp would benefit from a large alloy rad? Reason I ask is a friend of mine said I could have it for £50, it is only 4 months old.....It is big though and will need a few mods to make it fit. Is it worth it or should I just stick to what I have which is a standard MK3 VR6 rad?
