To handle the increased load on the cooling system from the engine build, as well as getting it for an excellent price, I purchased a custom alloy radiator from Just Alloy Radiators. I had it made to the same dimensions as the original radiator, but with a 52mm thick core.
Some small modifications are nessecary to ensure perfect fitment. I have to install brackets to mount the thermofan and modify the top hose connection to exit the radiator at 45 degrees.
Updates to come...
