These header tanks are designed to raise the fill point, making it far higher than the rest of the cooling system to assist with coolant bleeding and reducing the risk of air pockets in the system. These are made with a 3D printed aluminium neck that perfectly matches the coolant port shape on your SR20 head and has the TSF logo incorporated. The neck also has an integrated 1/8"NPT threaded bung in the underside for your turbo water feed plumbing which can also be optioned to a -6an welded on fitting. The top of this tank sits just below the highest point of your cam cover so no need to stress about bonnet clearance. Please use any nissan/toyota radiator cap from any 90's or 00's vehicles. Radiator cap not included.

These are made to order and are not kept in stock. Once your order has been placed please allow for 2-4 week production time.
