We have two coolant Re-route systems available. The Turbo Re-route and the Racer Re-route.
The Turbo Re-Route System
is designed to promote greater coolant flow thru the rear of the cylinder head. The spacer has bungs for the temp. sensor as well as the heater core return. A third bung is included for any other sensor you would like to add. It is a 3/8 NPT. An optional 4th bung can be added if needed.
This spacer runs the coolant from the back of the cylinder head to the upper radiator hose. The front thermostat will be blocked off. It will leave the stock heater core system intact for normal warm procedures.
The Turbo Re-route System includes gaskets, mounting hardware, rubber and aluminum routing lines, hose clamps, rear thermostat housing, front thermostat block off plate, Kia water neck, and thermostat. The final version does not have mounting tabs on the intake manifold.
** NOTE ** This is the revised system that used to be call the racer re-route. As it leaves the heater core intact, it does not need to be called the racer re-route.
The second system is the Racer Re-route
. The Racer Coolant Re-route System is used on any Miata to help reduce operating coolant temps. It runs the coolant from the heather core (at the firewall) to the upper radiator hose. It eliminates the mixing manifold, therefore making engine warm up times increase. The kit includes gaskets, mounting hardware, hose clamps, coolant line plug, and an upper radiator hose splice.
We thank you for all your help in getting the right parts together and called the correct name.
