The bed mounted twin turbo system on the Datsun 620 was far enough away from the motor to re-evaluate how to supply oil to the turbos, and the best solution was to run a completely remote oil system that included a reservoir, pump, filter, cooler and thermostat system. Not wanting to loosely mount all these components all over the inside of the chassis with lots of exposed lines, it made sense to design one central station that all the components could live on and be serviced with.

An exercise with good old fashioned calipers, all the components in this design were reverse engineered using simple hand tools and no 3D scanning. Once the library of components were defined in digital space, I arranged all the parts to where line routing made the most sense and developed the mounting platform from those constraints. After the main mounting system was finished, a nice and clean aluminum top cover was developed to safely cover and protect all the interior components while also cleaning up the design visually. Air intake and exhaust vents were specifically placed in the contained system where air flow was needed, including some 3D printed grills.

The oiling system utilizes a billet thermostat to distribute oil to the cooler once temps raise high enough to need it, and both the temperature of the oil and its pressure are monitored from sensor blocks to be controlled by the ECU. Fans are turned on once the temperature threshold is reached, and oil pressure warning and alarms are coded into the digital dash to warn of oil pressure conditions while the engine is running.
