Here is how the setup was when my 914 had the 2.8L type 4 engine and I'll start with the engine sump.

- Used an Auto-Craft sump plate with studs to the case to hold it on, suction fitting was a 90 degree -16 welded to the plate.

- Auto-Craft 3 stage pump, one suction was on the sump, one was with a connection at the tank, both were -16 size, outlet went into engine oil passages.

- Outlet from engine went to a front mounted cooler, no thermostat, -12 size Earls hoses.

- Front cooler was an Earls that was as big as we could cram in the front trunk area with aluminum ducting out the bottom.

- Return line was Earls, -12 size to a dual filter unit we bought from Summit Racing.

- Outlet from filter went to the oil tank, was -12 size.

- Oil tank held 12 qts of oil but had to keep lever below top baffle so it probably around 8 or 9 qts actually.

- Puke tank was aluminum that vented the engine case and also the oil tank. Note that at high RPM the crankcase is actually under a vacuum which helps HP and offsets the power required to run the oil pump.

- Cooling was converted to a 911 alternator and fan with a fiberglass cover and duct work, used stock engine baffles and such. This was required because of the large size of the oil pump.

It worked great, was expensive but never let an engine fail!
