After countless hours of research (and buying but never installing the exhaust slash cut pipe) I decided to go with a vacuum pump for crankcase ventilation. There's many advantages to using a pump over intake/turbo vacuum.
No oil/junk in the turbo/intercooler/manifold and intake ports.
Lower risk of detonation since the motor isn't breathing crankcase fumes.
So after searching high and low and talking with manufacturers I went with the GZ Motorsports Sportsman Pump. https://www.gzmotorsports.com/vacuum-pumps.html
They recommend sending the pump in for inspection every 10-15,000 miles which is a long time for this car. People have reported no wear at 20,000 miles.
Here's my early christmas present...
I started designing the pulley adapter for the crankshaft. I'm using the factory bolt holes in the crank pulley to bolt the adapter.
Here's the system installed on a V8.
I'm going to get all the bits ready so when I get the car back I just have to make the pump mount, measure for belt and hook up the hoses.
Also on the list for the cars return is @DADZSUN new axles and I'm also going to remake my motor mounts to use the stock L series rubber mounts and set the motor at the right height.
