Hello Ron First of all, type2 and type 4 parts are mostly interchangeable. The Vanagon automatic, utilizes a piggy back dual oil pump to provide pressure to the transmission. It is this pump that I am using for the turbo scavenge pump. The suction side of the pump is connected to the turbo oil return, and the pressure side of the pump is connected to the side of the engine case at the oil sump. Please see http://kr-2.aviation-mechanics.com/Turbo%20Oil%20Leak.htm The pump sucks hot frothy turbo return oil and passes it under pressure back into the engine case. The turbo oil supply is taken from the top of the original oil cooler boss and is routed directly to the top of the turbo. The Ford engine that this turbo is applicable for has a requirement for 50 psi. That being said, the turbo is getting what ford required. The pump is two pumps driven by a common shaft that is turned by a slot in the cam gear. Both pumps are completely separate, each with it's own inlet and outlets.
Was it worth it? Even though the dust has not settled yet, I can tell that I have a lotttt more power. The difference is like night and day. My pervious top speed was 129 kts. I have exceeded that in the pattern at PTK, seeing 135 kts. My climb was always around 500 fpm ( my KR was over 615 lbs). On a calm day I can now do over 1000 fpm. Your short answer is YES. It brings back that YeeeeeeeeeHaaaaaaaa feeling. It takes the Hum out of Hum Drum and leaves the Drum with a quickened beat. Orma
