This is an endurance engine through and through, so I had to think out extensive planning on cooling methods. Having 1.5 years timeframe, it gave me time to come up with very clean and creative ideas. Here is a pic showing all the coolant feeds, and oil feeds. Once nice tight package considering there is 15 lines there!

CNC oil port plugs. Had "DAR" cut into them. Defined Autoworks Racing of course

Had to go old school on this one, the ITB airhorns were anodized the same green as my very first 20b back in 2004.

Another challenge was the variable intake. Uses metals that cant be welded, so I had some split flanges cnc cut. Notice the counterbore, this gave 1/4" more travel on the intake.
