My Challenge to U /6ers....

I know what archlab is trying to do.

I have a 1994 Camry V6 XLE with the 3L 24valve DOHC 1MZ-FE engine. It gets 30 to 33 mpg on the highway and 20 to 23 mpg around town. It has good power on demand.

3 Liters is equivalent to 183 cubic inches, which is right in the slant six world. I have wondered what I would have to do to get the same efficiency out of a /6.

I figured that I could keep the /6 bottom end but the head would have to be redesigned and fabricated with the following:
1. hemispherical combustion chambers.
2. fuel system on the opposite side of the exhaust system to help isolate the fuel from the exhaust heat.
3. Dual overhead cams to operate the valves. The cams would not be directly over the head but off to one side which would allow the spark plugs to be centered in the chambers.
4. The ports would be of a size and shape to optimize flow efficiencies.
5. The induction would be fuel injection to begin.

To add some classic look to it I would have the exhaust manifold in a tri-y design before it dumps into the collector. Or have dual exhaust with three pipes into one side.

Other induction systems could be fabbed and tried such as special /6 short and long rams with one carb feeding two cylinders. Giving Stromberg carbs an evaluation. Turbocharging, etc.

Of course, the cost to do such a thing would have to be figured out.
