Great article in Excellence about your product. I can't wait to see what the results are from your bench test.

Interested to see dyno and final pricing. Any interest in building 4 valve heads that fit Type 4 motors?

I think this engine is a 911 with two cyls cut off. One of the 356 outlaw guys built it. As I remember it was expensive.

(IMG:style_emoticons/default/biggrin.gif) well its my opinion that ...some enterprising person could just remake ,in mass, the 911-4,(that custom built engine from the 1980,s shown above).all the engineering ,all the parts-custom crank, cams, etc were MADE IN AMERICA.I have seen that engine.(or one just like it.)...Its is really neat!,a real engineering masterpirce....and would fit into many porsche cars with 4 cylinder engines...it,s the cost however that kills the project, unless it could be mass produced to lower the per unit cost. Do not overlook the EXISTING and available custon engines and parts,used primarily for DRAG RACING.(V/Ws).I havent seen or heard about any of the 914 guys using ANY of these available engines and they are half the "PROJECTED" cost of the 4-valve german custom engine.AS a note of intrest it is a fact that the Carrera 4 cam 2.0 L of 1963 -1964-1965 has one of the highest H/P outputs for Normally asperated engines in History..they used 46 IDA carbs. and were a TWO valves per cylinder engine.

Who knows... Martin is slow at his projects, but he always seems to get it done. He's still here and has been selling his 914GT 915 trany conversion kit. Spendy but high quality.

The 911/4 polo engine can be bought now.

Interested to know how Martin is progressing with the project as much as the Apfelbeck team. Though with the Capricorn and the Polopolus motor I wonder where that leaves the bugat engine project? I had heard pricing was to be more than 60k???

Irrespective great stuff
