    Not sure it's going to happen but I've been emailing back and forth with Swindon about their 4 valve conversion for 964 and 993 engines. Most POLO's are based on those parts. The cam towers (they refer to them as cam boxes) would need to be developed. Cams would also need to be developed since the engine would go from 2 to 4 cams. So it would be a 4CAM4. A present day air cooled Carrera 4 cam. Spinning a 66 mm short stroke POLO to 9 or 10K would be like a 4 cylinder GT3. Or 8 to 8500 in my current 993 based 76.4 mm long stroke. I find it interesting the continued development of the air cooled engine. What's next?

    On another note the frog will soon be road worthy. Wheels are going from 16 to 15 with CN36's.

    Whoa! Crazy! Are those used on the Tuthill 911K or are those even more exotic (oil cooled?)

    Same as 911K. I just white outed the 3rd head. They are totally feasible. It’s down to time and costs.

    While the axles are off and the car is up on the lift I'll do an oil change today. 13 quarts of Champion 10-40. $186.00 for the oil. I use a reusable filter from K and P Engineering. It flows more yet filters even smaller particles. It also makes it a snap to inspect the filter as it comes out of the housing.
    I ordered a pair of Sebro 20 mm wide vented rear rotors and brake pads from PMB. I'll get the rotors cryoed. Somehow I managed to slightly warp my rear passenger side rotor. Who knows, maybe it came that way? It still measures out to be 19.85 mm. The drivers side is perfect and measures 19.90. Just one of those mysteries. Oh, and I drained the transmission yesterday so I could replace a seeping drivers side rear axle seal. It's amazing how fast I can spend $1000+ on a few small projects.
    Rebuild axles-$275 each
    New rotors, pads, and shipping-$325.
    75-90 dinosaur transmission fluid-$75
    10-40 oil-$186
    axle seal -$8
    cryo of rotors-$120
