Mine is a 64 Spitter that s/b back in action 10-13 days from now. I blew #2 piston out, and found out this particular engine was modified for racing, back in the mid 70's. The piston/s were maxed out at a 40/1 vs a standard 8/1.. The pics I have make it look like a bomb went off in the cyl!
I have got a very good hint for you to keeping the nice old Engine in good shape with todays ultra dry eco fuels: Use 1:100 API TC two stroke oil / fuel mix as regular driving fuel, that keeps the old fuel-system gaskets, rubber parts, alloy parts etc... and cast iron metal surfaces of those vintage engines in excellent shape...and it also lubricates the valves and upper piston regions. Most Porsche vintage owners in Germany do so :) Also keeps carbs and tank clean and rustfree
@gordonstanleywood sorry for such a late reply! We got the spit with the servo conversion already done so unfortunately didn't do it ourselves. Very worthwhile doing though as it certainly helps.
@gordonstanleywood Hi I ended up doing the servo unit and it turned out amazingly well on the spitfire. I mounted it on the shock tower, with just enough room to remove the oil filter. We had to put in a single brake cylinder from a GT6 and now I feel comfortable going highway speeds thru' the Rocky Mountains. I had tried everything else to reduce the pedal pressure including bigger brake and clutch pedals. March 24 2011

I notice you have a brake servo! I would like to do the same to help the high brake pedal pressure. Can you comment?
