Just wondering what the consensus is with building a turbo EJ engine. Normally I aim for a squish clearance of .035"-.040" (.9-1mm) is this rule still true for the big bore short stroke EJ?
Also there doesn't seem much actual flat face on the head for a squish band, just one at either side of the valves really.
Andy F recently mapped my car and was very interested in the squish hieght. With all the excitement at the time I forgot to ask more about it.
