Pistons came in and build continues....

CP took forever to make them but now that I have them I can assemble the motor. They have a 2cc dome that puts the static compression ratio at 9.0:1 with the 70.5cc combustion chambers and 0.040" head gaskets.

I have made a few changes to the build plans. I will be fabbing up a new header to improve the efficiency of the exhaust system before the turbo. The primaries will come to a collector right behind the cam position sensor and route straight down to the turbine inlet. It will help to reduce spool time and make lots of room for a larger air intake at the front of the turbo. The new header will be equipped with EGT thermocouples for each head and no O2 sensor port. I will use the EGTs to tune the individual cylinders and a combined wideband O2 reading from after the turbo for the overall A/F ratio. That is the best way to properly tune individual cylinders with a turbo.

Are those ceramic coated base and teflon skirts? I'll be watching this build closely. Nice work!

Looks like nice work Eric!

[EricZ]

Thanks guys! Those are thermal ceramic top coatings and low friction ptfe skirt coatings.
