Hey folks I am just looking to get some information about this platform. I have a 2012 ZX-14 R. I am wanting to find the compression ratio for different piston and head gasket combos. Here is what I have:

Number of cylinders: 4
Factory Head gasket thickness: 0.030”
Bore: 84mm
Stroke: 65mm
Gasket Bore: 84mm
Deck Clearance: ????
Piston volume: ????
Combustion Chamber Volume: ???
Factory Compression ratio: 12.3:1
Engine Volume: 1441cc

I am looking at using either the stock pistons or Wossner Mid-compression pistons for my turbo build. Without these other figures I can’t calculate how much compression I would lose by just adding a 0.060” head gasket instead… A ROUGH estimate is that it’ll take it down from stock compression to about 11.0:1… But I don’t like using rough estimates to build an engine

Thanks,
Dan
