Hi,
Thought it might be useful to put together data to calculate compression ratios.
Bore Diameter: 74/74.5/75mm
Stroke Length: 77.4mm
Cylinders: 4
Chamber Volume: 39cc
Head Gasket Thickness:
Head Gasket Bore:
Piston To Deck Height:
Piston Dome/Dish:
Obviously some answers will vary depending on your spec.
Calculator: http://www.gtsparkplugs.com/CompRatioCalc.html
If people can confirm the data and also confirm any data that is missing, deck height for example.
Also it may be useful to compile what standard dish/headgasket thickness and compression ratio is.
Additionally what aftermarket piston dishes are.
Thanks
