Passion, not Practicality.
Good day, All. I'm in the process of building an offset bored 903 turbo motor using a bare block I procured (I don't have the factory pistons, and I'll be using custom pistons). I can't find the factory piston-crown-to-block-deck clearance spec...which is critical to properly specifying compression height on my custom pistons, in order to achieve desired static compression when the motor is all buttoned up.
Here's what I understand thus far about stock 903cc engine specs:
Anybody know where I can find the stock 903cc spec for deck clearance? I'd rather not rely entirely on my assumptions and math.
Here's what I understand thus far about stock 903cc engine specs:
- 65mm O.D. piston
- 68mm stroke
- 110mm rod length
- 24.3cc chamber volume
- 30.75mm piston compression height
- 1.14mm assumed head gasket compressed thickness
