Does anyone know the limits of which you can safely adjust the timing of the cams on the B16B/B18C?
I'm thinking in terms of bleeding off excess compression by retarding the intake cam, but have no idea how much it can be safely adjusted by.
By my maths my engine is currently 10.88 static and 9.77 dynamic. If I were to replace the internals with ITR items it would make 11.44S/10.33D. If I used the EK9 pistons with the ITR rods and crank I get 12.89S/11.63D
Using a thicker 1mm head gasket I could drop this to 12.37/11.16, could I then bleed off the rest of the excess compression? I would need to retard the intake by 13° to drop the dynamic compression back to 10.35.
Is 13° possible/safe? Minus 10° would suffice probably.
