First I would like to apologize for my bad English. I come from Denmark.
And i really need some help.
I am having big problems finding out what my compression is going to be on my Engien.. :/ I have tryed most of the Honda B-sereis Calulators on the internet. And they can not help me.
It is because i think i have gotten the wrong pistons from "cp"
My enginen is a b20b3 whit b16a Cyllinder head whit Oem head gasket.
And i have baught an Brian Crower 92mm Lw stroker kit
And i have ordered the Cp pistons so the compression should be 12.5,
if my head og blok is like stock and not milled
But there is certainly something wrong whit the pistons.
Because i had 12.5 i compreesion when it was 87mm stock stroke and running whit the old Cp pistons in my old setup. And over the deck the old pistons is 3-4mm taller then the new pistons.
So now i have to calulate how much compression the new pistons will give me so i can be 100% sure that the dealer i baugt the Pistons from can change them to the right pistons.
The Data sheet is:
Crank 92mm
Bore Diameter: 3.347
Clearance 0.0040
Piston gauge point 3.343
Compreesion height: 1.024
Intake valve Relief: -0.21
Exhaust valve Relief: -.150
Dome Height 0.063
And the rod size is 1.7710
and Main size: 2.1646
Ans Something called Rod C-to-c: 5.512
And Oem Head gasket.
And that is all the data i have from the sheet.
I really hope there is someone who will help me whit the calulations
