Hey Guys,
I threw a D16Z6 head on the D16Y7 engine that is in my '95 Coupe, on Sunday.
I did a compression test last night and recieved 188psi across the board. No variation, which was good to see, but lower than I expected.
So, my question: Does anyone know the piston dome/dish volume for the D16Y7(P2E) ?
Any feedback would be cool...

 

I'm not really familiar with SOHC numbers but no variation is great... P2E: compression height = 30.00mm, dish = 3.32mm... I actually still am working on a formula to convert CH and dish to "cc of dome" even though I'm not sure if it is possible... Those are the only numbers I have for your Y7 pistons but if you don't already have a way to convert then I'll work with yours since I have a known static compression... Peace

 

Well, I thought I would be over 200psi, but good to see the engine is good.
Given the complex shape of the dish, I think the only option is to 'cc' the dish, or find specs from Honda. Anyone done this?

3.32cc dish

 

That is the depression depth, not the volume...

 

cubic centimeters (cc) is a unit of volume and the p2e piston has a hole in it 3.22 cc in volume
