I need help with Mahle Pistons(H22A).
Ok, I found what I was looking at:
The GoldSeries H22 Piston Kit includes:
- 22mm High quality steel wrist pins
- Round wire locks
- Available in: Flat Top, High Comp Dome, or in supercharger, turbo, or nitrous ready Inverted Dome.
- Precision ring grooves for 1.2, 1.2, 2.8mm rings included.
My car is going to be a weekend DD. Do I want Flat Top, High Comp Dome?? I have no clue as to what these are suppose to do. Some advice and tips are appreciated.
Also,
I found the spec I wanted for my High CR pistons.
My Concern:
The piston vol. off the Mahle pistons=10cc
The piston vol. off the stock pistons(JDM H22A)=1.9cc
So I wonder if they ever fixed the issue about the valve relief that they were having a few years ago?? Thats why I brought up those concerns of mine since the numbers are sort of different.
