I've been searching this for about an hour and coming up with to much info but no answers

What I found was either Wiseco pistons or JE pistons.

Wiseco has different sizes and I need to sleeve my engine so should I just go 20 over with the 8.8 CR or keep it standard with 8.8 or what? What does going 20 over give your engine?

JE pistons were 9 CR and thats about what I should have with my thicker headgasket. I don't want to lose any power. Would a .2 CR make a big difference?

Thanks...

 

Most aftermarket piston for F20/F22 will not work with FRM Sleeves.
I think only TODA made piston for our engine that doesn't required to resleeves.

 

I'm getting Darton sleeves.

 

im running cp pistons

 

 

ok but is it worth going 20 over and since I'm getting it sleeved?

 

you can buy stock bore pistons from cp. i didnt go 20 over just incase i have to build the motor again

 

Yes it is worth it, more displacement.

 

I have stock bore pistons from Arias. They're 9.5:1 compression ratio. I'm running the stock bore because I wanted more wall thickness between the cylinders due to the turbo and the ability to bore out the sleeves later if necessary.

OK thanks for your input,

One last question though,
How much horsepower will I lose going from a 9:1 compression to 8.8:1?

Thanks
