Hi guys
Im looking into building up an h22 to run boost of about 10-15PSI. Im going to sleeve the block using Darton Sleeves however I dont want the compression to be too low as I shall be using it on the street. What compression pistons do people recommend I go for?

Thanks

 

Cp's 9.0 or Je's 9.1 would work great..

 

I run 9.0:1 with all of the H series build ups I do.

Go wich CP's as stated previously.

 

I agree with Anthony and Adi that you ought to go with 9.0:1 Compression on a street application. We have sleeved (Darton) and built alot of H22 solid deck and open deck blocks and I have to say that we have had the best results with JE in reference to install and performance.

 

darton sleeves and JE 9:1 is what i run....

 

Don't get caught up in the "you gotta run 10:1 or higher to have a great street car" fad. 9:1 works great for most people. I'm running 8:1 in a dinky D-series and I'm driving it naturally aspirated with no issues right now.

 

Thanks for the replies guys, thats why i asked the question cuz I'd heard those rumours anythings possible eh!
Thanks again
