we have a boosted d16y7 that just messedup the piston rings

and we have vitara pistons here that we were going to throw in a d16z6 for a crx

if we put these pistons in the y7 with the oem headgasket it makes a 7.59:1 compression ratio i think this will casue issues ideling from what i can find but does any one have any input on this? has any one run any thing this low before?

or would it be a better idea for us just to replace the rings on the stock p2e pistons?

7.5:1 is incredible low when not in boost its gonna have the power and response of a lawnmower. You can always compensate with like 40psi. That low of compression will have a bad effect on the motors efficency. Shoot for 8.5-9:1.

ok cool i guess ill use the stock pistons and just get new rings and eagle rods

are there any rings that can handel more stress then stock??

Several people on here have posted Vitara setups and said they're not bad at all to drive off boost. I know one guy on here has a turbo ZC in a CRX or an EF Hatch that's about 7.5:1 and said off boost driving is fine. I've driven a hatch with an 8.0:1 D16Y8 and it wasn't even that bad either. Run the vitaras, they're proven to make power and it would be a total waste to run stock pistons on eagle rods.
