Default QUESTION ABOUT LS/VTEC TURBO PISTONS HELP!!!

I had a prior post but it just disappeared so I am reposting. I have decided to go turbo instead of NA so now I need to know what pistons to use. I know to use forged internals So do I buy forged LS rods with LS pistons or forged LS rods with VTEC pistons? I have searched and have been told both I was told by a member here on Honda tech to use the LS rods and LS pistons and then I was also told to use LS rods with VTEC pistons from a search I had done on Google. Looking to run 10-12 psi on stock sleeves at 9.0:1 comp. I am sorry to be repetitive but I am lost on what to use. Let me know what you are running thanks again and foe dealing with a pain in the ***.

For the 3rd time......

Aftermarket pistons and rods of your choice for an LS if you are using an LS block and crank.

Does the compression ratio of the pistons in general matter because i know when you are looking at pistons they say 9.0:1 compression ratio but this is for the motor they are intended to go in like an LS per say you put a 9.0:1 LS pistons in an LS/vtec what would I expect due to the vtec head giving more compression.

an lsvtec setup will raise your compression around .5-1.0 compression points over an ls motor depending on gsr or b16 head and how much mill/deck you do during rebuild.

i used to use the wiseco 81.5 mm 9:1 compression

GSR pistons / ls rods

ls pistons have a different size valve relief.

also 9:1-10:1 is fine for CR
