I am running 10:1 compression pistons in a fully built closed deck sleeved GSR and am going to run around 28 pounds of boost when I get dynoed next week, I have already ran it at 20 pounds of boost and made 500WHP with no problems, as long as your block is built right your can easily run 10 pounds of boost on 10:6:1 compression.

Fairly stock as in stock sleeves, you should still be OK.

You can.
Don't Run crazy boost and get a good tune and you should be safe.

did 300whp on my stock sleeves on 11psi with the LS/V a long time ago. Its fine, just have Joe At locash tune it :)

GSR turbos on 10psi make good power safetly all the time

Eh the LSV got a few runs, 12.7 at 121mph on Azenis. Not fantastic but traction was a mite of an issue.

Keep in mind the times will have alot to do with how the turbo lays out the powerband. (not all 10psi cars are the same basically).

I personally wouldn't every buy a used Stock built honda lol. Who knows how its been treated!
