The 99-00 b20b has 9.6:1 C/R. 146 hp and 133 ft-lbs torque. <U>What would the compression be with the P8R head(honda orthia head) on a 99-00 spec b20b block?</U> <U>What headgasket would you use?</U> I heard p8r heads flow as good as the vtec heads due to the 33mm intake valves and bigger 84mm combustion chambers. <U>What size are the exhaust valves? 28mm?</U> <U>Also are the b20b 99-00 spec oem cams an upgrade in the p8r head? </U>Sorry with all the questions im just curious on this setup.

bump.

 

For the compression I think it's close, maybe 9:8 like a b18. Use a b20 gasket. The exhaust vlaves should be the same size as the b18. A lot of people put the b18 cams into the b20.

 

Most b20b come with the Ls head 81mm combustion chamber, but the p8r has an 84mm combustion chamber. I dont think the Ls headgasket would match, would it? Bump for some more info. What b18 are you talkin about??? b18b=9.2:1 b18c=10.0:1

ttt. Somebody's gotta know.

 

bump. WTF, come on honda-tech.

 

ok... im using a GSR head on a b20 and im runnin 13:1 compreshion with built rods i would guess a P8r head would run a 10:1 compreshion
