i want to help my delsol out a little by putting my old ls cams on this b20b cause i was told the diff. in the b20b an b20z is in the cams. but then i found the receipt from my motor supplier and everyting is in kilometers and it says b20b jdm but is there any way to tell for sure that i have the jdm block that is equal to our b20z?

thanks

 

usually jdm engines dont have a # at the end of the engine code..for example jdm b18c, usdm b18c1

 

i did some more research but now in even more lost lol i found out that the higher compression blocks have a knock sensor above the oil filter but mine dose not. then i find out that there is a 3rd b20! a are b20 with a more agresseive head (p8r) well my luck hits cause i have this rare block but still dont kno the compression ratio
