if i'm not mistaken, the comptech charger will be sweet as on stock F20C compression, which should be around 11.7 for JDM engines..... with the spoon headgasket, it'll probably be up to 12.1....

would it be ok to chuck in a supercharger kit like comp tech etc after that?? or would the compression be too high?? anyone with comptech chargers got a high compression head gasket???

 

Moving to F.I.

 

You're not gonna wanna do that. The fuel management system wasn;t desinged for compression higher than stock. There's no advantage to raising compression other than to say you did it. Run EMS and higher boost instead.
