On my SIR-G my current set up is:

AEM CAI
High flow cat
Apexi N1 exhaust
DC JDM 4-1 header
Fidanza 7lb flywheel
Exedy Organic clutch
VAFC2
FPR

Before the flywheel and clutch the car was running 14.6-14.7 at best . My goal for this season is to hopefully get a 13.7-13.9 out of the car. Since I already have just about all the bolt ons except Skunk IM, im trying to decide what internal set up to go with. The car is a daily driver so i need to keep it as reliable as possible while at the same time making as much power as possible to reach my goal.

My options for cams are CTRs or Skunk1s
Pistons can CTRs but based on what I have read JDM ITRs may be a better choice for me.

Out of my options listed, what seems to be the better choice to get me where I wanna be ?
