I would say i dont mean to hijack your post but i just spoke to my supplier for CP Pistons he said if we can get 10 sets i can get them for $1100 if its individual sets then $1250 Pistons pins rings locks. 5 - 6 weeks. we all know how good CP pistons are ... nick from APC is now making around 950hp atw with gas in his evo on cp pistons.

hey guys i`ll let you in on a trade secret, just use the galant vr4/evo pattern cp forgies as the smooth dished piston crown will help prevent detonation.. Ring widths are better 2, much less likely 2 crack ring lands. they only cost $760 including rings etc last set i bought. or u can just use vr4 pattern hypatech`s for about $300 which i`ve been running in my car for 30000k`s with 20 psi no problems. Dont believe everything ppl say, u dont need forgies if ur running over 15psi. maybe 30psi is a different story.......

the reason the standard pistons have valve reliefs is so the valves wont contact the pistons if the timing belt breaks.. they call it `free spinning` in the trade,some engines do, most dont. obviously its a downside of havin the twincam style pistons whereby they will clash if it breaks. i say just remember 2 replace your timing belt when ur supposed 2! and also if u ever decide 2 change 2 a twincam head in future u dont have 2 change pistons aswell. and no, we have no clearance issues in 84KIT it all came together nice.. maybe if u had MASSIVE lift u might need 2 fly cut them. Have a few cars running around with this setup its the best thing since sliced bread i cant recommend it highly enough..... they`re a shitload less likely 2 ping and if they do they`re less likely 2 break rings or crack pistons

Are you talking about using the Sigma Astron motor Cam in the Sirius 4G63 ??? No go bro , different engine . If you just mean the same grind on a 4G63 cam , again being very different engines it may , but won't necessarily , work .
The standard Starion cams are actually very large and are already capable of 7500rpm . Practically every strong motor I've seen has used the standard one or close to standard but with more LIFT . That's what I'd advise .
I know of guys who've tried bigger cams and have always gone back to a standard or near standard grind . Some guys in Japan used to use cams with SMALLER duration but much higher lift and then offset it with a huge Turbo . If you can find someone with a PROVEN cam grind in an engine setup similar to yours then go for it but otherwise again stock or stock duration with .5 - 1mm higher lift but watch your piston clearances .
