I was wondering which type of compression of piston i should get with my 2.2L with stage 2 cams and all the mods in my sig? Im taking any suggestion on which ratio i should run

 

Are you going to get tuned and/or go with forced induction.

If you aren't doing forced induction and can get a tune go with 10.5 CR

 

ok so 10.5? or is that 10:5.1? If i was going forced induction go with 9:5.1?

 

Yep exactly. Stock compression is 10:1 but if you can get a tune 10.5:1 would be nice.

I think the best bet is 10.5:1 with a little nitrous for good 2.2 power.

 

Which company sells that ratios of piston?

 

Well based on your debadging and painted calipers I would say go with a 10.5:1 or 11.0:1.

Seriously though if your gonna stay NA the only piston worth paying the money and time to swap to is an 11.0:1 Your gonna need to stick to a diet of premium fuel though. IMO 10.5's are a waste since its only half a point of CR and it may not even be that once you take into account head gasket thickness, etc... If theres any chance youll go forced induction just got a forged stock replacement(10.0:1)

You can get custom pistons from just about anybody that makes pistons for the L61 but I personally like JE, and know that they will make you whatever you want for about $150-170 per piston including rings, pins and locks.

 

i went turbo and mine are 9.0:1

 

You might see 2-3 HP from going from the stock 10:1 to 10.5:1 pistons, IMO it is not worth all the extra $ and time to custom build a set....

10:1 is for N/A and the 9:1 is for the FI/nitrous setups....
