just wondering if anyone knows how you can identify the difference between an H22 (Base) and an H22 (Type S)??

Is there a prime way to identify the difference??

 

USDM pistons "US" = "imprinted on top: P5M with 10.0 compression"
JDM pistons "Japan & europe" = "IMprinted on top: P13 with 10.6 compression"
Type S pistons "Japan"= "Imprinted on Top P5P with 11.1 compression"

Regards,

how do you tell if the heads on

 

I dunno how to diffrentiate between the JDM & the USDM, but the TYPE S has a RED VALVE COVER

 

that dose not help at all

 

IIRC the JDM H22A Type S has P5P stamped on the head as well and the USDM have P13 or P5M stamped on them.

 

thats good to know thanks
