I was told that the new 05' RSX-S comes with an extra 5hp. I was also told that these gains come from changes to the head. Can anyone confirm or deny this, or provide any info concerning the changes made? Thanks in Advance!

 

Change on the cams, heads are identical.

 

I have no proof but speculations about the cylinder head. Here is a more complete list of information about the car.

whats the difference between a type s and type r k20 head???are the head stamped same code??

 

Its a 10hp and 1 ft/lb of tq difference. Comes from: Pistons, cams, intake mani. I believe the head casting is the same.

 

please more info if the head stamp is same or different
