I'm not sure but you might have to get the pistons machined. The pin holes.
Check your Comp/Ratio here. http://www.c-speedracing.com/h...c.php

 

they fit fine. i've used them myself. the machine shop will PRESS them on for you, no modifications required.

compression will be around 11-5

 

yes they fit

 

Don't you have to mill 1mm off the ls rods like an lsvtec setup?

 

LS and B16a rods are the same width at the pin. no need to do any mods for the piston to be pressed onto the LS rod. same with Rod bearings for the LS and B16a....they are the same width in case you wanted to know

 

Yep, PR3, PR4, P30, and P61 pistons all fit without shaving the rods.

No. That's only for PCT and P73 pistons (maybe P72's as well, I can't remember).

 

I verify PR3 pistons go directly on LS rods, just press off and on. R pistons you do have to mill 1mm on each side of the rod. Had experience with both.....
