RS Machines Pistons
I've tried contacting RS Machines a couple times now with no response.
I'm trying to find out the compression height and dome cc for their pistons, specifically the flat, domed, and ITR pistons.
With respect to the ITR piston, is it a copy of the JDM ITR piston, or the USDM ITR piston?
Thanks in advance.

Re: RS Machines Pistons
I've been using the Zeal Autowerks calculator.
B17, 82mm bore with a P72 head.
JDM ITR = 11.53:1
USDM ITR = 10.97:1
JDM B16 = 11.47:1
USDM B16 = 11.24:1

Re: RS Machines Pistons
why you dont try nippon racing pistons, i believe they are replicas of jdm itr's, and their products are not that expensive and hey they are also proven....i have heard bad reviews from rs machine customer service....

Re: RS Machines Pistons
nothing against rs machines, i had a block sleeved by them a few years ago but you should try the nippon or ycp pistons. to tell you the truth i wouldnt be surprised if they all come from teh same manufacture but just slap a different brand name on the box. the ycps and nippons can be had for a hundred bucks less sometimes

Re: RS Machines Pistons
Did two builds with RS pistons, neither with a problem
And this is the first I heard of RS having any problems and they've been "proven" many times to be adequate

Re: RS Machines Pistons
Zeal has some cool "more precise" features but I find the C-speed racing calculator to be more accurate if you will. They are all guides really and work off of assumptions, you'll find that when you start measuring things that actual dimesnions will be different than some of the assumptions.

Re: RS Machines Pistons
How are the RS ITR replicas what I want if I'm aiming for 11.5:1?
I'll have to look in to this. If they are in fact JDM ITR copies, they will likely be the piston I go with.
I currently have a C1 with RS ITR pistons...no problems what so ever.
Good to know.
Thanks for all the help guys.

Re: RS Machines Pistons
RS machine ONLY makes copies of USDM pistons. Thats why they dont sell P30's, Just PR3's.
The stamp on the ITR pistons is P73-A0.
OP if you cant find the JDM ITR's I know you can get the P30's in up to a 81.5 bore on JHPUSA.com which will be the closest to the JDM ITR slugs CR.
