I am having trouble locating the correct piston for my setup.

-B18C Darton MID sleeved to 85mm
-Eagle 5.433 H-beam rods (stock ITR length)
-Stock ITR Crank

It is very possible I am thinking to hard on this one. Essentially this engine is just a bored out ITR. The reason I am getting confused is because every piston catalog I look at refers to all the 84mm+ pistons as having to be used with 89mm stroke and a 5.290 rod. But the more I think of it, aren't the pin location in all B series pistons the same? (excluding long rod setups like Endyn). Basically what I need is a 12.2-12.5:1 coated piston. But I want to make sure I order the right piston.

Sorry if a fubard your brain reading this junk. Maybe some of your more experienced 2.0L builders can chime in. And while were on the subject, I'll take some suggestions on a set of camshafts that will get me in the 230whp range.

Thank you all for your time!

I was also thinking about a 85mm or 86mm on a 87.2mm crank but ran into the same issue you are having. Not much support in that range.

 

Arias, JE, Wiseco all have 85mm bore with various CR's to choose from

 

I forgot all about JE Pistons, and judging by their catalog, the piston does not care what stroke or rod length is. Because if you look at the part number for B20 pistons and B18C pistons for the same bore and CR they are the same, so this in turn answers my question.
THANK YOU.

 

Thank you, I know this, my confusion was where they say you have to use 89mm stroke. But my questions are all answered now, thank both of your for you time and support. hehe
