Finally going to get the ball rolling on this ongoing project of mine. With the 2nd (modding money) job I got I will have funds to put towards getting the car going. But back tho the subject. I am looking to purchase some pistons before the money in my wallet disappears. My question is which kind and what -cc should I get, which will best suit my application? Looking to run 14+ #'s (as much as injectors will let me) of boost. Straight kill mode no street mode :metal:!!!!
Also what cp ratio will I be at with stock casting vs 62cc off the self tfs heads. Look in sig for mods
3.480 eagle crank
5.7 eagle rods

There are too many factors for us to determine your CR. We would need to know the deck height on the motor, headgasket thickness, etc etc and whatever piston you decide.
Basically you need to pick a target CR and then we can work from there. the Piston dish can be figured out after we know what CR you want.
As for type of piston... depends on your budget... for a low budget SRP, Speedpro and some others will work, but if you have the money for it, JE or especially Diamonds will be very good under boost

I had srp but I got rid of them. Target cp is 9.0:1 or close to that. I am looking at some -24cc dished diamonds for know. I can go custom but we all know that is $$$$
