If you’ve ever built an engine, or had an engine built, you’ve likely suffered through trying to find pistons. Pistons are one of the most technically complex parts of an engine recipe, and trying to determine the correct pistons for your build is a mix of application, experience, math, availability, and even your own engine builder’s preference. Even when you settle on a certain brand of piston that you may like more than others (here at Flag we’re big fans of Mahle and CP Carrillo) it can still be difficult to narrow in on the exact piston you want for your build. This is because many website catalogs are clunky, filtering options are sometimes mismarked, and important factors like cylinder head CC, target compression ratio, and head gasket thickness are static and not dynamic in said catalogs. This means a lot of math has to be done behind the scenes once you find a piston you think will work to make sure that it will actually work in your specific build. Well, we got sick of browsing ecommerce stores with poor filtering, catalog referencing, and compression ratio calculators, and built our own tool to help you find the pistons you need, and a range of any other workable options in case there are stocking issues, parts are backordered, you need pistons yesterday, the normal hurdles in the industry.
Introducing, the Piston finder. This tool is currently loaded with the CP Carrillo catalog, with more product lines coming in the future.
Verify you are human with the captcha, and then work through selecting the type, engine family, and engine specifics for the pistons you want. At the end, you’ll see the full list of any matching part numbers that would work for your build that exist within CP Carrillo’s piston catalog - with data calculated for your exact input specifications. Once you have the information you need, you are welcome to purchase the pistons through us, as we offer free nationwide shipping and typically stock common LS/LT piston part numbers. Please also feel free to share this tool with friends and fellow engine builders with the hope that it helps anyone navigate the piston selection process.
