All TSP engines will include 12 quarts of Joe Gibbs break-in oil for no additional cost. Proper break-in oil and procedures for your engine are just as important as the build process! The Joe Gibbs break-in oil allows for proper ring sealing against the cylinder walls upon start-up, as well as for the break-in period once the engine is up and running. Most off-the-shelf engine oils do not have the necessary ZDDP additives to allow for proper break-in of a new engine, and we want to take every precaution possible to ensure that your new TSP engine receives a proper break-in!

Texas Speed & Performance offers the best short-block, long-block, and turn-key LS-based engine packages on the market! You will not find another in-house facility that is more dedicated to building a quality engine, nor will you find another facility that uses the same state-of-the-art equipment that we do. We encourage all of our customers to take a few minutes to research where and who your engine is coming from! Many facilities do not machine or build their engines in-house, and you also need to see how their facility is run to have an idea what goes into your engine. The TSP cylinder head and engine machining center uses the latest state-of-the-art equipment to machine the best engine possible, and every TSP engine is assembled in our climate-controlled clean room! If you cannot visit a facility in person, ask for a virtual tour! We offer a virtual tour of our machining center, as well as our complete facility, so customers can see how much dedication, expertise, and technology go into their engine. You are buying this dedication, expertise, and technology from a company that only specializes in LSx engines when you purchase a Texas Speed & Performance engine!
