All Texas Speed & Performance turn-key engine packages will come standard with a one-year, unlimited-mile warranty as standard!  We stand behind our work, and when you purchase a Texas Speed & Performance engine you are not only buying the parts but also the knowledge, experience, and know-how!  We have completed many LSx-based engine retrofits at our facility, and we KNOW what works and what is required to complete the installation!

We do recommend verifying the necessary clearances for both the front drive accessories and the oil pan kit.  The kits that we have listed work with the majority of setups, but every car does vary!  It is the customer's responsibility to verify these measurements BEFORE placing the order.  Once these items are installed on your engine and shipped out, they are not returnable.  Feel free to give us a call to discuss your setup with us, and we will be glad to assist you in determining what your vehicle will require!

All TSP engines will include 12 quarts of 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 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! We also offer Driven Racing oil for your new engine once your break-in is complete. We recommend using the HR2 conventional non-synthetic.
