Texas Speed & Performance's turn-key engine packages are your solution for powerful, durable, and trouble-free late-model LSx power plants for your muscle car or hot rod! Each package is precision machined with state-of-the-art CNC equipment that allow for the strictest of tolerances, and every TSP engine is hand-assembled by experts that deal ONLY with LSx-based engines! All of our engine machining and assembly, as well as our cylinder head production, is in-house and NOT sourced out. All components in our engines are brand new parts, including the block, so you are not buying an engine that uses any remanufactured items! We are the only LSx-based company that digitizes and blueprints every engine block on a CNC machine to the factory GM specifications! Our turn-key packages are designed to provide our customers with a true drop-in engine that is ready to run! These are not stock crate engines that have been slightly modified. These are hand-built engines that have received the care and attention that you should expect when purchasing an engine! Our engines are built for strength, durability, and power, so your new TSP turn-key engine is ready for whatever you can throw at it!

The TSP 408 CID 620 HP LQ9 Turn-Key Package will have a lopey idle and will require a minimum of 2,800 RPM stall speed torque converter for automatic-equipped vehicles.

All of our TSP turn key engines will include a Holley Terminator X Max engine management system with transmission control.. Terminator X Max features real-time fuel learn, high impedance injector drivers, an integrated 1bar MAP sensor, and 4 programmable inputs and outputs. The inputs and outputs are ideal for electric fans, boost control solenoids, progressive nitrous control, and much more. The 3.5" touch screen LCD handheld contains an easy to use calibration wizard as well as tuning and gauge display functions. Also included is Holley EFI's industry-leading, easy to use software suite that allows full laptop access for advanced users.

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!
