TSP 376 CID 556 HP LSA Turn-Key Package - TSP-25-TSPLSATK556
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 376 CID 556 HP LSA Turn-Key Package will have a smooth idle. This package will include the following items:
GM LSA 6.2L Crate Engine

The TSP turn-key LSA engine packages will include a GMPP engine harness and a GM ECM as standard to allow for full engine control and the best driving characteristics possible. Most other suppliers of turn-key engine packages will use out-of-date MEFI ECM's and harnesses that do NOT allow the engine to make fueling or timing changes when running, nor will they allow for any needed changes with varying altitude. The TSP turn-key engine packages will allow your engine to run and function exactly like a new car straight off of the production line! This will not only help the power output, but it will also help to maximize the fuel mileage! Our optional custom-built harness will also allow for full control of GM's 6-speed overdrive 6L90E electronically-controlled transmission. We can have your harness custom-built to allow for transmission control, so you will not have to spend $1,200+ on a stand-alone transmission controller! The competition's MEFI ECM and harness does not have this capability.
If you select the custom Speartech engine harness and controller, it will also include the factory 2009+ Cadillac CTS-V fuel pump assembly and leveler for the fuel sender. So, you will need a custom fuel tank that will allow you to use these items. The LSA engine has three MAP sensors from the factory, and both the GMPP harness and custom harness will utilize all three MAP sensors. This will offer stock-like driving characteristics, as well as maximum performance and fuel economy! The GMPP engine controller will not have any provisions for controlling a transmission.
Our LSA turn-key engine packages will come standard with the factory GM LSA valve covers since they offer excellent baffling and breathing. Let us know if you are looking for an item that is not listed, and we will be glad to provide you with a price! The billet aluminum coil pack relocation kit allows you to hide the ignition coil packs anywhere you would like under the hood, which provides you with a clean and uncluttered engine bay.
All Texas Speed & Performance turn-key engine packages will come standard with a one-year, unlimited-mile warranty as standard! This will require all tuning to be performed by us. 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 Driven Racing 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 Driven Racing 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 the Driven Racing oil for your new engine once your break-in is complete. We recommend using either the HR2 conventional non-synthetic or the LS30 full synthetic oil. Please note that the Driven Racing LS30 is the ONLY synthetic oil we recommend using in your engine because it retains the necessary ZDDP additives.
*Optional powder coated supercharger top shown in pictures. Standard package will include the GM cast-aluminum supercharger top.
Lethal Performance is proud to offer the entire line of products!
