TSP Boost 5.3 Long-Block

Texas Speed's newest long-block in the lineup! The Boost 5.3! This engine comes standard with a new Gen III GM 5.3L aluminum block, Johnson 2110R Lifters, PRC As-Cast 220cc Heads, new GM crank, TSP exclusive H-Beam rods with ARP 2000 rod bolts, and TSP exclusive "Big Boost" 3.820" bore pistons that we developed with Wiseco! The GM 5.3L aluminum engine block is a very popular choice for those looking to build on a budget and handle a great deal of horsepower. It has excellent benefits, such as bay-to-bay breathing, that make it very durable to use in the build. The 3.820" bore allows for larger-than-stock valve sizes but no valve reliefs to create the most detonation-resistant/bulletproof pistons possible! This engine will come with the cam of your choice and our PRC 220cc As-Cast Cylinder Heads! All of the TSP truck camshafts and LS1/6 camshafts up to our MS4 will clear with factory-thickness head gaskets and unmilled cylinder heads. Be sure to check out our 4.8/5.3 turbo cams as well!

Custom builds are available. We offer multiple brands of connecting rods and crankshafts to suit any type of application. Every engine will come standard with the necessary oil and coolant plugs already installed in the block. Feel free to give us a call, and we will be more than happy to put an itemized estimate together for you! We also offer additional discounts if you pay via a cashier's check or wire transfer. All engines will ship via truck freight, so if you are purchasing online the shipping costs listed will NOT be correct! We will contact you with a shipping cost after your order has been placed. All prices listed do not include the applicable shipping costs!

We do offer an upgrade to 1/2" head studs for those looking to run a large amount of boost. The price listed for the 1/2" head stud upgrade will include the cost of the ARP hardware, as well as the necessary machine work. All of the PRC aftermarket casting cylinder heads already have the larger bolt holes to accommodate 1/2" head studs.

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.
