Any Wiseco piston set will use a 3.903" bore piston. Other custom build items are available. We also offer Lunati and Oliver connecting rods. 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 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!

All Wiseco pistons will use a 1.2mm/1.2mm/3.0mm ring pack with a steel top ring and Napier second ring. This will be the standard ring pack used with any of our Wiseco exclusive piston sets, and this ring pack will be offered with any Wiseco off-the-shelf piston set. All Wiseco piston sets will use the Wiseco/NPR-specific ring sets. We do build many engines to keep in stock, and we do our best to offer a variety to suit everyone’s wants/needs. With that said, not all engines will be in stock. The average build time will normally take three to four weeks once all parts are at the machine shop. This is only an estimate since circumstances and wait times will vary. Please give us a call for an accurate, up-to-date time quote.

If you are planning to use a power-adder and exceed 12 psi of boost or a 200 HP shot of nitrous, we would recommend building a 4.00" stroke engine since it will allow for a thicker crown on the piston. All of our engines with Wiseco pistons will use a Napier second ring for maximum oil control. This is just another step that we take with all TSP short-blocks to ensure you get the best quality possible! We also offer an expedite service to be able to have your engine built and ready to ship in as little as five business days! The build time will vary according to parts availability. Give us a call for more information!

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!
