Starting in 2009, Wiseco will start using 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 as they make the change from their previous 1/16"/1/16"/3.0mm ring pack. We have the Wiseco and Diamond Racing piston sets listed under separate categories since there are different ring sets offered for each piston manufacturer. All Wiseco piston sets will use the Wiseco/NPR-specific ring sets, and all Diamond Racing piston sets will use an exclusive Total Seal ring set. The Diamond Racing piston sets will come standard with an exclusive TSP/Total Seal plasma moly/napier 2nd ring set, and a steel top/Napier 2nd ring set is available for an additional cost. We do build many engines to keep in stock, and we do our best to offer a variety to suit everyone’s wants/needs. If you are wanting to use our website to get an engine quote, select your desired piston and ring set and list the other piston and ring set as "do not want". So, if you want a Wiseco piston and ring set, select the appropriate parts and list the Diamond Racing pistons and rings as "Do Not Want" in the drop-down menus. 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.

For any nitrous setup exceeding a 150HP shot or any boosted application exceeding 10 psi, we recommend a steel top ring set. The steel top ring will handle the added heat of the nitrous and boosted applications much better than a plasma moly top ring set. Unless otherwise specified, our engines 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!

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!
