Engine Builds and Parts

We have made it easier for you if you plan on building up your engine and want to make sure you have all of the parts needed before you start. This kit is all of the basic parts needed when doing engine work on a LNF 2.0L engine. These are the same parts that we replace when doing engine builds here and we have grouped them together to make it easier for you to order if you plan on building up your 2.0L for more power. Universal 2.0L engine build kit includes Timing chain tensioner, Rear main seal, Timing Cover gasket, Main Bolts, Girdle bolts, Main OEM bearings, Rod bearings, Head gasket and ARP Head studs.

FITS: 2015-2019 Polaris Slingshot. No cores, no mess, we only offer brand new valve covers direct from GM that are carefully prepped and powdercoated in your choice of color, this even includes a new valve cover gasket! We have brand new valve cover cores come in and then carefully prepare each one for the powder coating process.

The skirt shape (barrel/cam) is one of the most functional areas on the piston, and provides stability and smooth operation in the cylinder bore. Stability is important for proper ring seal, reduced friction, and quiet operation. Each skirt shape is designed for a specific running clearance, based on coefficient of thermal expansion of the piston alloy. Some forging alloys expand more than casting alloys, but each Wiseco piston is designed with the proper installed clearance to produce the most power, least wear, and best seal at running temperature, for each application. Comparing installed clearances on cast vs forged parts is not indicative of the running clearance at temperature. Wiseco engineers have a strong background in all forms of racing applications, and produce the best shapes and designs in the industry.

Bore size notes - Stock bores can wear slightly over time which can result in too much piston to cylinder wall clearance. At our shop we prefer to use .5mm larger pistons which require a slight overbore on the sleeves but bore the cylinders to match the pistons exactly and keep the piston to wall clearance in the specified range.

Compression ratio notes - Lower compression rates are available through custom order, however lower compression ratios are not needed for most builds.
