The NEW WR 1925S Engine Kit

Now with our new WR Alloy/NSC Cylinders

The newest version of our smooth running 1925S has now been upgraded with our own Alloy/NSC Cylinders. NSC stands for Nickel/Silicone/Carbide which is the US version of Mahle's Nikasil plating. Much harder than cast iron and significantly cooler running, these new cylinders are quiet, reduce weight and increase performance. 

The 1925S uses the same WR Big Valve Heads and WR78 camshaft as our 2.2 liter engine. The power band pulls readily to the 6500 rpm red line. No flat spots or peaky performance, this is a fully engineered kit which includes everything you need to build a bulletproof engine that is a dramatic improvement over the standard 1720cc big bore. Comes with a full HD gasket kit, 5 row oil cooler, head studs, alloy pushrods, HD gland nut, sport air filters and our newest 44IDF Webers with WR linkage, phenolic insulators and our exclusive 5th transition port for smooth mid rpm driving.

New dyno test results will be available soon!
