Product Description

The NEW WR 1925S Engine Kit

Customers building our base 1925cc engines using WR91mm Durbar cylinders and lightweight CP pistons have been asking for a more aggressive S version of this smooth running big bore engine. The answer is the new WR 1925S. It uses the same WR Big Valve Heads and WR78 high lift camshaft of the popular WR2.2, but has the standard 74mm stroke and works well with the stock 356SC/912 counterweighted crank. This particular kit also uses special lightweight Carrillo rods with standard 53mm big ends but with a lightweight 19mm pin (a kit for standard Porsche rods is also available). The power band is smooth and pulls easily to the 6500 rpm redline. The kit is complete with all the critical parts you need. Everything is made to work together for a strong and reliable engine that requires no dialing in or adjusting.

Power output of the WR 1925S is shown in the attached graph compared to a standard 1925 with our WR Stock Heads and milder WR68 camshaft. Testing was done on our in house Superflow 902S dyno with a stock exhaust.
