Tech Works Engineering News

Press Release 08-01-03

Calgary, Alberta

Tech Works Engineering Inc. (TWE) has announced the release of their high-lift valve springs and titanium retainers for Subaru’s SOHC and DOHC 2.5L engines. Built to TWE’s design specifications, the SOHC kit complements TWE’s Stage II Street/Rally Camshafts. Maximum safe lift pressure has been increased by 60%, allowing for lifts of well over 0.060”and eliminating the danger of coil bind. A 25% increase in seat pressure ensures sealing with forced air applications. The titanium retainers, also built to TWE’s specifications are almost half of the weight of the stock pieces, reducing valve-train weight by over 12 grams per valve (with springs). All parts are available now, for both SOHC and DOHC EJ25 applications, and are sold in kits or separately.

Another bolt-on solution for your Subaru from TWE. For further information contact sales@techworkseng.com.
