Introducing the NEW 4P TR2.5 racing camshaft!! 4 Piston continually develops and pushes for improvements across every platform. This new camshaft is a direct result of that constant push for improvement. Our TR2 Drop-In cam changed the game making it easy for gains on simple setups, and our TR3 proved to be a great racing camshaft for racing engines with standalone ECUs like Motec. The TR2.5 gives you those BIG TR3 gains, but in a design that works great with Hondata!!
- Easily tunable with Hondata
- 20-30hp over 4P TR2 Camshafts, 60+hp over stock!
- Better Street manners, less noise, more power!!
- More aggressive VTEC POP...the thing that made us all fall in love with Honda engines
- TR3/Motec type power for Hondata programmed vehicles
- Improved High Durability Camshaft Cores
Gains of 60+hp are realized through the RPM range, and more as you continue to pull beyond 8000 rpm. Camshafts are supplied with cam card and VTC limiting pins with detailed photo for their placement.
