VTC Actuator and Cam Questions
VTC Actuator and Cam Questions
I have an '07 Civic SI and I'm planning on installing mild/street cams and tuning with flashpro. I have heard some rumors about needing to change or modify the VTC actuator on the intake cam to accommodate the higher lift so there's no piston to valve contact. I've also seen companies like King Motorsports offering them for sale. Is this a necessity or is it only for more aggressive cam profiles?
Re: VTC Actuator and Cam Questions
You will have to talk to the cam manufacturer about this as it all depends on how much lift and how the rest of the engine is built.
