Duno, iv always heard they're a must for any SR20??
I'v them on mine and i wouldnt drive the car on track without them! mines VVT
Yeah various valve timing it just says with with some rocker stoppers wont work with vvl i gather there tlking about vvt just another way ppl have saying it.??
VVT (Variable Valve Timing) = http://en.wikipedia.org/wiki/Variable_valve_timing
VVL (Nissan Variable Valve Lift and Timing) = http://en.wikipedia.org/wiki/VVL
basically, VVL is a further development on VVT (like Honda's VTEC), where not only does it change the timing but it also alters the lift the valves go through changing how much fuel/air gets in (or exhaust gases out) with each valve lift
greddy rocker arm stoppers are available for vvt s14/15 as far as I know.
I would deafo fit them at the stage your engine is at ie OUT of the car being built!
Thanks rancido that explains a lot now how do i know for sure it is vvl or vvt i have?

they say they are not compatible with vvt,but all they mean is you have to modify the rocker cover to fit them.its an easy 10 min job
