Send a pm to Peter Zekert, he may still have some roller rockers for sale and the 1.6/1 ratio work great in my A14 and are a straight ' bolt in '.A quality item much nicer than the stock units.

The best rocker arm assembly is the stock one. Except for extra high-RPM, you need to fit solid bushings to replaces the shaft springs.


Rocker assembly


The roller rockers have problems ...

The Nismo high-ratio rockers are OK, if you need that.

Beware of overtightening the rocker shaft bolts.

Whoa hold off the capslock Webbs. There's a couple of options I know of like the standard rockers with thier 1.4 ratio (is it that?) or get a set of GX rocker arms with a zippier ratio.There's also aftermarket rockers over there with different ratio arms and some with roller tips.

My A14 with the above traits I've retained the standard rocker ratio but replaced the retaining springs with the machined collars available through B Projects, they prevent the rockers from sliding off their valve at high RPM and they keep a small pocket of oil around the shaft underneath them.

If that's not going to cut it then you'd best be lightening your wallet on a set of Yella Terra Roller rockers and finding a suitable pushrod to fit the kit, I understand the common one is a small block chev item.

Which way you go should depend on what your using this motor for and how hard like Autocrossing or something?
