I am learning a lot about this SR20 set-up, and I am again asking for some help for anyone that has info on the rocker arms. I am working on building the best power plant I can put together for this car. It has come to my attention that the rocker arms seem to want to break.

So, we are building him a new motor because the first engine broke a piston, (it was bought that way) and we bought a junk yard engine to put in so he could drive it. He was in town on a 30 day leave and just flew out this morning. Two days ago, him and his brother decide to "get on it" and well they did, over rev'ed it and broke two rocker arms.

I see where "rocker arm stoppers" are used, I assume, to prevent the rocker arms from breaking, but is there an aftermarket rocker arm that is more durable? and less likely to break? I did a search, but nothing came up about it.

Now that I have the bottom end somewhat under way, I was going to start on the head work soon. He's gone for quite some time now, so I have months to put this together.

Thanks for the help in advance!

Anyone?

If everyone is using the OEM rocker arm, which manufacturer of the stop springs seems to be the best?

Thanks for your opinion.
