CAMbiar mi CAM
I have a used performance cam and I'm thinking about using it. I know when going with a new cam, you need rocker arms / rocker guides, will putting new rockers / guides on a used came work out OK? What about springs? I've also heard to only use Nissan rockers. These aren't cheap. Anyone have any leads on good prices / good alternatives / suggestions?

If your new-to-that-head cam is at all more "aggressive" than the stock cam (greater lift and/or duration), then you run the risk of valve float at higher rpms if you use your stock springs. And of course on an interference engine like the S30 L series, that could mean damaged valvesHow much risk depends of course on how radical the cam is and what the current springs are like. Personally, I wouldn't risk it. I'd get a full valve job, new rockers, lash pads and springs. The MSA kit is about $550. While they're sometimes more expensive than some other suppliers, that's still relatively cheap compared to repairs if you have a cam install go wrong. Of course, that's the start of the "while you're at it" road, which means porting and polishing, too . I don't know about having to use Nissan only rockers, but I've not used anyone else's. Anybody else here have some info on that?
good luck,
Dave

Thanks Dave - just thinking a bit here this morning and wondering if it would be worth the trouble to go with the hot cam. I had heard that the Nissan rockers are about the best and that in some of my reading others have had problems with other brands??? Thanks for the info!!

These will grind down your cam in a heartbeat. literally.
The pad metal on the Nissan rocker arms is high quality.
