Yeah so I stepped on it merging with traffic at an intersection and went over some bumps that werent visible from the stop, the wheels skipped and I revved to or passed 8000rpms (as high as my tach goes) and nothing flew off. Thank god for rocker arm stoppers

How hard were those to put on? I would like the peace of mind of knowing that they are there.

they are east to put on. You need some grey silicon gasket maker, a gasket scraper, torque wrench, and the page from the Factory Service manual that shows the tightening order and torque values for the cam tower bolts.You need the gasket maker to re-seal the cam cover gasket around the half-circle shaped plugs.

Good link to install of RAS. This is on a S14 SR engine but basically lead you through the right direction. Go to the site for other Tech Installs that can help as well.

Thanks. Those installs will prove to be very helpful in the near future.

hmm.. i might have to go over everything. it seems to be leaking from the half moon side too. do you have to use a in/lbtorque wrench instead of a regular one? seems like the bigger one doesn't torque down that low. i just hand tighten them to "tight" since torque is so low.... im just afraid of snapping the bolt.

It doesnt say on the link i put up in the earlier post but its very important to tighten the bolts to the right spec. I dont know off the top of my head but it can be found in the FSM. This is important

i know it's important but is it even possible to torque it down with a regular torque wrench? i used a regular torque wrench to torque the clutch plate down to 25ft/lb and it snapped the bolt. And yes, i know how to set a torque wrench. So again, do you use a inch/lb torque wrench to do it?

I dont know y every1 calls them rocker arms (stoppers) even GReddy, HKS, Tomei, etc. They're really not even rocker arms in the SR20DET..... I guess its easier than calling them cam follower or finger follower stoppers :P

an inch/lb torque wrench for shizzle! and make sure you use a GOOD torque wrench.

i revved up my old sr20det about 3 times missing a gear (all the way up to 9k --- no rev limiter). nothing ever flew off and i never had any problems. no ras's were installed.

Huh? What are you talking about? The FSM even calls them rocker arms.

They are probably more oriented for racing like on a track where shifts may be at high RPM's and the RPM's are constantly higher than normal. Its not shocking that out of only 3 over rev situations nothing has happened.

[QUOTE=SpeedRacer1]Huh? What are you talking about? The FSM even calls them rocker arms.

I know....thats the funny part.....They're not......in that particular setup they're called cam followers not rocker arms. Rocker arms are pivoted at the center....that pivot gives u the rocker arm ratio which can be used to determine or even alter valve lift (if u change the ratio) in conjuction with the lobe lift of the cam......the cam followers just sit on top of the lash adjuster and the top of the retainer.......There is no pivot......at least not in the SR

thats what i'm talking about.....not that its a big deal

They are still referred to as rockers. Just because they dont rotate around a center doesnt mean they are no longer rockers.

yes it does......they may be "referred to" as rockers.....doesnt make them rockers....look up rocker arm in the dictionary them.....it'll prolly say something about a pivot....so without that its not....

if you want to go into detail, then they are all considered cam followers according to my mechanisms and dynamics of machinery book. yea im a mechanical engineer undergrad.

According to my engine rebuilding book they are all called rockers regardless of pushrods, OHV, OHC, etc.
