i'm with rev210 i think your bolt would have broken first causing the cam to break, the same thing happen to a set of hks cam in WA. On the bolt i will never reuse std cam bolts again after seeing two break on removable of cams for the rebuild. Tomei upgrade studs are not very $$ and well worth the money.

Yep...they are. Only thing is, they are a butt pain if you want to fit mines cam baffles.

Sorry to dig up an old thread but I found this topic whilst searching and just after some more input on replacing the bearing cap bolts when swapping camshafts. Poncams will be going in my RB25DET pretty soon and I want to make sure its done right.

I found these on the nengun site and it appears they are only made for the RB26 (tomei website confirms):

Would they work on a 25 as well? Is it a worthwhile investment in your opinion? The cams will be installed by a professional but still I would like to know what people think.

Cheers :(

Installation....renewing of retaining bolts.(Bearing Suds.)....measuring up shims....making sure they fit well

into their seat or cradle are all important.

I needed 21 new shims because all mine were out of wack....or someone had removed after market ones before

and put back the original and not checked shims and clearances.Who knows?

I mean do you know the entire history of the car?

Did you change any shims or checked clearances.....

I asked this question before and got the answer...Poncams are a direct bolt on....nothing else needed.

What a load of Shit...

Anyway back to the topic........90% Installation and 10% Defective product,,..that is the way I would measure it.

      I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps

      Can you mount the ATTESA pump in other locations?

      According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car.

      It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.

      If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
