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.

    • Yeah well per the video it took 15s for the stock unit to start up....even if I give it a few seconds discount for starting that is at least 12 sec before you get a reverse camera if you are trying to leave a park.  The android unit is way faster, but 2016 for the stock unit is a long time ago in consumer electronics
    • Yea that’s why I said ima test them with multimeter and see the reads.
    • Only at idle. Isn’t a problem when rev it seems.
    • @Haggerty This seems silly to ask, but are you confident in your ability to tune the Haltech?  
    • Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
