yeah I know it's been covered before and stuff but I'm a little confused...

Sydneykid says that they're the same here. Yet when people have installed GTR cams they have better response etc...

can someone explain please? I've been thinking about a cheap mod and cams seem like the most logical thing for me without having to increase the boost.

I've been thinking about getting the STR cams that UAS have ($380 a set) which seem like a damn good price to me.

Anyway yes please explain cam thing...

The question was.........

rb20 and rb26 cam gears same ??  

--------------------------------------------------------------------------------

anyone help me out here

My answer was

YES.

That means the CAM GEARS are the same, not that the CAMS are the same.

Or have I missed something? :confused:

yeah i think there is a misunderstanding here

the cams or camshafts are the long rods with lobes on them that sit in the head.

I think you are talking about cam pulleys or cam gears, they are the round cogs on the end of the camshaft.

Hope that sorts it out cereal killer.

greysky, read the thread i started a while back.

a basic answer is they physically fit in place without any problems, however adj cam gears and aftermarket management is needed to have the engine running properly.

i didnt have these and found my car wouldnt hold idle or run very well below 3000rpm

i think its definately possible... and a cheap upgrade but will tell you more once mine go in :)

thanks for clearing that up mate.

will a S-AFC (blue screen) be able to manage the idle lumpiness.

My car exhibited the same exact symptoms that BBenny's did. It simply would not idle. Since that little experiment I've discovered a couple problems that definately contributed to my problems. The cam swap forced me to basically troubleshoot my entire car and perform some routine maintenance that I had been neglecting. I found the AFM harness was loose and brittle, I re-grounded the igniter box, my 02 sensor was fried which was fouling my plugs pretty badly so they too were replaced.

The car runs much better now than it did before the cam swap attempt. I'm going to invest in a set of adjustable gears and give it another go in a couple weeks. I'm very interested in anyone elses progress with this swap.

haha no i didnt take it like that :D

no i went and spoke to several workshops and they didnt beleive the tight inlet would have caused such a prob, if it did it would have seized very quickly after driving.

so i think that ecu and adj cams should see the GTR cams working.

      V36 2008 Coupe Wiring Differences with Android Screen

      Right, here's a video of the basic operation at least.  This is what you can expect day to day when you turn the car on and it boots from standby.  The only thing from a media point of view I haven't gotten working is for it to autoplay plexamp when it turns on from standby (it works from cold boot) but that's more of a plexamp problem as it will autoplay other music players.  Also attached is my one stray cable.  It's part of the screen's wiring adapters but there's just nowhere for it to go in my car.  I've just now done a bit of research and found a matching port on a 2010-2014 head unit with BOSE.  Mine has no BOSE so that's that case pretty much closed I think.  Plugging in the Infiniti AC panel basically did nothing for me, so that's a dead end as well.  Next port of call is to mess with this CANBUS module and see what I can find from it.  I found this resource containing the DBC files for a 2010+ G37 : https://github.com/icecube45/Dash_InfinitiG37/blob/master/InfinitiG37.dbc I'll now have something to go from when I try to extract my CANBUS data so I can see if the HVAC Mode, Fan Speed, Temperature, etc. match and also the gear shifter position.  It's a pretty big assumption that it's just mismatched CAN signals but considering all the devices in the CAN network are talking to each other (AC can be fully adjusted just with no info on screen) it might be a safe one.  I will report back WhatsApp Video 2025-02-26 at 12.49.10.mp4

      Thanks for that Paul.  Do you think if I posted a picture you'd be able to remember where it went?

      By sausagepianist · Posted

      Sorry Duncan, I didn't get a notification for the replies.  Thanks for responding!  It's a full Android device, but does allow you to use CarPlay/AA as well.  This is the one I bought from NaviRS on AliExpress: https://www.aliexpress.com/item/1005006368602668.html?spm=a2g0o.order_list.order_list_main.111.59aa1802JDzQ0E - the 2K 8G-256G CAM variant but it seems to have gone up by £170 since I bought it!  My purchase was ￡307.14.   It's not the fastest thing in the world but performs perfectly adequately.  It stays on standby unless I disconnect the battery and let it power down, then it's just a fairly standard Android bootup time from cold.  The DSP Equaliser is very nice and made the standard stereo system sound pretty decent compared to the stock screen.  Perhaps I can take a video of it when I get a sec. It *allegedly* supports the reverse camera, but I'm yet to get that working.  It has options for reverse cam (a camera unit can be bought separately) or 360 cameras (also bought separately).  To be fair it doesn't seem to detect that the shifter was put into reverse but I'm working on a theory about this as well.  At the moment I'm going without which is a bit annoying considering the car is an absolute canal barge but so far I haven't caused any damage I'll grab a picture of the wire I'm missing later today when I can get outside.  My theory, by the by, is that not only is the head unit different, but the CANBUS network has different signals for the different years.  I think this because I have a spare AC panel from a newer Infiniti G37 (as opposed to my Nissan panel) which wouldn't control anything except the volume when I had it wired up with the stock system.  I'm going to throw it back in and see if the screen will respond to it.  I've just ordered an arduino CANBUS module so I can have a look at the signals going around the car and see if I can spot anything.  I'm thinking if I can work out what it's expecting vs what it's getting I might be able to translate and relay the signal back but so far just a theory anyway. I also found this on my travels, so far the only one that specifically matches my car: https://www.aliexpress.com/item/1005002822934280.html?spm=a2g0s.imconversation.0.0.33433e5fgttovi If you look at the picture of the before, it has the card reader slot, and the picture of the head unit is exactly the same as the one pictured in my original post.  I asked if they sell the cables separately but sadly they won't.  I didn't want to just buy this one because it's a super old Android version and only dual core - likely slow as hell.

      As above, you did refill the coolant and burp the system before running it again didn't you?

      To be fair - you see the same thing for every clutch. There's always someone making an installation error.
