id say JUN purely because it sounds better than HKS. :D

i imagine they are both the same duration/lift/etc?

I like the shcuzsched 'J' sound, its awesome....also they are a grey/black colour and would go with the resr of my Nismo gear. Found out that Nismo don't do cam gears :D

Yeah, they'd both be for the RB26 motor. Prices from Greenline.

Get the Tomei ones. Better than either of the other options.

Really?

I never really like the style of the Tomei ones, but I guess you dont seem them anyway ;)

So they are better than HKS and JUN?!

hks - ANODISED DURALUMIN CENTRE WITH NICKEL PLATED GEAR TEETH - duralium - synthetically made alloy - aluminium with 4.4% copper, 1.5% magnesium and 0.6% manganese. So its probably more flexible strong then strength strong.

tomei - are made from just duralium with no nickel. I am not to sure if this makes it stronger or not but the masses seem like them.

jun - I cannot find any info on these to be able to comment but my bet is duralium and nickel or steel.

sorry if im stealin thread, but what difference does just changing cam and cam gears do to a rb26 ?

I have a Nismo belt to do at the same time and a new radiator and hoses I will do as well. Just getting my car ready for things like internals (maybe) and turbos

JUN are stock Nissan gears modded and are ok but very heavy.

Very heavy? Surley if its a nissan gear with the centre machined out and an alloy centre it would be lighter than stock. (maybe not as light as hks etc)

But id rather pick a "non wearing item" for that kind of money.

We'll see in a few days anyway ;)

If you are thinking about new cams at any stage you can give the adustable pulleys a miss as the Poncams (To use but one example) have different centres to the stock items & you don't get such a gain from playing around with them.

Get a water pump too. You may as well do this at the same time as you will be up to your armpits in it all.

As for the whole steel/aluminium/duralium thing. It doesn't matter that much. What you have is essentially a rubber toothed belt that is running in the cam pulley. It doesn't wear the pulley worth a damn. The only way it can do so is if you are vain/stupid enough to leave the dust cover off it.

The advantage of an aluminium set of pulleys is that they are lighter & take some of the reciprocating mass off the engine & hence make the pulleys job that little bit easier.

The Tomei ones are good because they are from the appropriate grades of aluminium (ie duralium etc) & also have five locating bolts instead of three or four like many others. Lastly, the pretty blue colour matches my eyes & the red my handbag. ;)

Yes, I probably will get the Tomei Poncams in the future. So do the Poncams require specific cam gears that are different to stock items and the gears I am looking at now?

Water pump, I have been contemplating that but I have the radiator to do as well and I have no problem with temps as it is. I might just give that a miss.

      Rob's S Chassis track cars. Now with more s15 and less 180sx

      By robbo_rb180 · Posted

      So left off with high hopes of having a gearbox in pretty quickly........ Got the adapter plate that week and had to chase a few threads and work out how/where everything goes as no instructions. Got the adapter fitted, test fitted gearbox and found had to cut and shave a few things. Tunnel required some hits with a decent hammer to give some clearance on passenger side but it fits with no problems,  could fit a 8hp70 with a little more work. For a cross member I wasn't going to spend $1100 on so shiny machined piece. Went through a few designs and remembered I had a gktech s chassis to cd00# cross member. Fitted that and found its close enough with a few extra bits welded so have gone that way and still a work in progress.  After this got into modifying the intercooler with some bends and clamps. I was procrastinating on this as was not keen to cut up and weld it myself but happy with the outcome.  Onto the radiator shroud and oil cooler mount. This thing took way longer than I thought it would but having to add an extra oil cooler for the trans and wanting everything within the chassis rails its good enough for now. It mounts to the chassis and gives plenty of room for lines and pipes. All the coolers are rubber mounted and sealed the shroud on the top and sides, will use some tape to seal the bottom gap of about 10mm. 20250508_111500.mp4   Next job was to build the new diff and after a delay with a friend got built this week. I ended up putting it all together with supervision and was good to learn how to set one up correctly. I ended up going a 3.69 ratio, nismo 1.5 way gt pro with gtr Axel's. Stripped it all down, gave all the parts a good clean, pressed on new bearings and set backlash. Was good working in a clean assembly room with all the gear. Once got home wire wheeled the case and hit it with some rollbar/chassis black paint. Got a few more bits done but will leave them for the next update.

      That could be drilled, ground and welded. Would stop it progressing and leaking. But that block shouldn't be pushed very hard, as what you see there is a massive warning sign. But that fix also isn't going to happen properly with the engine in the car, and assembled. So you're looking at anew block if you're doing all that work anyway.

      Question about BoV on RB25DET NEO

      By GTSBoy · Posted

      It's not as simple as it is being made out to be. It s not hard, but there are things that have to be done. Am busy right now, but will try to essay later.

      By joshuaho96 · Posted

      Pinout is different to my knowledge, but you should confirm to be sure. Also you will need to adjust the VQ table in Nistune to suit. I would still recommend sticking with recirculating BOVs, I'm not sure if the R35 card MAF will fully resolve stalling caused by reversion/throttle lift.

      What issues are those? Previous owner said it wants to stall sometimes. We did test drive and it was nice and smooth so it will be sporadic or idk. And if i just change MAF(the sensor to R35 version) it should be better? And as i asked...is it like "plug n play" with oem MAF from R34?  This is a MAF from R35 right?
