So yesterday, giving the car an once over before tomorrow night's event I noticed something rather alarming.

The Ross PS idler actually fouls the AC compressor belt.

You can see the scoring on the lower belt. I tried using the RB26 spacer included in the kit but it ends up only supporting 2/3s of the belt and the other 1/3 overhangs. Either approach is going to be good for tomorrow night so I ended up using a 4mm or so washer and packing out the bracket to move the idler forward. Seems clear everything now, however the idler bracket bolts are now really close to the PS belt itself. (Didn't take photos of this, finished up late night and just wanted to go to sleep).

I've contacted Ross Performance and hoping they are able to machine down the RB26 spacer, here's hoping they reply at all lol...

I'll take a photo of what I've done tonight when I'm back home.

It seems they didn't design this for RB25 motors with AC, or thoroughly test fitment on all combinations and permutations.

Then again their target market are heavies.

Added spacers to clear the AC belt and had do remove the spring washers on the bolt side to allow it to clear the PS belt.

Fun times, not. Piece of shit car, always spannering the lump of shit before events.

There's about 8mm of clearance to the fan blade, camera angle makes it look much closer.

Will trade for a F80 LCI M3 if anyone is keen?

So update, Ross said they would review it and they never got back to me.

After a couple of follow ups, nothing. Even tried messaging them on IG and nothing. Guess I'm not a big player (spend heaps) or have any social presence.

They're happy selling products that semi work (works great if you don't have A/C) and when you try to provide constructive feedback you're met with radio silence.

Guess it will just have to live with the spaced out bracket using washers - better than nothing, just annoyed I bought something that was supposed to be engineered to fit.. Oh wells, shit box Nissans.

It would seem to me that if there is sufficient meat on that idler, then machining a couple of mm off its diameter would help? Or, per my original suggestion, can you do something about the alignment of the mount to the front of the engine to lift it up vertically a little? Or a little of both?

Or, a smaller diameter idler to replace that one?

Both your solutions are valid, for now the spaced bracket works and when the car is due for any kind of belt change/timing, crank trigger kit (won't be using Ross after this experience), etc. I will look into replacing the idler OR skimming off parts of it.

Sigh... I hate modifying cars now.

I just had similar issue on my r34 gtr where the pulley bracket is hitting the ac compressor belt. Although I have the Ati damper on. 

Did you try to get in touch with Ross? They will start to reply then ghost you completely.

Even though I was super polite and understanding.

Guess I'm not some famous tiktok YouTuber, hence they don't give two shits.

How much is it pushing down on the PS belt? What if you slot the top hole in the mounting bracket so it can rotate toward the PS pump and raise the idler enough to get it off the AC belt.

In my experience with some mates drift cars, the belt gets flicked off on the sudden decrease in crank pulley speed on the limiter or downshift in a dog box. We came up with a good fix for the 2J using some Mazda timing belt idler that was just resting on the belt and stopped the belt coming off on some cars that were chronic for it.

Thanks for the advice. We are try to shave off some material from the bottom of the bracket to see if that works. I ideally wouldn’t want to slot the holes cause that would have the chance to move I think

Similar experience with Ross pulley. Can't recommend.

Useless lot aren't they?

Releasing stuff on the market that doesn't do what it's supposed to do without you stuffing about with it and spacing out the spacer lol.

FFS.

I think I will try out Frenchy’s power steering kit. Looks like a better solution.

I think throwing the hydraulic power steering system into the trash and converting to electric power steering, e.g. Astra PS pump would solve many issues.

I just put one on my car, nice bit of gear. I've had an astra pump on a car before and wasn't a huge fan, need a way of controlling the pump  speed so it doesn't drive like a '70s Valiant

      7 Speed Auto transmission fluid change (Skyline, Q50, Q60, Fuga, Q70, A62 Titan and probably heaps of others including Navara...)

      By Duncan · Posted

      I thought I'd do a write up on an auto transmission fluid change for a the nissan 7 speed Automatic. At some stage the genius engineers decided that the fluid in the trans was "for the life of the transmission", (which seems kind of self supporting to me) and removed the dip stick and fill tube (funnily enough there is still a casting for it). Anyway, for this job you do need 2 specialist tools in addition to regular hand tools, jack and good chassis stands. You need a way to pump fluid up to the transmission; I got one of these but there are plenty of other options: https://www.ebay.com.au/itm/364584087070 Don't trust the generic listing though, it does not come with the required adapter for the Nissan 7 Speed. You need one of these, can't do the job without it: https://navarapart.com.au/product/genuine-nissan-patrol-y62-d23-np300-navara-re7-dipstick-fill-connector1 You need a heap of compatible transmission oil. Could be Nissan, could be anything else rated for Nissan Matic S. You need at least 10 litres, I had 15 to give it a better flush... Also, you need some biiig oil catch trays, at least one of these, or bigger if possible (volume was fine, size was very marginal): https://autobarn.com.au/ab/Autobarn-Category/Tools-%26-Garage/Specialty-Tools/Oil-Service/Garage-Tough-Oil-Drain-Pan-Black-16L---GT1068/p/TO03191 Finally, a measuring jug is very useful if your pump does not have volumes marked on it, I got a 6l one: https://www.repco.com.au/oils-fluids/fluid-accessories/measuring-jugs/penrite-measuring-jug-6l-pmj006/p/A5322648 Oh, and gloves.....this stuff is horrible (not as bad as diff oil, but getting there) ....First, jack up your car.....

      So I mentioned the apprentice, @LachyK helped take the bonnet off. We just undid the nuts on the hinges and unclipped the gas struts, then pulled the bonnet back a little as the front was catching on the front bar.  I had a good look at everything today and have removed the rams, repaired/reset the hinges and bolted it back together like it never happened. I'll do a separate write up on the repair, and I also removed the poppers from the Fuga today too to save grief down the road.....as said above it is at least $5k to repair retail. I'm also happier about my ability to prepare a race car, and less happy about Nis-nault's engineering (I can hear @GTSBoy sAfrican Americaning) because the top hose of the radiator didn't slip off.......it snapped clean off. By practice I put the hose clamp hard up against the flare on a neck to make it least likely to ever move (thanks @Neil!). I guess that puts a little more pressure on the end of the pipe as it is further away from the rad, but still, that is pretty shit. I've put it back on for now as there was a fair bit of neck still there, but obviously there is no lip on the neck any more so I don't think I'll track it again until I have a new rad. Speaking of which....more research required. It looks like Koyo makes a standard size radiator in ally which I'll grab in the meantime, but I really want something thicker so might have to go custom in the medium term (ouch) Coolant still needs a refill and I have the pressure tester on it over night, but other than a wash down of the engine bay it seems alright. And @MBS206 noted something noisy on the front of the engine and I think I agree....time for a new accessory belt and tensioners I think.

      our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)
