I like simon have spoken to john who has taken on Ross performance parts and his approach and knoledge is a credit to him and the product will only benefit from there involvement, I have used Ross balancers on my race engines in excess of 500 rwkw and 10000 rpm with not one failure of an oil pump or loss of a belt.. I have witnessed in the past many Ross balancers being fitted with incorrect offsets (power steer to crank pulley) this may have been due to incorrect supply or in accurate information regarding pump etc at the time of purchase, and many of these crank bolts have never been correctly tensioned, it is the repsonsabilty of the installer to ensure radial and face run out is correct before running the engine. In regards to oil pump failures if you use a n1 pump without steel gears then don't blame the balancer for your poor judgement. If you have an issue with a Ross product do your self a favour and pick up the phone and call john

When you say not tensioning properly, what do you mean and is this mainly with the 26's and 30's?

I just put mine on last week again, I use a touch of loctite on shaft, normal amount on bolt and pull it as tight as I can with a 700mm breaker bar, with car in 5th gear. The 26's are meant to be 460 odd NM? How the eff can you do that without 3 meters of pipe?

Mines a 25.

I used to use a breaker bar that was intended for flipping over the little wheels on a moveable 2WD dyno dynamics dyno ;) Its about 1.5 metres long and we used to swing off it to tighten up the crank bolt. She was never coming lose. Pain in the ass if you dont go back to the same shop to have it undone though

I now use my breaker bar with a jack handle on the end of it and still swing off it. I hope like mad that its tight enough and we dont have any issues ;)

I have never spat a power steering belt either. Might help though that its in an S14 and uses an S14 power steering pump

I just got the replacement dampener back today in the mail.

So all good on the company's part.

In regards to doing up the big bolt, on the RB26, putting it in gear isn't enough unless the car won't move when you put a 2 metre long pole on the end of your breaker bar!

My way was to drill a hole in line with the flywheel teeth in the bellhousing to fit a big flat blade screw driver in there to lock the flywheel.

Had a mate do up the bolt bit by bit with an extension pole while I was underneath holding the screwdriver.

Worked very well.

Otherwise I use a flywheel lock made by Eric when the gbox is off the engine.

Gtr has a bigger bolt. Id guarantee stripping bolt or snapping crank where collar is grub screwed if you did it that tight on a 25.

Cant you have hand brake on with someone on foot brake? and in 5th gear?

RB20/25/30's crank bolt is torqued to 142 - 152Nm. Most torque wrenches will do that, so there is no excuse for not torquing the crank bolt on those engines.

RB26, different story, 446 - 466Nm to torque that sucker. Only proper way to do it would be to have it in the car (Engine stand will move far too much applying that torque), sump off, nice stopper between the crank wall and the crank and use a 1" torque wrench capable of that torque. Might have to pay someone like a truck tyre shop to borrow a wrench that big for a day.

Someone else on another forum having the same problem, only he worked out how to fix it... power steering pulley was on the piss!

Worth checking.

mmm.. glad he fixed it. but in my case I am 110% sure this was not the issue. Went to great lengths to ensure it was perfectly lined up and straight. Even bought a laser alignment tool just to be certain.

So mine is spitting belts with this setup. Looks like the belt is trying to run over the front of the balancer. Will double check pulley alignment.

How does one go about moving the power steering pump back towards the rear of the engine??

Also looks like I will need to keep an eye on the longevity of the balancer too?? Few people reporting failures after 15,000kms.

  • 3 years later...

Just finished installing my race series balancer and trigger kit. 

After Initial fitment I ran a straight edge from balancer to power steering pulley and found the power steering pulley around 2mm out of square and alignment. 

This is using rb30 block, crank and power steering pump and bracket with an rb30 spec balancer. 

Some massaging of the pump mounts with a flappy disc and a die grinder had it lined up perfectly. 

Just word for thought I would always recommended double checking belt/pulley alignment to save future hassles. 

Just thought I would add Regarding belts, the power steering belt on the 32 GTR version has to be shorter as the stock 4PK950 is to long. Has to be changed to the same as aircon. Belts-

Alternator - 4PK880

Aircon - 4PK925

Power steering - 4PK925

Also re. Torque on 26 balancers. We use an old starter motor cut in half and welded locked, so you can use it as a flywheel locking device. No problem getting to 460nm.

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
