Another thread over on the performance forums with additonal info. They accomodate the trigger kit nicely, i think prep and correct installation goes a long way to making them work correctly.

Use a ross balancer and trigger kit that I bought late 2016 on my built rb25 ~600hp, dyno work, rollracing, track night and street work so far. pulled the motor out to sort another issue and everthing is in great condition with no issues snout is fine, balancer is fine trigger kit is brilliant so in the short term it hasnt caused any issues like decives older balancer.. When talking to one of the techs over the phone he seemed to think incorrect install and not torquing the balancer bolt can cause some issues. Would not hesitate to buy another ross balancer.

Just got my car back today from MRC Mark said he replaced the 3 standard drive belts with smaller sized ones to fit the smaller underdriven pulleys correctly. Worth noting for anyone else looking at replacing their balancer as the original belts can be chucked back back on, but not ideal. Mine was the basic metal jacket version that is compatible with AC in stock location.

 

While the car was there I also got my injectors serviced so i got Mark to spin it up on the dyno to do a check over and a few power runs to ensure the balancer and fuel were doing what they were supposed to for peace of mind.

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.

So based on recent experiences people are happy all this hoo-ha has been resolved with Ross balancers?

I have myself in a pickle where I need a new R33 GTR power steering pump and when you can find them people want the same money as a Ross balancer that means I can go back to either of my old PS pumps with a vanilla Metal Jacket balancer. 

Silly question are they any heavier or lighter than std?

Ross has also updated their balancers in mid 2019 to have an integrated crank trigger and also a bit more robust (slightly higher HP rating) across the range.

Ross Performance Parts are excited to announce the release of our new **Nissan RB Metal Jacket Harmonic Damper with Integrated Crank Trigger Disc**

We decided it was time to rebuild our RB Metal Jacket from the ground up. Incorporating over 15 years of experience, countless racing engine hours and feedback from industry experts from around the globe, the result is a product that is not only cheaper, but better, than our old 'bolt on trigger' option.

The integrated trigger has a number of benefits. Not only does it seamlessly service crank triggering, it also allowed us to increase damping mass by a huge 20% in our Metal Jacket range while decreasing overall assembly weight. These changes resulted in an increase of the horsepower rating to an industry leading 800hp, while still maintaining all OEM pulley diameters and offsets for a true bolt on upgrade.

    • Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 馃檹 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 馃槈. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 馃槏 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car

    • All my Polish car culture insight comes from watching Nightride. So I half expect this to get 1UZ swapped eventually?! Are you going to drive it in winter? I'm always curious how ATTESA would hold up in the snow. There isn't that much opportunity to try it in Australia.
