jakeoster Posted December 17, 2010 Share Posted December 17, 2010 (edited) Well the other day I was working on a few things on the Z and I was visually reminded of how damaged my harmonic dampner is. Here's an older picture of it... There are considerable chunks missing out of it. I was looking around and the options seem to be either a Ross or an ATI. I was leaning more towards the Ross as it's more available. Now they run about $500, I was wondering if this issue is in dire need of fixing or not. It must be causing some kind of vibrations but does it take first priority over say a turbo that leaks quite a bit of oil into the intake side of the engine? Thanks for the guidance.

josh817 Posted December 17, 2010 Share Posted December 17, 2010 Of course it's never good like that but I don't see a problem with running it as long as you don't spin the motor up a lot... You might also want to try BHJ Dampers. They sell L-series dampers with trigger wheel setup, sensor and sensor bracket, for $500. The damper by itself is like $370 or something. Maybe RB motors will be around that range. Quote Link to comment Share on other sites More sharing options...
RB26powered74zcar Posted December 17, 2010 Share Posted December 17, 2010 Yea, that damper is pretty jacked. I would at minimum try and locate a decent used oem piece before putting any serious RPM to that motor. Watch all the classifieds from the various RB website forums, you should be able to pick one up, if moneys tight for you right now...

getoffmyinternet Posted December 17, 2010 Share Posted December 17, 2010 I'd sell you mine for cheap but I tried to lathe off the a/c pulley. It didn't work out. You might want to just break off that piece that's already cracked most of the way through before it goes flying off into something important.

getoffmyinternet Posted December 18, 2010 Share Posted December 18, 2010 I wonder if you could get it rebalanced if that is the only issue and cause for upgrading. Quote Link to comment Share on other sites More sharing options...

Maybe RB motors will be around that range. I dunno about that price quote there. All the L series harmonic dampers I've looked at there START at around $457, and another $140 and change for a trigger wheel. That's not even counting sensors or brackets (which I don't see there).

No dice anyway, they dont carry them for the RB. I gave it a looksee. Quote Link to comment Share on other sites More sharing options...
kiwi303 Posted December 21, 2010 Share Posted December 21, 2010 bloody expensive things... First page up on google was http://www.endevourengineering.co.nz/rb-26r34-ross-harmonic-balancer-metal-jacket-series.-xidp221256.html and they want 780NZD for the Ross one in NZ nearly 600USD, even with shipping and markup I wouldn't think you'd get them stateside for much change from $500. Find someone pulling a blown RB apart and snag an OEM in good condition would be my advice, it's obviously holding up alright even while buggered, so your engine can't be stressing it too much. I've a RD28 and a couple of RB20's here but shipping to the US would be a killer. Quote Link to comment Share on other sites More sharing options...
ZT-R Posted December 21, 2010 Share Posted December 21, 2010 i got my ATI from summit about 2-3 weeks ago for like 495. Quote Link to comment Share on other sites More sharing options...
dizzle Posted December 21, 2010 Share Posted December 21, 2010 I have had 2 RB's now and both pulleys looked like that. I wish there was a cheaper alternative, but with the dampened pulley they are never cheap. Mine isn't quite that bad though:) Quote Link to comment Share on other sites More sharing options...
jakeoster Posted December 21, 2010 Author Share Posted December 21, 2010 Now I'm just trying to decide which one to get. It's between the Ross Nexus and the Ross Metal Jacket. I think I might be leaning towards the Nexus though because it's not as expensive as the metal jacket. Nexus: http://rawbrokerage.com/Ross-Tuffbond-Nexus-Harmonic-Balancer-RB25DET-306101.htm Metal jacket: http://rawbrokerage.com/Ross-Metal-Jacket-RB25DET-Harmonic-Balancer-306201.htm As for a used oem, I've learned several times not to cut corners on an RB. It always seems to come back and nip you in the butt. I figure it would be wise to spend some money on a rotating mass like this Quote Link to comment Share on other sites More sharing options...

260zShooter Posted January 6, 2011 Share Posted January 6, 2011 Wow, those pulley's are almost half the price I paid for my RB. They better make it go that much faster. I'd just find a good used one. Quote Link to comment Share on other sites More sharing options...

I'd just find a good used one. It's a preventative part, not a go fast bit. My last attempt at buying a used oem part was a disaster and I was bearly able to get my money back. Now I just figure that most of the time if I buy used oem and it fails and I have to buy another then I might as well have bought a quality part in the first place.

Roostmonkey Posted January 6, 2011 Share Posted January 6, 2011 I just lucked into an ATI Super damper with approx 10k on it for $ 350.00. Also, the shop had a brand new, still half wrapped in plastic, never installed Tomei RB28. I almost soiled myself when I saw it on the stand. The guy was getting nervous because of all the finger prints I was putting on it. I was told for $ 28k I could have one too. It was glorious.

ZT-R Posted January 7, 2011 Share Posted January 7, 2011 for 28k it better vacuum your house and @#$%% your @#@()!* ya know Quote Link to comment Share on other sites More sharing options...
jakeoster Posted January 11, 2011 Author Share Posted January 11, 2011 Well it seems as though things have changed. I got a smoking deal on a brand new oem one. Only $100 shipped and it is brand new oem. Im happy, saved me 250 and some-odd dollars over the nexus damper from ross which is basically a stronger stock style one. I have also figured out a good solution for my turbo. Should have the Z running optimal in the near future. Quote Link to comment Share on other sites More sharing options...
