I'm just wondering if anyone in the Perth area (I'm in Vic Park) has a crank pulley installation tool that I could borrow tomorrow? I will come and pick it up / return it, put a deposit down, provide beer etc :P

Or alternatively, know where I could buy one at a reasonable price to suit Nissan engines, either today, or tomorrow?

I have a really tight Ross balancer and I'm going to need a proper tool to get it on :/

Cheers!

You dont really need an install tool to fit the balancer on an RB. Its ideal yes. But not a massive requirement.

You can just use the bolt to press it on as it has a large thread. But it can't be too tight a fit.

The reason they have have those install tools is for engines where the crank pulley bolt is only a 10 or 12mm bolt and will not be able to press the balancer on.

When i was looking at doing this, i looked at buying the tool to do it. They were all a generic tool with threads, adapters etc to fit a lot of engines. However none came with the M16/18? shank to suit the RB25 crank.

In the end, i just pressed it on with the crank pulley, it was actually a walk in the park. Pressed on very nice and easily. Put anti seize on the crank and wound the bolt in then torqued it. Easy.

The interference fit was very close to ROSS' specifications though.

I'm not sure how out yours is? You need a telescoping gauge and micrometer to creaturely measure the crank and the ID of the balancer.

EDIT - If its too tight you can't fit it period, this was done by a friend of mine with his ROSS balancer onto his engine, he didn't have a care in the world for specifications or the interference fit. Needless to say, when it was time to get the balancer off, it was almost impossible too and the crank had been damaged from such a tight interference fit.

Cheer's Kitto, I will give the standard bolt a go. At first I didn't think it would fit on at all, although I just measured with digital callipers. I sent it back to Ross and he checked it with a proper inside mic and the measurements were apparently all good and within spec, so I will give it another crack tomorrow with the standard bolt.

It is a pretty chunky bolt, should be OK I think.

The balancer should just sit on the tip of the crank before it stops. Then you start winding the bold in.

Make sure you put never seize on the crank.

Thanks Kitto, you were right, it went on pretty easy.

Not happy with Ross, I just got the balancer back from them and they have dropped it, putting a huge dent in it (picture attached). The box they sent it back in was fine so it was obvious they dropped it before sending it back. :rant: I put it on anyway, hopefully it will be alright.

Far out, thats bad! Id be looking at them getting it fixed, especially for what they cost.

Yes I should complain given the cost, but to be honest I'm sick of dealing with them and waiting to actually install it, so I'm just going to leave it. It shouldn't have any effect on it balance or function, or at least I hope!

Dude if your 100% sure that the damage was NOT there when you sent it dont ask ROSS.... DEMAND a brand new one... Its called a HARMONIC BALANCER for a reason... Not a banged up lump of steel and rubber to drive belts!!! The fact they sent it back like that is INEXCUSEABLE imo..

PS: Make sure you torque the bolt correctly? Not the old "Impact/Rattle Gun" She'll be right method....Its the Number 1 cause of oil pump failures on RB's......Crappy chinese (were many branded items now come from), old clapped out balancers are up there aswell.

    • GCG is a good company, they're a major distributor for Garrett in Japan as well.
    • Nah, OEM washer bottle and brake fluid reservoirs are fine I don't know what it is with the plastic that Mazda used, some plastics, like the washer bottle and brake fluid res are fine, and still look new after 20 years use, where as the coolant expansion tank, and PS reservoir, that I replaced with new OEM items when I first got the car, turned yellow and started getting brittle a few years later If the dirty yellow stained plastics didn't trigger me there wouldn't be an issue, but they did, much like the battery bracket....... Meh As for going back to work full time to support car stuff, nope, why, because I own a Mazda NC MX5, not a Nissan R series Skyline 🤣
    • I've never heard of CJ-motor, so can't advise you on them. I'd just go straight to GCG for a GCG highflow though. Seems no point to use a middleman. I'm somewhat surprised that the price on the CJ site is lower than the GCG retail price. Even though CJ would get a discount of some sort, you would hardly expect them to give up so much margin. Maybe the price is out of date? Having said that "I'd go to GCG"...when I did my highflow, I went to Hypergear. I did this https://hypergearturbos.com/product/rb25dethighflow/#tab-dyno-results with the R34 OP6 450HP profile. With the BB centre (extra $400) and intially with the standard boost actuator, but I eventually got him to send me the high pressure one when I got to the point of being able to actually use it. Ends up costing the same sort of money as the GCG highflow, but this is, of course, the turbo that I KNOW has a shorter length core and so moves the comp cover rearwards. The GCG apparently doesn't do that. My mechanic also swears by the GCG highflow, given that we have another turbo rebuilder who does something essentialy the same as theirs, using Garrett wheels. He says it stands up at really low revs and makes good power. I haven't pushed my HG highflow past ~240-250rwkW yet (should have a little more in it, but unclear how much) and it does have a fairly gentle boost ramp. OK, it's much better now that I have gotten my boost controller tuned up on it.  A lot of my earlier unhappiness was because I couldn't keep the wastegate flap as closed as it needed to be (including some mechanical issues). I'd still prefer it to boost up nearly as quickly as the stocker, and it certainly a bit slower than that. So maybe the GCG one is worth the first look (for you).
    • Ok thanks 🙂 I will higly consider this. Any "known" company for a good reviews and experience to send that off? Is that CJ-motor good one? Or go straight to GCG site? I need to use VPN to even find some of those "shops" let alone access them 🙂 
    • You can literally put in as much WMI as it takes to quench the combustion totally (and then back it off a little, obviously), and it will keep making more and more power. The power comes from the cooling effect of the water (and the meth) and the extra fuel (the meth, which also has massive octane). It is effectively exactly like running E85. One might be slightly better than the other, but they are damn close. But with either you can lean on the boost or the timing (or both) waaaay more than with just petrol and the results are similar. Here's the first thing I googled for an anecdotal bit of evidence. Can't access the attachment without being a gold member, but it is there for the getting if able to, or searched up elsewise perhaps. https://www.hpacademy.com/forum/general-tuning-discussion/show/wmi-vs-e85/
