Id just go with what some of the guys who have built some fairly serious GTRs have reccomended i.e. Duncan said JJRs

I personally wouldnt put part on my car that i havnt had someone reccomend, and I have never heard of GKTECH, doesnt mean they are crap though

They look ok, auzzie company, and they use them on their own engine.

Could be worth looking into what material they are made from, it doesnt say on their site.

Good price though, might be worth a try...

Yeah..

I was heaps hesitant when buying mine, did the research, asked the right people and seen them on plenty of quality cars..

So picked up a set of JJR items, good bang for buck.

In a lot of cases it's not the cam gears its the mechanic!

look an adjustable cam gear is a very simple thing - thats why cheap copies work OK.

the important thing is that the centre locks the outer ring firmly in place. pretty easy even for the chinese factories to get right.

the other factor is....how accurate is their base setting (ie 0 degrees adjustment). When people say 4o retarted on exhaust and 2o advanced on inlet as a starting point, it assumes your new cam gears are 100% the same base angle as the factory gears. If they are only 1-2o out you get a totally different result (and it is literally mm only in difference between perfect base and way wrong.)

But the thing is, as long as you can spend a bit of time on the dyno, you can work out the best for your engine, cams and gears, regardless of whether their base setting is 100% right or not. so just buy the cheap stuff, start at a good base adjustmennt, and get you tuner to spend some time checking different settings.

And if you are wondering if adjustable cam gears are worth the trouble, even on a pretty stock motor - this is my most recent experience:

totally standard motor, standard cams, r32 n1 turbos, standard intake, standard boost (0.8 bar). adding adjustable cam gears made 31rwkw difference (over 10%).

I can understand both arguments, the "cheaper" ones should do the ob just as well in theory, but I think in the end you get what you pay for, I think I will settle for the JJR ones as its an important piece of hard wear and $100 - $150 is not much in the scheme of things and will have piece of mind they will not jam and the timing is on.

I think I might try the JJR cam gears, prefer to use something trusted by you guys. Just Jap has them for $250 for a set. is this around the money (locally)?

Also i'm taking my car in get to get a PowerFc installed along with a few other bits and pieces, would installing these add a lot to the bill?

Those actually look quite good, if you get some then let me know, cheap as well, but are they any better than others??? Ive got to make the decision soon as I am doing the 100k service and these at the same time.

Big jimmystyle, if you are installing these then you have to remove the cam gear cover, the timimg belt, cam gears which is not an easy feat as there are a few steps to get everything off, I dont know what the bill will be but it wont be cheap.

Installation is easy, I could knock it over in an hour or so. I did it not to long ago in my R32 GTST and it was pretty straight foward

Its just picking the cam gears that's the hard part :P

Last time I used HKS cam gears and they set me back around $300~ but I don't want to be spending that much again, $200 and under is what the aim is as they all basically do the same thing

$129 for a pair is a killer price but are they too cheap to be good?

    • Well, I can recommend the partial AV system translation CD I ordered from Car Audio Workshop in NZ. Whilst it didn't address the date issue, it has conveniently translated on-screen menu items into English, and now allows the GPS-received time to be offset in hours rather than minutes, so I can display Eastern Australian time accurately ( and bump it by another hour when daylight savings starts ).
    • Yuh, if it's 45°C outside, my car is driving in it.
    • I'd be curious to hear more. Otherwise, have you driven a modern x-trail? I wonder how it compares. Here in Australia they are/were popular for rentals and fleet vehicles. I have been in some and my impression was they are bad. But, this may have been very different in the 2000s at a good trim level. Twenty years is plenty of time to make the model worse. I do very much agree with the 2 silver cars in the garage approach. But, not driving because it's too hot would not leave a lot of time in the year for many Australians. I don't think you need to worry too much unless the car has actual issues with overheating. 
    • Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
    • Thanks for that, hadn’t used my brain enough to think about that.
