Has anyone done before/after dyno with this exhaust cam gear yet?

Is an aftermarket ECU 'required' for these or is it only an 'advantage' ?

I'm looking for little things to get me up over 210rwkw on the Std ECU/Turbo and this looks like the next step.

Whats the typical cost to have these installed + tuned at a dyno shop ?

Edit: I was also liking the rice factor of the HKS Purple+Blue :P

Hi Guys, I bought a set of Jun adjustable cam gears on the forum a few weeks ago. They appear to be standard Nissan GTR pulleys with the centre machined out and replaced with a steel adjuster. If they are standard Nissan teeth they will obviously last as long as they would unmodified, provided the centre line of the adjuster is lined up properly during the machining process. They have 5 adjuster bolts which should provide more than sufficient retention.

UniqueAutosports sell modified standard pulleys for $185 each for the standard weight and $195 for the lightweight ones. So, as long as they have the same accuracy of centring there should be no problems with theirs either.

If you are not looking for looks (the HKS ones do look trick) or extreme lightweight, these are viable options.

Hope that helps.

I wouldn't bother loosing the VVT until over 250rwKW, and use the cam gears in conjunction with better cams.

Steve, Thanks for the link, what would the postage be? I have worked it out before, and the group buy idea is better as only one postage cost is needed.

The following table indicates the shipping costs to Zone 2, which includes Australia, New Zealand, USA, Canada and any country in Europe. For other countries, please contact [email protected]

Base rate (up to 1 kg) ¥3990

For each 500g more than 1 kg ¥525

Works out at about $55AUD for the first kg (ouch), but $14.50 for every kg there after, which is a bit better.

when were you thinking of getting these? Soonish I hope. I'm after 1 (for now - maybe 2 later), and wouldn't mind jumping on the group buy bandwagon

Cheers

Steve

Steve,

Can you find out the weight of the cam gears, plus are there any additional taxes that need to be pay for goods coming into Australia?

I can buy them whenever, just trying to find somewhere which is cheaper than I can get them here.

Not too sure about taxes, have you had a chat to customs. From most of the feedback I have read, it seems that if it is under $1000AUD they dont seem to worry a heap - never know for sure though. I did get my turbo through, but the guy at the other end put it down as about $380AUD - they opened it for inspection, but didnt hit me any duty.

I will drop them a line, and ask about quantity for group discount and unit weight.

Steve

so on a car with a big turbo (like a HKS 3040) and the usual other mods like fuel pump, injectors, engine management (I have HKS FCONV, VPC and PFC-FCON), exhaust, intercooler. Would it be worth removing the VVT and getting a cam gear for both inlet and exhaust? It's an RB25DET, and what sort of cams should i go for? 256 Duration and 8.8mm lift? or bigger, to something like 264 duration and 9mm lift? What would the difference be between the two cams?

I'm liking the sound of the Toda gears myself! The top end power is pretty good so i'm more after some street usable mid-range at this stage. I've also read on the other CAM thread that you might be able to get the inlet cam slotted to allow adjustment and still keep the VVT.... is this true or not worth it?

Thanks

Andrew

GiJOR33,

With a setup like that, then yes I'd do both cam gears. Sounds like a similar setup to what I'm going for.

Cam's I'd go for the 264's, but the 256's are also very good.

Yes, it is possible to slot the existing gear, but the VVT doesn't have sufficient impact to make it worthwhile doing at big horsepower.

See'ya:burnout:

A guy at work machined out the centres of my steel gears and replaced them with adjustable alloy centres (which he made as well). They allow +/- 4 degrees adjustment and only cost me $17 for the materials and a slab for the labour.

Guys go to a machining company with a design and all your standard gears in bulk and it will cost you **** all to get them modify.

Why buy wanky brand name gear? It doesn't make your car go any faster and it costs a fortune.

Pawley, I think the UAS ones are made exactly the same way as Rowdyr32's are. That would mean they have like a $150 markup on them. Which I guess isn't over the top, but if you look around enough you can probably get it done cheaper (let's all ask Rowdyr32's mate if he wants to do some more for us ;))

    • This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.
    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
