Hi Guys,

I want to put adjustable Cam Gears on my R34 GTT as I have Tomei Type B's Cams installed. The VCT (NVCS) is not been used. The Exhaust Side fits on no problems but the Intake side does not. The Intake side can be bolted up to the Cam Disc that sits in front of the Cam Gear but the hole on the Cam Gear that sits in the Cam is too big.

I did a 30 minute search on the forums and have found nothing, I have tried searching everywhere for an adjustable Cam Gear that fits on with no success. There has to be people who have installed Adjustable Cam Gears in their 34's.

Can anyone help me with this? Shed some light on any products or what type of setups they have.

i was under the impression that Rb25 guys didn't do cam gears that much as it doesn't make the difference it does like on the Rb26's?

and if they do, i think they only do one side (exhaust?) and leave the rest - why would you not want your VCT? would that not be more beneficial than cam gears? i think that may have something to do with neo people not changing them perhaps, and you not being able to find anything in search results

in all my years of GTT ownership, cam gears didn't once come up in discussions with my tuner or other people - but then again, i was running standard camshafts, maybes that's why

Hi Guys,

I really appreciate your input and as from checking out many tunes. I am just going to leave the stock cams gears in. I find the VCT pretty much useless, it's only on the Inlet side + you don't see GTR's with a system like this. And for good reason.

How did you conclude that the VCT is useless ( stupid Nissan wasting money?)

Have you done a dyno run with it switched on and then with it disabled and compared the charts?

Sorry dude but you will never beat the low/mid range of the VCT, it's simply impossible.

RB26's didn't come with VCT simply because it was not an option - not for good reason.

Think about why people are using RB25NEO heads on 26 bottom ends, HKS V-Cam, jaycar style VCT controllers setups etc etc

VCT is king. End of story. If it's not working for you then you have underlying issues causing these gains not to be realised.

Hey guys,

Thanks for posting the graphs up. The low to mid range is a big improvement with VCT. I did eventually find a set of cams that will keep the VCT. There from Greddy and cost a fortune but are well worth it :)

    • LOL, when one "money pit" is never enough Noice, and excellent work mate
    • I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed
    • I hear that would involve some nice country road drives into the hills for Mark...
    • I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.  
    • Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
