Hey, i'm lookin at doin my timing belt soon and was thinkin bout doin the cam gears as well, but know s**t all bout them. Just wonderin is there any advantage to havin them on or not, and what the difference is between the intake and exhaust one, since most companys have different part numbers for them. I've found some on ebay but dunno wether to go ahead and buy em or not, manly coz of reasons above

Dude............do a search, heaps of help here.

The value of adjustable cam pulleys/gears and what you get out of them depends on your supporting mods.

I'd also say that you won't need one for the inlet side unless you have removed your variable valve timing.

My advice - don't bother unless you have/intend to get supporting mods. Buy a reputable brand, avoid eBay.

Go to group buys or search on 'Slide' on SAU, you won't get a better deal from either option.

Have a look in the group buy mate you can get one for $90 delivered. This is what I did when I got my belt changed, only gained 5kw but for $90 thats not to bad. You only need one for the exhaust side as the intake uses NVCS. Have a look at the link below for more info on NVCS.

cheers

What kinda mods are we talkin here?? I've still got the car pretty stock, however lookin at throwin money at her later in the year. :yes:

Since you got an r33, you will only need exhaust side of it..

Supporting mods?? hmm i dont know what the other guy was talking about..

hmm to make most use of it after installation of the cam gear and tuning the gear itself is an aftermarket ecu.

With all the other usual mods.. Full exhaust, fmic, pod ..

I have seen gains from 5-10kw.. cheap power!!

Supporting mods?? hmm i dont know what the other guy was talking about..

What I mean is if you just buy a cam gear and slap it on, you might see 5kw.

If you have say a power fc and you install a cam gear you might see 10kw.

If you have a fmic, a bigger turbo, a power fc, zorst etc etc then you might see 15kw.

A cam pulley moves the cam timing, then it all depends on how much better your motor can breath, how much air can be forced into it, to make use of the move in timing.

Re-read the post............

I got adjustable cam gear put on my r33 and my tuner told me that he didn't tune it because there is will no power difference. My current mods are full xhaust, cooler, pump, safc, pod with heat shield and hks evc. does that sound right?

Quote Hot4's tech handbook:

'Where the turbo engine will gain most from cam gears is by retarding the exhaust cam shaft. Normally manafactures like to advance the cam more than optimum for peak power because their highly restictive exhaust manifolds and systems can force hot gases back into the cylinder, promoting detonation.

Start retarding the exhaust cam a couple degrees at a time and watch the power climb, particularly if the engine has a larger exhaust housing on the turbo or an extremely low-restriction exhaust system.'

I found this quite interesting, and has lead me to buy one soon for when I get slide max oversize turbo tuned properly.

I have a tomei cam pulley, used it at 5 degrees and got good power, I've still got it on, but had to reset it to 0 degrees for my poncams.

On a ECR33 Gtst with poncams, you usually don't need an adjustable cam gear.

I use the pon cams on my GTR with adjustable cam pulleys. i have a fully modified head ported and polished, 0.5mm oversize valves the works, and with my gears set at 0 deg the car hits full boost at 4900 rpm, with tweaking of the gears and fiddling with the pfc, inj and ign timing the car would hit the full boost at 4600 rpm. so they are worth the hassle if you want to gain smth extra, these things are realy the bang for the buck,.

    • Yeah, the latter. No diff should have a centre replaced without checking clearances because its unlikely to be the same as whatever came out. Not that that stops most people just checking a new centre in
    • Major thread necro but how bad of a job is it to DIY? Looking at it online it looks like if you reuse your ring and pinion as long as those are in good condition it should be fine to just pull the axles/front cover and replace the diff that way? Or should I be replacing everything and doing preload measurements/gear mesh testing like the factory service manual mentions for the rear diff?
    • in my list I had the R33 GTR as the best Skyline. Infact I had all GTR's (33>34=32), the NSX, the GTO, the 300ZX, the 180SX, the S15 better than the FD RX7. I had the MR2 and the A80 as 'just' better. I also think the DC5R Integra looks better but this is an 01 onwards car. I also think the FC>FD. It's almost like aesthetics are individual! The elements @GTSBoy likes about the FD and dislikes about the 180 are inverse in my eyes. I hate the rear end of the FD and it's weird tail lights that are bulbous and remind me of early hyundai excels. They are not striking, nor iconic, nor retro cool. The GTO has supercar proportions. I maintain these look much better in person (like the NSX) especially with nice wheels and suspension which is mandatory for all cars pretty much. Some (or all) of these you have to see in person to appreciate. You can't write a car off until you see one in the flesh IMO. Like most people we probably just like/dislike cars which represent certain eras of design or design styles in general. I also think the 60's Jag E type looks HORRIBLE, literally disgusting, and the 2000GT is nothing to write home about. FWIW I don't think the Dodge Viper Gen1's have aged very well either. You can probably see where I rate bubbly coupes like the FD. I know we're straying now but the C4 and C5 absolutely murder the Viper in the looks department as time goes on, for my eyes. Wouldn't surprise me if people who love the FD, also love the MX5, Dodge Viper, Jag E Type, etc etc.
    • I used to hate R31s, and any of the other Nissans that led up to it, and any of the Toyotas with similar styling, because of the boxiness. They were, and remain, childish, simplistic, and generally awful. I appreciate R31s a lot more now, but only the JDM 2 door. The ADM 4 door (and any other 4 door, even if they are unique compared to our local one) can eat a bowl of dicks. The Aussie R31 is also forever tarnished by their association with stereotypical bong clutching Aussie R31 owners of the 90s and early 2000s. I think the Nissans of the 70s (other than 120Y/180B/200B) are far superior looking to the 80s cars. The 240K era Skylines are boss. The same is broadly true of Toyotas. Hondas don't ever register in my thinking, from any era. Mitsus are all horrid shitboxen in any era, and so also don't register. Subarus are always awful, ditto. Daihatsus and Suzukis also don't generally register. They are all invisible. I think the SW20 MR2 looks fiddly. The 3000GT/GTO is like that but way worse. Too many silly plastic barnacles and fiddly gimmicks ruined what could have been a really nice base shape. Kinda-sorta looks like a big heavy ST165 Celica coupe (and I'm not sure if that's a good thing or a bad thing). I think the 180SX is dreadfully bland. It's not bad looking. But it has no excitement to it at all. It's just a liftback coupe thing with no interest in its lines, and bad graphical elements (ie wide expanses of taillight plastic on the rear garnish). The S13 Silvia is a little better - getting closer to R32 shapes. But still....bland. S14? Nope. Don't love it. S15...a little better. Probably a lot better, actually. Benefits from not being like a shrunk in the wash R34 (where the S13 was a shrunk in the wash R32 and the S14 looked like a Pulsar or something else from the stable on Nissan mid 90s horrors). The Z32 was hot as f**k when it came out but hasn't aged as well as the A80. Keep in mind that I think the R33 is the most disgusting looking thing - and out of all the previous cars mentioned is objectively closest to my precious R32. It's just....real bad, almost everywhere you look. And that is down to the majority of what was designed in the 90s being shit. All Nissans from that era look like shit. Most other brands ditto. In that context, the FD absolutely stands out as being by far the best looking car, for reasons already discussed. Going behind the aesthetics, the suspension alone makes it better than almost any other car.  
    • If they just called it the "Mazda Tiffany", it would have been spot on.
