Hks Or Jun Cam Gears? (scratch That I Ordered Tomei's)

[Topaz]

Should I get -

HKS cam gears for $315

or

JUN cam gears for $360

Dunno why but I am partial towards the JUN gears.....

(Shit!, I added a poll but it doesnt seem to have worked )

[mitchy_]

id say JUN purely because it sounds better than HKS.

i imagine they are both the same duration/lift/etc?

I like the shcuzsched 'J' sound, its awesome....also they are a grey/black colour and would go with the resr of my Nismo gear. Found out that Nismo don't do cam gears

Yeah, they'd both be for the RB26 motor. Prices from Greenline.

Jun apparently they have a different material used in the gears bettter than hks

For an extra $45, that sounds promising

HKS use Nickel and Duralumin, what do JUN use?

Get the Tomei ones. Better than either of the other options.

[Mike.]

The Jun ones have a steel tooth section with an alloy centre.

I just ordered a set of just gears and cams too.

Mike.

Out of curiosity what makes the Tomeis a superior item?

JUN are stock Nissan gears modded and are ok but very heavy.

Really?

I never really like the style of the Tomei ones, but I guess you dont seem them anyway

So they are better than HKS and JUN?!

[Tofu]

hks - ANODISED DURALUMIN CENTRE WITH NICKEL PLATED GEAR TEETH - duralium - synthetically made alloy - aluminium with 4.4% copper, 1.5% magnesium and 0.6% manganese. So its probably more flexible strong then strength strong.

tomei - are made from just duralium with no nickel. I am not to sure if this makes it stronger or not but the masses seem like them.

jun - I cannot find any info on these to be able to comment but my bet is duralium and nickel or steel.

sorry if im stealin thread, but what difference does just changing cam and cam gears do to a rb26 ?

I have a Nismo belt to do at the same time and a new radiator and hoses I will do as well. Just getting my car ready for things like internals (maybe) and turbos

Very heavy? Surley if its a nissan gear with the centre machined out and an alloy centre it would be lighter than stock. (maybe not as light as hks etc)

But id rather pick a "non wearing item" for that kind of money.

We'll see in a few days anyway

If you are thinking about new cams at any stage you can give the adustable pulleys a miss as the Poncams (To use but one example) have different centres to the stock items & you don't get such a gain from playing around with them.

Get a water pump too. You may as well do this at the same time as you will be up to your armpits in it all.

As for the whole steel/aluminium/duralium thing. It doesn't matter that much. What you have is essentially a rubber toothed belt that is running in the cam pulley. It doesn't wear the pulley worth a damn. The only way it can do so is if you are vain/stupid enough to leave the dust cover off it.

The advantage of an aluminium set of pulleys is that they are lighter & take some of the reciprocating mass off the engine & hence make the pulleys job that little bit easier.

The Tomei ones are good because they are from the appropriate grades of aluminium (ie duralium etc) & also have five locating bolts instead of three or four like many others. Lastly, the pretty blue colour matches my eyes & the red my handbag.

see now that is knowledge.

Yes, I probably will get the Tomei Poncams in the future. So do the Poncams require specific cam gears that are different to stock items and the gears I am looking at now?

Water pump, I have been contemplating that but I have the radiator to do as well and I have no problem with temps as it is. I might just give that a miss.

[djr81]

No they don't. But the lobe centres on the cam are different to the Nissan ones.

To change the timing belt you have to take the water pump out. Given how cheap they are it is one of those may as well do it jobs.

[play r 32]

yeah thats some good info, but my question can u make more power by just changing cams? or are they only good when coupled with other mods?

[Mike.]

Last set of HKS gears that were on my car were very obviously warn down in the centre of the teeth.
