aftermarket cambelt - GT-R Register - Official Nissan Skyline and GTR Owners Club forum

When i get my car i'm planning to change the cambelt along with service. Now i've noticed that a lot of guys use aftermarket cambelts, such as tomie. Are the OEM cambelts not very reliable, or are aftermarket belts just so much better? there seems to be a large difference in price and i just want to know if the extra price is justified and also to gauge some opinion from people.

Got a Nismo one on mine from Middlehurst, far better quality than the standard one and after 3000 miles, has not streached at all.

Im waiting to collect my car too... I bought a Tomei Kevlar item to be put on.

Its only £100 so thought it worth it for the peace of mind.

Personally, I can't see that a STD cambelt would stretch enough for it to be a problem. IMHO only fit an uprated one if you run steep cams @ very high revs..

That was my initial thought as well, TBH I'm still undecided as to which to go for. Where is the cheapest place to get an aftermarket belt, if there isn't as much difference in price as i originally thought then i may just get an afetrmarket one.

I'd go to nissan, dunno how much though, £30 maybe.

NISFAN · 16th July 2005, 01:43 PM

Buy one with Kevlar in it ........it's good for my companies share price

Pikey · 28th July 2005, 12:47 PM

£40 for a standard one, £100 for a GReddy one. I got the GReddy one, but on reflection I dont really know why

lol

What bloody cambelt would stretch after 3k of road use and how would you have noticed

Pulse D · 28th July 2005, 09:03 PM

I bought a Greddy Kevlar belt . . .

Also changed the pulleys to Greddy adjustable one's & fitted new tensioners for good measure! It all looked sooo blue and pretty, so i bought a clear Greddy cam belt cover so my girlfriend could see what i'd spent my money on!

P.S My car has done 50,000 miles.

An OE Nissan belt is fine..... I'd only fit an aftermarket belt if the engine was fitted with lairy cams and / or had a higher rev limit.
Also, the tensioner and guide roller should be changed at the same time as the belt

I got a Greddy one, was only about £10 more than a Nissan one, so thought it was silly not to! (Genuine Nissan cambelts are just over £40 if I remember right).

My point which I did not think need clarifying was:

That the cam belt was fitted with a new tensioner and to the correct tension accoring to my R34 GTR workshop manual. The car was used for about 3000 road miles including 2 track days. I wanted to replace my cams to stage 1's after all this and so decided to remove the belt in anticipation of the new cams turning up . To see how the belt had lasted, I check the tension again BEFORE removing the belt, and it was exctly as I had fitted it a few months before. I guess it could be argued that had the tension changed in the interim, it could also be down to wear in the belt tensioner?

Just my opinion based on my car.

From what I can tell the belt is under most stress at idle and cranking speeds (Im guessing less inertia on the cams)

I say this cos allmost evey engine I have worked on with a failed belt happened as ppl where just starting the car or just setting off from a junction, Only seen one belt fail at high revs and it took 10 of the 16 valves and the head with it.

Right now I use a good quality Powergrip belt as I change each year anyhow
If I was running an expensive modded engine tho, I would buy the best belt I could find
