my evo is in desperante need for a new cambelt

was just wondering is the average old repco spec cambelt kit for around $400 just as good as the hks ones you see in performance car?

are the hks type brands just for wank factor?

also is $400 at repco a good price for the belt, idler bearings, tensioners etc?

It a wear item and while gates my warranty the belt for 250,000km I am sure they will not give you money for new pistons, valves, machine work etc when it does break.

I can just imagine, "Oh sorry to hear that it broke, here is a new belt".

I believe in changing them more often rather than buying "Performance" belts.

Agreed

Benefit of the JZ with a 2 piece pulley means it's a 15min job - I do it once a year now at the longest ($30 for a belt, why not

).

have heard and seen a few gates belts break after not so long so personally i would stay away. mark (whynot) had one break and destroy an engine and when asked about the warranty etc they didn't want to know about it.

a decent cambelt is made to stretch less so when there is a lot of load on the engine, the timing doesn't get retarded (have heard about 2-3deg) by the cambelt becoming longer. this is in a very extreme case mind you but it does make a difference.

just personally i wouldn't go for a belt that isn't OEM or decent aftermarket quality on an interference engine.

I personally like Toyopower belts from Partsmaster - Used both at high HP levels without issue so far.

I've never heard of any belt breaking before it's time that wasn't caused by the waterpump/tensioner/other part.
However I did notice when at Toyota that gates ones will fail sooner than OEM. I'm talking like 20-50k over

Yeah genuine Toyota belts are awesome! I ran my dads one on his 2JZ NA to 140km before I finally changed it (lazy streak) - It was also coated with oil from leaking cam seals.

Toyota definitely did well on this engine. Only changed my tensioner and water pump at 180k. Though I run gates belts primarily due to a change in pulleys

I have always used, and sold bosch timing belts

Gates belts are OEM spec, so if your belt is meant to be changed at 100k, then the Gates one is too.
In all my time of selling them, I've only seen one fail, and that was due to oil contamination...

How much oil does it take to start doing bad things with the belt? Soaked or the odd drip?

Sorta in between. A continual small drip will screw it eventually, a crank seal failure will kill it in weeks.

by **h8wrxs** » Wed Jan 19, 2011 10:38 pm

so is $400 about right for a cambelt kit from repco, i think it was a gates belt it some with?

or can anyone recommend somewhere/ sell me a kit cheaper?

The HKS etc belts aren't just for wank factor. They ARE actually stronger than OEM belts. Comes in handy when the engine is revving far beyond what the factory ever intended. Using an OEM cambelt on a 10,000rpm 4G63 (for example) is just asking for trouble. At those sort of revs there is so much stretch in the belt that you start getting inconsistent triggering and sync between the crank and cams when using a weaker belt.

If there is no reason for you to get one then you won't get any of the benefits of having one - much like most "performance mods".
