[Adz2332]

Im going to buy some adjustable cam gears for me GTR and was wondering why i would pay $500 for tomei cam geasr when i could buy JJR cam gears for around $249 the pair???

Whats the differance between the two etc etc???

Yer name thats it just what i was thinking! lol

And is it worth using them on the 33 gtr with standered cam shafts?

i am using a pair i got off ebay (not the jjr ones) and found that when they heat up that it is very hard to adjust them as the inner alloy must expand slightly cause them to jam. Made it hard to adjust them when on the dyno.

OK this may not be an issue with JJR ones (ive never used them) BUT with various aftermarket cam gears i have used over the past year or so i have found MOST are not true to the timing marks.. ie zero is far from being actual zero... in once instance the gears were close to 10 degrees off.... This is a real pain especially if you have a recipe that works and pre set them.... this engine with the real bad gears lost 15rwkw str8 away up top and quite a bit more through the mid, we had to diagnose the problem on a dyno and re set them to get the most from the combo and the money saved from the cheap gears was less than the extra dyno time to find the new optimal gear settings.

Best bet is to buy them and expect the worst, and time the engine to make 100% sure your cam timing is where you want it... For me this now means i charge more to install no-name gears as i have to determine accuracy before it leaves the garage.

yes plz pm me... but by the sounds of it i should save the extra cash and by decent ones... that saying have you ever had trouble with brand name ones???

Is it worth getting them now, with the standered cams and computer?

I would spend cash on a ecu before anything else.

The cheaper ones I have seen tended to be made of hardened alloy and the teeth wear out fairly quickly.

Yer X2 now we know what are S**T quality whats the BEST

Just get the factory ones modified.

Cheaper again, and perfectly fine. Plenty of people have done it and then you get no issues with wear, no timing issues and KNOW they will be right.

The HKS early pulleys were not sufficiently hardened, teeth wear was obvious after as little as 5,000 k's. So simply going on brand name alone is not always a good idea. We use Jun, never had a problem, so I haven't bothered to change.
