what is better

 

This is going to have to be elaborated on.

 

I mean which one is better and reliable.

UR should be on the list too eh?

 

I've never had any problems out of HKS or Fidanza.

HKS takes my vote !

 

HKS cam gears are nice and I have never seen one slip yet. However, I would recommend a 5 bolts design if you want extra safety margin. Helix has a great design and the price is great compare to other brands.

Thanks,

Findanza. You have use the left over money for liqour/titt1ebar :P

 

hks all the way, never heard n e thing wrong with them.

 

IMO - AEM - hands down.

Look at the number of bolts. That takes out HKS w/ 3 - then look at size of bolts - that takes out Fidanza as their bolts are much smaller in size.

Also, not familiar w/ HKS but I beleive the fidanza's for the Evo are basically the same as the eclipse gears and as such you have to take that into account when bolting them up. The AEM are specifically for the Evo.

 

AEM gears are the ****

 

Ive seen several Aem Cam gears(5bolt) break and slip. Never seen an HKS break. I believe the design of the aluminum pieces and how they fit together is more of a factor than whether its a 3 bolt or 5 bolt design.

 

Fidanza

If ams runs them you know they have to be good.

 

on the AMS website it says they run UR cam gears, have they changed them?
