Hey guys I just got my car back from the dealership Saturday and they told me that my belts are cracked and very soon they will break. I was looking for some new ones and found the OEMs for $30 on ebay from a Infiniti dealer. But I was wondering since I'm going to get the belts changed I might as well look into some pulleys for a little more power. I found a few that come as a kit such as

Unorthodox Underdrive Pulley Kit(3 pc) w/belts - 03-07 Infiniti G35

Agency Power AP-Z33-130 Lightweight Crank Pulley Set Infiniti G35

Both of these are around $300 so here is my question are they worth it will they give me power? I am not planning on FI on my car check sig for future plans. Just want to get a little more power out of the engine that's all. I am about to order the Megan TPs are we speak, next pay will be the KCR (hks rep) then the Mrev with a spacer and a UpRev Tune and that's about it.

Just give me some advice on the pulleys and belts please should I or just replace the belts and that's it?

Thank you

 

The pulleys dont really add power but i heard you can go thru your rpm's alot easier. Id say with a light weight flywheel you would dilef be in for some fun!

 

The pulleys will make no difference at all,
if they are under drive, then you will have a nice faster alternator, and power steering pump.

 

Thanks guys did some research found out that is pretty much waist of money I'm going to go with just the belts thank you all

 

yah just do the preventative maintenance on the belts man! im just approaching 50k and the nissan tech finally recommended i change them. $100 for peace of mind aint bad at all. From what people have said, the unorthodox pulley isn't going to give you any noticeable power.

 

Change the belts yourself! It takes literally about 10 minutes! Don't waste your money at the dealership. I paid a guy to do mine for $30 and it was crazy to see how easy it was. I paid a dealership around $200 to change the belts on my Acura and looking back I got raped.

 

Oh I'm not gonna let the dealership do it bro idiots quoted me $275 for belt change lol. My dad use to be a mechanic. He will help me do it, I just wanted to see if it was worth putting the pulleys or not.

 

go to the dealer and have them advance your timing by 2 degrees

 

Why not just go to your local NAPA and get the belts there????? That way if they are the wrong size or something they will stand behind it?
