Does someone have the belt size that I need to get to run the UDP? I'm assuming its the serpentine belt. I guess I need the mm size. I searched on the ORG but I haven't came up with a definite size.

 

i recently asked the same thing. its listed on the unorthodox site, but that was too big for my application. i can get you the size in the am.

 

Unorthodox Racing website page for their UDP on the 2000 Maxima:

...assuming that UR's UDP is the same diameter as your UDP.

This is one of the reasons I went with an OEM diameter on my light-weight crank pulley. Just saying.

Hope this helps. Good luck with the belt.

 

^where'd you get yours Rochester?

 

Direct from Unorthodox Racing almost 2 years ago. It doesn't seem that they have an OEM-diameter crank pulley anymore... in curiosity, I was looking for it after I posted that link for the OP.

When they had it available last, they were asking $250. I paid $200 for mine new. However, with hindsight, there are far better things to be spending two bills on than a lightweight crank pulley.

If you can do a crank pulley for $50 to $100, that seems more reasonable for what it is. People can and will disagree. That's just my 2-cents.

 

yea thats alot of money for little results...not like i have alot of power adders, etc for that to make THAT much of a difference. i could drop $200 on a wideband or a tuning unit to work towards a tune and get better results

 

Yeah I just ordered my an OBX one...just wanted to get fully bolted on before I tuned it come first of the year...

 

Ok that would be great...I ordered an OBX one, Im going to send them a message and ask them do they know the size as well...

 

is OBX a lightweight OEM diameter pulley?

 

lightweight....

 

*feels retarded about question after looking at thread title again* LOL

 

lol its all good, I couldn't see myself paying like $200 for one, im with you, im going to save that for my tuning items...

 

anyone?? I have the OBX UDP if that helps..

 

ralco makes a oem size lightweight one here is the link

Get OEM from Nissan. Most aftermarket's I've dealt with (all of them actually), tend to squeal. Nissan's do not squel unless they're actually loose.

 

yeah Im def gonna get good quality belts, I just wanna find out what the size of them are..I guess there measured in mm. I know if all things fail I can do the old string measuring trick..

 

Go to Nissan and ASK for OEM BELTS from the sales clerk, or order them online by using your make and model and year, that should get you where you need to be.

36 inches? Hell, I can't remember, but asking for OEM Maxima belts eliminates having to ask for a certain size.

 

Yeah I know but I still have to get the right size belt.

 

They will give you the right size if you order it from Nissan. Which is what I recommend.

 

Yeah but I have an OBX UDP and they prob will not know the specs of those....I can see if I got a stock diameter but I didnt..

 

I have a UDP (don't even know the brand ), and I am using stock belts becaue thay are superior.

Also, from posts 9 & 10, it's seems to me as if it's lightweight, and not a smaller diameter? Even then, the stockers will fit a smaller pulley, since both belts have quite a bit of adjustability.

The only time yo need to use a smaller belt is when you completely eliminate say the AC pulley, which is what I used to do in the winter. I believe it's a total of 2" smaller (50.8mm)

 

ooo ok good to know.....I thought since I was using the lightweight UDP i needed a new serpentine belt (prob spelled it wrong)...

 

I ordered this one if it helps...

Gates is working fine here. The only time it squeals is when I completely deluge the underside of the car speeding through a 6"+ puddle And that only lasts for a couple seconds.

 

yeah Gates always works good for me...

 

per the stickies, k060408...ill cross reference it for u at work tomorrow to let u know how much ours are. but id go with gates also....

 

man where did you find that at? as hard as i was looking!

 

search function lol. also, its in the link someone provided in here for unorthodox, and here
http://www.greghome.com/Greg%27s%20G...e%20Pulley.htm

 

yeah i see it now, and I like the way that they get the pulley bolt loose...might have to try that method..

 

the method in this site..

Did you get your answer yet?

 

this is the only part number that I know of as of right now...

 

Got the same ones work good got a squel but they say I need a new A/C Compressor I was like F33k wanted it to be something cheap!! And I read some where on here that somebody had a OBX pulley and it broke off, but hope it works well for you I wwent with the Ralco Pulley off ebay also!!

 

Yeah ive read different reviews about them and I know the positives and the negatives, I have also read some good things about them so...I will have to find out for myself....
