Sad update on my part...

Initially, I was enjoying the changes from adding the UD pulley. I had put on about 500 miles or so and started noticing a couple of drops of oil under the car when I moved it. Also started noticing a slight vibration so I called the mechanic that installed it and he came over to check it out. Turns out it wasn't seated properly and was wobbling. I should have known better and taken it to a shop to have done. I told him to just put the stocker back on. I asked if it was still leaking, thinking it was coming from the front crank seal.

Anyway, he puts the stock pulley back on and says it's all good for now. I get the splash panel washed out and spray down the front of the engine to remove any residual oil... That night I'm STILL smelling oil so I crossed my fingers and took it to the dealer. Sure enough, the front crank seal is bad now. They replaced it under warranty and I'm just hoping that no other damage was done by the bad install.

Just a reminder that when you have bits installed, make sure that you know everything is done correctly. I feel like an idiot now, and it's going to take a little while before I trust my car again to be free from defects. I hate this feeling...

This in no way should reflect on NST. Their service and product were great, I just got unlucky with a bad install. Now I have an expensive paperweight as the inner sleeve has a nice uneven groove in it from where it was spinning incorrectly.

I have this same worry. It took 2 of us to get the crank pulley bolt to let go. Im sure that places a lot of pressure and stress on the front seal. I believe Stillen actually recomends pulling the radiator off and using an impact. If anyone has installed the NST products or the Stillen pulleys I would recomend keeping a close eye on the front seal. This is not a reflection of the great parts produced by NST or Stillen, just the crazy torque spec's of the crank bolt. Nissan must have put it on with a impact gun from a tank assembly line. I have the NST products and the quaility is fantastic.

Which belt did you use? The stock belt or the smaller Gates belt? Just curious...

I used the shorter Gates belt. I'm glad I kept the stock belt though now that I had to put on the stock pulley. So far since getting it back from the dealer I see no leaks but can still smell some oil. There must still be some on the block where I couldn't reach with the spray nozzle. Hopefully it will burn off soon and I can have some peace of mind.

Are you going to go back to the NST parts?

I'm sorry to hear about your installation issue there :mad:

And I appreciate the kind words regarding our product and service.
Feel free to contact me by phone and I will see what I can do for you regarding your NST Pulley Kit.

Professional installation, from someone who has experience with installing pulleys, is highly recommended.

Thanks again, best of luck to you and your car with all your future projects.

I installed on my g37 S and you can tell a difference .. Thanx !!

Glad to hear it :tup:

I was on the UH campus today and had to do a double take when walking past someone, they had on a NST shirt from your shop.

That's very cool :happydance:

We have a lot of local customers in the Houston area who come to our meets and events.
A lot of these people support us by picking up a Tshirt or two!

Thanks for posting that!!!

We can build such pulleys for any customer on a special-order basis, in fact we do this quite often.

Thank you for the recent inquiries, phone calls, and IMs everyone. Your support of our brand and products is much appreciated.

I put a mini-blurb in my journal:

Also to note: my MPGs went up too, but I did install a few things at the same time. No complaints from me so far though, good work NST.

I'm glad to hear that you're enjoying your new toys!

Problem
 

Mike just got my pullies, but everyone here, says i should have gotten stillen or wonn't put them on. can i bring my car to you and have you guys hook me up?

Well if you read the reviews from the people here who actually own and use NST pulleys... these people have nothing but positive reviews for our products.

Please give us a call during normal business hours and we would be happy to set up an appointment for your installation at our shop.

Thanks again, good luck and have fun with all your projects!

Anyone else?!

My pulleys are being installed next week with my headers. Will post dyno after install.

Hope you got your pulleys on and are enjoying them!

This thread definitely needs more pics :tup:

Got the car back last night after the headers and pulleys were installed. What a difference It goes like a bat out of hell. It gets to 80 km much quicker from a standing start. Its scary fast when you put all the mods together. My mechanic who installed the parts could not believe how fast it excelerates. now. 4.08 gears plus Stillen G3 intake, CBE, cats, headers, with the underdrive pulley and overdrive pulley on the altenator with a cobb tune. Car will be dynoed next week. The voltage did not move on the gauge 14.3 to 14.4.
12.6's here we come !!!

Can you guys recommend online sites to order the Gates belt? I haven't checked with my local AutoZone yet.

Mike, I'm going to order the pulleys in a few weeks and have my dealer install it. Do you guys still carry the gray color?

You should be able to locate the belt at your locat AutoZone, Oreilly, PepBoys, etc.

And yes, we will always have the gray and red kits available :tup::tup:

Glad to hear your review. Good luck at the track!

:driving:

In for dyno results on a 370z, seems like a cool mod and I can always sell them if and when I go F.I. $200 is a great price as well.

Sweet... AZ didn't have it, and OReilly ordered one and should come in Tuesday. I can't wait to get these pulleys!!! :excited:

what are you going to do when you put the S/C on.. do these pulleys work with the GTM S/C?

so belts and pulleys what else do i need and how much of a hp tq gain we talking here

IF/WHEN you ever go with a supercharger that is driven off the crank pulley, you can remove the underdrive crank pulley and contact NST for a lightweight OEM diameter crank pulley, or install the OEM Nissan pulley.

:tup::tup:

You don't need anything else, no other modification of any sort is necessary. And as far as HP, TQ, and throttle response goes... please check page one of this thread. This is a VERY noticeable performance booster.

:driving:

That is the worst looking dyno graph I have ever seen in the 13 years I have been involved in getting my cars dynoed. Is that erratic power and torque as well as curve typical behavior for of a BMW engine???

Do you think these will pair well with a turbo system???

Not entirely sure. This was the first 335i we have put on a dyno, and it was not running the OEM BMW map. But one thing is clear, the NST pulley made a noticeable difference across the RPM band.

We'll be testing with a bone stock 335i in the next couple weeks and will compare the behavior.

:driving:

Yes, very well. Underdrive pulley kits like this one usually free up more power on a turbo car compared to n/a setups, and help with spool times and overall response.

:tup:

does anyone know where i can go to locate a gate belt in ny

I got mine from O'Reilly Auto Parts. They didn't have any in stock, but ordered one.

BTW... I received the pulleys and hope to install it next week.

Brief Review
 

The pulleys and new belt were installed this morning. It took about a couple of hours at the dealership.

Installation Complications
The tech had to sand the crank pulley to get it to fit properly. He says there is a difference in diameter of the hole which required a bit of work. It's a good thing he didn't hammer it down.

Dealer Install Cost
The install bill would've been under $200, but the tally was $363! My dealer gave me a slight discount and dropped it to $324.

Initial Impressions
Voltages are normal with virtually no change from stock. Slightly more smooth and lighter acceleration and throttle response. SRM throttle blip is quicker. I'll give it a few days to see what MPG difference is (20.6-21.6 MPG stock). Overall a great starter mod!

Good info on the complications ^
Been looking at this for my next mod, but not excited about the labor cost at $363 for a part that runs, what $200. But the gains may out weigh to total cost.
