Can someone tell me if pulleys are year specific?
If so what brands and what year. I got a 02 MCS and looking at getting a pulley for my car.

From what I've been told the pulley fits all years, the shaft is the same size. I know 02 through 04 is the same, I'm keeping my fingers crossed about 05.

 

I've been told that the Helix pulleys do not fit the 2.0 litre cars.

 

Maybe I'm missing something, but the MINI has a 1.6 liter engine. There has been talk the next generation engine (out in Oct 2006 or so) may be bigger, but from I've heard I think it will stay 1.6 liters -- but be turbocharged instead of supercharged. :smile:

 

Now now, don't confuse the newbies

The W11 engine has been using the same blower since inception. All current "supercharger reduction pulley's" will fit. Favorites are ALTA, Helix, and ET. 15%'s usually don't need a smaller/more flexible belt, however the 19% has always been a struggle keeping a belt on (esp. racing)

HTH,

Sorry, couldn't resist.

I knew I'd get a rise out of someone. Hoping for Eric.

 

Thanks for the info, just one more piece of wisdom I'll like to request - maybe two. For a 15% pulley - what is the belt part number for a stock belt either BMW or Aftermarket & which one is better?

Plus since I'm doing this upgrade solo - any suggestions, hints or advise?

Thanks

Advice: use good puller tools, take your time, read Randy Webb's How-To's, and use Loctite Red on your pulley screws. You almost can't jack up the engine too-high. Don't use the MINI belt tensioner tool unless you've welded on added reinforcements. I've found the Napa 25-060539 belt is spot-on perfect for 15% pulley usage, but it's not needed unless you're getting belt slip, which is almost, but not completely unheard of.

 

Dammit, you'll never get a freakin rise out of me with your *&^%$# comments! You're just pissing me off!

Oh, and uhh, the pulleys will go on any year MCS.

Thanks guys for your advice.

I'll definitely get that belt you suggested Ryephile.

Use loctite Blue it is recommended for 6mm-20mm screws and bolts.
