This kit covers many of the common wear items that should be changed any time the serpentine belt is being replaced. As these cars gain years and mileage the belt tensioners will also need to be replaced along with the actual belts. It won't do any good to replace the belt if the tensioners are worn. This kit will save you time and money over buying these pieces individually. This kit includes an updated hydraulic alternator tensioner for added reliability and longevity.

Underdrive Power Pulleys work to 'free up' horsepower. Any accessory that spins from the main drive belt is using up power. That's power that could otherwise be used to move the car. By giving some of that power back to the engine, you can make the car faster! It's like FREE HORSEPOWER !

Underdrive pulleys for your BMW will slow down engine-mounted accessories - the water pump, power steering pump, and alternator*. These systems contribute to 'parasitic losses' - power lost from what the engine could produce if it did not have these systems. Since less energy is used to move them, that power is transferred back to the engine and used to propel the car. Our pulleys give a 5-10% reduction in rotation, releasing up to 11hp on most BMW six-cylinder engines. There's also a small but noticeable improvement in throttle response too! We have done extensive testing and development work, both on and off the track, to ensure that the accessory systems function as they should. On our Racing pulley kits we actually underdrive certain components more so we feel our Street pulleys are an ideal compromise between power/torque gains, reliability, and system performance. Our pulley kits have been on the market for over ten years, and used in all of our own cars, with zero component failures related to their use.

Our pulleys are made from T-6061 aluminum and finished in a durable black hard anodize that is very resistant to wear, chemical exposure, and heat. We designed our pulleys to look similar to the factory parts but also to be stronger and, in most cases, slightly lighter too. For example, a Turner alternator pulley is less than half the weight of the stock steel pulley! With our hardcoat aluminum you will never have to worry about a serious failure of a stock plastic pulley. A 'stealth' approach to aesthetics was our goal and we let the results speak for the pulley design. Installation is straight forward and easy with simple hand tools. Removal of the fan is required for access to the front of the engine. Total install time for a 3-piece pulley set should be around 1.5 hours. A new longer belt is included and we also recommend replacing the separate A/C belt, belt tensioners, and the guide and deflection pulleys at the same time.

* Alternator Pulley Options
Bosch or Valeo? BMW built your car with either a Bosch or Valeo brand alternator. Unfortunately, the pulley is not the same for both brands. The brand is usually printed on the black plastic cover of the alternator but may be facing the frame rail or the ground. If you know which brand you have, select your option below and we'll send you the correct alternator pulley for your BMW. Don't know which you have? NO PROBLEM! We can send you both. The 2nd pulley costs $40 but you will receive a refund once we get the un-used pulley back (return shipping not included).

Stereo Systems. We offer our kits in two different ways: the full Power Pulley Kit with all 3 pulleys or a 2 pulley kit if you do not wish to underdrive your alternator (for large stereo systems or other battery-draining modifications). Our kits have been tested for compatability with the factory premium stereo systems (Harmon Kardon, etc). But any major alterations or upgrades from the factory system will work best with our 2 pulley kit and no underdriving of the alternator. For all stock stereo systems the 3 pulley set is recommended because the Turner alternator pulley will help make more power and is also much lighter than the stock pulley.

The camshaft position sensor is essential for assisting the engine DME by monitoring the camshaft's position. The data from this sensor is key to optimizing ignition timing and ensuring smooth engine performance.

Often referred to as the CMP sensor, this component is crucial for the overall functionality of the powertrain. A failing camshaft position sensor can cause a range of issues, including engine stumbling, hesitation during acceleration, power loss, and even starting difficulties or complete failure to start.

If you're not sure if your Vanos seals are bad then the only question you need to answer is if you've replaced them. Every unit from the factory came with the same failure prone o-rings and seals, even the re-manufactured units you can still get today. The only real fix is by replacing the seals and o-rings with material that is built to last in the oiled, extreme temperature environment found in these kits. 

A premium product replacement with easy to follow instructions makes rebuilding your Vanos unit a must. Even thought the power loss is barely felt it's the opposite result once you replace the seals, every car that gets rebuilt ends up wowing the customer and all of them saying they didn't realize what they lost. 

There are a number of symptoms that will plague your car as a result of these failing seals such as erratic idle, engine hesitation, stalling, and increased fuel consumption to name a few. If you've been chasing down any of these symptoms with no fix then this could be your issue.

While you 're replacing the seals in your Vanos unit it a good time to install anti-rattle spacers to tighten up the gaps in your stock assembly and get rid of that noisy Vanos clatter.

2001-2/2003 E46 330i/Ci, 2001-05 330Xi Stage 1 Performance Package
Peak Power Gain: +8hp / +10ft-lbs
Rev limit: 7000
Octane: 91 or higher

Our Stage 1 kit featuring a cold-air intake kit and matching performance software. The aFe intake is made with heat-blocking materials, reducing underhood temperatures and not contributing to heat soak of the air filter. aFe uses an oiled cotton air filter for maximum air flow and excellent filtration. The kit is supplied complete with heat shield, intake tube, sealing materials, hardware, and install instructions.

The software is tuned by BMW tuning whiz Jim Conforti and supplied with the Shark Injector. The Shark Injector is a do-it-yourself reflash tool that plugs into the OBD diagnostic plug in your dash. With the push of a button, it will copy your stock software and reflash your computer with the performance tune. You can set it back to stock at any time by following the same procedure.

Both of these items are packaged and work together. They provide a solid performance boost with a low upfront cost. For an excellent 'bang for the buck' upgrade, the software and intake are a great choice (TMS Underdrive Pulleys would also be on that list).

Related Upgrades: We are often asked what would complement our software and intake packages. Within any Stage, we recommend our Underdrive Power Pulley Kits. The Power Pulley Kit will under-drive the alternator, water pump, and power steering pump. Under-driving means each component is moving slower which requires less power. The saved horsepower is put back to the engine where it transfers to power at the wheels. Power gains are typically 10 horsepower at the wheels.

We also recommend upgrading the cat-back muffler for slightly more performance, lighter weight, and a more-aggressive sound. Our favorite E46 mufflers are the Supersprint, Borla, or Corsa exhausts. The Supersprint is the quietest and most like stock while the Corsa is the most aggressive (Borla being in the middle). You can expect a gain of 5whp with any of these exhausts.

2001-2/2003 E46 330i/Ci, 2001-05 330Xi Stage 1 Engine Upgrade Kit includes:
aFe Cold Air Intake (oiled cotton filter, heat shield, intake tube)
Shark Injector performance software

Applications:
2001-2/2003 E46 330i sedan, 330Ci coupe and convertible (check your driver's door pillar for production date data)
2001-2005 330Xi sedan

Shark Injector Performance Software
The enthusiast's choice for over a decade, the Shark Injector's performance is only equaled by its own ease of install! Tune your ECU at the press of a button simply by plugging into the under-dash OBDII diagnostic port, there is no removal of your car's computer; no laptop or cables required. What does the Shark offer?

  • Excellent horsepower and torque gains - peak: 18whp/11wtq, max: 22whp/16wtq
  • Faster and smoother throttle response
  • Top speed limiter removed
  • Extremely easy to install/uninstall
  • Reversible and reusable
  • Elevated 8,250 RPM rev limiter
  • Compatible with 91 octane; 93 recommended

Turner Motorsport Power Pulleys 
Underdrive Power Pulleys work to 'free up' horsepower. Any accessory that spins from the main drive belt is using up power. That's power that could otherwise be used to move the car. By giving some of that power back to the engine, you can make the car faster! We measured 10.7 whp at 6960 rpm and 8.1 lb-ft of torque at 5550 on a 1995 M3. Race pulleys deliver even more power. 

Another "no-downside" upgrade, we even include a new belt. Total install time for a 3-piece pulley set should be around 1.5 hours. We offer three options in pulleys:
1.) No alternator pulley included - for cars with big amps and powerful stereo systems that need the extra juice.
2.) Street Power Pulleys - our most popular option with no downside!
3.) Race Power Pulleys - delivering 15 "free" horsepower, this set underdrives the water pump, power steering pulley, and alternator for lower temps, less wear, and more power. Not for street use. 

 

 

Intake Air Temperature Relocation Kit
Looking to maximize your power gains? Add a Turner IAT Relocation to combat power-robbing heat soak - the only true plug-and-play solution available. Heat soak is a real plague on consistent power for a stock or tuned vehicle. Click here to read more about our IAT relocation kit.
