Tensioner Pulley for Main Drive Belt (Water Pump/Alternator/Power Steering) (more info)

This is the tensioner pulley, also known as the adjusting pulley and lower pulley. This pulley is mounted on the belt tensioner near the center of the belt assembly. The upper and lower pulleys are known to be the primary sources for 'belt squealing'. This pulley is also encased in rubber which will crack over time. If left without service the rubber could fail completely, chucking the belt and leaving you stranded. Replacement is a very simple procedure and can be done anytime the fan is off the engine (belt replacement, water pump service, alternator replacement, etc).

This pulley is mounted along with the hydraulic or mechanical belt tensioner but can be replaced on its own. It is used for the main drive belt on the M50-family engines (M50, M50TU, M52, S52, M52TU, M54, M56, and S54 engines). This is the same belt that covers the water pump/alternator/power steering systems. Replacement is a very easy procedure (requires fan removal) and will have your engine purring in no time. Belt replacement is strongly recommended at the same time.

Schrick Solid Lifter Conversion Kit (convert hydraulic lifters to solid lifters) (more info)

One major hurdle for a track-only car is the limitation of the hydraulic valve lifters in the M50, S50-US, M52, S52-US, M52TU, and M54 engines. These effectively limit your revs to 7200-7300 RPM as the valves 'float' at higher revs, leading to piston-valve contact. By converting to a machined solid lifter, and upgrading other areas of the engine, you can configure the valve train to withstand high RPM running. Not only can you tune for more power, you can help prevent damage during a mild mechanical over-rev.

This kit includes the mechanical spacers to convert hydraulic lifter tappets to solid lifters (like that of the S54 engine). The lifter bucket remains in place with the Schrick solid tappet replacing the original. These work on all M50, M52, S50, S52 and M54 engines and were proven in normally aspirated as well as supercharged engines. A custom camshaft is required.

Professional installation and setup is mandatory as these require complete assembly of the head, checking valve lash, then dis-assembly and machining of the Schrick tappet to spec. This kit includes enough spacers for 24 valves. We also carry individual parts, if you are looking for single pieces. This price is for a full set of 24.

Camshafts (Stock)

M52TU, M54 CAMSHAFT HELIX ALIGNMENT TOOL (more info)

When installing an aftermarket camshafts into a M52TU, M54 engine you need to remove the helix from the stock camshafts and install it on the new camshafts. But the helix does need to be installed with the proper orientation. The proper helix to camshaft placement is important for timing. We developed this tool that does both intake and exhaust camshafts.

Cylinder Heads

ARP S54 Head Stud Kit (E46M3 / MZ3 / MZ4) (more info)

Virtually every top professional BMW engine builder relies on ARP Pro Series head studs, particularly on the S54 3.2 liter engine. ARP uses a premium grade 8740 alloy that is rated far superior to "aircraft" quality. Each stud is heat-treated to 200,000 psi, ensuring complete heat penetration. ARP studs are threaded after heat-treat, which gives them 1000% (that's ten times!) better fatigue strength than studs threaded prior to heat-treat. Threading the studs after heat-treating is more difficult and costly (as it's harder on tooling) but the results are well worth the effort. These simply are the best S54 head studs we've found for the E46 M3 6 cylinder engines, and we highly recommend them in both the racing and forced induction arena. (Due to the additional clamping force between the head and block, these are IDEAL for turbo charging and supercharging!)

Converting from the factory BMW head bolts to head studs makes it much easier to assemble an engine, especially a racing powerplant which must be serviced frequently (and quickly!), and also ensures proper alignment of the head and gasket. Head studs also provide more accurate and consistent torque loading. Here's why: When you use bolts to secure the head, the fastener is actually being "twisted" while it's being torqued to the proper reading. Accordingly, the bolt is reacting to two different forces simultaneously. A head stud should be installed in a "relaxed" mode -- never crank it in tightly using a jammed nut. If everything is right, the stud should be installed finger tight. Then, when applying torque to the nut, the stud will stretch only on the vertical axis. An information sheet is provided with each set. Kit includes everything pictured -- 14 head bolts, washers, bolts and assembly lubricant.

These head studs fit the following BMWs/engines
2001-2006 E46 M3 coupe & convertible
2001-2002 MZ3 M Roadster & M Coupe (with S54 engine)
2006-2008 MZ4 Z4 M Roadster & M Coupe

Genuine BMW Exhaust Camshaft Position Sensor - E46 M3 E39 M5, MZ3, MZ4, Z8 (more info)

Sensor for: Exhaust. One weak point on BMW engines for years has been the cam position reference sensor. On the S54 engine in the E46 M3, M Roadster, and Z4M, there is one sensor for each cam. The sensor tells the computer the position of the cam on cylinder #1. The computer relies on the sensor's information to set injection timing and VANOS control. When a sensor goes bad, the computer loses track of what position the cam is in. While the engine will continue to run (taking its measurements from the crank position sensor), the entire system is thrown off. The engine may stumble or run rough, but not misfire, and there will be a loss of performance.

Each cam sensor also doubles as a sensor for the VANOS. So when the sensor goes bad, the VANOS will revert to a safe mode and will not advance.

While the engine will still run with a faulty cam position sensor, it's not running in its finest tune. The DME will have fault codes related to the cam sensor or for the VANOS. This is the Original BMW sensor with a new o-ring.

Oil Pressure Switch (fits most BMWs) (more info)

Having your oil pressure light come on can mean very serious problems. Or it could just be this switch that fails several times over a car's lifespan. By no means should you ignore the warning light but replacing this sensor could be the actual culprit. The other problem with this switch is that oil can leak past its seal. With the oil under a lot of pressure at this point, the oil loss can be a serious concern. It's a simple replacement when doing most oil change work.

Constant Pressure Valve for E46 M3, MZ3 (S54), and Z4 M (more info)

Oil leak on the E46 M3? The constant pressure valve, or oil pressure relief valve, is the most likely reason. This screw valve, located on the exhaust side of the engine block, has a steel o-ring that becomes flat over time, allowing oil to leak around it and down the back of your engine, transmission, undertray, and eventually to your driveway. If you see an oil leak around your transmission and think it's the rear main seal or from the oil pan, try replacing this first. Replacement is the only remedy as the washer on the screw has deformed in shape. The constant pressure valve helps to keep oil up in the cylinder head so you want a direct replacement part - not an aftermarket 'solution'. This is an Original BMW part. One required.

Applications:
1993-1999 Euro E36 M3 (S50 Euro, S52 Euro engine)
2001-2002 MZ3 M Roadster, M Coupe (S54 engine)
2001-2006 E46 M3, E46 M3 CSL

Idle Control Valve - M50, M52, M52TU, M54 (more info)

Rough or hunting idle? Stalling? Sputtering? These are all symptoms of poor fuel delivery or a vacuum leak in your intake system. The idle control valve is one of the areas that you can check to fix these issues. The ICV is basically a electrically-driven throttle body that regulates the air/fuel mixture at light throttle openings. Over time, the ICV can become gummed up with oil and carbon, resulting in slow or blocked operation. Worst case, the electric motor inside will freeze which will stall the engine.

The ICV will typically need to be cleaned or replaced every 100k miles. It can be cleaned with carb cleaner but for seriously dirty or old ICVs you may want to replace the whole unit with a new one. There is also a hard rubber seal between the ICV and the manifold and this should be replaced as well. You may also want to replace the Crankcase Vent Valve as it can also fill up with oil and carbon and replacement can be done at the same time as the ICV.

Add a new ICV to your M50 Manifold Upgrade to save time and money!

OBDI Conversion Part - Turner Motorsport OBD-I 3.2 Coolant Hose Adapter (more info)

The TMS Coolant Hose Adapter is needed when you are upgrading to OBD-I (1992-1995 components) on a 3.2 or 2.8 liter engine. These earlier engines use a fitting to secure the heater hose to the front engine cover. The 3.2 and 2.8 liter engines do not have this fitting. This is also needed if you are doing an E30 3.2 or 2.8 engine conversion using OBD-I electronics.


There is no way to affix a coolant hose to the 3.2L M3 Engine in stock form.	Apply two-part epoxy (Included) and insert the TMS Coolant Hose Adapter.	Tap into place with hammer to assure a watertight seal.
Once installed, this is how the fitting should look, ready to accept the coolant hose.	Clean off any excess epoxy. Once installed, the fitting appears to be a factory part.	Included with the kit: TMS Coolant Hose Adapter, two-part epoxy w/mixing cup, wooden mixing stick.

OBDI Conversion Part - Water Temp Sensor Wiring Adaptor (more info)

The TMS Water Temp Sensor Wiring Adaptor is needed when you are upgrading to OBD-I (1992-1995 components) on a 3.2 or 2.8 liter engine. These earlier engines use two separate water temp sensors in the head, one for the ECU and one for the instrument cluster. Most of the 3.2 and some of the 2.8 liter engines do not have two holes drilled in the head for the early water temp sensors. This is due to the fact that the 3.2 and 2.8 engines used a combined water temp sensor. So we designed a easy to use plug and play wiring harness. The benefits are: No cutting and splicing, no trying to fine plugs and pins. We also suggest using TMS "3.2 in a 3.0" Coolant Hose Adapter P/N: TEN9931007 to make your life easier.

Fan Clutch - Many 6 Cylinders (more info)

This clutch engages the belt-driven engine fan when the engine is warm/hot, and dis-engages the fan when cold/cool. These commonly fail, causing the engine fan to not spin fast enough (or at all) when your car is stopped in traffic, causing engine to overheat.

This fan clutch fits many 6 cylinder BMWs, including the following::

1989-1994 E32 735i/iL

Fan Clutch for M20, M30, S14, S38, M42 & M44 Engines (more info)

Has your fan clutch failed or is beginning to fail? A failing fan clutch will cause the engine fan to either not turn at all, or to turn very slowly and lifelessly, providing insufficient cooling for the radiator (especially noticable while idling or in stop/go traffic). This fan clutch, with 32mm connecting the clutch to the waterpump, fits many BMWs from the 80's and 90's (see list below for full list of BMW fitments).

Fuel System

Bosch 24 lb Fuel Injector - Blue Top (Bosch # 0-280-150-947) (more info)

The 24 LB Bosch blue-top injector is used in many high performance vehicles which require a good amount of fuel. This fuel injector is most commonly used on Ford Mustangs, and other domestic V8's, which require a healthy amount of fuel. This is a genuine Bosch fuel injector, Bosch part number 0-280-150-947 / Ford Motorsport part # F1TE-D5A. Sold individually, so be sure to order enough for your application.

We use this particular Bosch injector on modified E36 M3 BMWs, which require more fuel to balance the air/fuel ratio after adding modifications such as cold air intake, cams, headers, etc. During our own testing we found the stock BMW injectors reach their limits with only a few modifications (intake, HFM, and basic chip). Anything more than these basic upgrades and you will need larger injectors. In the packages and kits we have developed we found the 24# pound fuel injector to be ideal – not too large and not too small. With the correct software you can run your engine without fear of the mixture being too lean. This is the fuel injector we use in our 3.2 OBD-II kits as well as in our 3.0/3.2 OBD-I systems. This injector, and the software we have developed when using them, are designed for the E36 M3 BMWs only (We have not seen a reason to use them on a E36 325 or 328).

Note: you should never use a fuel injector that is not properly calibrated to your engine with the proper software! Doing so can seriously damage the engine, ECU, or injectors.

This item fits the following BMWs:
1995-1998 E36 BMW M3 - Manual Transmission Only

ARP Connecting Rod Bolt Kit - E36 M3 S50/S52 (US only), E46 323/325 and more (see list) (more info)

Set of 12 ProSeries connecting rod bolts, made by ARP -- the world leader in fastener technology. Each bolt is made of ARP2000 material, which exceeds the strength of 8740 Chrome Moly, and is able to achieve clamp load at 220,000psi. ARP2000 fasteners are used widely in motorsport and drag racing as an upgrade from 8740 Chrome Moly in both steel and aluminum rods. These are simply the best connecting rod bolts available, making them ideal for ultra high performance, racing and forced induction applications.

This set replaces the factory BMW rod bolt number 11-24-1-739-728 (11241739728) which measures 44mm in length. The 44mm BMW rod bolt was used on all US spec E36 M3 (3.0 and 3.2 liter), 1999-2000 E46 323i/323Ci, 2001-2005 325i/325Ci, Z3 1.9,2.5 and 3.2, as well as Z4 2.5. It was also used on SOME of the M50 2.5 liter engines from 1992-1995 -- but check before ordering! Opened ARP bolt kits are not returnable. If your M50 2.5 liter engine has 53mm rod bolts, you will require kit part# 201-6301 instead.

These ARP connecting rod bolts fit the following BMWs:
1992-1995 E36 325i/is *** with 44mm rod bolts only ***
1995-1995 E36 M3 S50 3.0 liter (US model)

If you are overhauling your coolant system, now is the time to consider preventative replacing this expansion tank. These are known to go bad, causing a leak which can leave you stranded. If your car has over 100k miles and hasn't had one of these replaced, we highly recommend replacement.

Need a new coolant level sensor too? If your coolant level sender is bad, your on board computer will constantly display a "low coolant" message (unless your coolant is actually low...). If you're replacing your expansion tank, now is a great time to replace this failure prone sensor. If you want a new coolant level sensor, simply choose from the option below.

Thermostat With O-Rings - E46 M3 (more info)

Replacement stock thermostat for E46 M3, Z3M w S54 engine, Z4M. The thermostat can be replaced on the E46 M3 without removing the water pump. This can save you money if the pump still has life left on it but the thermostat needs to be done now. Symptoms of a bad thermostat include an erratic temp gauge and a fault code. When replacing the thermostat, there are three o-rings that will likely need to be replaced – between the thermostat and the water pump housing, and two on the coolant tube going to the head. We also recommend new hoses, clamps, and BMW coolant. Replacement should take about one hour.

Note: even though this can be done without replacing the water pump, the job involves removing the same items to access this area. And opening the thermostat housing will spill a lot of coolant. In other words, if you don't replace the water pump at the same time, you're going to repeat this process all over again when the pump needs replacing. We offer a complete overhaul package that covers everything you need if you want to it all at once.

This item fits the following BMWs:
2000-2001 E46 3 Series M3 M3 Convertible 2000-2006
2001-2002 Z3 Roadster / Coupe Z3 M Roadster Z3 M Coupe w S54 Engine

Underdrive Power Pulleys

Turner Motorsport Power Pulley Kit - E36 325/328/M3, E34 525i(M50), MZ3(S52) (more info)

Underdrive Power Pulley Kit for E36 325i (1992-1995, E36 323i/328i 1996-1999, E36 M3 1995-1999 (US models only), E34 525i (1991-1995 w/o servotronic steering), M Coupe/Roadster (1998-2000 with S52 engine)

As used on our racecars and street cars, these are engineered not only to be the best pulley kits on the market but also to provide the best compromise between performance and reliability. Specifically, we have designed them to underdrive the water pump, power steering pump and alternator*. Adding these is like getting FREE HORSEPOWER - there are no downsides and underdriving each of these accessories has been proven safe through years of on and off-track use. We do not believe it is safe to change the crankshaft pulley due to the potential harm to the crankshaft. These kits provide a 10%-20% overall reduction in driving your car's systems and have been dyno-tested with a gain of up to 11hp.

Kit includes water pump, power steering, alternator pulleys and belt. The T-6061 hard anodized aluminum pulleys account for a 10 to 20-percent decrease in accessory speeds, reducing the load on the engine but still maintaining a safe margin for reliability on all components. Installation involves removing the fan for easy access to the front of the engine. The main drive belt comes off easy and each pulley is mounted with Allen head bolts. Typical installation time is 1.5 hours. New main drive belt is included. The pulleys were good for 10.7 hp at 6960 rpm and 8.1 lb-ft of torque at 5550 on the 1995 M3.

*Alternator pulleys - we offer two kits, one for the performance minded individual and one for the serious audiophile. If you have a significant additional load on the alternator, from aftermarket audio amplifiers, you will not want to underdrive the alternator. Thus, we simply lighten that pulley rather then underdrive it. Choose from the menu below if you have a stock or an upgraded stereo.

BMW used both BOSCH and VALEO brand alternators, which use different pulleys. If you know which you have, select your option below and we'll be sure to send you the correct alternator pulley for your BMW. Don't know which you have? NO PROBLEM! Simply tell us you don't know which style alternator you have, and we will send you both pulleys. This option costs $64, but you will get a $64 refund once we get the unused pulley back. If you know what type of alternator you have please indicate it by selecting below.

This underdrive pulley kit fits the following BMW:
1991-1995 E34 5 Series 525i without servotronic steering
1992-1995 E36 3 Series 325i, 325is, 325ic

As used on our Project E46 M3 street car and our Grand Am Cup race car these are engineered not only to be the best underdrive pulley kits on the market, but to provide the best compromise between performance and reliability! Specifically, we have designed these "stock looking" pulleys to underdrive the water pump, power steering pump and alternator. Adding these is like getting FREE HORSEPOWER - there are no downsides and underdriving each of these accessories has been proven safe through years of on and off-track use. We do not believe it is safe to change the crankshaft pulley on engines with harmonic balancers due to the potential harm to the crankshaft. As such our pulley kit for the E46 M3 does not replace the crank pulley, only the auxiliary pulleys. These kits provide 10%-20% overall reduction in driving your car's systems and have been dyno tested with a gain of 10hp on the E46 M3. Click Here For E46 M3 Dyno Chart.

Turner Motorsport Power Pulley Upgrade Kit - Z3 (not M) (more info)

Underdrive Power Pulley Kit for Z3 2.8 (1997-2000), Z3 2.3 (1999-2000), Z3 2.5i (2001-2002) and Z3 3.0 (2001-2002)

As used on our racecars and street cars, these are engineered not only to be the best pulley kits on the market but also to provide the best compromise between performance and reliability. Specifically, we have designed them to underdrive the water pump, power steering pump and alternator*. Adding these is like getting FREE HORSEPOWER - there are no downsides and underdriving each of these accessories has been proven safe through years of on and off-track use. We do not believe it is safe to change the crankshaft pulley due to the potential harm to the crankshaft. These kits provide a 10%-20% overall reduction in driving your car's systems and have been dyno-tested with a gain of up to 11hp.

Kit includes water pump, power steering, alternator pulleys and belt. The T-6061 hard anodized aluminum pulleys account for a 10 to 20-percent decrease in accessory speeds, reducing the load on the engine but still maintaining a safe margin for reliability on all components. Installation involves removing the fan for easy access to the front of the engine. The main drive belt comes off easy and each pulley is mounted with Allen head bolts. Typical installation time is 1.5 hours. New main drive belt is included. The pulleys were good for 10.7hp at 6960 rpm and 8.1 lb-ft of torque at 5550 on the 1995 M3.

*Alternator pulleys - we offer two kits, one for the performance minded individual and one for the serious audiophile. If you have a significant additional load on the alternator, from aftermarket audio amplifiers, you will not want to underdrive the alternator. Thus, we simply lighten that pulley rather then underdrive it. Choose from the menu below if you have a stock or an upgraded stereo.

BMW used both BOSCH and VALEO brand alternators, which use different pulleys. If you know which you have, select your option below and we'll be sure to send you the correct alternator pulley for your BMW. Don't know which you have? NO PROBLEM! Simply tell us you don't know which style alternator you have, and we will send you both pulleys. This option costs $64, but you will get a $64 refund once we get the unused pulley back. If you know what type of alternator you have please indicate it by selecting below.

Turner Motorsport Racing Pulley Set - E46 M3 (more info)

TMS E46 M3 Racing Pulley is designed to achieve three goals: gain horsepower, reduce alternator and power steering pump wear, and lower power steering fluid temperatures. Due to constant high revolutions of the S54 power steering pump when on the track, we designed our racing power steering pulley to slow down the pump. This lowers fluid temperatures, resulting in less wear to the pump. This kit also includes a large alternator pulley, which also reduces wear. Kit uses our street water pump “under drive” pulley. All of these working together produce a significant gain of over 15 horsepower. The pulley has been track tested on our Grand Am Cup M3’s and dyno-tested. This is strictly for race/track cars only, due to the size of the alternator pulley the proper voltage cannot be maintained at low RPM.

Note: We sell pulleys separately incase you have special needs. Simply give us a call, or drop us an email.

Vanos Unit with Solenoid - Rebuilt - S54 - E46 M3, Z3M, Z4M (more info)

The E46 M3, the Z3 M Coupe/Roadster and the E85/86 MZ4 Coupe/Roadster all came equipped with the S54 engine which was a much more complex engine than the earlier US Spec M3 had. The vanos on the S54 also evolved into a more complex unit and has it's own set of inherent problems that many S54 owners will run into eventually. The S54 Vanos controls both the intake and exhaust camshafts to improve performance, torque, idle characteristics and emissions. A high pressure (1200psi) control system is used to ensure responsive and accurate camshaft adjustments required by the high performance M engine. The back of the vanos houses a radial oil pump to produce the 1200psi of oil pressure. This pump is mechanically driven by a hub on the exhaust camshaft, which is one of the common failure points on this engine. The vanos also uses 4 solenoids which are attahed to the bottom of the unit in a non-rebuildable aluminum case. These solenoids are very sensitive to oil pressure and can easily become clogged or damaged over time due to contaminates in the oil. We highly recommend changing the oil every 5000 miles and only using the BMW 10w60 High Performance oil to prolong the life of the vanos. Typically the S54 vanos does not exhibit the common diesel rattle under normal operation. If you notice that your engine has suddenly become noisy we recommomend that the car not be driven any more than necessary until the source of the noise can be determined. This S54 vanos comes fully rebuilt with brand new solenoids and solenoid valves. This is the exact same package the dealers sells, but at half the cost.

Water Pump - M50, M52, M52TU, and M54 Engines with Metal Impeller (more info)

The early M50/M52 engines had a serious weak point: the water pump. BMW originally used a plastic impeller in the waterpump. This would degrade over time and eventually break apart. Your car overheats immediately. This water pump is an updated one with a metal impeller. BMW has since released a water pump with a composte impeller that does not have the same issues and is just as reliable as the metal impeller version. But for piece of mind, the metal impeller is tough to beat.

This waterpump fits the following BMWs:

Your car overheats immediately. This water pump is the latest updated part with a composite impeller. The composite is stronger and lighter than the less-expensive metal impeller version. And it does not suffer from the problems of the early plastic design.

This waterpump fits the following BMWs:
1992-1999 E36 3 series - 323is, 323ic, 325i, 325is, 325ic, 328i, 328ic, M3 3.0 (S50/US), M3 3.2 (S52)
1999-2000 E46 3 series - 323i, 323Ci, 328i, 328Ci
1997-2000 E39 5 series - 528i
1999-2000 Z3 Roadster/Coupe - Z3 2.8, MZ3 (S52)

Water Pump - M52tu, M54 (Original BMW) (more info)

This Original BMW water pump is the latest updated design with a composite impeller. The composite material (similar to Kevlar) is much stronger than the problematic plastic impeller from past water pumps. And it's lighter than the aftermarket metal impellers so that means less strain on the bearing. For an OE/OEM replacement, we have found that this is the highest quality and longest lasting waterpump available.

This waterpump fits the following BMWs:
1999-2006 E46 3 series - 323i, 323Ci, 328i, 328Ci, 325i, 325Ci, 330i, 330Ci

Water Pump Pulley - E46 E39 Z3 (more info)

This is the stock water pump pulley that mounts between the engine fan and the water pump. We have seen these plastic or composite pulleys crack around the mounting bolt holes. If left un-noticed the whole pulley can fall apart which will immediately disable the car and possibly leave you stranded. It can also break while performing other work around it such as removing the fan, replacing the water pump, or even just replacing the belt. Replacing this pulley while doing the water pump can be a good preventative measure.

This item fits the following BMWs:
1999-2005 E46 BMW 323i 323ci 325i 325ci 325xi 328i 328ci 330i 330ci 330xi
