The crankcase oil vent system on the N52/N54 is one of its weakest and cheaply designed systems. We see crankcase vent issues on even stock engines but with more boost the problems are exponential. This Vargas upgraded PCV valve, and an oil catch can, are what the N54 engine needs and may alleviate most of your oil and boost leak issues. The PCV valve is supposed to let oil either return to the oil pan or pass through the intake manifold and get burned up in the combustion chamber. However, BMW used a weak plastic vent valve that doesn't seal well when under boost. Instead of  closing and venting the oil out of the intake, it's forced through this valve and into the intake and coating your valves with oil residue and carbon. Most boost equals more oil forcing its way by. This upgraded N54 PCV valve uses higher grade materials, including aluminum, to provide a better seal and prevent oil from entering the intake. It's an easy install and a must-have item when considering any turbo work.

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.

ARP is a company that prides itself on performance and durability, no matter the application. Offering the finest engine hardware money can buy is the driving initiative at ARP and this is evidenced by the staggering amount of satisfied customers and race teams the world over.

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)

VTT is proud to offer their billet replacement for the factory plastic vacuum tanks that store vacuum from the pump and use it to regulate boost via the solenoids. The stock plastic can and small plastic nipples on the stock cans have a tendency to crank over time, and if they leak you will get low boost, or no boost, and poor performance. These cans do away with the weak plastic cans while adding some pop, and color to your engine bay. These vacuum cans retain ALL of the factory provisions including mounting points but come with 90-degree fittings for easier routing of the lines VTT's cans are made of 6061-T6 aluminum, and anodized in 4 colors for beauty, and long life. They also knurl the cans for a very distinct look in the engine bay! VTT also designed these cans to complement their N54 Billet lineup – N5X Billet Oil caps, N5XBillet Oil filter housing caps, Billet coolant cap, Billet valve cover, billet oil cooler block off plate, and Billet Power Steering cap, and so on. All will have matching color These cans are offered in 4 colors – Red, Black, Blue, and Clear anodize The kit will include: 2 – Vacuum canisters (color of choice) 4 – billet 90-degree barbed fittings Requires the additional use of aftermarket vacuum line - Vacuum line not included.

This ARP main stud set is for the S54 3.2 liter, as found in all 2001 to 2006 E46 M3, as well as the 2006-2008 Z4 M Roadster and M Coupe models. Switching to the ARP main stud kit eliminates main cap walk and fretting, as well as protects the threads in your engine block. Each stud is made using the best materials, process, design and engineering, which exceeds even the most stringent racing and aerospace specifications. This S54 main stud kit includes hardened parallel-ground washers and aerospace quality nuts.

The studs are manufactured from 8740 chrome moly steel, heat-treated in-house to 190,000 psi tensile strength, and precision J-form threads rolled after heat-treat to create a fastener that has threads 1000% stronger than others. On the E30 M3, there's no reason to settle for anything less than the best, which is why we carry and use ARP fasteners and studs on our own BMW race cars.

ARP is a company that prides itself on performance and durability, no matter the application. Offering the finest engine hardware money can buy is the driving initiative at ARP and this is evidenced by the staggering amount of satisfied customers and race teams the world over.

Vargas has introduced their new Billet Power Steering pulleys for the N54 engine! A well-known issue with the N54 with Hydraulic power steering is the plastic pulley either hitting the subframe, or breaking on its own. This can result in the belt to be ejected from the pulley, and leave you stranded with no serpentine belt. This also increases the chance of sucking the belt into the engine through the front seal. Put an end to the dreaded plastic PS pulley issues with the VTT 100% Billet Aluminum PS pulley. These are constructed from 6061-T6 aluminum and anodize in one of 4 colors (Black, Red, Blue, and Clear) for a great look, and long-lasting finish. These weigh 11oz, very close to the weight of a stock pulley, and are lighter than the cast aluminum versions on the market.

VTT is proud to offer its very own Game Changer S55/N55 to B58 Coil conversion kit for the BMW S55/N55 platforms.

The solution is the BMW B58 ignition coils which are extremely robust and can support well over 1000WHP with no issues. This means a plug-and-play affordable solution that fits like stock, and looks AMAZING doing so! We designed our own 6061-T6 Billet bracket in a plethora of colors including matching shades for every S55/N55 Valve Cover. This means you can mix and match the color of the bracket with coil color, with VC color to truly tailor your engine bay to look exactly how you want it to! The kit comes with the following: 3 – Billet Aluminum Coil Brackets in the color of choice 6 – Plug and play VTT wiring harnesses 6 – Custom VTT stalks to convert the B58 coils to the S55/N55 head (We ensure proper spring length inside the boot for optimal spring-to-plug contact) *NOTE: Flash setting changes may be required when installing the conversion kit to ensure the proper function of the B58 coils with S55/N55 DME. This can be found in almost all flashing software settings such as MHD, Bm3, etc.* **NOTE: THESE BRACKETS FIT STOCK S55 VC, VTT S55 BILLET VC, and MOST N55 made after 2011. If you have an older N55 made before 01/2011. These may not fit. Purchase carefully as items that have been installed or attempted to cannot be returned.**

The OE crank bolts are grade 10 torque-to-yield bolts, designed for only a single use. For vehicles making stock power, the stock bolts are more than enough. Unfortunately, vehicles making more power than stock have experienced issues with the stock damper bolts coming loose and breaking, leading to engine and crank damage. 5150 AutoSport worked with ARP to create this ARP Harmonic Damper Bolt Set to address this issue. These upgraded bolts are stronger than the factory bolts and are designed to provide even repeatable torque load, preventing them from breaking and allowing them to be re-torqued as needed.

Vargas Turbo has released their very own BMW B58 vacuum/boost adapter. These go inline with the intake manifold fitting and provide a full boost/vacuum signal from the manifold. This fitting adds two 1/8" NPT bungs to accept any fitting that has 1/8" NPT threads. You can choose three configuration options: Fitting by itself Fitting with one 1/4" barb and one plug Fitting with two 1/4" barbs Once installed it tucks perfectly under your engine cover. These are perfect for running your PI switch off manifold pressure, which is much more accurate than the charge pipe, and they are also great for BOVs running the proper size line without having to drill a hole in your manifold. These do space out any sensors etc giving inaccurate readings like some of the other brands do.

This ARP Main Stud Kit is designed to replace BMW 11111735525 for the M50/M52/S50/S52 engines that were used in a variety of BMW models. One significant advantage of these main studs is their ability to prevent main cap walk, which can occur when the main caps shift or move out of position, potentially causing damage to the engine. In addition, ARP Main Studs can safeguard the threads of your engine block, providing an extra layer of protection against potential damage. When opting for main studs instead of factory bolts, it's important to note that the engine builder should mic the bores. Using studs may require a line hone to ensure proper fitment and alignment. A line hone is a machining process that can be used to resize and reshape the main bearing bores, ensuring that they are perfectly round and concentric. This is crucial for ensuring proper oil clearance and preventing premature bearing wear. By mic'ing the bores and performing a line hone if necessary, engine builders can ensure that the main studs are installed correctly and that the engine will perform reliably and at its best. Installation Instructions: To ensure accurate torque readings and proper thread engagement, thoroughly clean all threads in the engine block. If necessary, use an ARP chaser to chase the threads. Before installing any hardware, carefully inspect and clean it for defects, shipping damage, and proper fit, length, and dimension. Gently screw the main studs into the engine block by hand until they are snug. Install the main caps, checking for any binding or misalignment. Apply ARP Ultra-torque fastener assembly lubricant to the threads of the studs, nuts, and washers. Install the washers and nuts onto the studs and tighten them by hand. It is highly recommended to use the ARP Ultra-torque fastener assembly lubricant provided with the kit, as it provides consistent clamping force and reduces friction on the studs. Do not use motor oil or other low-quality lubricants. PRELOAD (TORQUE) RECOMMENDATIONS 7. Following the manufacturer-recommended torque sequence tighten the nuts in steps 1-3 Step 1: Tighten to 20 ft-lbs. Step 2: Tighten to 40 ft-lbs. Step 3: Tighten to 60 ft-lbs. With the included ARP Ultra-Torque fastener assembly lubricant

  • Improves Belt Tension Stability: Eliminates issues of belt slippage and instability under full throttle.
  • Prevents Premature Wear: Extends the life of belts, bushings, and tensioner springs.
  • Protects Engine Components: Safeguards the crank pulley and related parts from potential damage in case of belt failure.

This ARP Main Stud Kit is designed to replace BMW 11111735525 for the S14 B20, S14B23, S14B25, S14B27 engines found in the E30 M3. One significant advantage of these main studs is their ability to prevent main cap walk, which can occur when the main caps shift or move out of position, potentially causing damage to the engine. In addition, ARP Main Studs can safeguard the threads of your engine block, providing an extra layer of protection against potential damage. When opting for main studs instead of factory bolts, it's important to note that the engine builder should mic the bores. Using studs may require a line hone to ensure proper fitment and alignment. A line hone is a machining process that can be used to resize and reshape the main bearing bores, ensuring that they are perfectly round and concentric. This is crucial for ensuring proper oil clearance and preventing premature bearing wear. By mic'ing the bores and performing a line hone if necessary, engine builders can ensure that the main studs are installed correctly and that the engine will perform reliably and at its best.

Eliminate your squeaking accessory belt pulley and cracked drive belt with this upgraded accessory belt service kit! This kit includes the ECS Kevlar Reinforced Accessory Belt, tensioner assembly, and your idler pulley. ECS Tuning's Red Kevlar Accessory Belts are both an aesthetic improvement and a performance alternative to a traditional belt. Kevlar-reinforced belts experience less elongation over time minimizing the amount of belt adjustment needed as well as offering a higher shock and impact resistance compared to OEM-style belts. Refreshing the rollers and/or tensioners simultaneously is a great way to ensure all vital components of your drive belt system are functioning optimally for years to come!

For engine builders pushing the absolute limits of high-performance engineering, the ARP Custom Age 625+ Cylinder Head Stud Kit represents the pinnacle of fastening technology.

This specialized hardware is engineered specifically for ultra-high-boost applications, offering superior fatigue resistance and the unique ability to maintain its structural integrity under extreme temperatures that would cause lesser materials to weaken.
