Includes a full set of polyacrylic intake and viton exhaust valve stem seals! Looking to replace your valve stem seals due to leaks, cracks, splits, or even during an upgrade of your camshafts, valve springs, or valves? Supertech valve stem seals are the way to go! This cheap but effective seal replaces the stock BMW seals that are notoriously prone to issues due to heat cycles and chemicals which cause the seals to become weak and brittle. Supertech seals offer a significantly longer life span and are resistant to both heat and chemicals thanks to their use of Viton or Polyacrylic construction (dependant on valve type). That means less time in the garage and more time on the street or track! These seals are also great for anyone who is looking to upgrade to dual valve springs thanks to the seal's overall thinner outer diameter! Guide OD: 8.8mm/.347" Seal OD: 12.2mm/.480"

Stock OEM hydraulic valve lifter for the M52, M54 and S50 S52 engines. These lifter buckets can last 150,000+ miles but then they no longer fit on the valve stem correctly and a ticking or knocking noise can result. If the lifter is no longer seated correctly, it can lead to the valve not opening correctly. Replacement is straight-forward but requires special tools for working with the camshafts.

When doing any sort of repair or maintenance there is no replacement for genuine factory parts. Turner Motorsport carries the Genuine BMW brand with pride and has the parts you need to complete your next project with confidence.

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)

Upgrade your BMW engine's performance with the Athena Cut Ring Head Gasket. This gasket replaces BMW part # 11121726619 and 11121726617 and is specifically designed for M50 & M52 iron block inline 6-cylinder engines found in E34/E36 chassis. Standard OEM & MLS gaskets can only handle a certain amount of cylinder pressure before they start to leak, making the Athena Cut Ring Head Gasket the recommended choice for applications making 16+ psi. A compression leak passing the head gasket can cause a range of issues, including engine overheating, loss of power, misfires, and in severe cases, catastrophic engine failure. Athena's gasket is crafted with premium quality reinforced M0115, an asbestos-free material that's original equipment approved and renowned for its superior quality. The AISI 304 stainless steel Cooper Rings bite into the aluminum head, providing maximum sealing capabilities around the cylinder bore and optimizing engine performance, even on engines with nitrous and/or turbo applications that exceed 2-bar boost. Before installation, it is crucial to have the mating surfaces of the cylinder head and block professionally cleaned and resurfaced to ensure they are completely flat. Please be aware that the gasket should have a size that is 0.5mm to 1mm larger than the piston. For example, if the piston measures 84mm, then the gasket should be the next size up, either 84.5mm or 85mm. Installation instructions: Make sure that the engine block and cylinder head surfaces are clean, flat, and free from any debris, oil, or coolant. Install the Cut Ring gasket on the engine block and ensure that it is properly aligned. Avoid twisting or bending the gasket during installation. Place the cylinder head on top of the gasket and install the head bolts or studs in their correct positions. Follow the manufacturer's recommended torque specifications and tighten the bolts or studs in the proper sequence to ensure even clamping force across the gasket. After the initial tightening, re-torque the head bolts or studs after the engine has been started and then allowed to cool to room temperature. This will ensure that the gasket is properly seated and compressed. It is recommended to not use any additional sealant on the MLS gasket, as it is already coated with a Viton rubber sealant. Using additional sealant can hinder the performance of the gasket.

Upgraded valves designed for high horsepower applications! Our valves are not finished from generic blanks rather they are specifically designed for each and every application. We work relentlessly, testing and researching every aspect trying to improve the air flow of our designs. With every valve design, we strive to maximize durability through higher fatigue resistance and tensile strength. Each valve tip is hardened beyond 52HRc. It’s unlikely you will find any of our competitor’s valves with stricter dimensional tolerances than our Supertech valves. Combine that with finished seats with equally strict run out tolerances and you won’t find a better sealing, better performing and easier to install solution anywhere! Optimum high flow rates are achieved by ensuring that our valves are manufactured with the best angles for each application. We consider back cut, under cut and valve head angles for each application to produce the optimum high flow rates for each application. In 2006 we introduced our stem Superfinishing as a standard addition to all of our valves at no additional cost. When our Superfinish is combined with our Black Nitrided valve, it reduces the surface roughness to 1/3 of our chrome coated valve. The end result… unsurpassed performance and durability. Our exhaust valves are made from EV16 (21-8N) or EV8-Nb/w for greater strength at higher temperatures. Black Nitride Coating: This is a hardening treatment that has been steadily growing in popularity over the last several years. These black Nitride coated valves feature harder surfaces and smoother finishes, providing less friction and subsequently longer life. Please see below for more benefits of our Black Nitride valves. Head Diam: 31.50mm Material: Black Nitride Groove Type: Single Groove Length: 105.65mm Stem Diam: 5.95mm Size: 1mm+

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

5150 High Performance Coated Main Bearing Sets are made for the demands of high performance engine builds. Treated shells and coated by Calico to reduce friction, these bearings allow your engine to generate more power and resist "spinning" under stress. These coated bearings also have thermal resistant properties that not only perform in high HP applications like forced induction or race use, but also help prevent sudden engine failure in the event of oil pressure loss. 5150 bearings have proven themselves on and off the track, lasting longer and outperforming other bearings on the market. Tech Notes: As with all bearings, please check your tolerances and size before installation. Due to the specialized tools needed, professional install recommended.
