E46 M3 S54 Stock Rebuild

The high quality parts and rebuilding techniques we offer in our performance engines are also used in our stock rebuilds. All parts are meticulously cleaned and inspected, the block is bored and precision honed with a torque plate for more exact cylinder roundness, and pistons, bearings, oil pump, seals, etc. are replaced with OE parts. A careful hand assembly and blueprinting gives you an engine we expect to outlast the original, and at a substantial savings over a factory exchange engine. Bearings, cam gear bolts and other parts updated during production by BMW are incorporated into our S54 rebuilds.

E46 Carbon fiber engine covers  


Dress up your engine bay or replace the cracked, original plastic factory engine covers with our carbon fiber engine cover P/N 11121E46   




E46 oil pan baffle for M52tu and M54

The M52tu / M54 Oil Pan Baffle is a crucial upgrade for a tracked vehicle. This baffle is designed to keep oil surrounding the pick-up at all times. Under hard cornering and acceleration loads this baffle keeps your BMW engine alive. It is inexpensive insurance against costly engine repairs caused by oil starvation. It is easy to install, but does require some welding. Fits E46 BMW’s with M52tu and M54 engines. It does not fit Xi Models. P/N 1113E46


EMP Stewart Water Pump

Fits M50, M52, M54 in the E46.  Flows 15-20% more than stock. Stainless steel impeller with silicone carbide and sintered carbon graphite internal seal. Includes o-ring seal.  P/N 11511E36E46



Sprint Booster  

Sprint Booster makes your car's throttle respond faster to your foot. As a result, your gas pedal actually achieves a full throttle response 25% sooner than the stock configuration. Even if you have a 'sport' button, Sprint Booster will quicken the throttle response time. It doesn't matter if you have a Sport Mode, ECU software, or 'Chip' on your car, Sprint Booster works independently of other modifications. It simply makes the throttle more sensitive, making the car 'feel' faster. Sprint Booster installs in minutes, and is easily removable. Plug-n-Play performance!

BMW E46 Brembo GT Big Brake Kits

Brembo is the worldwide leader in the engineering, development and production of braking systems and components for automobiles, motorcycles and commercial vehicles in the Original Equipment, Aftermarket, Racing and High Performance market segments.

The Gran Turismo system’s level of technology and performance is unrivaled by any other product on the market.  By utilizing larger calipers and discs, thermal capacity and brake torque are increased.  

  • Brembo Calipers have 4, 6 or 8 sequentially sized pistons and are available in black, red or silver.

  • Brembo 2-piece ‘floating’ hat and rotor assemblies reduce unsprung and rotating weight and dissipate heat faster.

  • Brembo drilled or slotted 2-piece rotors are up to 16” dia. (405mm).

  • DOT and TUV certified Goodridge braided stainless steel lines are guaranteed for life.

  • Brembo high performance brake pads.

  • Brembo ‘floating’ anti-rattle rotor hardware.

  • Brembo billet aluminum brackets with aircraft quality hardware.

Brembo GT Kits work with the stock master cylinder and it doesn’t affect the ABS or any traction control systems.  The 6-Piston Monobloc Calipers come in several different piston bores based on the application.  These calipers are the stiffest cast caliper Brembo has made and they come in Black, Red or Silver.  High Performance Brake Pads included with the kit are suited for high end street use as well as limited track application.  Brembo engineering produces Zero-Off-Pedal Drag on rotors from pads.  The Billet Aluminum Bells with Brembo “Float” bushings allow the disc to seek its true centerline for consistent braking performance.  Floating Disc design reduces heat and stress transfer to wheel bearings and hubs.  The 2-Pc Rotor Assemblies also reduce the un-sprung weight (approximately 8 pounds per corner) for better handling, quicker response and better acceleration.    

Each Kit Includes:

  • Cross Drilled or Slotted Brembo Vented Racing Discs

  • Lightweight Billet Aluminum Bells With McLaren “Anti-Rattle” Springs

  • Aluminum Monobloc Calipers With Six Sequentially Sized Aluminum Pistons

  • High Performance Brake Pads

  • DOT/TUV Approved Stainless Steel Braided Brake Lines

  • Aircraft Quality Mounting Brackets And Hardware

  • Easy To Follow Installation Guide

Slotted Brake Rotors

While nothing beats the appearance of the cross drilled brake rotors, we suggest using the gas slotted versions for true high performance and track use due to its superior wear rates and brake cooling. Our gas slotted brake rotors have the gas slots milled to the wear limit for easy visual checks of brake rotor wear.

Korman High Performance Brake Pads

For high performance and heavy duty street conditions the Korman high performance compound remains a top performer in the realm of street/performance brake pads. With a compound giving a friction level up to .41, this is an amazingly fast stopping brake pad. These brake pads will give you an impressive increase in stopping ability with very minimum amount of pedal effort. Perfect for prolonged everyday street driving while also being capable of enduring the most severe use without fade. These brake pads are also very rotor friendly and have absolutely the lowest noise and dust levels possible, far below O.E.M. equipment or any other high performance brake material. Superb stopping power under heavy use. Great for occasional auto crossing, solo events, off road events and rallies. Perhaps one of the overall best performing, clean and quiet everyday high performance driving brake pads ever made.

Korman Racing Brake Pads

Being able to maintain an average of a .50 friction level within a very wide temperature range gives the Korman Carbon Kevlar racing brake pad astounding versatility and makes it very suitable for a wide array of various track conditions. With use of the latest ceramic technology, the Carbon based semi-metallic materials allow the pads to absorb tremendous amounts of heat and dissipate it at a very even rate, while at the same time insulating excessive heat from calipers. Another

inherent characteristic of our Carbon Kevlar material is how quickly the pads warm up to race temperature which is quite helpful during restarts, and when track time is limited. Optimum operating temperatures are 450ºF and above. When used with cast iron and steel alloy brake rotors, this compound requires a minimal bed-in period. Throughout the entire heat range, the Carbon Kevlar material will give extremely consistent modulation and predictability along with smooth release characteristics up to the threshold. Another benefit of our compound is that even with the high friction levels and broad temperature ranges, the unique properties of our compound allows the rotors life to be extended to the maximum. This is one of the most rotor friendly racing brake pad material ever built.

 NOTE: Manufacturer/Distributor assumes no liability for use of this product. Brake Pads are for racing only.

Ceramic Thermal Barrier Coating

From Aerospace technology comes this oven baked metallic/ceramic finish that is far superior to ordinary header paints. In salt spray testing where high temperature paints lasted 40-50 hours, the ceramic coating lasted over 5,000 hours. The ceramic thermal barrier finish also coats the inside of the pipe. The thermal barrier will reduce under hood temperatures and testing has shown horsepower gains due to combustion chamber stabilization and increased gas velocity. A great option for show room stock racers who are not allowed headers. Available in as cast grey for that “stock” look or in silver or black.
