FCH - Performance Center

Foreign Cars of Hunterdon has a number of performance mods and upgrades for your BMW . With factory trained BMW technicians on staff in our shop, we can help you modify or upgrade  your BMW 328xi, 335i, 335Xi, 535xi, X1, X3, X5, M3 or M5. Whether you want to upgrade your intake, exhaust or go FBO (full-bolt-on), we can install a wide range of modifications on your BMW in our speed shop.

Our favorite BMW to mod is the E90 or F30 335i: 

Starting with model year 2007, BMW introduced the N54 engine. A robust 3.0L twin turbo powerplant with a reported 300 horsepower. Although the N54 had some early HPFP issues, it proved to be an awesome platform for modification and won the International Engine of the Year and Ward's 10-Best Engine awards. The N54 also became a favorite among the Tuner community. Simple tunes saw amazing 100 horsepower increases with increased boost and improved fuel/timing curves. To date, a google search reports the N54 world record is a whopping 861hp! We can install a wide-range of mods on your BMW 335i, whether you bought your N54 from us or just want to upgrade your car for some increased hp.

Here's a list of our top 10 N54 Mods:

1. CARBON BLAST - If you haven't had your valves cleaned, this is the first step to making your N54 run the way it was designed. Improves fuel economy and helps unlock your N54's true potential. A must for any N54 that hasn't been blasted recently.

2. OIL CATCH CAN - If your N54 has been Carbon Blasted recently, a catch can will reduce future build-up and keep your car running strong. We sell and install the Burger Tuning Catch Can. The Burger Tuning OCC is a clean, well made billet aluminum OCC that works.

3. TUNE - There's a variety of tune options on the market for your N54. Stay with the name brands on this one, no eBay tunes allowed. We recommend and install a couple of different options here at FCH. Option one; The JB4 from Burger Tuning. Option two; Dinan. They both have their advantages and disadvantages, it just depends on your wants and needs. Want flexibility and future expansion? We recommend the JB4 with a back-end flash that we can perform in-house.

4. DOWNPIPE - The next step in building real power with your N54 is a downpipe. They come in a variety of types. Both catted and catless options are available. We do not sell catless downpipes and we will only install downpipes on vehicles used for off-road racing applications.

5. CHARGEPIPE - The stock chargepipe on your N54 is weak where it connects to the throttle body. The joint can separate and cause a massive boost leak. Bad news at the race track. We offer chargepipes from VRSF and others with meth bungs and optional BOV flanges. In the event that you decide to run a meth setup in the future, these pipes give you the option.

6. INTAKE - There are more options for intakes than we can list. We will install most intakes whether you buy from us or just want us to install one that you bought somewhere else. Some of our favorites include Burgers DCI, The carbon fiber Dinan intake and even the simple drop-in K&N filter.

7. EXHAUST - Like intakes, the market is full of options for exhaust upgrades designed for the BMW 335i/Xi. Our factory trained BMW technicians will install most well known exhaust systems in our shop but Dinan is our recommendation here. They sound awesome, have little to no drone on the highway and scream at WOT! What more could you want?

8. FMIC - The stock Front Mount InterCooler on your 335i is too small to handle all the awesome power you're producing now. The N54 is notorious for heat-soak under load and sees a significant power drop as IAT's start to rise. Your turbos pressurize the air headed into your engine and the result is increased temperatures in your intake air temps. Even a stock N54 will see improvements after extended pulls on the street or at the track. Our factory trained Technicians can install most FMIC's on the market but we sell and recommend the Dinan FMIC.

9. LPFP - If you've already done any of the above mods we recommend upgrading your Low Pressure Fuel Pump. As your power increases, so does your engines demand for fuel. An upgrade LPFP can also increase your ability to run a higher mixture of E85. Most N54's do well running mixes of E20-E40 but higher mixtures require upgraded LPFP's. Dinan and Fuel-It make excellent options for upgraded LPFP's.

10. METH - Water/Methanol injection WMI is a common upgrade today in turbocharged and supercharged applications. Water/Meth injection helps lower the Intake Air Temps. This makes for more power. The Burger Tuning Meth kit with FSB controller makes it an easy choice for those who fun a JB4. 

 In 2010 BMW started switching the E90 335i/Xi's over to the N55 motor. While still keeping a 3.0L displacement and a posted 300hp, the N55 is very different from the N54. The biggest difference being that the N55 has a single twin-scroll turbo vs. the true twin turbo N54. BMW termed the N55 a twin-power turbo but the reality is that it is a single turbo with a twin-scroll compressor wheel. This single turbo setup makes it tougher to produce N54 gains without a turbo upgrade. The good news is there's a number of great turbo upgrades out there and we can install them for you in our speed shop using our BMW factory trained Technicians. Due to the design of the N55 a Catch Can is not as necessary and will not be on our list of top 10 N55 mods. 

Here Our Top 10 List of N55 Mods:

1. TUNE - There's a variety of tune options on the market for your N54. Stay with the name brands on this one, no eBay tunes allowed. We recommend and install a couple of different options here at FCH. Option one; The JB4 from Burger Tuning. Option two; Dinan. They both have their advantages and disadvantages, it just depends on your wants and needs. Want flexibility and future expansion? We recommend the JB4 with a back-end flash that we can perform in-house.

2. DOWNPIPE - The next step in building real power with your N55 is a downpipe. They come in a variety of types. Both catted and catless options are available. We do not sell catless downpipe and we will only install downpipes on vehicles used for off-road racing applications.

3. INTAKE - There are more options for intakes than we can list. We will install most intakes whether you buy from us or just want us to install one that you bought somewhere else. Some of our favorites include Burgers N55 Intake, The carbon fiber Dinan intake and even the simple drop-in K&N filter.

4. CHARGEPIPE - The stock chargepipe on your N55 is weak where it connects to the throttle body. The joint can separate and cause a massive boost leak. Bad news at the race track. We offer chargepipes from VRSF and others with meth bungs. In the event that you decide to run a meth setup in the future, these pipes give you the option.

5. EXHAUST - Like intakes, the market is full of options for exhaust upgrades designed for the BMW 335i/Xi. Our factory trained BMW technicians will install most well known exhaust systems in our shop but Dinan is our recommendation here. They sound awesome, have little to no drone on the highway and scream at WOT! What more could you want?

The N55 is notorious for heat-soak under load and sees a significant power drop as IAT's start to rise. Your turbos pressurize the air headed into your engine and the result is increased intake air temps. Even a stock N55 will see improvements after extended pulls on the street or at the track. Our factory trained Technicians can install most FMIC's on the market but we sell and recommend the Dinan FMIC.

7. Turbo - The factory turbo on the N55 is a Borg Warner B03 twinscroll. This turbo can make more HP with the above mods but starts to show its weakness in the upper RPM's. Significant drop-off in boost can been seen on the dyno in the upper RPM range. That's where a larger turbo comes in handy. Our BMW factory trained Technicians can install an upgraded turbo on your N55, allowing you to turn up the boost. Pure Turbos makes one of the best options for upgrade with their Stage 1. They offer a Stage 2 turbo upgrade as well but cost and labor increase considerably. Stage 1 holds much higher boost levels in the upper RPM's and has shown up to 70 more horsepower up top. Dinan also makes a big turbo upgrade as well as RB Turbos. Unless you're building a racecar or you want to go BIG the Pure Stage 1 turbo is our recommendation.

8. LPFP - If you've already done any of the above mods we recommend upgrading your Low Pressure Fuel Pump. As your power increases, so does your engines demand for fuel. An upgrade LPFP can also increase your ability to run a higher mixture of E85. Most N55's do well running mixes of E20-E40 but higher mixtures require upgraded LPFP's. Dinan and Fuel-It make excellent options for upgraded LPFP's.

9. METH - Water/Methanol injection WMI is a common upgrade today in turbocharged and supercharged applications. Water/Meth injection helps lower the Intake Air Temps. This makes for more power. The Burger Tuning Meth kit with FSB controller makes it an easy choice for those who run a JB4.

10. SPARK PLUGS - If you've decided to do most of the above mods we recommend changing your spark plugs to the one step colder NGK 95770's. You need to manually gap these to a narrow 0.022". We've seen improved power and reduced misfire issues as you start increasing the power in your N55.

Now that you have your E90 335i making some real power, let's talk about cosmetic, brake and suspension upgrades. We can install a variety of suspension upgrades from coilovers to sway-bars and strut braces. Let's not forget your brakes either. On the track, your car is only as fast as your brakes. Our BMW factory trained Technicians can upgrade your brakes, from complete Big Brake Kits to cross-drilled rotor and pad upgrades. Our Technicians can do the job right. Here's a list of some of our favorite chassis upgrades.

Top 10 BMW Chassis and Cosmetic Upgrades:

1. Stainless Steel Brake Lines - Whether you upgrade your brakes or stick with your factory setup, SS lines will improve pedal feel without costing you an arm and a leg. Your factory brake lines are made up of polymeric inner lining covered in thick rubber. As a result they expand under the extreme pressures found in your hydraulic brake system when under load. SS brake lines have a teflon inner lining covered in braided stainless steel. SS  Lines expand less and maintain a firmer pedal feel under heavy braking. You'll notice more difference in older vehicles like your awesome E90.

2. Performance Rotors - Cross-drilled rotors help dissipate the heat during heavy braking and racing conditions. Once again, the great news here is that we have an abundance of options from multiple manufacturers to upgrade our rotors. In most cases you can find excellent upgrade options for less than the BMW OEM ones. Stop-Tech makes some really nice options for our E90's and we can install them for you as well.

3. Swaybars - One of the most noticeable upgrades, with regards to improved turn-in that you can make to your cars suspension is a larger or stiffer set of swaybars. Depending on whether or not you have the Sport Package suspension, your E90 suspension may already be in a good place but you can always get improved turn-in with upgraded sway bars.

4. Lowering Springs - Springs can drop your vehicle along with its center of gravity. A lower center of gravity will improve your cars handling in the turns and make your vehicle  look more aggressive as well. We can install sport springs from H&R, Dinan, Eibach and more. The key to a good install is a proper alignment after installation. Our Technicians can help with that as well. We have a Hunter Hawk-Eye 4-wheel alignment computer.

5. Sport Shocks & Struts - There's no doubt that upgraded struts and shocks will improve the handling of your BMW E90. The biggest decision here is, which ones. You can choose from stock calibration all the way to race coil-overs. If your E90 struts and shocks are original, it's time to have them checked and most likely upgraded anyway. We have factory trained Technicians on staff to install your suspension upgrades. Our recommendation here are coil-overs from KW.

6. Strut Tower Brace - The chassis on the E90 is already pretty rigid and not known for a lot of chassis flex but a strut tower brace ties the two front strut towers together improving handling. Tons of options on the market for these. Prices range from as low as $150 to over $1,000 for pretty carbon fiber strut tower braces. Regardless of what you want to spend, they all do the same job and we can help with install.

7. Rims - Where do we start? With so many manufacturers and styles this one comes down to budget and personal preference. Dinan makes some really beautiful options for your E90. We have access to all Dinan products including rims. Give us a call for pricing and availability.

8. Exhaust Tips - If you decide to skip the exhaust system upgrade or you don't like the tips that came with your setup, you have plenty of options. The Burger Tuning slip-on tips are easy to install and look awesome. They come in gloss black, chrome and burnt blue. At $99.00 per pair, they won't break the bank either.

9. Rear Deck Spoiler - This is another mod that has a wide variety of options. From body colored M3 style spoilers to clean carbon fiber options. We have access to a number of nice options and can install them for you as well.

10. Black Kidney Grills - This is a very simple mod but it can make a big statement when you black out your kidney grills. The look is considerably more aggressive and just adds a nice, sporty touch to you Bimmer.

These lists are just our opinion and in some cases we may recommend a different order but overall these are our favorites.
