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.

The Profi II ASM is designed to be used as a four-point system. For this reason it is perfect for use in Driver Education cars or any other application where stock seats are retained. A seat that was not originally designed for use with a racing restraint should never be modified to accept a sub strap. The Profi II ASM incorporates Schroth's legendary ASM (Anti-SubMarining) technology that is the only thing like it on the market. ASM is an extra fold of material sewn into the right shoulder belt that elongates at a different rate than the outboard belt. This allows your upper torso to twist slightly. On the rebound phase, your torso is planted firmly back in the seat rather than allowed to slide under the lap belt. The Profi II ASM shoulder is only available in 3" width but is still suitable for use with a Forward Neck Restraint such as a HANS device You can add a dual sub strap to make this belt into a 6 point at any time. Schroth has recently tested this harness with a HANS device, and the results were great. So you can in fact use this harness with a HANS device. Another feature unique to the Profi Series 2" lap belts is the "Flexi Belt". The End Fittings and Cam Latches are wrapped into the harness, making it so that the lap belt can be changed from a Pull-Up configuration to a Pull-Down. This allows you to set the belt up just the way you want it for your specific situation. It also allows for Bolt In brackets to be wrapped in for the lap belts if needed. Snap-in brackets come standard on the laps. The Shoulders come ready to wrap around a roll bar. Snap-in or Bolt-in attachments can be bought separately. The Lap Belts come with Snap-in Attachments. Bolt-in brackets can be wrapped in if necessary.

With many motorsports teams and race enthusiasts now pushing over 1000 horsepower, the B58 is seeing oil temperatures well above normal. Once oil temperatures pass a safe limit, the G2X/G42 will go into limp mode. Needless to say, this can ruin a race, track session, or your overall driving fun in general.

The 3.0 Liter B58.2 turbo engine of the specified BMW/Toyota models is equipped with an indirect charge-air cooling circuit. So the cooling of the charged air is realized by a watercooled intercooler, which is integrated directly into the intake manifold. The WAGNERTUNING intake manifold with integrated intercooler has got a new performance core which was specially developed for the high requirements and individual mounting position of the B58.2 engine and offers 128% more external core volume compared to the original intercooler. The calculated ratio between the inner and outer cooling surface generates a maximum heat transfer and at the same time the best possible internal airflow. With the help of CFD simulations, the CNC-milled end tanks were designed for optimal airflow conditions. The result is an excellent cooling property with minimal back pressure. That`s why this kit is also perfect for racing use. An optimal cooling effect of the charged air with a significant increase in performance! All WAGNERTUNING radiators are equipped with a heat-conductive anti-corrosion coating to ensure a lasting cooling effect. The plug & play installation of the system is simple and easy to perform (an installation instruction is included as well). Advantages of this product: significantly better cooling performance (up to 20°C cooler IAT) maximum mechanical discharge of the turbocharger (35% less back pressure) more power and torque for your engine 100% pressure resistance 100% Plug and Play (no modifications) preprocessed port fuel injection (Fuel Rail not included) three 1/8 NPT ports for measuring additional parameters six preprocessed NOS or WMI ports (Nozzles not included) this intake manifold is suitable for all performance levels up to 4 years warranty important information for oil service: the oil filter still can be replaced without removing the intake manifold again!

There are many benefits to installing harnesses in your BMW -

  • maintain a proper driving position
  • keep you planted in the seat and not bracing with your left leg or shoulder
  • lower lap times thanks to improved driver confidence
  • advanced technology is safer than standard 3-point belts

It's hard to put into words just how effective harnesses are in improving your driving experience. In addition to the obvious safety benefits, harnesses make you a better driver by removing distractions so your hands and feet are used for car control instead of bracing against a door panel or dead pedal. Everyone with harnesses will agree: they are a must-have upgrade to your driving experience and they wish they had installed them sooner.

The Rallye harnesses are Schroth's universal fit, bolt-in harness design that still meets DOT and TUV specs. The Rallye 4 harness fits most BMWs better than a Rallye 3 type thanks to its four mounting points that bolt to four existing anchor points in the BMW chassis: outboard lap belt anchor on B-pillar, inboard lap belt anchor on seat, and both rear seat belt anchors. The Rallye harnesses are a fixed, semi-permanent install but a quick-connect buckle is included in the rear seat harness so that the front and rear sections can be separated and tucked away when not in use. This also allows you to use the stock 3-point seatbelts in the front and rear seats without obstruction. All Schroth harnesses feature their asm technology that prevents your body from sliding under the lap belt and redces head and chest deceleration forces. Rallye belts are not side-specific; they fit either the Left or Right side of the vehicle.

Optional: Schroth Grips. Schroth harness grips slide into the ends of your Schroth harnesses and give your fingers something to lock onto when tightening the harness. Otherwise, your hand - or glove - has to yank on the end of the strap which might be slippery. Sold per harness for both shoulder and both lap belts (4 Grips total).

Seat Compatability: Schroth approves this harness only for stock seats or seats that have passed independent crash testing. The seat design must have a separate headrest and backrest. Single piece headrest and backrest (e.g. - F8X M3/M4 seats, Porsche 911 seats) are not approved because the shoulder straps fall to the sides and will not secure the driver properly. Observe all guidelines and instructions for installation and fitment.

E36 Fitment Note: a special bolt is required for installation on the stock E36 seat. Make sure you order this bolt for any E36 installations. Click here for the link to the bolt.

Rallye 4 Harness Summary:

  • Suggested Use:  autocross, daily driver
  • Shoulder Belt:  2" pull down
  • Lap Belt:  2" pull down
  • Buckle:  Rallye push button
  • Installation:  permanent bolt-in
  • Seat Compatability:  approved only for stock seats with headrest separated from backrest
  • HANS compatible?  No.

 

When using any racing harness in any environment - even normal street use - adhere to this advice: "all the way tight, all of the time". Never loosen or slacken the belts for comfort or convenience! A loose racing harness will not protect you.

The JB4 is the most advanced and highly featured tuning system available for your B58 vehicle. Power gains are up to 60hp to the wheels (80hp crank) on a completely stock car on pump gas for a B58; gains with bolt on parts, higher octane, and larger turbos are even higher. The JB4 features a simple plug and play installation harness for easy installation & removal and includes many features not found with any other tune. Including on the fly in dash map switching between factory and various performance maps, optional in dash gauge displays for boost, boost limiting by gear for improved traction in lower gears, progressive water/methanol support, built in data logging, built in code reading, optional direct EWG control to prevent throttle closure with exhaust modifications, exhaust flapper control, and much more. Other more expensive tuners may claim to equal the JB4's technology but upon closer examination lack most if not all of the JB4's features. Remember the JB4 does not require any additional modifications or previous stages. Simply install the JB4 as your first and only modification and enjoy an entirely new fast and smooth racing experience. The JB4 also does not require any user setup or customization but for those who are interested in logging, adding new features as we post them, etc, we suggest the BMS DATA cable or REV3 mobile phone adapter. FEATURES AND BENEFITS Power gains of up to 50hp to the wheels on a stock vehicle Quick Plug & Play Installation CANbus integration offering unrivaled tuning features and performance Runs as smoothly as stock, this is how your BMW should have come from the factory Compatible with all driving modes Fuel economy unchanged during normal driving Compatible with JB4 Mobile for smartphone logging, tuning changes, and adjustment Ethanol (E85) compatible tuning maps Able to read/delete fault codes Not VIN locked, can be removed without a trace and resold down the road Made in the USA Free USA Shipping 5 year warranty Wirelessly connect the JB4 to your Bluetooth 4.0 compatible iOS and Android device via the JB4 Mobile connect kit, or to your Windows laptop with the BMS data cable. Both options allow you to record and analyze vehicle and tuning data, change JB4 performance maps, and update JB4 firmware as we release free newer versions with updates, more powerful maps, and new features under development. Separate JB4 Mobile app purchase also required. Note for 2018+ G chassis vehicles with the digital dash layout, Burger Motorsports have not yet added in the JB4 commands to allow in-dash control but will provide those via a free firmware update once developed. Until then a JB4 mobile adapter or BMS data cable is required for any map and setting changes.
