IE450T Big Turbo Kit for MK6 Golf R (Left Hand Drive)

IE 450T DETAILS

As it hit the drawing board, the idea was simple: develop a turbo kit for the MKVI Golf R which not only significantly increases the power output of the vehicle, but also greatly enhances the driving experience. Car enthusiasts, including us here at Integrated Engineering, are often apprehensive when it comes to big turbo upgrades, as larger turbos carry a reputation of increasing turbo lag. We wanted to offer a kit that would increase the power without making the car lose its amazing street-friendly daily drivability. Fast forward through over two years of development… and we are pleased to announce the Integrated Engineering 450T EFR turbo kit for MK6 Golf R.

Detailed Turbo Kit Features

BorgWarner EFR 6758 Turbocharger

Not only developed for reliability, the EFR turbos also offer the highest performance on the market, which is why they have been used on Indy cars since 2012. With extensive testing done on several EFR turbochargers, the 6758 was selected for this kit, as it offered the widest powerband possible with minimal turbo lag. Full boost is achieved around 3300 RPM, making the IE450T kit the fastest spooling on the market, while significantly boosting power output through the higher rpm range.

By employing twin scroll turbo technology, the IE450T EFR kit is the first of its kind on the market, offering both higher horsepower numbers and faster spool time than other available kits. The BorgWarner EFR turbo series offers the latest in turbo technology, using a high-efficiency billet compressor wheel and superior transient response from the titanium turbine wheel, which allows the turbo to re-spool quickly.

The EFR turbo offers OEM reliability with a heavy-duty ceramic ball bearing center section, designed for ultimate longevity. To keep boost control simple, yet effective, the EFR turbo uses a generous 42mm internal wastegate. This wastegate setup works in true twin-scroll fashion, bleeding off pressure from both sides of the turbine housing.

IE Performance Software

In order to create a truly plug-and-play turbo kit, matching software is included to re-calibrate the ECU to suit the added horsepower from the hardware upgrades. With the amount of design and engineering that went into the hardware portion of the kit, we knew it was necessary to take the same amount of care and time developing software developed for the specific kit. Our engineers completely reverse engineered the ECU, which gave them a starting point for developing software that not only supported the additional power, but also made the driving experience much more enjoyable than stock. With the use of our in-house Dynapack DP42 dynamometer, the IE Golf R spent months of its life getting software developed, endurance tested, and drivability perfected.

Along with the support for the power of the EFR turbo, we have incorporated several other features in the software, such as a raised rev limiter, removed speed governor, increased throttle response, and increased operating efficiency. The tune that is offered with the IE450T kit is designed for use with either 91 or 93 octane pump gasoline, with plans to develop an option for 100 octane in the future. With the base IE450T kit, the internals of the block is at a maximum safe power level. Once the 100 octane file is available, we will be offering it to customers with built engines only.

The IE450T software includes the IE Pro features of no-lift shift and launch control. No lift shift allows for upshifting without letting off the throttle. This retains boost pressure during the shift and allows for a fully spooled turbo when you hit the next gear; no re-spooling of the turbo is required. Launch control allows for boost pressure to be built when the car is not moving. This is especially beneficial in drag racing applications, where building boost is critical to get off the line as quickly as possible. Boost pressure is user-adjustable, determined by how far the throttle pedal is depressed; generally, 10-25 PSI can be achieved. Gone are the days of waiting for the turbo to spool after leaving the line. *Launch Control & No-Lift-Shift is currently only available for US Golf R engines at this time.  

IE Cast Stainless Exhaust Manifold

A twin-scroll turbo is only as good as the manifold it is mounted to, which is why we allocated a large number of engineering resources and spent the time to develop and test a true twin-scroll investment cast exhaust manifold. We have designed the exhaust manifold in-house using the latest Computational Fluid Dynamics (CFD) software to optimize flow and balance between all cylinders. We investment cast these in North America from CF8C stainless steel, which not only looks brilliant, but will outlast other manifolds manufactured from lower quality materials.

With longevity in mind, we have designed the exhaust manifold with robust mounting flanges, which will not warp or crack over time. To keep the turbo securely mounted, we also use studs and nuts made from Monel, which is a high-temperature resistant alloy that will not deform and keeps the seal between the turbo and manifold intact. *The IE450T turbo manifold has been designed specifically for use in the IE EFR turbo kit; it will not be sold separately for custom turbo setups.

IE Stainless Downpipe

The included downpipe is made from 3” stainless steel, which is mandrel bent and fabricated to directly fit the application. It incorporates a stainless steel flex section, which allows the engine movement under normal operation. The downpipe has been designed to directly connect to the IE midpipe, which connects directly to the Milltek cat back exhaust, available separately. We use V-band connections, which make for ease of installation, no leaks, and easy adaptation to other manufacturer’s cat back exhaust systems.

IE Cast MAF Housing

To allow the additional airflow past the mass air flow sensor (MAF), we include a cast aluminum MAF housing that fits directly between the turbo inlet pipe and the intake tube. This housing features a fully machined inside diameter, which is absolutely necessary for consistent MAF readings. The MAF diameter is a perfect match for the tune that is provided with the kit, offering OEM drivability. To finish off this beautiful cast piece, we machine the inlet/outlet hose connections and mount bosses, then powder coat it black.

IE Cast Turbo Outlet Pipe

Our kit includes a high flow USA-cast turbo outlet pipe, which is a direct replacement for the factory piece, providing a smooth connection between the turbo and the intercooler. To keep hoses securely attached, the barbs on this unit are fully machined and the factory mount points are utilized to keep the pipe from moving. The cast outlet pipe is finished with a matching black powder coat finish.

Oil & Coolant Lines

The IE450T kit includes oil and coolant plumbing that has been designed specifically for the MK6 Golf R application, with use of mandrel-bent hard lines and heat protection in critical areas. All necessary adapters and flanges are included to make plumbing a simple, plug-and-play task. All included lines are made to replace the factory units entirely, with no cutting and splicing of OEM lines necessary.\

Ancillary Components

To make the fitment of hardware components perfect, specific brackets and adapters have been designed. In order to use the internal wastegate on the EFR turbo, we use a thick-gauge stainless steel actuator bracket, which is designed to eliminate flex and maintain consistent boost control. This component was custom designed to fit within the space constraints on the 2.0T FSI engine. The IE kit is complete with all necessary mounting bolts, nuts, washers, and gaskets required to install the new turbo components. Several custom billet adapters are also included, which are used to plumb PCV system and oil lines to the turbo. A new set of pre-gapped spark plugs are included, which are necessary for the higher boost output of the EFR turbo.

IE Silicone Couplers

To make all connections as smooth and direct as possible, we use custom silicone couplers, which not only get the job done but look stunning as well. All couplers are made from high-quality 4-ply nylon-reinforced silicone, finished with a glossy black color. Larger couplers, such as the turbo inlet pipe, are wire reinforced to provide the rigidity that is necessary. To make each connection secure, we include clamps that are for use specifically on silicone, providing the tension needed without cutting into the coupler.

IE PowerLink Software Delivery

Each IE450T turbo kit includes an IE PowerLink V2 that will enable the end user or dealer to install the software on site using any laptop with a Windows operating system and USB port.  The PowerLink device also allows for switching between different ECU maps (for example, switching between 100 octane or 93 octane files).

One-Year Limited Warranty

All kit components manufactured by Integrated Engineering carry a one-year limited warranty against material and manufacturing defects from the invoice date. IE manufactured components include the turbo manifold, MAF housing, cast outlet elbow, oil and coolant lines, and custom silicone couplers.   Components not manufactured by IE, such as the BorgWarner EFR turbo, are subject to the warranty provided by the 3rd party manufacturer.

Engine Internal Requirements

In base form, the IE450T kit is designed to bolt directly onto a stock Golf R engine without any need for upgrading internal components. However, a 100 octane file will be available for more extreme setups, which do require a built bottom end and upgraded valve springs at the minimum. We have taken this into consideration and offer a Sport Series short block, which is completely machined and assembled, ready to install into the car. We also offer Sport Series cylinder heads, which are also machined and assembled with IE performance components.

IE450T Map Pack

Unlock the highest performance levels from your IE450T kit by adding the IE450T Map Pack. This map pack includes additional octane files for use with 93, 100, or 104 octane fuels along with a valet mode.  You can switch between these maps easily using your IE PowerLINK direct port flash cable included with the kit.  The higher octane allows our engineers more aggressive tuning of the ECU maps providing larger gains on the same hardware.

Suggested Install Time

Installation should be performed by an experienced technician and will take roughly 8-12 hours to complete the process. The process has a few tricky steps that will require a diverse selection of tools and extensions. The entire install process has been written out step-by-step and included as a PDF file on a USB flash drive. The install process can also be viewed ahead of time under the DIY Corner section of our blog. Click here to download Install Guide
