600HP Big Turbo Audi S3 | Part 2 | Eurofed Builds

On this addition of Eurofed builds we check back on the big turbo S3. For this build our client had tasked our performance team with creating the ultimate Audi S3 that is capable of producing at minimum 600HP on pump gas. 

However the challenge was not only in producing the necessary amount of horsepower. This is to be the clients daily driver, that upgraded performance needs to have everyday reliability and drivability with minimum sacrifices. That means taking every aspect of the Audi S3’s power train into account and upgrading where necessary. With that challenge in mind the big turbo kit of choice was the Garret G3-770 Big turbo kit from PAG parts. (see parts list below)

Last time we saw the S3 it was completely disassembled and we went over what parts are necessary for building a 600HP+ Audi S3. Fast forward the S3 has been fully assembled with a fully built 2.0T by our Audi technicians and a base-line tune from EQT was uploaded to allow the motor to be broken in.

Here we discuss the importance of utilizing proper engine break-in procedures when building a high performance engine and the overall fitment of the Garret G3-770 Big turbo kit from PAG parts.

What Does It Mean To Break-in a Built High-Performance Engine? 

When assembling a built performance engine with new forged internals you are essentially building a brand new engine. While the parts are stronger and more reliable than what was originally utilized from the factory, they need time to adjust and settle to use. The internals of an engine, especially one making 600HP, endure a lot of stress from combustion. If a built motor is not properly broken-in it can vastly increase the potential of premature engine failure down the road.

How to break-in a built engine?

The basis of the break-in procedure is driving the vehicle for at least 500 miles and not putting excessive stress on the engine.

  1. Change gear at a low RPM
  2. Do not floor the accelerator
  3. Avoid short trips

How long does the engine break-in procedure take?

Typically it is recommended that the vehicle is to be driven in the manner specified above for about 1000 miles. After the 1000 miles period, an oil change service is performed by a certified automotive technician. The oil from the initial build and break-in process is analyzed.

The condition of the oil will dictate the overall health of the engine and if performance engine break-in procedures had been done. Once the engine is deemed ready for extra load by our certified european performance technicians you can engine your fully built engine and all of its extra horsepower

Fit And Finish Of The Build

Our service advisor Seth noted that no modifications were needed for the overall fitment of the Audi S3 big turbo kit from Pag parts. The assembly process was as easy as putting together a factory engine. The only modifications done for fitment was on the intake to make room for the APR catch can

Driving Impressions Of The Build

While the engine is still currently in the break-in process, that does not allow our team to fully test the performance capabilities of the new set up. However it does present the opportunity of driving the vehicle extensively under low load, such as you would on your normal daily commute. This goes back to creating a high horsepower audi S3 with the everyday drivability and ease of that does not yield any drawbacks. Therefore creating the perfect test for the initial challenge of the build

Up to this point the big turbo Audi S3 operates exactly as you would expect any normal S3. The only indication from the driver’s seat that the vehicle has been extensively modified is the increased exhaust note from the Milltek performance exhaust and a slight vibration under deceleration due to the upgraded Black Forest Industries engine mounts.

How To Build A Big Turbo Audi RS3/TTRS

When Audi debuted the latest iteration of its 5-cylinder turbo-charged all-wheel drive drivetrain, enthusiasts rejoiced! For many audi enthusiasts our love for the brand was sparked by the iconic Audi S1 quattro of the infamous group B rally era. One of it’s most defining characteristics was its 5-cylinder turbo engine that sounded unlike any other performance vehicle produced and quattro all-wheel drive to put the power down. 

However, Audi’s latest 5-cylinder engine, the 07K DAZA EVO has even more performance potential than before. Being Audi enthusiasts ourselves it was only natural for us to gravitate to the platform and see what it could do first hand.

That is how we ended up with our 800WHP Nardo Grey RS3 shop build that we let David Patterson, AKA Thatdudeinblue, review.

From our Nardo Grey RS3 we were able to develop a build process that we can offer to our clients to have their very own 700HP+ RS3/TTRS with no sacrifice of driveability or reliability. 

On this addition of Eurofed builds we showcase the first stage of the process of having your Audi TTRS/RS3 built for high horsepower by us. Here we will go over the recommended parts we utilize and why you would need them for a 700HP+ big turbo 07k build.  

Stage 1: Multi-point vehicle inspection 

Before a single modification is made the RS3/TTRS is inspected by our dealer-trained audi technicians. This is done to make sure the vehicle is up to date on its scheduled maintenance and able to withstand double the horsepower. For us a vehicle is only as good as it has been maintained.

Stage 2: Performance Parts List Assessment 

After the vehicle has been inspected, service and deemed ready for the build process our team of service advisors will discuss your choice of modifications and aftermarket performance parts that will get you to the desired power level 

These are the recommended parts that we suggest utilizing for a high horsepower build. This parts list of from the RS3 build video above. There are other choices of parts from different manufacturers; however we recommend speaking with a Eurofed service advisor to confirm product quality.

DEKA Clutches

  • The factory DQ500 gearbox is designed to handle torque output but only to a certain point. When going for the higher power levels the transmission needs to be able to handle the power as easily as the engine is at producing it. This does include being able to withstand the utter violence that is launching a big turbo Audi RS3.
  • The upgraded DEKA clutches are designed to handle 1000+ horsepower, even from a launch.

IROZ Haldex Controller

  • While the RS3 is advertised with having “quattro all wheel drive” in reality its all-wheel drive system is based on the haldex system used on similar AWD MQB platform cars like the Volkswagen Golf R, Alltrack, AWD A3 and TT/TTS. The Haldex all-wheel drive is a front-drive biased system, meaning a larger percentage of the engine power is delivered to the front wheels than the rear wheels. 
  • What the IROZ haldex controller allows the driver to do is change the torque split between the front and rear wheels. If more power is needed to the rear wheels the driver is able to set it to the exact amount with a scroll-knob discretely installed on the dash.  

BFI Engine mounts

  • Higher horsepower vehicles demand more robust engine mounts and bushings to handle extreme increases in power. The factory Audi TTRS/RS3 engine mounts are designed with a certain amount of durability at the stock horsepower. With more robust engine mounts the vibrations from the engine are kept to a minimum and minimize torque loss. 

ECS Subframe Bushing

034MOTORSPORT BILLET SPHERICAL DOGBONE MOUNT

Unitronic P3 Dash Gauge

  • You can never have a shortage of data when operating an extensively modified big turbo Audi RS3/TTRS. Figures such as Air/fuel mix ratios, Ethanol content, exact boost pressure. With access to that data there is less guess work when it comes to troubleshooting potential issues down the road.

Upgraded Fuel pump

  • With all the added boosted air being pumped into the cylinder from the new big turbo you need the fuel system to match it and provide a sufficient supply of fuel. Given that challenge, we recommend utilizing a flex fuel set-up for ethanol based fuels, every point of the fuel system needs to be upgraded, including the fuel pump.  

APR ignition coils

1000cc Fuel injectors 

  • With the added fuel pressure from the upgraded fuel pump you need the right sized fuel injectors to handle it. 
  • Fun fact about the RS3/TTRS fuel system is that it utilizes two fuel injectors per cylinder, a secondary and a primary. Most factory vehicles only come with one per cylinder. This is one of the secrets why the 2.5T DAZA 07K EVO engine is capable of producing 550 wheel horsepower with just a few bolt-on modifications because of its ability to supply an ample amount of fuel from the factory. However even an overbuilt fuel system such as this has its limits and need to be upgraded if you are in the pursuit of horsepower past stage 2 modifications.

Engine Catch Can

  • When you considerably increase the amount of turbocharger boost being introduced into the engine, in turn it increases engine crankcase pressure. If not regulated the increased crankcase pressure can cause damage to internal engine components. This increase in pressure is known as  “blow by”. An engine catch can is designed to regulate the pressure of the engine and catch the blow by. 

Transmission Catch Can

  • Such as with the engine catch can, the higher demands on the transmission from the increased power introduces more pressure. The transmission catch can is designed to relieve that pressure.

CTS Turbo Intercooler Piping 

  • Running more boost means better airflow management is also necessary to minimize inconsistent boost delivery. The CTS turbo Intercooler piping allows for better airflow management to and from the intercooler and into the intake manifold. 

Forge motorsports Intercooler Couplings

APR Turbo Inlet Pipe

Iroz Motorsports Billet Front Mount Intercooler

  • To top off air flow management an upgraded intercooler is critical. The stock factory placement Audi RS3 intercooler can only handle so much airflow. Once the boost pressure is beyond a certain point the factory intercooler becomes a choking point in the system and will drastically reduce boost pressure. With an upgraded front mount intercooler, such as the Iroz unit, it can allow for more consistent air flow and drastically reduced air intake temperature. 

Race3 Crash Bar

  • In order to make room for the front mounted intercooler the factory front impact bar is replaced with a unit such as the Race3 Crash bar. This creates the room necessary for an upgraded intercooler and will still keep the driver safe in the event of a collision. 

TTE-777 Turbo

Integrated Engineering Forged Rods & Piston

  • When approaching supercar levels of performance the internals of the engine must be strengthened to handle extra boost and limit the chance of internal failure. 

Stage 3: Drivetrain removal & disassembly 

When the vehicle as been deemed ready for building and the parts list is compiled and ordered the disassembly of the drivetrain begins. However before everything is re-installed with the performance aftermarket upgrades stated above, the engine must be blue-printed and properly reinstalled

Stay tuned for Part 2 of the big turbo Audi RS3 build pr where we go over the blueprinting and building of the engine!

AMS Alpha 12 Twin-Turbo Audi R8

AMS Performance has always been the go-to vendor for high-performance packages. With years of experience in the automotive performance field they have developed packages which include upgraded turbos, intercoolers and supporting modifications of the highest quality. 

Their latest offering is the Audi R8 Alpha 12 twin turbo package combined with MoTeC ECU’s. The Alpha 12 kit was developed to provide 1250+ horsepower on the Audi R8/ Lamborghini Huracan platform with OEM levels of reliability and turn-key ease of use. So naturally it was the only logical choice for Eurofed to be an authorized AMS performance dealer and utilize the kit for the twin-turbo program. 

When doubling the horsepower of an Audi R8 there is no room for error given the cost of the platform itself and the twin-turbo kit. And the Audi R8 has always been known as the everyday supercar, which means there can not be a substantial take away from that ease of use. With the robust and thorough design of the AMS Alpha 12 package combined with the technical expertise at Eurofed for installation, it creates the absolute pinnacle of reliable Audi R8 performance.

What Does The Eurofed Twin Turbo Program Entail?

The Audi R8 twin-turbo program begins with having the vehicle brought into our Eurofed performance facility and inspected by one of our certified technicians. The technician inspects for maintenance items that need to be serviced and points of concern on the condition of the vehicle. 

Once the vehicle has been deemed ready for install, the full disassembly of the vehicle is begun. At that point the vehicle is then rebuilt and outfitted with the AMS alpha 12 twin turbo kit. Next the vehicle and it’s MoTeC ecu is dyno-tuned to the clients specified fuel maps. At the end the vehicle is given a final multi-point inspection to ensure it is ready for the client to enjoy worry-free.

This whole process takes on average 2-3 weeks time from when the vehicle is inspected by a dealer certified technician.

  • Optional Race Track Mappings and/or Additional Mappings Available Upon Special Request

The Benefits Of Using A MoTeC ECU

The secret behind the Alpha 12 package’s success is the utilization of a MoTeC ECU. The MoTeC ECU is an aftermarket performance stand-alone engine management solution that allows a tuner a higher degree of tunability and system monitoring. 

Traditionally when tuning a vehicle with the factory ECU, even when fully unlocked, there is a limited amount of access a tuner has to calibrate systems when going beyond a certain performance limit. The MoTeC M124 Kit is a complete replacement for the two factory ECUs, utilizing existing wiring, sensors and mounting hardware to deliver plug-in convenience with fully programmable control. 

Along with fuel, ignition and camshaft control, this kit also supports other OE ECU features such as cruise control, A/C, adjustable driving modes, and all OE dash functionality and warning lights. The only difference is the system is designed to manage a vehicle that produces 4-digit horsepower numbers. 

In addition to these OE system integrations, the MoTeC M142 EMS allows us to include advanced motorsport features that can improve traction and acceleration, boost control, and even transmission shifting. The advanced launch control and traction control features allow our calibrators to configure acceleration characteristics at a true motorsports level. We also have the ability to utilize MoTeC’s Level 3 internal data logging feature, which allows for laptop-less logging of over 900 parameters that can be used for monitoring, diagnosis, and improving the performance of the vehicle via testing.

The MoTeC M124 kit allows the AMS alpha 12 package to function as intended and provide hypercar levels of performance while maintaining the ease of use you’d expect from a factory Audi R8

Where Can I Have An AMS Performance Twin-Turbo Kit Installed On My R8/Huracan?

At Eurofed we are an authorized AMS performance dealer and proud to have built one of the first Audi R8’s with the Alpha 12 AMS package installed. With the most experienced automotive technicians in the field, we make sure the installation is done properly the first time to ensure reliability.

600HP Big Turbo 2.0T Audi S3 PT: 1 | Eurofed Builds

On this addition of Eurofed Builds we begin the process of equipping an Audi S3 with the Garret G3-770 big turbo kit from PAG parts along with a fully built 2.0T EA888. The idea behind this build is to maximize the performance capabilities of the 2.0t EA88 engine, DSG dual clutch transmission and quattro all-wheel drive system. This ultimately leads to a power level goal of 600HP for the build. However this big turbo Audi S3 isn’t going to be a dedicated track car. It will be our client’s daily driver! 

That means every point of the powertrain is taken into account and upgraded if possible to ensure everyday reliability. With all of the necessary supporting mods this Audi S3 will be capable of as much as 700HP but for reliability will be tuned to a more sensible 600hp.

Big Turbo S3 Parts and Supporting Modifications

What Has Been Done So Far Now?

Thus far the 2.0T engine has been fully disassembled by our Audi technician to make room for the new upgraded components. Prior to the engine build this Audi S3 was equipped with APR intake, APR intercooler, APR lowering springs, APR rear sway bar and a Milltek Exhaust  

Next Stage of the Build 

The next stage of the build begins with the reassembly of the built 2.0T with forged internals and the necessary supporting mods listed above. Furthermore the dual-clutch transmission will be outfitted with the upgraded SSP clutches to handle the power from the 600hp S3 2.0t.

When the engine reassembly stage is complete the vehicle will be provided with a custom tune made for the specific modifications. The tune will maximize the performance potential and provide the reliable 600hp figure.

B8 S4 Avant Build PT: 2 | Eurofed Builds

On this addition of Eurofed Builds we catch up with the progress that has been made on the Audi A4 Avant that is having a supercharged 3.0T engine and dual clutch drivetrain swapped in. Last we checked the 3.0t was removed from the S4 Sedan donor and being prepped for its new home. That prep included replacing all gaskets, sealants, and timing chains to make sure all needed preventative maintenance is done. 

The idea behind this build is to take our client’s 2.0t powered Audi A4 Quattro Avant and swap in the supercharged 3.0L V6 drivetrain from a S4 Sedan. Thus essentially turning this A4 into the B8 S4 Avant that wasn’t sold to us in the United states. Along with the addition of performance upgrades to maximize the performance potential of the 3.0t platform reliably.

What Has Been Done So Far Now?

Thus far the 2.0t has been removed from the A4 Avant and set aside. In its place, the 3.0t engine along with the dual clutch transmission, rear differential and suspension has been physically installed into the A4 Avant chassis. 

No modifications were needed to be done to the A4 Avant chassis in order to fit the S4 drivetrain and suspension. The B8 chassis was designed with the intention of having multiple powerplant options and manufacturing as cost effective as possible to allow for all to fit easily to the same chassis. However that concludes the “easy” part of the swap. Next up begins the tedious process on wiring and programming!

Next Stage of the Build 

The next stage of the build is beginning the process of connecting and adapting the 3.0t engine wire harness & ECU to the Avant chassis in a manner that will allow them to operate harmoniously. On top of that the S4 Avant will be outfitted with Bilstein B16 Coilovers to bring the suspension up to par with the performance we expect the engine to put out. When the wiring is sound and the suspension is sorted, the S4 will be outfitted with a custom Eurofed Tune to maximize the increased boost generated by the S4 CTS turbo supercharger pulleys

B8 S4 Avant Build PT: 1

On this edition of Eurofed Builds we begin the process of creating a dream Audi build for one of our clients. Here in the states we weren’t as blessed with the choices of fast Audi wagons like our friends have had overseas for years. For us they are a forbidden fruit that we can only dream of owning. And such was the story for our client and his A4 Avant!

The idea behind this build is to take his 2.0t powered Audi A4 Quattro Avant and swap in the supercharged 3.0L V6 drivetrain from a S4 Sedan. Thus essentially turning this A4 into the B8 S4 Avant that wasn’t sold to us in the United states. Along with the addition of performance upgrades to maximize the performance potential of the 3.0t platform reliably.

What Has Been Done So Far?

Thus far the 3.0t and entirety of the drivetrain has been removed from the S4 sedan donor vehicle and being prepped for re-installation into the avant. While the 3.0T was out of the vehicle our certified Audi technician has replaced all normal wear maintenance items. This includes all new oil seals/gaskets and performing a timing chain service.

This is done to make sure the engine is in the best running condition and fully refreshed for its new home in the Avant. After the engine was given a full refresh it was now to be outfitted with performance modifications. Performance upgrades include B8/B8.5 S4 CTS turbo supercharger pullies to allow the supercharger to make more boost and a custom Eurofed Stage 2 tune to turn the extra boost into increased horsepower. 

Next stage of the Build 

The next stage of the build is mating the now fully refreshed Audi S4 3.0t and dual-clutch transmission to the A4 Avant. Finalizing the physical 3.0T swap on this A4 Avant. Once it has been fully installed begins the tedious process of installing the wiring harness and making it function with the Avant shell. On top of that the rear subframe and suspension from the S4 Avant will be swapped in along with a set of Bilstein coil overs.

Make sure to stay tuned for future installments of this epic B8 S4 Avant build process. You can also keep with our video series of this S4 Avant and other Eurofed builds on the Eurofed YouTube channel!
