BMW M2 G87 engine preparation: Towards 1000 horsepower!
Hello and welcome to another article on the engine and chassis preparation of our BMW M2 G87, which we've had for a year and a half now. We're going to look in detail at the M2 G87 preparation project, which aims to achieve an impressive 1,000 bhp. Let's get technical.
The project to prepare the M2 G87 was an ambitious one. The main objective was to increase power and improve the vehicle's overall performance. With a multitude of modifications made, we worked on various aspects of the engine, chassis and braking systems to achieve our goal, because let's face it, when you're aiming for 1,000 bhp, you need it to brake at the next bend.

Mechanical Modifications
Let's start with the mechanical modifications made to the engine. We had a TTE 950 stage 3 turbo installed. As you're beginning to know, we didn't stop there. To maximise performance, other modifications were carried out, as you'd expect.
- exhaust: A complete Miltek line has been installed, eliminating the central intermediary and optimising the flow of exhaust gases.
- Intake: We tried to install Eventuri intakes, but modifications were required to adapt it to the new turbo set.
- Filtration: A BMC air filter was integrated into the original airbox to improve air intake.
- heat exchanger: A Wagner heat exchanger was installed for better temperature management.
- Gearbox reprogramming: To complete the package and ensure that everything runs perfectly, we also reprogrammed the gearbox.
Optimising the fuel system
An important aspect of the preparation was the improvement of the fuel system. Although we considered the option of opening up the intake pipe to fit additional injectors and replace the low-pressure pump, in the end we opted to retain a Stage 3 without extreme modifications to the fuel.
Milltek exhaust system BMW M2 G87
As far as the exhaust system is concerned, the Milltek teams have come up with something crazy, with a sound that's, well, crazy! We made a video dedicated to stage 2, which we invite you to watch. But to sum up, we start with the two downpipes to remove the particulate filter, do away with the intermediate, keep the lambda probes, valve system for perfect sound managementin short, a very fine piece of kit which, if you haven't heard it yet, really, really sings loud!
Chassis improvements with KW V5 Clubsport
Having optimised the engine, we've also invested in the chassis to ensure that the extra power is efficiently transmitted to the road.
- Suspension: We fitted KW V5 shock absorbers for better handling control.
- Wheels: Forged Apex wheels were chosen, accompanied by Trofeo tyres to improve grip.
- Geometry: The geometry was adjusted to maximise the tyres' contact with the road.
Once Jordan had adjusted the set-up, you can clearly feel the difference between the'Before' and 'After' settings, and you finally have a machine that runs hard with a real chassis feel.
Improved braking with competition gear!
With the increase in power, the braking system also needed to be strengthened. So we replaced the original brakes with AMG GT brakes, which offer better performance under hard braking. The ventilation of the discs has a lot to do with this type of braking system, which is designed to perform over time and despite high temperatures.
Aesthetic modifications
In addition to performance, the M2 G87 has also undergone cosmetic changes. These improvements are not just for style, but also contribute to aerodynamics.
- Body protection: A matt PPF protective film has been applied to the front end to prevent damage from stone chips.
- carbon elements: Carbon additions such as a spoiler and a front blade have been fitted to improve aesthetics.
- Lights: Yellow lights (heritage M4 CSL and other vehicles in the range) have been added for a retro touch thanks to an LED kit.
- Neon lights: To complete the look, the neon lights under the car have been brought up to date. here at the editors, Renaud has given it his all! #GetLow
We love Need for Speed Underground, so we love neon. Back to the 2000's.
Mapping and Performance
Once all the modifications had been made, it was time to map the engine. This final process is there to measure and ensure that all the parts work in harmony and achieve the desired performance.
- Measured power: In the tests, the M2 achieved 930 bhp with an ethanol blend, which is an excellent result for a Stage 3.
- Torque management: Limits had to be set on torque management to avoid tyre spin.
Original VS Stage 3
To give you an idea of how the power gains between the original and Stage 3 compare, we've put together a little summary table.
| Power | Torque | |
| Original | 480 bhp | 600 Nm |
| Stage 1 | 650 bhp | 850 Nm |
| Stage 2 | 700 bhp | 900 Nm |
| Stage 3 (M2 Shiftech) | 930 bhp | 1100 Nm |
Road test
After the mapping, we took the car for a test drive to see how it performed. The torque pick-up at low revs was particularly impressive, which made driving very enjoyable.
Conclusion
Preparing the M2 G87 was an ambitious and successful project. With 930bhp and 1100Nm at the rear wheels, this car is now ready to take on the track with incredible power and a finely tuned chassis. Each modification has been carefully chosen to improve both performance and aesthetics.
