Our Stage 3+ Package for the 1996-99 E36 M3 takes our Stage 2 Package and adds the Schrick performance camshafts, M50 manifold, and matching Stage 3+ Shark Injector software. Adding the M50 manifold produces huge power gains in the upper RPM. If you spend the majority of your time over 5000 RPM, you're going to love this kit. The parts in Stage 3 are our most-popular performance upgrades for the E36 M3: intake, cams, software, complemented by the M50 manifold. While Stages 1 and 2 focus mostly on making mid-range power, Stage 3+ shifts the focus entirely to the top end of the RPM. With the change in the manifold there is not much of a mid-range torque increase. The Conforti software keeps any torque loss to a minimum.
The aFe Euro intake is designed for a 3.5" HFM and includes a heat shield to block warm air from the engine compartment. The aFe intake uses an oiled cotton air filter for maximum air flow and excellent filtration. The kit is supplied complete with heat shield, intake tube, sealing materials, hardware, and install instructions.
Just like in Stage 2, we use the 3.5" HFM from the Porsche 911 (993), along with a custom wiring harness, to work with the Siemens DME and special Turner Motorsport/Conforti software. This HFM reads airflow far more accurately than less-expensive other HFMs on the market. That extra metering allows us to fine-tune the software to make the engine more responsive, smoother, and produce more power! From Stage 2 we learned that the stock 3.2 fuel injectors were nearly maxed out so we specified 24lb injectors for Stage 3.
Stage 3+ is designed for street cars that see a lot of runs to redline and the extra power over 5000 RPM is needed. Where the stock S52 manifold allows a drop in top-end power, the M50 manifold just keeps climbing on the dyno. To preserve engine life, the rev limit is set at 7000 RPM. We have matched the Schrick cams with the M50 manifold, larger HFM and Stage 3+ software to all work seamlessly and reliably. We prefer the Schrick camshafts because they have been bulletproof through all of our testing and development.
Related Upgrades. We are often asked what would complement our software and intake packages. Within any Stage, we recommend our Underdrive Power Pulley Kits and a cat-back exhaust. The Power Pulley Kit will under-drive the alternator, water pump, and power steering pump. Under-driving means each component is moving slower which requires less power. The saved horsepower is put back to the engine where it transfers to power at the wheels. Power gains are typically 10 horsepower at the wheels.
We also recommend upgrading the cat-back muffler for slightly more performance, lighter weight, and a more-aggressive sound. Our favorite E36 M3 mufflers are the Supersprint, Borla, or Corsa exhausts. The Supersprint is the quietest and most like stock while the Corsa is the most aggressive (Borla being in the middle). You can expect a gain of 5whp with any of these exhausts.
