This Stage 1.5 Package adds the option of larger 21.5lb fuel injectors to the Stage 1 Euro HFM kit. The 21.5lb injectors (23lb at BMW's 3.5 bar) were standard on the S52 3.2-liter engines. Because that engine has found its way into many other E36s, we put this kit together to use the Euro HFM, intake, and the stock 3.2 injectors. Also, it's been necessary for some people to add more fuel to account for cleaner-burning gasoline used in the US. With the lower grade fuel, pinging, knocking, or lean conditions may be experienced with the stock 3.0 injectors. The issues people are having seem to be geography-related (California, the Northeast, etc.) but many people feel safer having a fuel 'safety net' and this Package meets their goals. We also offer a Stage 2 Package with 24lb injectors if these are still not flowing enough fuel. There is no performance gain with only adding the 21.5lb injectors.

We use the aFe 'Euro' Intake Kit, Bosch Euro HFM, Bosch 21.5lb injectors, and a special TMS Stage 1.5 Performance Chip. The aFe intake is made with heat-blocking materials, reducing underhood emperatures and not contributing to heat soak of the air filter. The aFE intake uses an oiled cotton air filter for maximum air flow and excellent filtration.

With the undersized stock air sensor, the M3 is gasping for breath. But with the larger 3.5� Euro HFM and Euro Intake, the M3�s engine can breathe a lot better. This kit works on all 1995-1999 M3s with the US S50 3.0-liter or S52 3.2-liter engine (and using OBD-I engine computer).

Our TMS Performance Chip is tuned specifically for the Euro HFM, aFe Intake, and 21.5lb injectors. Our chips require premium fuel (91 or higher) and allow us to alter the settings on the engine management.

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.
