M50 Manifold To M54B30 Adapter Kit
This intake manifold adapter kit simplifies the engine compartment and increases the overall performance. It is normal to see about a 20hp increase, better throttle response, and higher redline due to the increased runner size.
The M54 intake manifold does perform better in street driving due to the integrated DISA valve that can control the intake runner length depending on engine RPM and load. In a high performance environment, like at the race track, the engine almost never sees the lower RPM band. Making the DISA valve more of a liability, and less of a benefit. The flap inside of the DISA valve is known for failing, and can cause damage to the engine if any fragments from a failed DISA valve get into the cylinder head.
The throttle body adapter is CNC machined from 6061 aluminum. It is port matched to optimize air flow and velocity.
The fuel rail adapters that are included make it so that you can utilize the stock M54B30 fuel rail. You will need to cut off the stock fuel rail mounts. This is easy to do with a Dremel. Please make sure all of the fuel has been evacuated from the fuel rail before modifying it to prevent a possible fire. These are laser cut from 304 stainless steel.
An idle air control bracket is included. This supports the weight of the ICV, and prevents premature failure of the ICV hoses. The bracket is laser cut from 304 stainless steel, and the rubber holder is 3d printed to prevent unwanted vibration being applied to the ICV.
What’s Included:
Throttle Body Adapter
x2 Fuel Rail Adapter Brackets
ICV Bracket
x4 M6x1.0 50mm Long Bolts
x4 M6x1.0 16mm Long Bolts
x5 M6x1.0 10mm Long Bolts
x9 M6 Washers
x6 M10 Set Screws
Tips:
The air injection ports on the cylinder head have to be blocked off to prevent vacuum leaks. M10 set screws are supplied to close off these ports. You will need to tap these port to M10x1.25, and then insert the set screws with sealant. You will want to make sure the intake valves on the cylinder you are working on is closed. Make sure you thoroughly clean the port and intake runner you are working on before proceeding to the next cylinder. This is very critical to prevent metal shaving getting into the engine.
I suggest using a m50 intake boot, and ICV hoses. If you need help with part numbers for these, please feel free to reach out to me and I can help you get this info.
I also suggest replacing the intake manifold and throttle body seals. These intake manifolds are at least 25 years old now, and reusing old gaskets here can cause vacuum leaks causing a poor running condition and low power.
