N54 Stage 4 LPFP Upgrade Stage 4 LPFP kits are similar to stage 3, however it requires the use of port injection. The dual pump set up is the same as with the stage 3 kit.

Can you add port injection to direct injection?
“These are what we call port plates, which allow you to add port injection to your otherwise direct-injected engine. These are for LT1 and LT4 engines,” says Mike Sitar of TooHighPSI Performance. On display are a set of plates designed specifically around Magnuson’s 2650 supercharger system.
What does a port injection kit do?
Port Injection is a kit that installs between the intake manifold and cylinder head and runs on a low pressure supply to deliver more fuel to the engine than the stock system can do.
Does BMW use port injection?
Prior to the switch to direct injection, most BMW engines were powered by port injection. Direct and port injection are similar in many facets. Both injection systems utilize computer-controlled fuel injectors to spray fuel into the cylinders; the difference lies wherein fuel sprays into the engine.
How much power can stock N54 injectors handle?
The N54 on stock internals should be left around no more than 600whp/wtq. Anything beyond that to about 850whp should have at a minimum upgraded pistons and rods and better bearings.
What do I need to run full E85 on N54?
On your stock N54 LPFP, you can handle up to about 40% E85 blended with 60% of 93 octane pump gas. With a stage 2 or 3 LPFP, you can run 100% E85 which creates even more power and is actually cheaper!
Is port injection better than direct injection?
Improved combustion efficiency As compared to Direct Injection, Port Fuel Injection is more efficient in terms of combustion. Drivers looking for the best of both worlds may save money on fuel while still enjoying the finest possible driving experience.
Does port injection have carbon build-up?
Gasoline Direct Injection (GDI) systems have unique carbon build-up issues on intake valves and ports. Detergent additives that are poured into a gas tank do not reach these carbon deposits.
Which is better MPI or GDI?
Which is better MPI or GDI? Compared to conventional MPI engines of a comparable size, the GDI engine provides approximately 10% greater output and torque at all speeds. In high-output mode, the GDI engine provides outstanding acceleration.
What does Port injection Do N54?
Port injection runs off the low-pressure fuel pump. Many N54’s start with LPFP upgrades on stock turbos to support more power and higher E85 mixes. This often looks something like a single Walbro 450 or Walbro 525 LPFP. Single pumps usually support about 450-550whp on 100% E85 with port injection.
Does JB4 control port injection?
SKU: PI Controller The Burger Motorsports JB4 Port Injection Controller attaches to the JB4 allowing it to directly control both traditional port injection kits and WMI port injection kits.
Does the S55 have port injection?
We have developed this port injection to fit the S55 motor that will provide you with the additional fueling needed in cars running 100% E-85, upgraded high performance turbos, or both!
Is BMW N54 direct injection?
The N54 was produced alongside the naturally aspirated BMW N53 engine; both engines have direct injection, double-VANOS (variable valve timing), an open-deck engine block and an electric water pump.
What does Di mean for BMW?
The ‘DI’ element of the TDI tag stands for ‘Direct Injection’, the most efficient way of getting fuel into the car’s cylinders. Traditionally both petrol and diesel engines used indirect injection, where fuel was injected outside the cylinder, a system that was a hangover from when cars used carburetors.
Is the M54 direct injected?
The BMW M54 is a naturally aspirated straight-6 petrol engine produced from 2000 to 2006.
Are N54 internals forged?
The rods are forged, however pistons are not. N54 rods are strong, but they’re not indestructable. A serious detonation event at 600+whp can quickly bend a rod. Cracked pistons also occur from time to time.
How long can a tuned N54 last?
The N54 itself is a very strong engine that can often last beyond 200,000 miles. Of course, that’s if you’re willing to keep up with all of the maintenance and repairs for that long. Even when modding the N54 engine it still retains good longevity.
How much boost can a N54 take?
Likewise, newer OEM turbos may decide to give out before 20psi. However, if you are concerned about N54 turbo longevity, somewhere in the ballpark of 17-18psi on stock inlets/outlets and 19-20psi on upgraded should be safe for most.
What happens if you put E85 in a BMW?
What is the octane of E85?
E85 has an octane rating ranging from 100-105, making it a high performance fuel. In comparison, regular unleaded gasoline has an octane rating of 87. What happens if I accidentally fuel my gasoline-powered vehicle with E85? No problems should occur if you mistakenly fuel once with E85.
Can you run straight E85?
The most common problem of running straight E85 is high pressure fuel pump, I would recommend those who want run straight E85 for long period of time or daily get a port injection system, it would be much more reliable. Range and difficulty finding pumps are my two downsides.
Does Port injection prevent carbon buildup?
For example, the fuel is able to flow over the intake valves in port-injection engines, which helps to keep the valves clean of carbon.
Does direct injection increase HP?
The technical answer is yes; fuel injectors can add 10 extra horsepower at peak. However, for some car owners, that minimal difference does not offset the increased cost and complexity of switching to fuel injectors or upgrading the existing stock fuel injectors.
How do you prevent carbon buildup on intake valves?
Preventing carbon build-up Change oil according to the manufacturer’s recommended change intervals and using the specified oil for optimal performance of the intake valves. Replace spark plugs at the recommended mileage to reduce the amount of unburned fuel in the combustion chamber.
Can carbon cleaning damage your engine?
There are no proven harms of getting your engine carbon cleaned especially if you go with a trusted company like engine carbon clean UK. Carbon cleaning undoubtedly has a lot of benefits for older cars that have lost their performance and have a decreased fuel efficiency. I would recommend you try it yourself.
