An upgrade to the M274 petrol injectors that produces 211 horsepower

[AmericaMonster]

Greetings, I am the proud owner of a 2.0T Infiniti Q50 equipped with the M274 engine.

Please find attached the original part number for the fuel injectors that I am trying to replace: A2780700687.

I appreciate it in advance.

Just what are you hoping to accomplish by making this upgrade?....more fuel efficiency?....smoother operation? There isn't much benefit to switching injectors unless you're planning on a huge power increase that requires a lot of additional fuel. So long as you don't intend to track or drag your vehicle after a heavy tune—in which case you'll need to keep the throttle open all the time—stock injectors will be more than enough to power the engine at full throttle under heavy load without running lean. Tuned AMG E63s with 1000 horsepower are using pump fuel with factory injectors.

The response is much appreciated. Since I intend to upgrade to Stage 1 with E85 if at all possible and my present injectors are malfunctioning, I figured it wouldn't hurt to have more efficient injectors.

The high-pressure pump was the downfall of this "Stage 1 + E85" upgrade that I had previously attempted.

So, I was wondering if there are any other injectors that are more powerful and if there is a high-pressure pump that can be upgraded.
