If you’re a diehard N54 enthusiast, you know that there are very few aftermarket intake manifolds available for us. You might also know that Doc Race has been working to produce an intake manifold since 2016.
Once mass-production was confirmed, I had to get one to match my Doc Race N54 single turbo kit. One of the reasons I wanted this intake manifold was because it integrates port injectors directly into the manifold. The typical N54 port injection method (which I currently have) involves a spacer between the engine and stock intake manifold that creates an additional surface for potential boost leaks. Not only that, but it looks awesome too!
I tried MMP Stage 3 twin turbos, but never felt the “wow” factor I was hoping for. After worrying about wastegate rattle and smoking turbos for too long, I decided it was finally time to go big or go home. Meet the Doc Race N54 single turbo kit.
Once I decided to convert my N54 from twin turbos to a single turbo, I spend countless hours researching what kit I should go with, which parts needed to be replaced, what upgrades needed to be done, etc.
To save you that same hassle, I saved my parts list and will share that below. With this complete list, I was able to safely make 749whp on the stock motor in my BMW 135i.
I want to kick off this post with a reminder that I’m installing the Doc Race single turbo kit outside of the car on an engine stand. Part of the reason I bought this kit was because I blew my motor which required to me remove and re-install a new motor. Great excuse to upgrade… right?!
The kit showed up about 4 weeks after I ordered it and came complete. I didn’t want to gamble with other vendors’ long lead times and kits that arrived with missing or poor-fitting parts. Doc Race knocked it out of the park and I’m glad I chose their kit!
Everything looked beautiful. I opted for the ceramic coating option and a ball-bearing 6266 turbo. The kit includes almost everything you need to convert to single turbo! Now let’s get these beautiful pieces where they belong…
Manifold studs replaced, manifold, heat shield and water pipe installed.
As you can see, the Doc Race N54 Single Turbo kit is awesome. If you’re thinking about going the same route (which I would highly encourage), be sure to use discount code N54JAKE at checkout to save $100.
