Making My N54 Fast AND Reliable! (Road to 700HP+)

In this installment, we're continuing with the N54 build for my 2009 BMW 135i M-Sport. If you've watched the previous episode, the front turbo decided to eat a couple steel screw driver bits, spit them into the outlet and intercooler, while also puking it's metal guts into the intake track, intake of the engine and throughout the oiling system itself! (stripper glitter, EVERYWHERE!)

yeahhhh, needless to say, I could not trust that engine, so this lemon-flavored long-block was sourced. In this video, we install the hot-parts for the ON3 single turbo kit along with the aftermarket BMP forward-facing intake manifold. Everyone said I needed to get a walnut blaster so, I bought and completed the blasting myself as well. - I think they turned out good, what do you think?

We're one step closed to putting down some good, solid numbers with this project. Are we still within budget? hard to say, it might be close! Stay tuned!

N54 is de wey 🙌🏾❤. Just take care of it and it will bring you endless smiles and compliments

[khemchee]

This is one of the best n54 YouTube channels. You actually explain things and show all the details on installations.

[joshuaquilliam]

Good stuff guys, good to see folks still pushing the N54. Great video!

[karemzahrdein]

Nice build man!!! A lot of inspiration and knowledge from this video 👌🏻

[friguy]

I always learn something useful or new (Both? LOL). When I watch your videos! Thank you!

[BMWM]

I've watched a pretty large number of N54 builds, and can say, great job!

Best of luck with the "reliable" goal if you push much over 500whp though... been there, done that, and again, and again, and again. (And doing it again, again) 🤣

[twitchkillgod]

Love to see it i plan on doing my project soon 900+hp

When I walnut blast I use a carb cleaner to help clean and loosen the carbon. I also use it to verify valves are sealed. Spray some in the port, if it sits in there you know its safe to blast.

[BrokeMahWallet]

Never knew you had a 1 series 🔥🔥. I just picked one up a month ago n55 variant tho.

[billyringoable]

Nice exhaust manifold so sad they dont make it t4...what s the a/r on the exhaust hausing?

[ArticulateArena]

wish I wasn't so severly restricted most of my life. I thought flipping burgers was / being a manager was peak life. Now i'm almost 40 broke and aimless. I got a good priced 128i but now my insurance is more than the car for some reason haha. I want to do upgrades to it for power and for looks. I got it with some mods already and looks insanely good but I can't even do the bare minimum maintenance. I'll never be able to do anything like this to it.

I wish I had the childhood of all these people doing stuff like this and even bigger crazier things that make

Just fyi. I have the exact same ff intake manifold as that. The company welded the throttle body flange 90° off. If you look at other FF manifolds, the bolt hole should be at an angle to the manifold. Otherwise the throttle body doesn't sit correctly and hits the alternator. The company sent me an adapter to rotate it so it doesn't hit now.

I also have the 335d reservoir. I had to space it up so it didn't rub on the manifold.

How is the eBay engine oil cooler doing on the other 335i? Thinking about buying one thanks.

[PartiBuoy]

oil pan bolts are very misleading being feather light tension as well

[ti_totheger]

The Front facing intake manifold, any reason why you choose that over the stock location? I’ve read that FF has a better top end power but worse mid range. Was planning on running one when I go down the port injection route. Just got a single turbo. Want to keep the engine from blowing thinking having that reduced torque mid range is better plus you get a good bit or air flow top end. Just wondering your thoughts

Canadian fellow here. Did my 1st run on my E91 swapped ST a week ago. Then I was confident to go to the exhaust shop to have a single exit for that sweet L6 sound. Annnnd the serpentine belt flew away. got back on a towing.
Ive started a post on e90post, feel free to comment !

[msalamlaham]

How did you buy the On 3 ST kit in Canada? shows that it only ships in the US

[arilamar]

Should have done rod bearings and upgraded crankhub possibly do timing chain oil pump chain and guides

[NTromb]

15:59 Why is it a major part like that is plastic and not steel or stainless steel or something like that😢 I mean, obviously, it’s engineered for that but still

[steen]

tbh thought that the video was going to be installing a downpipe and tune
