For about 4 years ive been trying to find a complete video. On a swap like this. My bro you earned my subscription..💯💯💯
Please KEEP GOING youre doing exactly what I want to do with my e46 sedan
You are a pioneer and a gotdamn hero. Please keep the content on this build coming.
Can you make a video on just the wiring?
Cool swap
I came here from your comment to another video, would love to know more about wireing/programming/ecu
@@Shari_Tejp not something we can teach at the moment but there’s other companies that make conversion harnesses

Awesome build, the e46 diesel part is very interesting, along with the m3 ones. Gives me ideas for my e46 supercharged build. The only thing i dont get is your massive hot air intake going over the car into the void of the driver side. You should probably try to get the filter around the fog light area on the turbo side, or behind the headlight, with a tube coming from the fog light to the filter like ill do on the driver side.
I wish i could install this 6 spd on my m54. They seem way less expensive than true 6 spd swap from an e46. 5spd to 6spd swap im probably looking at 2 thousand euros... but the 3.46 diff hits hard on the highway.
Thanks Lorri, I don’t recommend supercharging the M54 to anyone. It’s a heat soaking machine. Sadly, the gains are very minimal. We tried both turbo m54 and SC in the past and the n55 swap is by far the easiest to work on with no tight spaces.Everything is very accessible unlike the m54. Don’t get me wrong, the m54 is a great engine if left alone and is very capable, if built correctly. I will always love the m54 lol.
We are well aware of the hot air intake. Eventually we will plumb it down by the fog light, although IATs are still below under boost.
There’s still work to be done ☑️ along with a/c and heater lines.
By the way you can use this same transmission (e90 37bz on the m54 as well. Here’s the link 🔗 ruclips.net/video/Jo9P74fHWy0/видео.htmlsi=XlSifbOAY-qpNHR7
Love the build! Do you gonna make more parts of the build? 🙏
Yes hopefully soon we will go over the intecooler piping set up
Great. Would also be cool to see a B58 swap
That would be cool! Unfortunately that engine requires more fabrication, time and money. This is why we picked the n55 mainly for it’s simplicity.
@@TecKnowTech I’m sure you will be able to do it eventually) I am also glad you picked an n55, and not the n54. Too many people are poopooing the n55, but it’s good if done right and sounds awesome. Great job!
@@TecKnowTechwhat makes it more complicated?? Mounts? Electrical?
@@Tony-RS3 I know we can do it, it’s the cost 💲 that doesn’t make sense. Definitely more modifications & time and it’s not something a regular joe like us can just do in the garage. The n55 on the other hand can be done at home with most of the parts being plug and play and it being single turbo makes everything so much simpler and easy to work on 🔧.
All we need is A/c function 😅
@@TecKnowTech ok I’ll loom into a n55 build, e46 with 600-700whp is enough anyways! Need more hybrid setups tho, is there more room on the turbo side? And you got the cluster going I see, still need the e9x cluster connected or not?
I’d really like to know what was done in terms of wiring to get the engine to run and to have all the signals to the dash working.
@@CALLACI it’s a very tedious process…
But there is another option www.ebay.com/itm/143901394744?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=3iaTpqv0R6-&sssrc=4429486&ssuid=_mErjLJHQs2&var=&widget_ver=artemis&media=COPY
Hii no wiring guide ?
No, not at this time. The wiring can be complicated if done incorrectly, can possibly damage modules. I’m offering custom harness to locals in California only at this time, maybe in the future we will expand….
Although there’s another company in Portugal 🇵🇹 that’s making harness kits for n54/n52. If enough of us request a n55 kit they can possibly start making them. Here’s the link send them a message..

@@TecKnowTech Is it possible to do the opposite? I have an N46 engine in my E90 and want to swap it for an M52
rod bearings spun happens bacause of electrical oil valve,i locked it 30 times on n55 engines, let me know if you need info
Please dm me on instagram. We had a feeling that valve is the culprit. I heard even some of the high hp b58 guys are leaving the valve disconnected defaults to max oil pressure.

This is dope ! What made you go with this setup ?
The video speaks for itself 🫡!
No expensive aftermarket engine/transmission mounts or driveshafts &
the car drives like factory which is what we wanted.
We found it very easy to fit one of these engines into a e46 chassis. It’s a simple engine being that it’s single turbo with no clutter. Anyone that’s mechanically inclined can install one in a few days.
@@TecKnowTech fire bro ! Definitely a dope setup 🫡💯💯
How many miles on that engine is that RB bad for how many miles it has or normal?
@@aombarbor I think it was 134k on this engine.
Typically you do not want to see any wear. These look like the first layer of the bearings material was starting to show.
I always recommend them whenever someone come in for an oil pan gasket replacement. Just for peace of mind!
Do you know what you're going to do for AC yet?
So far it Looks like only one a/c line needs to be made for the e90 compressor to work with the e46 chassis.
@@TecKnowTech and it would work with e46 climate control?
