Is that a secondary air injector upgrade? -connected to the line running over your valve cover

I drive 2000 328i for my daily driver. Can’t say much about race applications, but I’m lucky to get 2 years out of a set of lower control arms. Maybe I’ll try a set of the Meyle and see if I have any better luck. Thanks for the video.

Curious: Based on your explanation of “why”, it sounds like this really isn’t worth doing on my 2003 325ci daily driver. Thoughts? TIA

Anyone knows the part number for the inlet rubber boot ?

Really well thought out.. well done

Where do I go in ista to run this test?

Minus work on a m54b30

M50 swap on m54b30 is minus work.. no gains. Even on high rpm.

One thing that isn't clear in any swap M50 intake on M54 videos is that isn't explained where the vacuum hose exactly need to be attched. M50 has FRP pipe directly in the intake. M54 have the FRP pipe that comes from fuel filter into an "F" plastic between throttle and MAF. So totally different vacuum behaivour. So where is the correct location of FRP pipe on this intake swap?

Thanks! Good explanation with tools around the garage already.

(short queston; are you running a PCV on the crank case vent hose to the catch can?) I'm having issues with my catch can set up, slightly different from yours, I blew out 2 rear main seals before i figured it was the catch can. (oil cap test done to see if it was building crank case pressure, it was not) (also ran a compression test within factory tolerances) I am dumping to atmosphere now and seems to be doing much better but I still have to replace rear main from the last blow out so leaks only slowed down. Ive seen some videos running pcv's some without, was getting your opinion. cheers!

Hey brother, If I'm understanding the video correctly, you shouldn't need to remove the timing chain either to do this? Thanks in advance

I made the m50 intake mani swap in my e46 eith m52tu and it runs and idles great, i got a stage 4 revmatch tune but im having a low rpm hesitation, any ideas? Ive heard could need a different spray pattern injector?

Great fabrication, do you have any sort of measurements? I'd like to try and make a baffle myself. Cheers

Well done Nick. Awesome pressure. Congrats on a P1 and P2 finish for the weekend. AMAZING

does this setup work? if so, i copy it to my m52b28 with m50 intake.

Its amazing to think of how recently these manifolds were affordable.

Since you are very much informed about BMW's, I want to ask a question not related to this video. What is the best torque converter automatic gearbox to install on a tight budget with an M50 supercharged engine and which parts are needed? It must have at least 5 forward gears with lock-up in the higher gears and fit without an adaptor plate. I can only find videos of people converting to manual boxes, but I need to go from my 5 speed to auto due to health issues. If possible do you know of a reputable supplier? The 6HP and 8HP boxes are too expensive and I am not able to find secondhand control units and/or shifters. Your advice will be highly appreciated.

What size are the tap screws to plug the holes?

Doing this today wish me luck! Cars already up in the air and exhaust is off as I’m in the process of changing the clutch just waiting for parts had a diff laying around for ages so nows the time to do it!

It feels slow

I just got done installing the M50 manifold on my M54B30. everything is hooked up correctly, and now it seems to have a misfire at lower RPM. when revving up, it seems to smooth out in the upper RPM range. I used your suggested Bosch injectors from the video. Any idea what could be wrong? Maybe just have to drive it so the DME can "learn" the new manifold? I kept the CCV system, deleted DISA valve, did not port match the intake ports on the head.

Where can I buy n54 harness? I found only connector without wires...

Do you feel the difference ?

For your oil hole, did you just cap it with a bolt?

Nigga just stood in front of the car and talked

Awesome vid bro ! Love how you actually take us through it step by step not leaving anything out.

Thank you very much, this helped alot!

So does the m50 cylinder head have bigger ports, If so wouldn't grinding the m54 head too match be an idea?, Is m50 duel vanos? what's stopping us putting m50 head on with the ports to match

Craig, how about pointers for a build of an M50 motor using an Eaton M65 from a kompressor Mercedes. I love what you did with the idle control valve.

please can you explain the setup of your catch can?

Hello, you have to tune the computer after installing that manifold.

how is that oil catch can holding up ?

Amazing video, i will be replicating this on my back tomorrow afternoon. Cheers

but the idle valve electronically is there any cable to which it should be connected or should only the pipes be placed without any electrical connection?

What adapter did you use for the throttle body?

Hi. You can get the compression values/ranges from within ISTA under troubleshooting/repair.

Where did you get the aftermarket CCV system from?

Hi Craig/Nicholas and/or Rory, so I am a new owner of an E46 with the M54 motor. I have watched almost all of your videos regarding your E46 build. They are great and really insightful. I am hoping to do something similar regarding my cooling system. Please can you elaborate or perhaps make a video on replacing the standard expansion tank with the round golf water bottle one as I am really wanting to do this but cannot find any info on this. Hope to see you at the track (I am in Cape Town). Thanks

I have 2 m50 motor cars one has an m50 manifold with an RK tune flash one is stock. The swapped one makes over 20hp more. Its extremely worth it.

b25 or b30 engine ? hows the oil consumption

Excellent video.....answered all my questions when researching for this mod. Only thing you missed was details about tuning, especially with the different injectors. Does it need to be tuned or not? Also you mentioned the catch can for the oil at the beginning but didn't go into details.

With the bosch injectors you need to run spacers or is not neccesary?

if coolant goes too long without being changed it can become very corrosive and can lead to shit like this happening

Well done on P3

YES! MORE RACING! woohooo!

I got this on my s52

Very nice

If you take your ignition coils out there's no need to pull a fuel pump fuse or relay the engine is not going to start while doing a compression test.

Тяжело мотору 😂
