Today we go deep into my OBD1 M50 Intake swap on a M52TU engine. It was the first time I did this exact modification from start to finish. If there's anything I may have missed or should explain further please let me know!!!!
Awesome video made me more confident during my swap. I ran into the same nuances and came up with similar solutions but felt crazy doing it. Thanks a lot!
I just picked up a super clean Z3 and I really appreciate the video. Learned so much. I hope your Turbo update is as thorough as this video. Thx
Love the build...back in days i had a bmw 325i 1987 miss that car...here supporting your journey brother . blessings ✌
this is probably the most "info" and "how to" rich video on swaping the intake on those .... im loving it bro, keep up the brilliant work !
I bought a 2000 323i this video was super helpful and I am glad someone else agrees on how annoying the vacuum lines can be
Hell yeah bro was wondering when we would see a new video! This build is really growing on many of us and just a kick ass project. Can't wait to see her ripping up the track! It is going to be so worth it!
great video watched the whole thing, definitely helpful haven’t seen someone document the whole swap. thank you for this!
Great video. Lots of good information on swapping that intake.
Thanks for the concrete expression, it is very useful for my entrance project, but in aluminum, I will do it turbo.
That is the best DIY video on KZhead!! Big like and big respect to u buddy
Excellent build. When you do the fuel injector harness if you flip them the tab to unlock them will be on the bottom and will be hard to get to to remove.
there is certainly a bigger cleanup, that make things better from this point, with this intake. But on the m52/54 intake ,those small diameter tubes, are for low to mid range rpm, and they are narrower, because for that given volume of air ,at that rpm, the speed of the air to be higher. Then the Disa valve, change the route of the air incoming towards the valves, by those big fat shorter pipes, from underneath the manifold, and the engine gets a lot of ai for high rpm. So for street use is a very good itake manifold.
Awesome vid man. One cool little trick is to buy those Gel Keyboard cleaners (2 x4 packs) and put them in the ports (1 per port do not reuse) a little extra insurance. Everything sticks to it! Then obviously the vacuum to be sure
This video very helpful indeed. Thank you so much
Ben! Awesome job bro! Doing the same with my M52tub28/ 3.0 stroker
And? Are you happy? How much HP and nm did IT
Looking good Ben!!!
I'm actually super happy I stumbled across this video because it's super useful for me. I'm building my old 1999 328i that has the same motor and have considered this swap and will be eventually doing a fully built turbo setup
Doing a 1999 328i right now . Trying to throw the manifold on atm
@@gavinsixnine how’d it go doing the exact same thing on mine 1999 328i
@@diegom.9762 went well. Didnt use any kit to swap . Didnt wanna spend another 200 bucks. The throttle body is sideways to fit onto the manifold without an adapter plate. Works fine, ran the cable up thru where the brake booster is then to the TB. There is ICV ports that you need to plug. You get a tap tool and makes some threads in there then put some screws in it to plug. Make sure you got a towel or rags / vacuum ontop of ur valves to not get anything in there. You can hear the manifold alot it do be sucky sucking . Makes more power and didnt really feel any torque loss tbh. Top ends super fun. With tune rn makes about 260
@@gavinsixnine wtf 260? Yup thank you for the rapid response 👍👌I just ordered mine today
@@diegom.9762 its the 2.8l makes 190 stock and with full bolt ons and a stage 4 tune i do believe that number . I have a diagnostic readers app that tells your horsepower and after many pulls and tests 260 was average. I do believe its in the ball park
I think that the m54 throttle bodies are larger. Could be something to look into if you want to upgrade it!
That m50 air intake mani looks soooooo much better than the stock one. A mo Powa bebeh
I dig the roll cage
Maybe a dumb idea but I was thinking... Wad up some inside out blue painters tape into an appropriate sized ballish shape and shove that in very first step. Try to squish it down close to the valves. Then do the cloth/towel or whatever etc. That way any shavings that may make it past "should" stick to the tape". Anyway, love your work dude. :)
Such a helpful video!! Question though, with the port on the bottom of the intake manifold, did you leave that venting to atmosphere as well? Its the small little one on the under side, near cabin of the car. Does that stay open?
Καλησπερα ειμαι απο ΕΛΛΑΔΑ! Το βίντεό σου είναι υπέροχο!!!
Hi, Great video, doing the same thing on my E46, just one question, did You use the stock injectors form the 2.8?🤔 Thanks 😊
What did you use to port match? I have a dremel, but not sure if there’s something better? Great video!
Very inspiring video! Do you think after doing this can I still smog my car? Lol just curious.
Wow you are a genius 👏
Nice work. If you can elaborate a bit on why you had to flip injector wire clips? I'm doing the conversion on m52tu z3 roadster with engine out, got all parts needed, I think. Planning way ahead and I'm concerned about why you had to flip your injector wire harness connectors. Will I also have to flip mine? I have same throttle body, any suggestions? Everything I have is the same as yours except I'm keeping ccvc and secondary air, any hidden problems? The injection has me head scratching. Any help would be very valuable to me. Awesome build.
You should really do that video on porting the head it would be great so I could do it to
Sorry I commented so many times. Lol! Regarding the sensor you threaded into the manifold. That was freeking AWESOME! But... Since you hang with the Cleet gang, think about RMRW. A fitting like that would SUCK to try to replace in the middle of nowhere. Just my .02, which in reality probably isn't worth even that to you Ben. :)
That is a good point! If I had a stock sensor and die I could probably make one on the side of the road if I had to. I’ve personally have never one go bad but like you said there is a downside to doing custom stuff like this.
call me a copycat all you want i need that same exhaust set up XD that looks so good
I did an n54 turbo manifold onto the m54b30 with the m62 4.4 v8 throttle body and zhp cams its a beast mated to a getrag420
That sounds amazing wtf🔥🔥ima do the same thing now
Do you have an instagram?
My daily is a 330 e46 coupe great engine. Love rainy days 😏
You have the exact one I’m tryna sell my 325 sedan for😂
This is such a sick video but came about 1 month too late 😂. Only question i got is how did you get the nut on on both side at end? Like where the vanos and fuel line is?
I know this is an old video but I was wondering what you did with the purge valve? I’m doing the swap now and just want to double check my work. Trying to make sure no lights come on before I crank her up. Thanks.
Hey man what rubber tubing did you use for the ICV?
Could you please tell me real quick what throttle body boot you used. Does it work with the idle air control valve? I am at the point where I finished my plate for TB, and I have little room for boot. I relocated my obd so it's not in way, heater control is relocated. M50 manifold is fitted. Keeping my secondary air pump and the ccvv. Just need to know how you set up your throttle body boot setup. Weeeeeee. Thank you so much for your help
hey there! i was just wondering what you did about the throttle cable placement? how do you have it held up nicely? also please do a video if you do the m54 drive by wire conversion. i’ve been looking everywhere and i can’t find it
Doing this today and I'm stuck on the same thing. Will let you know if I figure it out...
@@TerpTalkGarage hey boss, did you every figure out the throttle cable placement?
What are the exhaust pipes on the side for and what's it connected to the manifold output?? It looks like a dump pipe correct??
B-Ben’s M-Modded W-Whips
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?
I did the m50b25 intake swap on my m52tub28, but the original valve cover doesn't fit now, any fix for this? An other cover that might fit?
Hey man I own a 2001 bmw 330I and I’m in high school I’d like to think I have a lot of really good knowledge on cars but I always love to learn more considering I’m in high school I want a simpler engine bay and more reliability out of my car so I want to delete as much unnecessary things as possible but when it comes to the E46 there is not nearly as much info out there on say like a SR20 or the JZs I was wondering if we could get in contact somehow and I could talk over a few options when it comes to this. Thank you for your time and the video was amazing helped me get a better understanding of a lot and learn some new tricks to use!
Hey buddy. Check out my video on the M50 manifold swap That allows for a lot of clean up to your e46. Find yourself or someone who can code your computer. I was able to delete: A/C, Heat, secondary air pump, post cat o2 sensors, DISA valve, EVAP System and I'm sure much more that I can't think of off hand.
Bayside Fabrication I’ll go Check out the video! The main things that I would like to get rid of is the SAP, the disa valve, the CCV, and all the other extra junk besides my A/C I live in Arizona so no chance I can’t have that but I’ve been looking into a new intake manifold and really there is only really two ways to go ether you use a m50 intake or a custom made after market one that typically ditch the old throttle body for a cable one I was wondering what one seemed like the better option. Clearly both will make a better gain in power due to better air flow but I was wondering what one will be better in reliability, serviceability, and cost effective.
M50 manifolds can be had for cheap I would go that route. You’ll need to port match intake however.
Bayside Fabrication not to hard to do however with a little patience and attention to detail it can be simple to help the air travel in smother. I appreciate the help man I was feeling a little lost because hand
@@baysidefabrication there is certainly a bigger cleanup, that make things better from this point, with this intake.

How did you put back the wired throttle body to the M50 manifold??
Where did u find the M50 gasket you used? I can’t find one 🤣
For the throttle body put the throttle body on normal then put a 90 sticking up with a cone on it
How'd you mount that little bracket to the throttle body?
how does this effect your emissions, i am in california so the regulations are quite strict? really want to do this! great vid
You can not do any modifications to your motor in California.
umm what did you do to the hose that comes off valve cover ?
What do you know about an m50b25 intake manifold fitting on a m54b30 engine?
Any recommendations for a head gasket brand for a m52??
Do you have to port or you recommend the port
Center 2 runners get more air, unless there is a disperser for the air coming in
Did you have to drill the holes out on the templates for the first and last ports? Mine don't line up for some reason on those ports but work fine for 2,3,4 and 5.....
Did you ever sort this out? Having the same issue!
I just had to modify one of the templates as per SLG advice.
u sound like the food wishes guy
where did you find the templates for admission?
Bro i cant find m50b25 manifold in my country i found m50b20 intake can i install it on my m52tub28?
Is the port matching necessary?
Hey man nice vid! Would this conversion work on M54 engine as well?? Thanks!
Hey, Quad, probably you've already answered your question but anyway, here it goes: it does work with the M54 and apparently it's a well known mod. The only thing I would watch out is the lower-rev power loss you'll have after deleting the Disa valve. This mod will do its tricks at high revs.
Where do you get the block plugs
I did the swap and when I turn on the car in the morning is stalls after 25 seconds it goes away and won’t stall again it’s just in cold start any idea guys ?
Doing the same to my m54 currently, did you delete the evap purge valve too or leave it plugged in and just tuck it out of the way?
what did you do with the evap? when i bought my m50 mani it was already blocked w rtv. about to do it in couple days. waiting for the m50 conversion. thanks !
@@anpredictable you can either run the evap purge valve to a npt barb fitting back near the brake booster on the mani. There are two blank ports that you can drill and tap. If not I just left my valve venting to atmosphere
@@sups1264 below that FPR is the stock m50 air sensor? So i can use that for evap? Im planning relocating my air sensor before the throttle body on the air intake boot. Rather not let it out of the atmosphere. Itll be uncomfortablr and bad for atmosphere lol
@@anpredictable no behind the brake booster port there are two indents. They are not actual ports but can be drilled out and tapped to fit extra barbed fittings for things like the sap and evap, or even boost gauges and wastegates. Look on the side of the intake manifold you will see them. I’ve never seen anyone relocate the iat sensor so I can’t really comment on that idea, but if you are going to relocate that you could definitely use the old threaded hole for the evap line
@@sups1264 oh yea i just cleaned them out and there was 2 closed indents. thanks. i just ordered a new icv connector only $7. but i need to carefully remove the rtv tho. thanks for the input. i may go on that. still waiting on the m50 stuff and the icv head black off
Does it work on m52b20?
👍🏻
Hey man, how come so many forums say you can't put a M50 manifold on a dual vanos engine like the M52tub28?
Because most people on forums now a days aren't people who do actual work. Most just spit other other peoples opinions. Back in the day the forums were the epicenter of new information. Now its dead.
did u use 1/8 npt tap? im also trying to find a way to block those ICV port
Yes. No need to drill out holes. Tap existing holes and your good to go.
I'm trying to understand the whole port Tapp thing
How did u reset the engine ?
I have an 03 325i, it is now a 1/3 mile oval dirt track car. I run it 4k rpm to redline. Would this intake benefit me? Mine ia a 5 speed and needs about 15hp and 400rpm to dominate the field.
If all you need is 15hp & 400 rpm, then swapping in a 3 liter engine would get you an extra 40 hp or so, and a 'zhp' tune of the dme would also raise the rev limiter / redline.
@@LeverPhile I have been told the 3.0 can't handle more rpm than stock. It is on the planning list to do but is that accurate?
Can I do this upgrade to my 05 e60 l6
I know you better than "inspect" vacuum lines. For like 100 bucks you can for sure replace them all. Then you don't have to think about them again. :)
So I randomly stumbled across this video and you mentioned The shop you got help from. I wanted to see how far away it was and it turns out in literally 3 minutes from my house in Ocean Springs. Just thought that was kind of weird.
I got a 99 323i and about to do the m50 mani swap but stuck at the throttle wire is to long
Iac valve needs to be tuned out properly my man!!
Are you running any catch can now?
Car is sold but yeah I build a big catch can for it.
@@baysidefabrication idk how to send a direct messege but i have another question. TIA
sick video ! i wish i could do this my beamer is stuck in a limp mode aha its giving me throttle body codes, replaced it with two used ones then a remanufactured one and still no luck .-.
Did you have to tune it?
Ofcourse
does bayside mean near San Francisco?
About as far from San Francisco as you can get. I’m in Florida
@@baysidefabrication darn, well I love the Z kart. Keep up the good work!
what is z kart
will this work on 2000 bmw 323i?
im thinking of doing this on my 323i ... ive figured out most but for some things im still looking for answers
How about the DISA valve?
Deleted!!!!!
Specify delete. I attempted with my m52tu and DISA fault could not be coded out
@@MrRalph0000 what will disa fault code cause? you can just leave it with fault code yeah?
Can you do this do the M54B25 too?
That’s what this motor is.
You can if you want to lose power, even na B28 would better of whit m54 B22/B25 intake, its been measured. I suppose M50 intake is good for turbo aplications and thats where misconseption comes that it would be great for every na engine there is.
@@winha1435 it’s good ion even have a b25 anymore I’ve had a b30 for a while now but thank you for the input sir have a good day😎
Dump them coils in the trash 😂
Why not get a m50 motor which are actually better than the m52
Completely pointless mod if u don't port match the inlets
It’s a good thing I did.
So many proven m50 manifold swaps and this guys over here trying to reinvent the wheel??? Video should be titled "what not to do"..
It works great!!! Not sure why the negativity but it’s all good man.
