After 20 years of being interested in car and car performance (starting with a 5.0 Foxbody Mustang), I watched a M3nace video and had the guts to remove my first intake manifold on my 323i to replace my starter. Thanks, M3nace. Also, the "might as well" clean/replace this while we're here tips are great too, so keep those coming!
3 Words: Multi Purpose Grease :D best e36 channel out here hands down
I actually learnt alot in this video. Thanks alot. I hope this will help me in re installing my manifold tomorrow.
Best tutorial on CZcams! I used the M50 fuel rail. There are just a few adjustments on the fuel lines. Way easier I think.
Im sure that works as well. did you replace the soft lines from the hardlines back?
@@M3NACE I cut the ends of the M52 fuel rail. So the quick connector is still in use. From these end pieces I use standard fuel line to connect these end pieces with the M50 fuel rail. On the rail are no adjustments needed. The top cover cannot be used anymore. But looks fine.
Yes i need this my 1998 m roadster s52 sure could use a bump in horsepower. Great vid thanks
Finally! been waiting on this video for so long
I plugged the connector for the Air-Temperature-Sensor on the original M50-Air-Temperature-Sensor on the right far side (on my E36 328i 1995 europe version) and it worked very good without warninglights or errors. (Nice video by the way!👍)
That's weird because the M50 uses the Bosch Motronic and M52 uses Siemens MS.41
@@noahlangens4542 no it's not weird, you are right about the bosch and the siemens, but the only thing that stupid little thing does is give a certain signal to the bosch or the siemens and when i did the m50 manifold swap i saw it was the same connector so i just said to myself try it and see if it works and it did!
Awwsome zip tie trick!! Definitely going to be used for many things going fowards hahahah the simplest tricks amuses me lol. Very helpful thank you!!
Of course!
Excellent tutorial.
Thanks from Australia
1995 328i M52 OBD1
I'm going to do this on my 98 M3 w/ 24lb (4 point) (Bosch cobra) injectors. Will need a tune obviously, but should be a lot of fun.
You had me at “just over 100 dollars”. lmao
This video is fantastic, thank you!!! Do you have any videos documenting your oil cooler, it's sick 👍
Thanks! I do have a few videos of the oil cooler setup on the channel.
Great Video! Thank you from Germany! 👍🏻😊
Thanks for your time and efforts
Amazing video!
thanks man!
just ordered this kit. hopefully they are still shipping
Good morning Quinn awesome video are you still going to do more of your Sunday drive video’s buddy 🤔😃👍
Good Video, bro. Ty.
Great video,thanks you for the info 👌👍
Thanks!
I’m almost complete with this mod and I know a tune is ideal to get the most out of this, but I’m reading bigger injectors are also needed even without cams? M3NACE, I’m also in SoCal and how do you pass smog? Also, watching you and Treats on the Streets videos have really inspired me to start working on my M3 again.
Nice video! Can you make a material list for this convertion? I have the same engine
just done doing that, thanks for this videp, It helped me a lot to keep some things in mind. had a few challenges with the vacuum routing but it was all sorted with patience lol cool video! now looking back at this, I plugged my air temp sensor to conector to the temp sensor in the manifold instead of drilling a hole in the intake boot and reusing my M52 temp sensor, What kind of problem would that cause?
as far as I know, they are not compatible. meaning you will have false air temp readings, which can cause lean/rich and other fuel trim issues.
Great video! I think it's throttle "heating" not cooling. The water lines were developed to keep the TB from freezing. AFAIK
thanks! I read that, i think i recall something about heating the throttle body on warm up to make it get up to temp quicker as well.
Once fitted will the car run with the visa u plugged ect?
Thanks
I’ve watched this video over and over, I did the whole install except I did it over again maybe 6 times lol, I’m having issues and I double checked everything
Injector O rings (some had to replace, ok now)
IACV clean (still having idle issues)
I disconnect the MAF the car keeps idling but very rough, with maf connected it stalls
I checked all vac lines no leaks, any suggestions? Maybe my chipped ecu with burble tune messes with it?
Excellent tuto bro
Where can I find the silicone hose?
Hola yo hice esta conversión en un BMW M52 y no puedo regular el talento se acelera solo, algún consejo?
I need that conversion kits for my e46 330 i
that big hole under the m50 mani where you plugged it up with the new hose from the kit, does that hole plug in the to the ICV originally? So if I were doing a oil catch can, I would just need to hose there to the icv?
Would you encounter any problem if you would just swapped the m52 air intake sensor on the m50?
Hello!
At 14:37 you say we will have to connect the line that came from the secondary air pump, and that it would be a part of the 'T'.
Does this mean nothing should be connected to the secondary air pump?
Any help is appreciated!
What if I don’t have a sap? I have it tuned out in my dme along with ews and a higher rev limiter, all I connected was my icv, iat, and fpr hose I don’t have a catch can, and would like to vent to atmosphere even if that means I get oil in my bay or something but does that mean I just have to cap my dipstick vent tube?
Hey what’s up I’m just doing my intake manifold swap now. What should I replace while the manifold is removed. Any vacuum lines or any coolant lines ?
Does anyone use this at a e30 m52 conversion with the dipstick at the front side? Will this fit??
Greets from Germany. Nice Video. Good work!
I got a question! My 1999 e36 323i (m52) has a m50 intake manifold from the previous owner, and I believe the “P0142” code and check engine light are from a unplugged sensor or something. The SAP is still installed and I’m not 100% why it has a check engine light but I need to fix it ASAP because my inspection is expiring
hi, have you measured it on a dyno, how much horsepower difference did you get, or someone who has changed the intake can also tell, because I also drive a 320 and wonder if it is worth it
Would we just block off the third part of the hose if we have a CCV delete
M3nace, Question - i discovered that my recently purchased 98 M3 already have the M50 swap. I couldn't tell at first because the connection of hoses and IAC value is completely different than your's. The previous owner did not use the kit.
1. The IAC value is plugged directly onto the M50 manifold. looks like it's drilled in, same location as stock.
2. The "T" plug in your video is left open. so i have no clue where those two hoses are plugged into.
3. The IAT sensor is no where to be found. its not plug on the intake boot or the M50's IAC location. That hole is also left opened/unplugged.
Question - it seems i have two open holes on my M50 manifold, the IAC plug hole and the "T" plug location. Should i plug these 2 holes? I am NOT getting any check engine light or lean codes. i am afraid it's sucking in dirty air.
Thank you,
Is there any benefits to port matching, there’s a few kits that have adapters that offer port matching
How similar would this conversion kit work with a 99 323i? I think that’s the m52tub25 engine
Amigo dónde consigo ese caño azul para la adaptación ??
does this work on m52tub25?
Is your vanos plugged into the fuel rail? Mine is on a 99 323is
Hey did you bypass the vaccum tank the check valve was connected to on the obd2 manifold ? I know it’s for the exhaust flap apparently I’m just curious doing mines spend all day trying to figure out what vaccum hose went to it and it’s purpose let me know just so I can be satisfied lol
nope, it is still in place. it goes from the hard vacuum line off the vanos, up to the solenoid between intake runners 1 & 2, then to the check valve, then the manifold T line assembly in this video.
👍👍
Were do I get the kit I have e46 330i I wanna swap
Quinn what’s the pros and cons on throttlebody cooling on the BMW 🤔
pro is that the engine warms up faster, con is that the cooling system is more complex, and when the motor is hot the air charge is hotter, which means less power. I read someone did the math on it and they gained almost 1/2 a HP with the coolant delete.
Question regarding TUNING ( i'm a newbie here)? M3nace mentioned using an aftermarket tune such as DINAN or RKTune. I looked them up and these are tunes that can be ordered pre-programmed with your list mod options. Sounds like all i need to do is "flash" my DME with a laptop with the tune and be done with. Should i also have my car DYNO tune after my car has been flashed with the aftermarket software? Thank you in advance.
I personally run a Kassel Performance tune on all my cars, great tune at a solid price. that said, the M50 swap can be run on a stock tune, and an aftermarket tune will only increase the performance, but there are gains to be had with a stock tune. a Dyno tune might be a little overkill for a mod this small, but it can be done and im sure it will yeild more power than a shelf tune.
@@M3NACE thank you
where the catch can is plugged to ?
why does the swap not work on m52tu? im pretty sure ive seen someone do it on m52tu
Fuck!! I love you!! your attention to detail is far by one of the best ! Best fucking video! On the install ever !!
You relocated the air temp sensor but couldn't you also buy the lower temp one and keep it in the same place to accomplish the same task?
you could, you would need to fit it into the manifold. i prefer the intake boot because its quick, simple and easy.
Whats the part at 10:23? Is it the idle control valve connector?
I feel like there are not many videos on the s52, like yours looks like the m52 right? But I was wondering if anyone knew if the process is the same with a s52 engine, only main differences I is think they have are intake and exhaust sizes compare to m50/s50 as well. Also the aluminum vs iron, but also its double vanos, anyone have any tips? I'd really appreciate it. Happy Thanksgiving
This is an S52B32. are you referring to the S50B32 or E46 M52/M54?
So when kassel flashed my ecu,one of the things it listed as done was a "SAP Delete." So since he technically wrote that whole system out,do I need to hook up that solenoid?
i like to have it on just so the car looks complete, but no. I have the vacuum hose deleted as well.
Good,my dipstick vent tube broke...now stuck trying to replace it.UGH I JUST WANT MY CAR BACK
Great video man. Does this conversion work for e36 323is?
Yes
Can you provide a link to your kit? I found a BimmerWorld kit but doesn’t seem like yours really. The new tube for the swap is different.
@@cornertaken6627 m50manifold.com my G
BONJOUR ou as tu acheté la durite bleu pour le swap stp?
Might be a stupid question but what are the hoses coming out of the bumper? I’ve seen them in other car pages but I still have no idea what they are for 🥲
They are for oil cooling.
So when I go to start it,if I messed up somewhere and now have a vaccum leak will I throw a code? If so will that code then have to be cleared to turn off my engine light reguardless if I fix the leak?
most vacuum leaks will throw a code, if your car is OBD2 the code will not self clear and will need to be cleared with a scanner. it it's obd1, then the code will self clear when the problem is fixed or the battery is disconnected.
Cant i just use my m50 injectors?
Seems like my fuel rail is very close to the back side of the manifold. Did you have a problem with the fuel lines hitting the manifold ?
are you running the stock M52/S52 fuel rail? how did you trim the manifold for fitment?
What part is at 10:22? I don’t have that piece on my M50 manifold
Will this fit a 1999 528i?
Does it work with M52B20?
Aww I have a m52tu :( i might swap it with a m50b25
Any “while you’re in here” type repairs you recommend when doing this?
heater hoses are a good one, vacuum lines that are worn, cam and crank sensor and starter if you really want to get into it, knock sensors if they are degreading
@@M3NACE Awesome, thanks man. I'll add those to the list!
❤❤❤
I did this swap with Schrick cams, Porsche 3.5 MAF w/turner harness. I’ve take the car to 2 shops and no one seems to be able to figure out why my car cannot good an idle. It ran perfect before the swap. No CEL. Everything under the hood is brand new. One thing I noticed in your video that I don’t think we did - the IAT in the intake boot. Is that necessary? We def dis not do that. Lots of money dumped into this car. It’s been a year long project and since I’ve had it back. Really want to get this figured out. Please help! Thank you!!
Cannot hold an idle*
Did you manage to get an answer? I think I'm having the same issue
If I loop the throttle body cooling into itself,will I have to bleed the entire cooling system? I'm currently wrapping up my manual swap(no choice,blown trans)and intake swap(since I'm getting the ecu flashed). Due to financial issues it's taken a long time. If I can eliminate them without adding another potential extensive job onto the list I will.
If your quick you can just top off the coolant and youll be fine, if you leave the hose off for 3 hours and it drains the head then yeah youll have to bleed it.
@@M3NACE ugh. It's lookin like I might be able to make it fit. Now my biggest issue is my dad helped me dismantle,now he's not here and I have no idea where he put half my shit lol.
And thanx for all ur help on these videos. I sure hope u get money per rewatch,cuz if so I personally prob made u enough for ur next project car lol
@@TechTokOffical thanks man! best of luck with your swap!
*Me watching with a m50 motor e36
“This is a great tutorial”
Hey man I must have got some lines confused. The SAP unit has a line that runs to a "vacuum unit" canister. Can I delete that whole canister since I'm re running those sap lines elsewhere? Also I have already deleted my SAP
Where is the canister located? The SAP system doesnt have a canister, might be refering to the charcoal canister for the evap system
Hey M3nace, have you ever broken a valve spring? I just did the m50 manifold swap on m52 and 200 miles later I lost compression on cylinder 4. Are these springs known to fail? Please help
Unrelated issue, unless it burned a valve. Ive seen a few valve springs break and crack, but the motors still ran fine and had good compression. Not saying it cant happen, i just havent seen it. Do a leakdown test and figure out where the compression is leaking then diagnose from there!
do you use the stock manifold brace/brackets?
you can, i throw them in the trash though, been running my cars without them for 5 or 6 years, never had a problem. just makes the manifold a PITA to remove and install.
My manifold swap was done by a previous owner and the icv isn’t mounted anywhere, it’s just hanging by a hose. I haven’t noticed any serious issues but could this be affecting anything?
It might be the bimmer world kit
what kit is this ?
Is everything included with the kit. On the website, it shows the throttle body seal as a seperate part from the kit. What about the Intake manifold gaskets? Are thise included or bkught seperately
Everything except the manifold itself is included. Throttle body gasket, manifold gaskets, ect.
@@M3NACE Thanks! Just picked up my manifold for $20 lol
@@LanOsb133 nice man! Good luck with the swap?
@@M3NACE thanks, just did a B28 swap, but the harness is bad. Figured if Im already pulling the intake manifold to replace the harness theres no way Im putting the M52 manifold back on.
Why we can not use the injector and rail from M50 to fit?
Different fuel line, regulator setup.
Where did he get that blue hose from, ive been lookin and cant find it anywhere
M50manifold.com
Wait so is there nothing that plugs into the charcoal canister ?
The purge solenoid is already connected to the canister, the solenoid gets plugged into the big T fitting.
Is my front support bracket from my S52 able to connect to and support the M50 manifold? Or do I need a front support bracket from an M50 block?
The manifold support brackets? I throw them in the trash, unneeded and makes servicing a PITA. ran without them for 8 years with no problems.
@@M3NACE I know lol. I might use the front one. Do you know if the s52 bracket will work?
@@bluesubie02 im not sure my friend
I need your help i did this swap to my m52tu which comes with cable Throttle body and once installed in the M50 mani.. the cable does not go along with the Throttle body. Any ideas on what can i do?
does not fit or is too short?
@@M3NACE well it is in range but theres no way to set it in place.. my car is a 2000 323ci i might have to get creative and come up with a solution to set it in place.
the m50 mani i bouught has the evap from the mani block off w rtv. what do i do with it if its blocked? Help, first time
I would clean it out. if not, replace it.
@@M3NACE hey again its me. for the m54 has the brake booster valve that connects to the intake boot. can u delete that or where can i re route it? can i route it to the SAP since i deleted it?
I have a m50 motor and intake how do I delete the air box and put a cold air filter on ? Cause there is a sensor that goes in the stock air filter box.
what sensor is in there? I'd swap it and ditch the sensor, see what happens lol
@@M3NACE czcams.com/video/5KyBdDqcBq8/video.html
If you watch this video it's the sensor next to the mass airflow meter.
King Ryan Could it be a intake temp sensor?
@@oliverlarsen6768 hi Oliver I don't know the name of the sensor, but i didn't get a chance to check it out due to building up my pickup truck
@King Ryan looks like that's not a sensor, just little pieces auxiliary with coolant water circulate my gues to warm the air inside the box when winter season CMIW.
@M3NACE thats excellent video
what do you do if you have done a ccv/pvc delete?
Emon Safdari I would like more information on this CCV delete as I have a catch can installed on my M52 motor with M50 manifold but the PO did not install catch can plumbing correct. I have a lot of suction from oil cap and dipstick
thinking about doing an Intake manifold swap on my E46 225ci to a 330ci. Any tips? 2.5 - 3.0
I honestly dont know man, i dont have an E46. are the manifolds different? I would assume it would be a pretty direct swap
I think it's SLIGHTLY bigger but the 3.0 tb is larger than the 2.5 again just by a little I think they sell adapter bracket for it
Also I don't need to relocate the temp sensor if I brought the one from bimmer world?
i dont know how the bimmer world adapotor kit works but if it has a port for it then no.
It's just a modified air temp sensor that is made to replace the one in the intake. I think it's just a threaded version of what u have there so it's a seamless transition
Where did you get the blue hose for the PCV?
m50manifold.com
I forgot to mark the fuel lines was wondering how to figure out which one goes where.
plug them in and hope for the best, if it doesnt run swap them lol
refer to the video at 3:57 it should give you a good reference which fuel line goes where.
was it worth it? do u feel the rwhp increase?
oh yeah. the top end really changes on these motors after the swap. my car skirts the 2-3 shift when it did not before.
@@M3NACE and how about the low range? i've heard it sacrifices some power there on low rpm, stil cant make my mind if i need this mod for my daily where i almost dont go over 3.5k rpm
@@dawidkorzeniowski6100 if you dont tune it you will loose some low end and midrange torque. with a tune there is no torque loss and even more power gains. Im running a Kassel performance tune and there is no torque loss. my car does see high rpm almost everytime i drive it, and it is a nice mod to have on a daily.
No point using a torque wrench if you're still gonna over torque the bolts.
I wanna see your car and performance after DIY.
like before and after pulls?
@@M3NACE yes could you please.?
What if I deleted my secondary air pump? Do I just cap off that upper nipple on the solenoid?
Yes
@@M3NACE the fact that this answer is all I needed to finish up and you replied ASAP just made me an even bigger fan. Thanks homie.
@@HackMassacre i gotchu man!
Can I use m50 air temperature sensor ? Thank you
no. you need to run the OBD2 sensor.
@@M3NACE
Hmmm..
Euro M3 E36 3.0 S50 B30 ( Bosch DME ) and M3 E36 3.2 Euro S50B32 ( Siemens DME ) used the same sensor.
@@pawetrocki5781 they might, but neither of those engines are M50's or M52's.
How did the car feel after adding this mod?
Shes a screamer. Total difference in top end power. Above 4k its a totally different car.
at 15:25 if you do a secondary air pump delete, do you just run the evap line to the manifold, i would assume so
yes, or just ditch the T fitting and run the FPR straight to manifold.
does it work with m54 ?
apparently some guys run these on M54, im not sure exactly what other changes need to be made for that motor.
I cant find a kit for this. I got the manifold but i cant find a kit with everything else. Hit me with that link?
