M50 Manifold Conversion DIY
Вставка
- Опубліковано 23 сер 2024
- In this video I prep the M50 manifold with the m50manifold.com conversion kit. There are a lot of videos, threads, blogs, etc that talk about this conversion but I didn't see to many that talked about some of the specifics including modification to the manifold to accommodate the OBD2 fuel rail as well as modifications to the existing OBD2 intake manifold brackets.
In regards to the kit, I am glad that I decided to use m50manifold.com conversion kit as fit and finish of the components was dead on. Also, the instructions you have access to with purchase of the kit are extremely thorough and useful as a reference. Overall, there is a reason why this kit has been around since 2008. It's definitely worth the money in my opinion.
The only thing I did not cover in this video was how I dealt with the IAT (intake air temperature sensor) and the idle air control valve hose. I did come up with solutions to both which I will cover in the installation video. I did however block off the threaded OBD1 IAT port using a standard issue M12x1.5mm oil drain plug and aluminum crush washer.

Great video man thank you. I was specifically looking for a video where someone shows the bracket and rail conversions and you're the ONLY one I found. Thank you again
Just stumbled upon your channel, and I must say im really impressed by the quality to your videos, concidering you have less than 100 subs. Great video btw, by far the best M50 manifold conversion tutorial out there! Keep it up :)
Thanks man! I appreciate it. Really only started uploading videos on this channel back in January so it will take some time to build up. Glad this video was informative and touched on the details. I may have an update to this video because I made some modifications to this kit that made installation even easier. Will drop that at a later date once the car is done. Also have a massive backlog of footage to edit.
@@GarethFoley No worries! Think you could cover connecting the vaccum hoses, and basically mounting the manifold on the engine as well? Then you would have everything from A to B ;)
@@mariusrisan I thunk I can do a video covering that as well. For the most part everything was pretty simple especially since I deleted secondary air and the vacuum reservoir for the exhaust. All I have now is the vacuum source for the fuel pressure regulator. However, you can pretty much T off of that as much as you want. I'll definitely put something together explaining it in greater detail.
Help great info, did you use the ICV from the m50 mini fold or the s52 manifold? Just curious cause I want to add headers and an intake manifold and want to do it right. Thank you
Hands down, best video on this project. Previous owner of my E36 just jammed the CCV and ICV under the manifold, which resulted in binding. Now I know how to fix it. Enjoyed The Paddock on Prime as well. Hope to see you guys back on the track soon.
Thank you. Glad you found the video useful. When I was looking into this I didn't find a whole lot of good info myself. Once I had the kit in hand it sort of made sense how it all went together. My recommendation instead of using the factory plastic manifold adapter for the ICV and PCV (11611738629) is to order a billet version from Reboot Engineering. It will never break and it's also fighter fitting than the factory piece. I have since changed that out on mine while I am doing other things with this car. Myself and the team included are looking forward to getting back on track for 2021. Hoping we'll have some big news on our plans for next year soon. 🤙
@@GarethFoley I have seen the Reboot adapter and other billet versions. None have the connector for the small for vacuum line like the OEM does. Where did you route it?
Thanks for the video. I bought a 328i slicktop and it has a bunch of mods done including m50 manifold... Gonna re-do this intake and try to get the car to start.
From watching your video, I'm piecing together a kit on my own (Brass T-piece, silicon hose pipes (1x90° & 2x135°), alu joiners, brackets, etc.)... hopefully it'll end up as perfect a fit, as yours :-)
Everything in ø22 mm
Thanks for an educating video :-)
Greetings from Denmark.
amazing video man best on youtube so far!
Thanks dude. I may be doing another one at some point with some different parts. Just need to get my hands on another M50 manifold.
@@GarethFoley im planing to upgrate to m50 on my e39 528i but i was wondering do i need to buy convertion kit or i can use parts from m52. 🤔
Great video.
Amazing video
Nice walkthrough, thanks for posting. I just did the m50 manifold swap myself, and experienced a vacuum leak. I believe it's coming from the open air temp sensor in the m50 manifold (which is just an empty threaded hole at this point). My m50 manifold didn't come with the m50 air temp sensor screwed in place. Curious to know how you sealed this hole? Did you throw a bolt in there? In the meantime, I just ordered the m50 air temp sensor and will just screw it in (unwired) to seal it up.
Very good tutorial
Glad you liked it.
Do we really need this convertion kit!? Also the oil separator!? In order to work ?!
Can this be added to an m54 engine? I have an 93 325i I have turned into a 1/3 mile dirt oval track car and need about 20hp over stock to stay up front. Headers should get me 5, so another 10-15 elsewhere would be perfect.
Hello,
I have a m52b20 and i want the m50 intake,
What should i buy with this conversion kit ? And
how did you get rid of the ASC body ?
Thanks you.
cool video! my kit will be arriving soon. What's that hose you used for the inlet throttle? is that aftermarket?
Yes that’s a mishimoto throttle hose.
I got a auto😢 will it be any different with the swap? Any things i gotta take care of before so i dont break anything ?
Best video for this Bravo!
Thank you. I appreciate it.
@@GarethFoley Thanks to you i actually found the kit i needed to do my conversion. Keep them coming
@@redyeti4x443 Nice. Good luck with the install. It definitely makes a difference once installed.
@@GarethFoley My E36 is a 99' so 3.2L and i ordered the 540i MAF so i can bring it to 3.5". Am i going to need the plug conversion so it can play along with OBD2? or will it be just plug and play? I ordered the plug anyway but,,,, you seem to be way more experienced so i ask.
@@GarethFoley This is the plug i bought in case i needed www.bimmerworld.com/3-5-OBD-I-HFM-Connector-Housing.html
I have an e30 s52 swap and I’d like to use the obd2 fuel rail, I’m just confused whether I need an fpr or it’s built in?
The fuel pressure regulator is not on an OBD2 fuel rail. On an OBD2 setup the fuel pressure regulator is located on something called the 3/2 control valve. #9 in the diagram linked here: bimmercat.com/bmw/en/search/selectCar/E36/Lim/BMW+M3+3%252E2/USA/16_0203

nice tutorial! does m50manifold still produce this kits currently? i'm looking to order one
Yes. They still offer it.

How long did it take to recieve your order?
@@danielsoong745 It only took a few days.
Have you ever thought of running the m50 obd1 fuel rail?
It's doable but I deemed it not to be worth it since I already had the existing OBD2 fuel rail. The slight modification needed to get the rail to fit the manifold plus the adapter brackets didn't make it worth sourcing the M50 fuel rail. At least not in my opinion.
wait are you that guy from fcp euro?
I'm for sure that guy from FCP Euro.
hi great video , I have to say JUST Use the flue rail from the M50 manifold and you won't have to do that work on the M52 flue rail . JUST Saying .
Yeah, I considered doing it. Only issue I ran into was finding an M50 fuel rail locally that wasn't completely disgusting. I also ran into a time crunch because I wanted the car done last year in time for a specific event so kind of made due with what I had. Naturally, the car wasn't finished in time anyway.
Were do I get the kit I’m trying that swap on my 330i zhp
This is not a direct swap for the M54 engine (what's equipped in your ZHP). The M54 uses a DISA valve in the intake manifold, utilizes a different crankcase ventilation system, throttle bodies, etc. Would not be a direct swap and would require a large amount of effort to retrofit with no tangible benefits. The intake manifold design on the M54 engine with the DISA valve actually provides the benefits of short runner length power with long runner torque. I would stick with what you have.
what about the intake air temp sensor?
I relocated it to the intake boot. I'm using a Mishimoto ASC delete boot which had two nipples on it which I use for the idle control valve and the intake air temp sensor.
@@GarethFoley do you have pictures or video on this relocation?
@@danielsoong745 You can see it briefly in this video at 11:44:
ua-cam.com/video/PpfqMGtxnZI/v-deo.html
Basically I used one port on the Mishimoto intake boot for the idle control valve hose and the other for the IAT sensor. Worked out pretty well.
