My BMW M42 44 Frankenstein Complete Build!!

[@jacoslabbert5928]

The sound, the grit and determination, passion, and that speech at the end 🔥

[@ssbb_builds2090]

Amazing, thank you for watching 🙌🏻

[@xaviersandrinedemay6396]

Yes! Thanks for that!

[@budha59]

SO excellent to find someone local to be doing this. Was at that race day and your car sounded amazing on the tygerberg straight. My next project is an M44 E36, so your information is invaluable.

[@ssbb_builds2090]

Thank you so much man 🙌🏻 Really appreciate it 💪🏻

[@MLC...]

Great job, making very good power and sounds awesome. Sounds Super Touring. Enjoyed the video a lot! Glad you did not take the lazy route with a turbocharger, then it is no longer in the spirit of 1990's touring car racing.

[@ssbb_builds2090]

Agreed, I would rather have less power but stay true to the spirit and ethos of that era…. Thanks for watching

[@jasondaniels205]

Amazing! A little birdie told me there was a m44/42 frankenstein in cape town recently and a video of it screaming down killarney...been on the hunt ever since. Great build and great insight for the m44/42 community👍

[@ssbb_builds2090]

Awesome bro! Well there are some epic upgrades coming to improve the reliability as I prep for next season. Hopefully I will be able to make a trip down to CPT next year again. Keep an eye on the channel for the M42/M44 Frankenstein V2.0 build... Thanks for your support!

7:19 , thats the dowel from where the upper/bottom intakes meet.. I had the exast same thing in cyl 2.. i was dailying and tracking the engine and found it 3 years after i rebuilt it :D

[@ssbb_builds2090]

Thanks for the feedback and thanks for watching 🙌🏻

Dude awesome job keeping me motivated man work ethic is next level

[@ssbb_builds2090]

Thank you so much 🙌🏻 Appreciate it 💪🏻

[@jangalaba4626]

this speaks so much to me right now. Since i am saving up and want to make something like the S42. Its going to be so long but i cant wait to see

[@ssbb_builds2090]

Fantastic man!!! Keep pushing💪🏻

[@tanzeelgamieldien3544]

what a video, I was excited when I saw it on my recommended, got even more excited when I heard the accent and realized you were in South Africa. I would love to chat to you in person about some of the nuances in the video.

[@ssbb_builds2090]

Great, thank you for watching! I will be at Zwartkops on the 13th & 14th Sep if you want to make a turn.

[@tanzeelgamieldien3544]

@ssbb_builds2090 what a pity, I would have definitely made the turn but I'm heading to Cape Town that weekend so I'll just miss you

[@loekfelten548]

Awesome project ! Respect !Love the car and I still remember seeing all those iron gates for protection of properties when visiting friends in Pretoria and Capetown. Stay safe 💪🏻👍🏼

[@ssbb_builds2090]

Thank you so much 🙌🏻

AWESOME video🎉 Thanks for sharing!

[@patrickveekay7115]

Good to find a project team mate! Doing the same here, fully built M42 turbo with ZF8HP gearbox. I want be able to get it as close to the BTCC cars from 1994 and 1995. 300 bhp with a bit of modern and very fast shifting!

[@ssbb_builds2090]

Great man, I think 300HP is very achievable with a turbo. But that sequential box are what dreams are made of 😍😍😍 Thanks for watching 💪🏻

[@patrickveekay7115]

@@ssbb_builds2090you’re very welcome, I opted for the M44B19 chain case because the M44 oil pump is bigger which is good for a turbo build. Are you on Instagram too?

[@martinlegodi9670]

Great work 👏🏾👏🏾👏🏾 I wish you were in JHB you were gonna rebuild my m44b19 in my e36 Motorsport!!!

[@martinlegodi9670]

I see towards the end of the video that you are not in cape town. I need to come see you regarding my m44 engine I am really impressed 👏🏾👏🏾👏🏾

Yes, I am in Pretoria.

[@ssbb_builds2090]

Glad you like it man! Got some cool upgrades coming!

[@robertfontaine3650]

The poor little unloved 318i. I bet those ITBs sound fantastic.

[@ssbb_builds2090]

They do, thanks for watching

[@Jlou21000]

Beautiful! Planning to do so in an M3 e30 replica build

[@ssbb_builds2090]

Fantastic! Sounds great💪🏻

[@rudyada33]

Awesome video. Well done on the build!! Are those aftermarket ITBs or from some other engine? Which ECU are you running?

[@ssbb_builds2090]

Thank you They are Toyota 20V 4AGE ITB’s. Silver top 43mm. They work perfectly 👌🏻 Running an ECU Masters Black ECU

[@qubek333]

I got it right, you use m50b25 pistons up to 85mm diameter. Why didn't you use a shaft with an M47d20 with 88mm stroke (1950cc) and a little bit modified N53b30 CH29.8mm pistons?

[@ssbb_builds2090]

That’s phase 2 of the build 🤫 Thanks for watching

[@robertfontaine3650]

ITBs and stock pulley may make acceleration a little binary / all or nothing, a modified pulley can give you more subtle control with pedal. No idea why you have built this but I am loving the video and the little engine. You didn't mention your cam specs. Was machine work cheaper than custom pistons in the end?

[@ssbb_builds2090]

Thanks for the information on the pulley, that is for future development, yes. I built this as a passion project and to compete in our local BMW club series which is lap time based rather than spec based. Cam specs are close to 276 deg with 10.8mm lift. Piston machining with off the shelf pistons was for sure cheaper than imported forged custom pistons. Not sure what it would be like in other countries but here in South Africa, it’s what is obtainable for the average Joe. Thanks for watching💪🏻

[@xaviersandrinedemay6396]

Are you wearing a HANS device? Could you pls make a video related to safety? From the research I've done: If you have a bucket seat you need a harness and so a HANS is absolutely necessay to avoid skull base fractures in front collisions. If you don't have HANS the only option is a reclinable seat and a regular 3 point seatbelt. If you have a full cage a bucket seat is essential and therefore so is the HANS. Please let us know 😊

[@ssbb_builds2090]

This is good information, thank you. I will look into it 🙌🏻

[@dann3401]

Awesome video. Was super happy to see this as there isnt much out there about the M42. I have a M42 stroker (2.1)that I built but it is still on the stand. Now that I watched your video, I'm going to pull it apart and check the compression. Want to pick your brain, hopefully you don't mind. Why did you back down from tdc when you checked the compression? I'm not familiar with that process. I also have a ECU Masters unit. How/why did you choose those throttle bodies? I have a set of E46 M3 throttle bodies, after seeing this I think I might scrap that and copy you with Toyota itb's. Also, are those factory BMW pistons? Why did you select those particular pistons? Thanks and Sorry for so many questions. Keep up the great work!!

[@ssbb_builds2090]

Thank you Dann, great questions. I backed the piston down between 3 & 10mm. It doeasnt really matter, as long as you take that number into account in the calculation. Below is a link to the calculator I made. You can use that. I chose the Toyota ITB' because A, their availability & B, their size. The M3 ITB's are 50mm. This is waay to large for what we can produce as a project build. The larger Dia ITB's slow down the air speed which then needs to speed up again as it enters the port. This reduces the overall mass flow & you dont get as much air into the combustion chamber resulting is losses midrange & at the top end. The pistons are BMW 325i M50 pistons. I chose these as I built my M52B30 motor using these. The gudgeon pin is located lower down on the piston which pushes the top of the piston higher up to +2mm above block height. I then had the pistons machined down to a profile I supplied them and pocketed the valve recesses. It took about 3 iterations to get the clearance between valve & piston dead on. This was by far the most time consuming part of the project. I will be doing some more upgrades for the season next year so lets see what we can do. Let me know if you need any additional information. docs.google.com/spreadsheets/d/1347_KmnUymKW3Fnt9dzKQ1hLiC4rcv3S/edit?usp=drive_link&ouid=104439853988076134193&rtpof=true&sd=true

[@Giuliano-o8b]

how did you solve the piston pin problem? the m42 has 22mm pins the m50 has 20mm. building new bushings machined from solid could create problems when hot

[@ssbb_builds2090]

Good question, thank you for asking. I went back & looked, I used an M52B25 piston. They also have 22mm pins. So no problem. Just lots of machining 😂😂😂

[@Giuliano-o8b]

just one last question. at minute 21.35 you can see that you use pistons with 85mm bore (84.97). in the european version the m52b25 engine uses 84mm pistons. what version are those you used? thanks for your help

[@robertfontaine3650]

If you go with solid lifters can you raise rpm higher yet?

[@ssbb_builds2090]

Hi, yes you can but the limitation will be the connecting rods and rod bolts. The solid lifters will give more reliability aswell.

[@MaFTB]

No leaking oil on a BMW?!?! 😱😱 Jk, nice build!!

[@ssbb_builds2090]

Thanks for watching 🙌🏻

[@armstrongauto246]

Why change from the M52b30?

[@ssbb_builds2090]

I changed because of a move to a different class in our BMW club. The M52b30 is still a mega engine ❤️

[@armstrongauto246]

​@@ssbb_builds2090 understood... lots more competition in under 2l classes

[@GarasiKomputer]

No one build frankenstein m43 motor ? 😢 I know m43 is hopeless but i just want to know more about this engine even it's not as fast as their siblings m42/44

[@ssbb_builds2090]

It would make sense if there was a series that ran that engine as a spec. Then yes, there M44 bottom end would be better. But you would always be limited by it being an 8valve, the port design etc.

whats the context of orie ntal tunes at the back ?💃

[@kamilsw3972]

Great movie! I watched with pleasure. I built a similar M44/M42 engine with ITB. I was mindful of the problem that can occur with oil pressure. I used assembly grease, maybe that would allow you to avoid the problem? kzbin.info/www/bejne/hH-TeH6ZpNSiqNUsi=JRskG_2dgSMqNSBG&t=196
