Hey guys! Before you start on disassembling the block, wait until we come out with part 2... we’ve had an issue with the piston/rod compatibility that we’ll update asap
Hey.... I love your videos and I'm currently watching the s52 e30 swap. I wanted to know if I can swap the é34 suspension,engine and trans into a 1975 Peugeot 504 shell
Wow this brings back memories! Back in 1998 I built a stroker with no internet info. Just word of mouth from car clubs. I used a EURO 323i head, drilled and tapped the cam for a cap and rotor, on an ETA bottom end, 2.5 intake. No custom engine management except for custom chips, so I used low ohm injectors from a euro M30 and a custom chip from a popular tuner back in the day. I think it was a Mark D. EAT custom chip. I still have this motor sitting in the back of the garage on an engine stand.... Car was wrecked with only 1000 miles on the setup.... 1BADETA rip
Andreas D’Greek I am looking to get a cheap inline 6 and I’m am thinking of going bmw and I have been worrying about computers and stuff for the engine could I get some pointers or tips
I know everyone is asking for part two, and I'm going to be no different. But I'd like to qualify my request by saying, I have a 1986 325e that runs great, but has a wiring harness / sensor issue that has become so frustrating that I bought a 1988 325i just to make a stroker between the two and eliminate the ETA wiring harness. Granted I could look elsewhere for build information, but you made this video so clear and concise that I'm not so patiently waiting for part two.
@@DENVERBEERANDOIL Already watched it and stoked to see you guys put out the additional video on different "I" pistons as well. Only question I have is, will any eta pistons work or super eta pistons only? Thanks again for doing the work and giving out the info for free 🤘
I’m gonna have Will comment on this, though my understanding is, super eta & “I” pistons after the production date (which I forgot) are the ones that will work... another option for a ‘low compression’ boost build would be retaining the ‘e’ or 2.7 pistons
Dear god man, where has this content been when searching TH-cam for the last year? These vids are exactly what I was looking for and needed thanks so much for all the information!
hey here from denmark. nice to see you boys know so much about 80s bmw.s one of the best cars back then really enjoy seeing the passion you have for the old bmw.s
I have subscribed . I need all this info . I will be tearing down my m20 b25 as I am low on compression on cylinders 4 and 5 . I may just get more horse power by following your videos . Top bloke 👏👍
Great work boys I'll be slapping a m20b25 into my 87 325e and your videos are gunna save me hours of reading constantly off topic bickering in the forums ! Cheers from Canada 🤙🍻
Watch this for the first time but i really like it! You should have more subscribers! Im doing a revision to my M20 head and your information helps a lot!
I have a really mint E30 convertible with a blown automatic. I want to swap in the Getreg 260 but dont have the time or the working space. You should do a series on Swapping in a manual and tuning the engine on my car.... you keep all the ad revenue from the videos. Sounds great to me😆 I just subscribed and liked this video by the way. Very happy youtube algorithm worked!
Awesome! We are glad it worked too! Already have a video on manual swapping if you look in our DIY playlist. As far as tuning is concerned , going straight to a megasquirt is optimal or talking to SSSquid tuning about a custom chip to suit your engine mods and driving style would be another good route! Hope this helps
Thanks for this video!!!! I have had a 2.7 stroker in my shop but gave it away in a trade years ago. I now have a 2.7 block and all the lower end bits. Finally located an 885 head from good friend in Canada that I completely rebuilt. I reused the rods from the eta but swapped in the pistons from the other M20 I had to match up the top profile and not have any valve/piston slap. My complication was I have a M20B20 as the donor for the intake mainfold that is aspirated...that's right: SOLEX 4 bbl carb. Looking forward to parts compatibility, watch to watch for, etc. the Piston Warning is totally worth watching!!!
guys prior to taking the rods out. a stamp on the bottom of the caps can be done. a simple number stamp or many little marks to number them is fine. Remove one by one and place the cap back on the rod after dissembled. It really helps out to put the same rod into the same cylinder and it could keep the machine shop from scratching their heads. You want as little confusion when taking motors to machine shops cause that'll cost you extra dollars.
If there is too much wear in your cylinder you might have to have it bored over and would require new pistons. Have the bore sizes checked first, if boring is required, purchase the over sized pistons first before u have it bored. You want you cylinders honed to the spec required for those pistons and sometimes its best to double check the sizes of the pistons once you get them. If the tolerance is fine, have a simple hone done to give u a cross hatched pattern for oil retention and careful with the sleeves on the pistons, do not use abrasives.
also: about the reuse of the crank bearings: I understand where this is coming from. The cost of the bearings is not the issue. The issue is that the crank bolts are expensive as hell. I'm talking about 9 bucks per bolt. Also, when your buddy measured the taper, he should measure in the other direction (the direction of the rod angle. He did it the other way).
High quality video, pleasant to watch! Even higher level of detail, if I had a BMW I would start this project straight away. Bumped into your channel recently, been watching ever since.
i know you say dont use the e28 m20b27, but didnt the 88 e28 get the Super eta like the 88 325e? those have an 885 head stock on a 2.7 bottom end with higher comp ratio than the normal 87 and older etas if im not mistaken, one build id like to see/ do is a 2.8 m52 crank in an m20, 135mm rods from the b28 and a set of custom pistons (with a 5mm higher wrist pin) that setup with triple webers still holds the unofficial highest N/A hp for an m20, i think it was 250kw to the wheels... check out morerevsm3's videos
Very interesting... I have never heard of such a thing. If it's possible I would love to see pictures... Google search yielded no luck. @mile_high_euros on insta -will
Before M3 bmw was developing a 2.3 liters engine to participate in rally with the e30's ,so they create this engine from 1984 to 1986 is l L JECTRONIC first sistem whit injectors before that was K JECTRONIC with injection lines like diesel ,they Winn some rally whit this engine but in late 1987 they built the M3 e30 whit 4 cilinder 2.3 liter M power an you know the rest of the story so the m20 23 is de dinosaurios of M3 hehe I will send some pictures ,the engine is in a wooden box right now because some Bodie texting hit the side of the car end bent the Bodie it was a beautiful Bahama beige e 30 I will send you some pictures of this ,thanks for the videos that you guys published they helped me a lot whit my 1989 325i I'm working now .
I’m doing a 2.7 block 2.5 head. I got it running but my bearing journals on my crank went to shit 255k. I got a crank donor. And I going to use my stock rods and pistons and I getting new everything else. I have an Alpina b2.7 chip
Your knowledge is incredible. I'm new to the m20 world and have a lot to learn. The engine I have is similar idea to your budget build with the block from one, the head etc from another. My block has different water holes and also had the distributor to run the oil pump. It only used it for the oil pump as it had the distributer mounted direct to the cam the same as your. My oil pump distributor has a plug into it so i'm assuming this is to timing or revs? Keep it up, enjoying your 'series'.
Another great video, gonna start sharing these on the fb groups. I love how long the video is and how in depth you go with info. Not gonna lie this gives me the urge to go get a 528e to head swap and turbo lol. Got two too many boosted projects already though haha. (m42 e30, m52 e36)
Mad levels of info details and real knowledge! Just remembered what I wanted to ask you about the s38b38 when you do that video. 1) True that the timing chain tensioner from an S50 is an upgrade for the S38B38? 2) The stock power steering pump in the e34 m5 uses a different liquid (pentosin) which conects to the SLS suspension system - can you use a different PS pump from like an M30 that uses stock PS liquid or you can just plug the holes in the pentosin pump ? Or like make a closed loop for the PS pump? Asking to remove the stock suspension system and get new coilovers without worring about the power steering pump. 3) Maybe show please how to do a valve adjustment procedure on the S38b38 and the throttle body sync 4) Is is true that the stock exhaust headers on the s38b38 are made from inconel? 5) The famous oil question - what would you run on them 6) Your paypal adress please so I can say thank you with some beers :)
Thanks so much for the support! I screen shotted all your questions so I can specifically address them in the upcoming video! I'll make sure we go into detail and answer all of that! @willmurdock on venmo if you feel so obliged haha many thanks!!

Thanks for this. I need to pull my engine out after overheating it a few times - my fan was getting caught on the rad (which moved after a shunt) when it warmed up. I was told to run just water as coolant (as it's better for cooling) by someone a while back... yeah... I now know it's total horseshit and my coolant was brown and disgusting when it blew a hose!!
After completeing the Conversion / Frankenstein with 2.7 bottom and 2.5 top what were the HP #'s you saw were they in line with your predictions in the beginning of the build and if so can you share them with me
I learned something new every day between those two engine. I’ll definitely do this to my e28 brah!🏄🤙🏻BTW I’ll tell my grandma to subscribe this TB channel brah!🏄🤙🏻
If you have the 88 eta. The difference between the 2.5 and 2.7 are even smaller. The 88 eta or SETA is damn near a 2.5 with a longer stroke, smaller cam, single springs. I have a SETA with a bimmerhead 885 head(split 280/274 cam, port n polished, HD rocker arms, double valve springs) and a stock bottom end. Because the SETA already has 885 head from the factory the compression ratio does not change when you upgrade.
I've done the same, 88 super ETA block, I head, I intake manifold, throttle body, m30 intake, arp studs, 19lbs injectors and a squid tuning chip. Is there anything I'm missing in my recipe that could help me out with some power
Was wondering what you think of this: I have an M52B28 crank. Was thinking of using this with b25 pistons (may need to clearance) and b27 (eta) conrods. I have an 886 intake and cylinder head . . . and some nice headers along with megasquirt and a waste spark setup. I have all of this stuff. Might as well have some fun with it. Would be going into my 86 325es with a getrag 260. Thanks DBO dudes!
I have a e28 2.7 supereta motor in my 325 e30, im looking to swap on a 885 head onto this however u stated that the e28 motor is not good for this. Would i still see horsepower gains if i carry through with this swap?
Awesome video!! I'm looking to swap my 84 ETA or build a stroker. When can we expect to see the rest of the build. Also looking for a regular budget build. Mahalo!
I have an "885" Head off a M20B25 that I got in a trade deal. The known problem is that the engine was destroyed in a timing belt failure. As you know this will do a job on valves, pistons, cylinder walls, etc. My question is would it be worth trying to salvage this head? Replace guides, seals, and the two valves that "broke" or would you say I have a large aluminum boat anchor? I wouldn't mind being able to save the head and build a stroker but I'm not sure if I should put any money into it as is. Thanks for sharing your knowledge.
I would say take it to a machine shop and see what they think. I would assume you would be somewhere around $600 to get it right and that would be worth it in my opinion.
Dudes luv your channel Happy b- day America is part 2coming?dum question got a 88 seta valve springs Lil worn out can i put the double springs in or stay with single? 885 head and all stock what do ya think? Dudes rock on!!
I have an ‘87 super eta with the stock domed pistons and rods. I also have an 885 head from a donor 325i, rebuilt.. Would the timing change for this Frankenstein swap? I’m having issues starting it up. :(. Any tips would help! Your vids are really helpful and unique compared to all of these other channels ! Thanks for your effort in showing us every detail and info you have
Swapping a M20B27 into 84 318i not so hectic ? I have a a complete motor with ecu and wiring harness and accessories. But what other parts would I need for this swap?
This is great since I’m doing this very build soon! Side note have you ever come across an E30 that was running great but after say a clutch job everything is back together and the car only cranks? Has no fuel or spark... I’ve fixed this issue years ago on one friends E30 but now i have another friend that it has this very issue and i know its electrical but figured id ask if there was a common mistake people tend to make. Thanks for all the content!
Additionally, if he didn't put the original flywheel in and the replacement one didn't have the pin on the flywheel for the crank pickup, it won't run.
As a heads up, before you start on disassembling the block, wait until we come out with part 2... we’ve had an issue with the piston/rod compatibility that we’ll update in part two
Hello, i have a little cuestion here, what is the final compression radius with which the engine would be at the end, putting on the 885 head in a 2.7 eta block??? Greetings from Costa Rica
Damn. I have an e28 and I was hoping I could just swap a b25 head on along with the electronics, get it running on that, boost it, and go along my merry way. Now I know it goes much deeper than that.
@@divingboardlord well additional oiling is always a good idea. Having said that, if you are careful to avoid cylinder wash down, have a good tune, and avoid sustained high RPM (in boost) driving, you should be completely fine. The issue is with the oil control rings and their ability to keep the cylinder lubricated/cool under sustained RPM. This can be combated using the techniques above and possibly some Lucas oil stabilizer to help keep the oil on the rings and cylinder walls
New subscriber so glad I found you guys! Thanks for the videos. I’m currently debating on whether to rebuild my m20b27 or just swap it for a b25. What would you do if you were on a budget? Also a side note, does this stroker build work on a b27 that’s not a “super eta”?
Yes this is essentially how to build your own super ETA on steroids! We didn't use a super ETA as differentiated by the pistons. Super etas have proprietary pistons and intake manifold. I would highly recommend doing this exact build but spending the extra $150 on bearings and arp rod bolts! Hope this helps. -will
"Be very careful when removing the pistons." Proceeds to smash piston with a breaker bar and drop it on the ground. "Don't do that, get yourself some friends" I laughed so damn hard. Love you guys!
We have a videos of how to remove them, swapping them into e30s, and talking about the different versions. We are currently in the process of building 2 different m5x based engines as well, but progress is slow

If you have the 88 eta. The difference between the 2.5 and 2.7 are even smaller. The 88 eta or SETA is damn near a 2.5 with a longer stroke, smaller cam, single springs. I have a SETA with a bimmerhead 885 head(split 280/274 cam, port n polished, HD rocker arms, double valve springs) and a stock bottom end. Because the SETA already has 885 head from the factory the compression ratio does not change when you upgrade.
I've done the same, 88 super ETA block, I head, I intake manifold, throttle body, m30 intake, arp studs, 19lbs injectors and a squid tuning chip. Is there anything I'm missing in my recipe that could help me out with some power
Was wondering what you think of this: I have an M52B28 crank. Was thinking of using this with b25 pistons (may need to clearance) and b27 (eta) conrods. I have an 886 intake and cylinder head . . . and some nice headers along with megasquirt and a waste spark setup. I have all of this stuff. Might as well have some fun with it.
Would be going into my 86 325es with a getrag 260. Thanks DBO dudes!
I have a e28 2.7 supereta motor in my 325 e30, im looking to swap on a 885 head onto this however u stated that the e28 motor is not good for this. Would i still see horsepower gains if i carry through with this swap?
Additionally all i have is the 885 head, i dont have the pulleys or alternator off the 2.5. Will this be an issue or is the super eta different?
You guys from Colorado?
Awesome video!! I'm looking to swap my 84 ETA or build a stroker. When can we expect to see the rest of the build. Also looking for a regular budget build. Mahalo!
Working to get part two filmed!
I opened a white claw to watch this
have you turbo'd the stroker with lowest compression before
I have an "885" Head off a M20B25 that I got in a trade deal. The known problem is that the engine was destroyed in a timing belt failure. As you know this will do a job on valves, pistons, cylinder walls, etc. My question is would it be worth trying to salvage this head? Replace guides, seals, and the two valves that "broke" or would you say I have a large aluminum boat anchor? I wouldn't mind being able to save the head and build a stroker but I'm not sure if I should put any money into it as is. Thanks for sharing your knowledge.
I would say take it to a machine shop and see what they think. I would assume you would be somewhere around $600 to get it right and that would be worth it in my opinion.
Do you guys sell already built strokers? Thanks.
Would you use the b27 manifold with a turbo stroker?
Negative. Definitely go with the 2.5 manifold. Only use the 2.7 manifold if you're doing 2.7i NA with 2.7pistons.
Aren’t those pistons the SETA pistons that you should be using with the “i” head??
Yes. If you can find them. We weren't able to Source them in time for the video
DBO those pistons you took out of the 2.7, those were super eta were they not? The one you dropped? Should you not have reused those instead?
Dudes luv your channel Happy b- day America is part 2coming?dum question got a 88 seta valve springs Lil worn out can i put the double springs in or stay with single? 885 head and all stock what do ya think? Dudes rock on!!
Can you use the m54 3l crank and rods in the m20 engine?
Witch rod and main bearing you recommend for a stroker?
respect 👌
Please counting this series!!!!
I have an ‘87 super eta with the stock domed pistons and rods. I also have an 885 head from a donor 325i, rebuilt.. Would the timing change for this Frankenstein swap? I’m having issues starting it up. :(. Any tips would help! Your vids are really helpful and unique compared to all of these other channels
! Thanks for your effort in showing us every detail and info you have
Thanks for the video, quick question would this pass smog in cali? Thanks
Subbed because I plan on doing this
Really love this type of content. Bought a 325 touring years ago and it had a 2.7 conversion, now wondering if they did the low comp version or not
Swapping a M20B27 into 84 318i not so hectic ? I have a a complete motor with ecu and wiring harness and accessories. But what other parts would I need for this swap?
This is great since I’m doing this very build soon!
Side note have you ever come across an E30 that was running great but after say a clutch job everything is back together and the car only cranks? Has no fuel or spark... I’ve fixed this issue years ago on one friends E30 but now i have another friend that it has this very issue and i know its electrical but figured id ask if there was a common mistake people tend to make. Thanks for all the content!
If it's an early model try switching the two crank sensor plugs around. Common problem, causes a no start condition.
Additionally, if he didn't put the original flywheel in and the replacement one didn't have the pin on the flywheel for the crank pickup, it won't run.
As a heads up, before you start on disassembling the block, wait until we come out with part 2... we’ve had an issue with the piston/rod compatibility that we’ll update in part two
DBO awesome! Thanks for the tips! And yeah i was planning to wait til you had the stroker series done before tackling it. Lol
LOVE YOUR CONTENT FULL OF VERY IMPORTANT INFORMATION , WHERE ARE YOU GUYS LOCATED/?
Denver, Colorado
Tops again. DBO for real
Hello, i have a little cuestion here, what is the final compression radius with which the engine would be at the end, putting on the 885 head in a 2.7 eta block??? Greetings from Costa Rica
Love it
Damn. I have an e28 and I was hoping I could just swap a b25 head on along with the electronics, get it running on that, boost it, and go along my merry way. Now I know it goes much deeper than that.
If you are going boost, and are ok with leaving the compression low, that is a perfectly good way to go.
@@DENVERBEERANDOIL How big of a deal is it that the oiling rings on the e28 pistons aren't as good? is it enough to cause reliability issues?
@@divingboardlord well additional oiling is always a good idea. Having said that, if you are careful to avoid cylinder wash down, have a good tune, and avoid sustained high RPM (in boost) driving, you should be completely fine. The issue is with the oil control rings and their ability to keep the cylinder lubricated/cool under sustained RPM. This can be combated using the techniques above and possibly some Lucas oil stabilizer to help keep the oil on the rings and cylinder walls
@@DENVERBEERANDOIL Thank you! definitely gives me something to think about.
شكرا استاذ
I wish to understand if you can fit the b2.7 crank on the b20 block and if you can how to do that
I dont have any first hand experience on the interchange options with the b20 block as we didnt get them in the US
M20 bmw 2002 build video idea
And where were the cold adult beverages?
Abstained for attention to detail haha
Instead of doing a conversion would I be able to use just the m20b27 to turbo it? Would it be better than doing it to the m20b25?
part 2?
man you remind me of Lebanese how they modify E30s the same thing what your talking about we also had the 2.8 in Lebanon
New subscriber so glad I found you guys! Thanks for the videos. I’m currently debating on whether to rebuild my m20b27 or just swap it for a b25. What would you do if you were on a budget? Also a side note, does this stroker build work on a b27 that’s not a “super eta”?
Yes this is essentially how to build your own super ETA on steroids! We didn't use a super ETA as differentiated by the pistons. Super etas have proprietary pistons and intake manifold. I would highly recommend doing this exact build but spending the extra $150 on bearings and arp rod bolts! Hope this helps.
-will
Definitely Will, thanks so much man!
"Be very careful when removing the pistons."
Proceeds to smash piston with a breaker bar and drop it on the ground.
"Don't do that, get yourself some friends"
I laughed so damn hard. Love you guys!
Do you have any videos on M50's?.
We have a videos of how to remove them, swapping them into e30s, and talking about the different versions. We are currently in the process of building 2 different m5x based engines as well, but progress is slow
Hello from Georgia (country).
I have a bmw e34 m20b20 whit m20b25 block. I'm wondering what needs to be changed for the speedometer to be digital How do you know b20 has the old speedometer numbers that are spinning
Hi , question what ecu should I use with this build I have 87 e30e bit do want the stroker build
I’d really like to see an m30 build with a bit of data and science behind it to show some truth about what power can be found NA
Can a 323i head be put on a 2.7 bottom end and have a high enough compression ratio to be worth while doing?
I don't have any experience with the 3.23i head
What Pistons would you use for a boost setup? I got a 89 325i with a m20b25 and i have another engine on the side (m20b27) from a 86 325e
Hi guys, need some help, I have built a m20 B25 engine for turbo application but I used pistons from an bmw 36 2.8, I haven't fitted the turbo on yet, I got the engine started and running but my spark plugs doesn't last long, it burns out within a week of running. What could be the problem. Thanks
