Your videos are great, I'm looking forward to seeing this car come to life. I'm working on my own swap right now and just piecing all the parts together before I put the new engine in. Merry Christmas!
If you’re going obd1 on s52 they sell an adapter that connects to the ecu and the other connects to the cluster for it to red the temp. that way you don’t have to drill into the block for the temp sensor
Where you blanked off the 2 hoses for the intake heater, could you not just run a hose between the 2 outlets, that would reduce the number of joints and also allow the water to flow around as it was initially intended
Yeah running a hose between would have worked absolutely fine. but the way it branches off the cooling system, coolant will only flow through it passively. It's totally unnecessary in my climate so I felt better with it blanked off.
@@jabaghstash7784 I vote look for the brown sensor which has been rethreaded to fit! I linked one I think in the description. Thats by far the easiest way forward. 😃
Check out the wiring guide video which will explain which wires to connect together between the E30 loom and the M52 engine loom. ua-cam.com/video/K_VaFcKwjlE/v-deo.html Although the E30 takes its speed signal from the differential and I think it goes straight to the cluster to appear as a speed on the dash. So if you are using the original diff and cluster it will work regardless of the engine.
What power steering did you use? Im swapping a M52 also and my car had no power steering. Im going to place the purle tag e46 power steering. Will those powerlines also fit then?
Hi Nico, the lines are perfect, you can buy them from here: bmconversions-uk.co.uk/ Contact them if you have any queries about fitment and I am sure they can provide clarity. They definitely do lines to fit a purple tag rack to an M52 swapped E30, whether they are exactly the same design I am not certain. 😁
For the coolant temp sensor. Did you connect the brown and violet wire to the black dme sensor? Wondering if the dme (ecu) will be able to read without all wires connected
I have left the brown/violet wire disconnected on the black E36 temp sensor. This along with the Brown/Yellow wire from the sensor is feeding only to the E36 cluster so shouldn't have any impact for the ECU if disconnected. I guess we will find out though, I'm not an expert on this. 😄
@@SPANNERRASH only reason I asked was bc I did a s52 swap on my e30 and had to ground the single wire brown sensor separately from the black dme sensor.. also running a power wire directly to the cluster through the c101 ..It is a bit of a pain taking everything back apart after having everything secured into place. But love the build 👍
@@cam5493 Interesting, someone else told me the ground to the brown sensor will be poor with the alu head. How did you go about adding an extra ground? I might have to do it myself.
@@SPANNERRASH my sensor was ran through a adapter in the upper radiator hose before the thermostat housing.. I soldered wire to the sensor itself, ran it through the harness into the cabin towards the one of the grounds on the back of the cluster .
Weird question but I was wondering what hardware you use on your build. As I've been replacing my non high stress areas with stainless steel In hopes they won't really rust
if you are talking about body work, you should never mix stainless and normal steel as the two mixed together have diffrent potential and will start corroding eachother. allways try to not mix metalls. they will accelarate the corrosion. same goes with bolts, dont use stainless on steel undercarraige. use 10.9 grade og 12.9. if i remember correctly the bently manual for bmw says what grade each bolt should be.
allso zinc coated bolts would techincally work as an anode and rust faster. they will turn dull gray and then suddenly become brown as dirt when the zinc wears off. best to do is match metalls and pain / wax it, coat it with a sealant.
and to top if off as i go, titanium harware is sweet for those no stress areas as dress up bolts. jdc titanium makes some nice ones. titanium or factory hardware is they way to go in my opinion. bmw has insanely good quality on their harware, same with audi hardware.
I try to use the original hardware wherever possible, some things are too far gone though and vastly over priced at the dealers, and for those I will use sensible quality alternatives from somewhere like spalding fasteners. We have another video about zinc plating which is something we do occasionally to revive original hardware. We have mixed success with it though so it needs revisiting. Looks like Alex has thought about this much more than I have, some sound advice there.
That would have been much better, but the trouble is its a different thread one M12 and the other M14 iirc. Otherwise I would have just screwed in the brown temperature sensor intro the hole for the throttle body heater port. 😃
Thank you so much for the detailed and well shot videos. I am doing an m50 swap into an '87 E30, and i literally took over the project from someone who was in over his head. My issue is that i received everything in boxes with zero reference point for orientation, but watching your videos has allowed me to stay in step with you! thanks again, if you are ever in Ohio, the first round is on me! p.s. check out my channel if you want to see some custom builds I've done. it's a weird mix of family videos and my projects,
Hey Mike, thank you for such a kind comment, I really appreciate that. I'm glad to discover the vids are proving useful for you with your M50 swap project. Sounds like an exciting build you'll get to finish off. I'll check out your channel, and if I'm ever across the pond I may take you up on that offer. Cheers! :D

Thanks so much Bill, Merry Christmas to you too! 🎄 I hope your engine swap goes smoothly and my vids are useful reference for you.
Fantastic job so far mate, it’s gonna be awesome when done. You should offer this service to other people when you’re done!!!
Cheers mate! That's very kind of you to say 👍
Dan at BM Conversions UK makes some excellent custom parts! 😎
Yep, they are OE quality if not better these new PAS lines. Really happy with them, and his custom routing is absolutely perfect. Top bloke.
You are fast becoming my fav UA-cam channel. I’m glad you didn’t detonate the bomb. 😂 I look forward to more vids
Haha thank you mate! It was a tense moment with those wire cutters. 😂
I believe the wire you connected to the starter sends a signal back to the ECU let it know it’s been commanded to crank.
Aha! Thanks for clearing that up, Kraig. I appreciate it. I really wasn't sure what it was for.

when you repin the plug use actual terminals crimped to the wires :)
For the C101 plug? Yeah thats my intention. I think I will do it properly after all. Apparently you can still get all the parts from BMW so why not! 😃
Great content man !! I have a question, Should i keep the black one in case of swapping an m42 from an e36 to e30?
Thanks! Hmm good question, I'm not even sure the M42 E36 has this black type, but the M44 likely does.
Can't hurt to hang onto it.
It came with a blck sensor, but not sure is it enough to swap it with the brown one , or should i drill a hole in the block which sounds scary lol .
@@jabaghstash7784 I vote look for the brown sensor which has been rethreaded to fit! I linked one I think in the description. Thats by far the easiest way forward. 😃
hello!
what have you done about the tachometer, how have you connected it to give you a signal?

why do you need 2 coolant sensors? Wouldn't the brown e30 one be sufficient?
one sensor reads the ecu and the other reads the cluster
@@cmack4life what extra function does the ecu provide? Isn’t the cluster enough?
@@yothisispaulvery important for the many ecu tables that rely on engine coolant temp to provide correct fueling and or ignition timing.
I believe the MS41 ECU needs coolant temperature for the engine to run properly. It's slightly more sophisticated than the E30's computer.

@@alexbakke8885 Interesting points there, thanks for sharing! I should probably pay more attention to what I use as well.
Are you sure of the order of your durations that go directly into the cash register? you don't have the opposite meaning?
bottom up and top down
I'm not sure I understand what you mean. Are you talking about timing on the engine? I checked all that earlier in the series and it appeared spot on.
i would have removed the hose connector from the head and put in the bolt that you unscrew for the dash temperature sensor. would been more tidy ;)
That would have been much better, but the trouble is its a different thread one M12 and the other M14 iirc. Otherwise I would have just screwed in the brown temperature sensor intro the hole for the throttle body heater port. 😃
