Euro M3 Compact Hi Folks, after a lot of thinking about a swap, reading Jim's manual 100 times and looking on the internet it is finally going to happen. I was originally looking for a damaged 328i from Germany, but they are very expensive. In Great Brittain (United Kingdom) are the car prices very low and I found a really interesting 1997 M3 3.2 Evolution Saloon with 6-speed manual. The only problem is the steering wheel, it's at the right side of the vehicle, stupid people... :biggrin: But I was in love, the biggest engine in my favorit Compact, so I bought the M3 and took it home. :tongue: This is a picture of my Compact; http://i138.photobucket.com/albums/q...s/IMG_0177.jpg http://i138.photobucket.com/albums/q...s/IMG_0124.jpg Here are some pictures of the M3, if the steering wheel was on the left... http://i138.photobucket.com/albums/q...anvoorkant.jpg http://i138.photobucket.com/albums/q...achterkant.jpg |
I allready took the engines out of the cars, placed the 4-cilinder on a palet and placed the M3 engine in my Compact. Here some pictures of the swap; http://i138.photobucket.com/albums/q...n/P1010051.jpg http://i138.photobucket.com/albums/q...n/M43eruit.jpg http://i138.photobucket.com/albums/q...0Sedan/S50.jpg http://i138.photobucket.com/albums/q...n/P1010047.jpg http://i138.photobucket.com/albums/q...n/P1010076.jpg http://i138.photobucket.com/albums/q...n/P1010082.jpg But, all of the issues starts here, the wiring of the engine. The DME unit is on the other side and the wires are to short to place the DME in the original place. The engine wiring loom is to small for all the wires too. I don't know how yet, but I think it's possible. How did you guy's fix the 'Auxilliary Fan' problem, the connection to the fan is the same, but it doesn't work ? What do I need to change to get it work properly for a 6-cilinder ? Thanx mates, JeroenB3 |
WOW! I must say your TI looks very nice! Excellent choice of wheels to compliment.. Was the M3 fully functional when you got it? |
Nice! Euro S50 swap I'd like to see how it turns out for you! Hopefully the swap goes smoothly for you! Keep us updated! |

looks like you hacked up a nice 4dr M3 to get it though, almost a pity.. :eek: As for your issues, your only option short of splicing longer wire onto everything is to get LHD engine harness from Ebay or a junkyard in your area. After the money it looks like you spent, that shouldn't be much of a problem. As for the aux fan, I just plugged mine into the same port. mine does not turn on until the temp gets above half anyways, which is vey rarely even without the engine driven fan.. but i do run a 80c thermostat with a 80/88c fan switch. Question though, how do you know it is not working if you can't wire up the engine to actually reach a temp to engage the fan???? The aux fan connection is part of the bodyharness IIRC, it will only turn on when the sensors tell the DME to tell the fan its needs to work. You'd need a running motor to find out if it works or not. |
Thanx guy's, I'll keep you up to date :wink: @ Philly, thank you for the information. Somebody told me the aux fan is different for 6-cilinders. The wiring in the M3 really is different from the Compact. But according to you it's just plug & play ? What's the normal thermostat temperature en switch, do I need to change it ? I also have to make the wiring for the extra coolant reservoir and the extra engine connection. Greets, Jeroen |
just get a LHD harness from a junkyard or Ebay man.... your asking for trouble otherwise, IMHO. Once you have the proper length wires, it should all plug and play without an issue. Its probably just a little confusing right now with everything being opposite to what it looks like. Too early to panic! ;) The aux fan is different for the 6cyls, but i presume you have one from your M3... it should work no problem. I can't recall off the top of my head the normal temp thermostart... 88'c I believe??... the only reason I run the lower temp thermo and switch is because I deleted my engine driven fan. If you are still going to run the engine fan, I would not worry about it. |
Hi Philly, thanx again ;) The engine harnass is fine, just the DME is on the other side, but that doesn't seem to be a big problem. The problem is the car harnass, my Ti is missing the following connections; Small 12 pin engine connector, Window washer resevoir sensor, Extra coolant resevoir sensor. I do have the M3 Aux. fan and the Ti has the same connection as the M3, but I understood the 6-cilinders have a different way of controlling it. The fusebox says the 6-cilinders and diesel versions use other fuses, it's not just for fun I suppose :D But it should work just fine, with the Ti connection? (2-speeds ?) |
My M3 Aux fan works just fine. No mods necessary. Make sure you install the front suspension from the M3 too.. |
Feel free to send me the M3 chassis when you're done with the swap:biggrin: |
Hi, I'm not going to use the M3 frontsuspension, I don't know the condition and I've got a Coil over set for the Compact, which does'nt fit with the M3 suspension. What do you need the M3 chassis for, there is nothing M3 about it :biggrin: I allready sold the bumpers, mirrors, interior and door stripes, the chassis is the same as every other E36 Saloon. It does have the suspension and complete rear axle. |

Im sure you can do without the low windshield washer light ;) Extra coolant resevoir? are your referring to the expansion tank?? As for the aux fan again, it will work just fine. Yesterday was hot here, and mine was kicking on and off all day long with no problems. And like I said, as long as you are going to run the engine fan as well... you'll have no issues in the cooling department. PS. if your front clip is still off your compact, now would be a good time to replace the thermostat and whatnot for piece of mind. Its slightly a PITA to do with everything in front of it, but takes 10 minutes without all that stuff in the way. |

I was wondering why the reservoir on the ti has a little indent in the side like something's supposed to fit in there :rolleyes: |
99% sure thats part of the body harness anyways now that I think about it. |
Thanx Philly, I will change the thermostat immediately :wink: Do you know the function of the small 'twist cap', wich our Ti's don't have ? And yes, I did mean the expansion tank sensor, it will probably just give a warning too, like the windshield washer :biggrin: I bought a Z3 M differential, but it doesn't fit offcourse, the input flanche has 4 bolts in stead off 6 and the output flanche is 94mm where the Ti is 80mm. I do have some 3.2 M3 shafts, but I don't know if it will fit. I am getting grazy because of all the problems, why didn't I just bought an Z3 M Coupé :biggrin: |
You can use the Z3 Diff with Z3 or E30 half shafts. Take the rear section of the TI drive shaft, and the front section of the M3 drive shaft and put them together. Have it balanced before installation. |
I don't know if the second part of the Ti drive-shaft fits the M3 drive-shaft. And will the Ti drive-shaft handle the 321hp ? This is a picture of the M3 drive-shaft, how can I sepparate the first and second part, there is no bolt :eek: http://static.bmwfans.info/images/epc/MTEzNDUyX3A=.png |
A small update with some pictures, I didn't make much progression, but I bougt a few extra toy's. Z3 M Differential (LSD 3.15) Z3 M Stabilizer rear Z3 3.0 Exhaust OEM http://i138.photobucket.com/albums/q...n/P1010122.jpg http://i138.photobucket.com/albums/q...n/P1010119.jpg I needed to move the heat regulator, it was stuck between the intake and power brake unit. It has now enough space, just a little bit down. http://i138.photobucket.com/albums/q...n/P1010114.jpg The steering oil pipes where also a problem, because I bought a RHD. We modified the Compact pipes for the 6-cilinder. http://i138.photobucket.com/albums/q...n/P1010110.jpg Does anybody know the Ti hubsize from the halfshaft to the wheel ? Is this te same size as an M3 ? The rearbrakes from the M3 don't fit, so I think I'll have to buy Z3 M trailing arms and probably halfshafts to. |
If you get the MZ3 trailing arms, you can use the M3 rotors on them. The calipers may be different. Do you mean the spline size on the shafts, or the size of the rear hub itself? I would suggest getting MZ3 shafts and arms due to the amount of power your engine is going to be putting out. We're able to get away with e30 parts on this side of the pond, but I wouldn't do that with your car. Some M3 drive shafts have a 4 bolt rear flange, some have a 6 bolt flange. I wouldn't mate two different shafts together unless you plan on having it rebalanced. And the power issue comes up again trying to use a ti shaft. Also, can you post a picture of the connector you are talking about? |
Pretty sure the MZ3 comes with a similar drive shaft since it has a four bolt pinion. We run M3 engines all the time with the TI driveshaft, but we're only 240hp on this side of the pond, so you'll have to decide for yourself. |
I can't find the MZ3 shafts, the M3 shafts are te same but a little longer. Hope they will fit or else make them a little shorter. I don't know if I can take the M3 drive shaft apart and put the second part of the Ti driveshaft on. The difference is very big also, the Ti driveshaft is very tiny and the construction of the M3 driveshaft is very big and strong. Maybe I can make a kind of spacer/adapter from the 6-bolts drive-shaft to the 4-bolds input flanche on the diff. |
I got the Z3 3.0 exhaust, it fits perfectly on the Ti. Just have to welt it to the M3 midpipes and it's done http://i138.photobucket.com/albums/q.../3uitlaten.jpg http://i138.photobucket.com/albums/q...Uitlaatjes.jpg http://i138.photobucket.com/albums/q...emperen316.jpg What about the difference between the temperature sensor from the Ti and M3 ? The Ti uses a flat and big sensor in the left brake-duct, the M3 has a pin inside the right brake-duct; http://i138.photobucket.com/albums/q...n/P1010099.jpg Ti sensor; http://i138.photobucket.com/albums/q...n/P1010092.jpg |
Does the US version have a carbonated air filter ? The M3 has the filter in the trunk, can I just delete it ? http://i138.photobucket.com/albums/q...n/P1010096.jpg http://i138.photobucket.com/albums/q...ffilterS50.jpg Those are the connectors we where talking about, for the people who wants to know. The Ti has only 1 engine connector, the big one with 25 pins. The M3 has also a second connector, smaller with 12 pins (just 3 pins are used on my donor M3) http://i138.photobucket.com/albums/q...n/P1010093.jpg http://i138.photobucket.com/albums/q...n/P1010095.jpg |
more pics of that intake manifold please! :D edit : to answer your questions, the brake ducts, I don't recall exactly but that is part of the body harness, is it not? if so, just use your Ti brake duct as before. If it is an engine harness thing, use the M3 ducting. I have no idea what that filter is... not sure if ive seen it or know its actual function. Not even going to try to guess what you should or shouldn't do with it. |
wanna give me your 4 cyl exhaust? ill pay for shipping :P haha |
as far as I know, you can use an M3 4-bolt shaft, and extend it? I followed an M52 swap thread and thats what he did, but I could be wrong. |
Specially for you Philly :wink: I think the carbonated filter is for the fuel-fumes, it takes the fumes from the fuel tank and leads it to the intake manifold. With my 4-cilinder it was just next to the intake manifold, don't you guys have this on the US Ti ? The extra temperature sensor seems to be from the boardcomputer. http://i138.photobucket.com/albums/q...dan/Inlaat.jpg http://i138.photobucket.com/albums/q...n/P1010050.jpg The exhaust is for an 316i, the 100hp 1.6 engine, not interesting for the US I guess |
that mani is amazing... wow I want it! Do you know anything about where it came from? |
:omfg: that mani looks amazing. i love that. so jealous you europeans have better stuff to use than us :cry: |
i want that engine too ;( |
In europe the M3 has the S50 B30 & S50 B32 both with ITB's. The us got the S52 which uses the standard M52 manifold. S50 B32 > http://www.bmwmregistry.com/faq/S50_B32_Engine.jpg S52 > http://www.bmwmregistry.com/faq/S52_Engine.jpg Loads of M3 engine info here > http://www.bmwmregistry.com/model_faq.php?id=15 |
You are correct on the carbon filter, it can be deleted. |
Rich is right and from what I understood, it's allmost impossible to put the ITB manifold on the S52. I really don't understand why they made that difference so big. Maybe because the M3 became to expensive ? Thanx Compaiar, will try it without, I can allways put it back on. |
Some pictures again, stripped the Saloon completely, also the climate control unit, that thing is huge!! http://i138.photobucket.com/albums/q.../Sedankaal.jpg http://i138.photobucket.com/albums/q...Sedankaal1.jpg Offcourse there where some satbacks again, but the engine is almost completely hooked up. The oilcooler didn't cooperate, I broke the radiator plug, the coolant reservoir didn't fit, the battery wires where to short/stiff, but thats all done now. Filled the diff with special SAF-XJ and came just a little bit to short, so I had to order it again... In 2012 it will be ready, I think... http://i138.photobucket.com/albums/q...edankaal17.jpg http://i138.photobucket.com/albums/q...edankaal16.jpg http://i138.photobucket.com/albums/q...Sedankaal5.jpg |
|
The intake manifold sits a little bit against the ABS unit, I hope that isn't a problem, we will find out.. We placed the Z3 M trailingarms and rearbrakes, M3 brakes in front and coilovers. http://i138.photobucket.com/albums/q...edankaal11.jpg http://i138.photobucket.com/albums/q...edankaal12.jpg http://i138.photobucket.com/albums/q...edankaal13.jpg http://i138.photobucket.com/albums/q...edankaal14.jpg http://i138.photobucket.com/albums/q...edankaal15.jpg |
looks like you're really starting to make some good progress |
A little video, we started the engine !! |
The M3 Compact is finally ready, it goes like a rocket :biggrin: Here are some pictures outside http://i138.photobucket.com/albums/q...t/IMG_2346.jpg http://i138.photobucket.com/albums/q...t/IMG_2351.jpg http://i138.photobucket.com/albums/q...t/IMG_2355.jpg http://i138.photobucket.com/albums/q...t/IMG_2391.jpg http://i138.photobucket.com/albums/q...t/IMG_2397.jpg |
