Mador 0 Report post Posted March 2, 2012 Last weekend I pulled an M20 engine out of my E34 that was like a slow whale.. I took this friday off (today) and drove to Temuka to pick up my complete M50, Got most of the Electrics installed properly with the rubber grommets and what not, but have run out of light and will get onto getting it installed tomorrow haha, will get pics up when i get a cam No doubt will ask for a few hints on plugs and what not Oh and I have a question, I left the Manual Getrag in place, will the flywheel and clutch fit the M50 from the M20? its a single mass or whatever flywheel Thanks!

Ben 0 Report post Posted March 2, 2012 (edited) Yup common practice but you will need to take some meat off the back of the flywheel and use an e21 release bearing. EDIT - beaten to it lol Edited March 2, 2012 by Ben Quote Share this post Link to post Share on other sites
Mador 0 Report post Posted March 2, 2012 Nice thread on it, glad to know it will work, have a spare getrag 260 aswell, but dont know wether to use the Getrag 240 or 260, I have all the mounts, and exhaust system even, to have it installed and running tomorrow, but will wait for turbo conversion Quote Share this post Link to post Share on other sites

EDIT - beaten to it lol alright so definately need to cut some of the flywheel off? alright, anyone know someone in CHch who will do this? I have a Mill and a Lathe but wouldnt have a clue on balancing it?? if im right it needs to be perfectly balanced Quote Share this post Link to post Share on other sites
Mador 0 Report post Posted March 2, 2012 What are you using for tuning? I have a standard ECU i put in this afternoon when I bolted the loom to the firewall, got carried away and tried to rush install before dark, also have a megasquirt im gonna flip a coin to use or buy something tuners recognise :S no idea, i like to mess with things myself so thinking megasquirt Quote Share this post Link to post Share on other sites

Nope dont bother with a piggy back dme uses internal ignitors making it difficult to tune ignition timing Either get the dme remapped or use a standalone Ive looked into every alternative including fmu, safc2 etc. and these are the only two that are worth doing imho Just use your megasquirt its been proven to work and it will save you alot of time and effort Quote Share this post Link to post Share on other sites
thorburn 121 Report post Posted March 2, 2012 +1 for not using a piggyback. Especially not for that price If your not going to be tuning it yourself i'd suggest using what your tuner would prefer to use. A megasquirt might save you money up front will cost more in the long run. Another option (although quite expensive) is link's plug in for m50 engines. They'll cost you the same as the other plug in link ecu's Quote Share this post Link to post Share on other sites
Mador 0 Report post Posted March 3, 2012 Alright awesome ill stick with the MS, have found a wiring diagram for it too so that makes things easier, now just need to find a diagram for the M50 harness to wire it together, I see people wire the MS into the passenger floorwell, cant you just leave it in the stock ecu box? run a serial cable into the glovebox for the tune?

Mador 0 Report post Posted March 4, 2012 Ive got the engine in the garage and have put most of the loom back together, and all the manifolds back on and what not, im stuck with a few things Next to the MAF connector there is another smaller connector, whats this for? Next to the MAF Intake Pipe to Throttle Body there is a small bolted in 2 piece hose tail connectors, what are they for? Under the Throttle body there is a coolant in and out tail connectors, what is the third one for? Thanks for your help! Quote Share this post Link to post Share on other sites

Thanks for your help! charcoal canistor valve. nothing to worry about, can leave disconnected. dont understand what your trying to describe. got a picture? if its on the airbox it could be the thermostat for the throttle body heating system pretty sure its part of the charcoal canistor setup. block it off if not using the charcoal canistor.

You mean that little reddish brown thing thats over by the front wheel/ LH headlight? I dont mind using it again, for now anyway as I think I know what you mean and will get that sorted thanks and I think it may be the idle control valve connection thats on the same loom as the MAF connection Edited March 4, 2012 by Mador 525i Quote Share this post Link to post Share on other sites
polley 916 Report post Posted March 4, 2012 Im not familar with the E34 so im not aware of its location but its for venting the gas tank, its controlled via a valve by the DME. Goes from the gas tank through the charcoal canister, then to the intake manifold / throttle body. (thats it in your first digram) Yes thats the idle control valve.

(thats it in your first digram) Yes thats the idle control valve. sweet thanks for that, the other guy said leave it - but im guessin BMW put it there for a reason so im gonna leave it alone to do its thing lol I just looked at the ICV after work and ive already hooked it up to a cable that came from underneath the manifold that looked about right so Im still stuck with the cable that comes off the loom bout 60mm down from the MAF sensor Id really take some pics but I havent got any batteries till Payday only takes lithiums alkies are dying at the flash lol Quote Share this post Link to post Share on other sites
polley 916 Report post Posted March 5, 2012 (edited) the plug that comes off by the MAF plug is for the charcoal canister valve.. BTW, you prob want to remove the charcoal canister and just let the fuel tank breathe freely. Edited March 5, 2012 by polley Quote Share this post Link to post Share on other sites
slowe30 0 Report post Posted March 5, 2012 wouldnt doing that vent fuel vapors into the engine bay or where ever it is you decide to vent it? honest question, thought it wouldnt be to happy letting fuel vapours get near hot things or sparky things haha. i spent the couple of minuites hooking it all up just to be safe, as hes said bmw put it there for a reason why not use it? it must do something purposefull Quote Share this post Link to post Share on other sites
Allanw 1071 Report post Posted March 5, 2012 They're really an emissions thing. Dads E30 never had one - it's NZ new, and has NO emissions gear on it. The hose coes up from the engine bay, and curls over than finishes! I would have thought it would have the charcoal cannister - they don't hurt performance, and must be cheap enough! No reason not to connect it really. Unless it becomes a nightmare Quote Share this post Link to post Share on other sites
polley 916 Report post Posted March 5, 2012 Like Allan said, its for emissions. If your getting rid of the standard DME, you will have to setup your aftermarket ECU to control the valve. You also have the potential to overpressure the fuel tank with boost if you get it wrong. Quote Share this post Link to post Share on other sites

Mador 0 Report post Posted March 31, 2012 ALRIGHT!!! After bout 4 weeks of trying my best to hire an engine crane, FAIL, Bought one today with a Bonus we got from work at end of tax year ($320 for quality control lol) got it from super cheap auto, bloody cheap chinese engineering, but it worked, M20B25 is out Left the gearbox in to position the M50 against the Getrag 240 so I can get some dimensions to make some custom mounts lol The M20 mount fits the M50 so Im gonna see if I can mix and match mounts to get is close, might be able to get something right, If anyone needs to Borrow an engine crane in CHCH give me a yell Quote Share this post Link to post Share on other sites
