Oh what fun, more developments.
After installing the slave cylinder, the clutch would still not release properly so I could get it in gear. After much bleeding (proper bentley procedure and all) still nada.
After much research it appears the clutch disc may be in backwards. If not that then something else is wrong with the clutch. Either way, I'm yanking the transmission tonight to check it out.
If I could afford it I would have a single mass flywheel in there, but I can't and don't. Boo on me for fucking up...

Also a good thing to note, I tried keeping OBD2 for cheapness sake (with the e39 harness - ugh) and the hope that good obd2 tuning software will be available eventually, but it was a big mistake.
I still have everything for the OBD2 form of the engine and will keep it but get an e36 obd2 harness if the time comes tuning is easier.
Right now I'm learning the details of tuning the 413 and trying to figure out if I want to get an eprom reader/writer to make my own chips. I have a TRM chip that came with my dme, but its not tuned for my pink injectors...Leave a comment:

Pin #8 (bk/wt on mine) is the fuel consumption signal, which won't be accurate, but its fun to watch it fly around in the cluster when you rev the engine LOL
Pin #9 (bk) is the tachometer signal. This is a critical one as is #14(bk/wt on mine) which is the DME engine speed signal.
Even the ETMs do not show some wiring for the 91 318, like I said earlier, I went to the fuse box and traced wires based on the fuse description and Bentley/ETM descriptions. I used the Bentley for the e36/92 318, it was reasonably helpful.
The biggest issue, which was minor, was the alternator differences. I have a 120amp bosch alternator that only has a single power post and then a 3 pin connector, and the power on the harness had 2 connections. I had to wire up my d+ connection to the connector to get the alternator to charge the battery while running. It was as simple as connecting the d+ wire(smaller) for the alternator to a spare 3pin connector pin#2.
Keep in mind I tossed power steering and air conditioning so I didn't worry about those connections at all, both the a/c compressor and ps pump looked larger than the e36 ones.
I found those sites as well when looking at wiring, the bentleys and etms were the most helpful.Leave a comment:

Interesting build!.... You have any issues with E39 specific parts vs their e36 counterparts? As far as diagrams go i get alot of mine from these sites:

Awesome man!! I am super excited for you!! I may recruit your expertise when I do my future S50 swap...Leave a comment:

some random notes for anyone doing/planning a swap like this:
WIRING:
Electronic Troubleshooting Manuals (ETMs) are your friend.
It is stupid hard to find all the pinouts for a 91 318, even with the ETMs and Bentleys. I ended up going to the power box and testing out some wires to be sure, I wanted to be 100% positive nothing was going to fry.
Before starting this project, I could wire up a replacement light socket. Now I understand the entire electrical system of my car and know what every wire on the engine and in the fuse box does. Its awesome.
All the electrical hookups are not hard to make, but I probably spent about 50 hours going through wiring diagrams and testing on the car to make sure it was right. Two pins on my c101 did different things than EVERY other diagram I could find.
MECHANICAL (not brake booster)
Everything mechanical was easy to do. Engine mounts, transmission, driveshaft, diff, etc... is all basic wrenching. Nothing hard about it.
I dropped my engine/tranny in together and it worked fine, scratched the heater cover a bit because I didn't jack up the back of the engine enough once it got down in there. The moment i raised the transmission about 4 inches in the back, it went in like butter.
I do recommend bolting the driver side engine mount arm to the engine after dropping it in, otherwise it is a bitch to line up the bolt on the rubber mount with the arm.
OBD1 Conversion
Buy new sensors. As a refresh for the engine, get new ones, its worth it for the maintenance. Also make sure to get the M50 manifold mount arms, it makes routing hoses easier and pretty much everything under the manifold look a lot cleaner.
Brake Booster
All the options people list are viable. My setup ended up being a booster from an e32 and a master cylinder from an e34. The e32 booster had the clevis fork cut off and a new rod welded on to accept the e30 clevis fork. I've been welding for 15 years, and if you go this route I recommend having it done by a pro (not me LOL).
random thoughts
While it would be awesome to have a beautiful car, like many r3vers, I have a wife and kids so I can't spend lots of money. I started with $2500 and right now, after buying and selling parts and the 528 donor, I still have 1800. It took a long time to get where it is, and I am okay with that. I'll most likely pay to have the exhaust done since I have cash for it.
Over time I'll spend the time/money to make it beautiful, right now I want more go than show.
Also, r3v is a wealth of info and inspiration. Awesome. you guys rock.Leave a comment:

Thanks dudes, once i get that clutch slave cylinder in there i shall tear down the street with open headers and post video of the awesomeness.Leave a comment:

Hey r3v, guess what? It runs.
It fired up first try with a good, charged battery. This is me firing it up this morning in the cold (note frost on windshield) after doing all the wiring adapter harness soldering last night.
A few things left to do:
Tidy up the wiring and put the covers back on.
Replace clutch slave cylinder. I'm a moron and didn't pull the proper one from the other car. Correct one is on order, should be here tomorrow or wednesday.
Fabricate exhaust (taking it to a shop this week for estimate).
Replace dash (perfect one in the garage).
Clean interior and install stereo.
then all the other projects to make it awesome, like cobbling together a turbo.
Total spent so far, including buying the car, selling the 5 series, selling parts, buying parts etc... is just a hair over $700.Leave a comment:

I just realized i haven't updated the thread in a long time. I'm not done yet though....
Also note, my camera broke. I got a new one but only have crappy cell phone pics...
I got the engine in and mounted properly, not to bad actually, it took about 2 hours to get it all in and connected at the transmission/driveshaft etc...
Everything else is hooked up, except the dreaded wiring, the exhaust, and brake booster.
Don't mind the hose coming off the ccv, that will be sorted out.
also i've gotten a new radiator hose that isn't chopped funny...gotta put that on...
Keeping obd2 with an ews3.3 setup is impossible. I am in the process of finding a harness & dme to redo all the wiring for obd1. also need to find a crank and cam sensor. i have all the other parts.
I had to try to keep obd2, since it would have been cheaper. I wish i could pay someone a couple hundred bucks to delete the EWS from my computer and stay obd2.
Hopefully this week i'll have the brakes sorted out, the exhaust finished and then i can redo all the wiring this weekend.
...unless someone knows how to defeat ews3.3...Attached FilesLeave a comment:

Finally. The swap has begun. Engine pull pics...
It rained all weekend, but considering I've had to put this off for so many damn weeks, I braved the rain and hail to get this goin.
Old Blue poised to donate its heart and soul.
Clive waits patiently on the street.
Just about everything disconnected.
Hooked up and ready to go!
15 minutes later:
Total elapsed time to this point, considering stopping for some torrential downpours and beer breaks, about 8 hours. Longest engine pull EVER. Ugh.
On the stand, ready to be prepped. Clive is now back in the driveway, still waiting.
\
Oil Pickup and pan installed:
As it sits right now, m52 manifold removed, motor mount arms installed, aluminum thermostat housing & new thermostat installed.
Tonight will be the completion of the m50 manifold swap, since I'm keeping OBD2 I have to make all the connections underneath.
Awesome obd2 m52 to m50 manifold swap guide.
Since I broke the water pump pulley getting the fan clutch loose, I need to get one of those. Also replacing the water pump.
I've gotta do a search to find the correct length belt for the m52 minus power steering and air conditioning and get that purchased too...
I want this thing running before the weekend!!!Leave a comment:
