    Are there any write ups on how you actually build your harness? I understand the figuring out which pins match up, but how do I physically go about doing this?

                  1. Engine
                  M50tuB25, installed it completely stock. Only changed the valve cover gasket as I need to have it in an running asap after I broke the timing belt on my old motor

                  2. Engine Wiring
                  Cut off the e36 x20 and soldered in the one from my m40, matched them up using charts I found online, ETMs and a bit of guesswork.

                  3. Drivetrain
                  Stock G250 off the e36 with factory driveshaft.

                  4. Shift Lever and Linkage
                  Z3 lever from Blunt, Delrin front and rear carrier bushings from Garagistic. There is still play in my shifter from the old selector rod joint and rusty selector rod not being super tight fitting to the shift lever bushing. I'll be getting a DSSR when I swap this noisiy 250 for a ZF310

                  5. Motor Mounts
                  Originally I had Condor engine and trans mounts, but due to the grinding noises the trans made and the harshness when at idle I swapped back to stock trans mounts but kept the engine ones. One day I'll man up and get some soft poly transmission mounts as I'm sure that being the only flex point is doing nothing good for stock, used transmission mounts.

                  6. Brake Booster, Master Cylinder, and External Reservoir
                  I did mine a little different than most. I had an iX booster at first but it developed a leak after a few months. I then went to the e32 735 booster. Mechanically they are identical except for the vacuum port location. On the Ix it is on the opposite side of the master cylinder and on the e32 it is closer to the engine. I didn't want to run a remote resevoir for cosmetic reasons, so I ran both boosters without the spacer off the fire wall. Ths meant I had to shorten and tap the rod and slot my firewall mounting holes to fit the studs on the booster meant for the spacer. I also had to attach it to the firewall with only 2 studs. It hasn't fallen off yet so I'm gonna say it's not too dangerous a thing to do.

                  7. Steering System
                  I used the E30 resevoir at first but then swapped to the e36 res that hides down under the intake for a cleaner look. I used some combination of E30 and E36 hoses and hardlines.

                  8. Cooling System
                  I used a stock m20 rad with a 16" fan from IE wired to run off the ignition with an m42 upper rad hose and a cut e36 lower. I've recently wired up the fan to work by itself properly using a rad thermo switch from an e36 318i and swapped out the thermostat, plastic housing, factory original water pump and a Mishimoto m20 rad. Went with an aluminum T-stat housing as I've already had one plastic one crack on me and a lower temp M20 thermostat. Fan comes on at half mark, turns off at 3/8ths and temps never creep above half.

                  9. Exhaust System
                  I had to hack up a set of stock M52 manifolds to get something to clear my steering shaft and rack input shaft housing since my car is RHD. Because I wasn't running either aftermarket long tube headers or stock manifolds I had to hack together some sort of downpipe and tried tho attach that to stock m20 exhaust. I ran that mess with nothing after the cat for a couple months, which sucked. I then had a full custom system made up from a single 2.5" pipe, magnaflow cat and a dynomax muffler. Works great except for the exhaust hanger that the guy made breaking off and causing it to scrape on the ground and me ignoring it until there were holse worn through it...I am not skilled enough with a welder to fix it up properly myself so I will likely have one of the techs at the dealership I work at have a look at it.

                    2. Engine Wiring
                    E36 Auto harness with all auto trans related wiring removed. 413 red label DME

                    3. Drivetrain
                    Stock g240 and tob. Stock M50 clutch and fw. Seems to be holding up well. e36 driveshaft w/ e30 csb.
                    S3.46 diff, resealed.

                    4. Shift Lever and Linkage
                    e36 shifter carrier, and shifter. e36 linkage shortened, dont remember how much.

                    5. Motor Mounts
                    stock m42 mounts. line up good and are holding up suprisingly well.

                    6. Brake Booster
                    stock e30 moved over 1/2 inch. Have e32 booster to put in eventually.

                    318is, m50tu g240 s3.46


                      Car is a 1991 318is and aiming to re-use as much as possible.

                      Engine: M50B25TU out of a '93 525i auto.

                      Engine Wiring: Auto harness with 413 DME.

                      Drivetrain: Getrag 240 with stock mounts. M42 flywheel/pp/clutch/tob. Starter and pilot bearing are also the same part number for M42/M50. E36 driveshaft with E30 CSB linked to 4.10 LSD.

                      Shifter: Z4 2.5 lever with Euro E30 320i shift arms and new bushings.

                      Motor Mounts: E28 535i green mounts on E36 arms.

                      Booster, Master Cylinder: 944 ATE booster with stock master and reservoir. M42 slave retained as well.

                      Steering System: Stock rack with PS lines/reservoir moved to fit pump.

                      Cooling system: Stock M42 rad with modified M50 upper/lower hoses. No clutch fan and just running the aux fan for now. Will upgrade fan later.

                      Exhaust System: Ebay SS headers to custom exhaust with original E34 cat.


                        1. Engine
                        M50B25TU from a 1994 BMW 525i that was already pulled so I had no way of telling if it was good, but I took a shot cause the price was good. The owner told me about 130,000 miles and after I took it home I got the VIN off the head and took it to work and head them run the carfax, it had 133,000 miles so that was good. When I got it started up for the first time it ran perfect ever since after replacing a few vacuum lines. Came all together with alternator and all that good stuff, harness, ecu, etc..

                        2. Engine Wiring
                        E34 wiring harness with X20->C101 plug, no adapters or none of that crap it was all rewired, by ME! I read the ETM enough to be able to figure out why it wouldn't crank which was because I had to plug in the wire under the steering column that bypassed the automatic transmission wiring. Left the ECU unplugged to build up oil pressure and once I put the key in the ignition and it cranked right away, then built up oil pressure, and plugged in the ECU and it started right up. Probably my most accomplished moment of all time, screw graduating high school, this car is what made me most proud. Only other issue is the o2 sensor is I guess mounted on the other side with the E34 harness so it's a bit stretched to reach the longtube headers o2 sensor location. No issues yet.

                        3. Drivetrain
                        G260 I got off a guy locally with 77,000miles. Came with driveshaft which I need because I also 5 speed swapped the car at the same time. M20 Single mass flywheel. New CSB, guibo (flex disc), slave cylinder, clutch master, SS UUC clutch line. Picked up the trans brace with Condor mounts from GunMetalGrey and they've worked perfectly together so far. Stock 2.79 or 2.93 LSD(I forget) right now, but i'm pleased with the 2nd gear chirp that this combination produces.

                        4. Shift Lever and Linkage
                        Took the shifter carrier to Lowes and picked up a bunch of nuts and bolts that could possible work in place of the "bitch clip." Once I got home I used the one's that work, I don't remember what the thread and pitch were but they were metric to go along with the rest of the German cars. I highly suggest doing this as it simplifies the removal of the shift carrier if you need to do work. Got the Garagistic Delrin shifter carrier bushings with the optional rear delrin carrier shifter bushing that they offer and the feel is nice and tight. I'm using stock lever w/ those bushings and a UUC DSSR that I ordered with the 10° twist, but I didn't receive it that way so I heated it up and twisted it myself. Down the road I might try the Z3 shifter and see what everyone is raving about.

                        5. Motor Mounts
                        New E28 535i green guys (part# 11811132793) have worked perfectly so far. Engine shimmed with washers a negligible amount. I had to get E36 engine arms and since the E34 used different mounting locations I had to rethread the holes to the E36 location because they were nearly non-existent.

                        6. Brake Booster, Master Cylinder, and External Reservoir
                        Ate Porsche 944 brake booster from this guy on eBay, shortened and rethreaded to match E30 clevis. Used this great tutorial. Stock MC and reservoir. Not as much assistance, but it works well. ABS is still good.

                        7. Steering System
                        Powersteering-less at the moment but I just received my Continental power steering hose to try to make something work with the E34 pump. Not sure if it's different, but the E34's of the time had the servo-tronic or whatever so it might be a little different.

                        8. Cooling System
                        E36 upper hose(11531726344), and E34 lower hose(11531741418) (both trimmed), going into a E36 M50/M52 Mishimoto radiator with the 80° thermostat(1153146617480) with 82° aux fan switch(6131136427282). No Spal fan or mechanical fan yet but I have yet to need one. I will get one soon for safety measures and wire it up to work with the 82° fan switch. Original E30 M20 expansion tank.

                        9. Exhaust System
                        These longtube headers worked perfectly with no issues to the stock swaybar, we'll see when and if I choose to run larger sways up front. o2 sensor when plugged in is right next to the other header and the sensor wire is stretched a little when used with the E34 harness. No issues with that yet. Exhaust goes to a Y pipe from the headers and is 2.5" back with the Vibrant 1793 resonator and then to the Vibrant StreetPower 1148 muffler thats got 2.5" and dual 3" tips out. The same hole that the stock E30 dual tip muffler exhaust comes out of is absolutely perfect fitment for the Vibrant muffler. I love the sound that it produces, not ricey at all. Will provide clip if you guys want. Both Vibrants are straight through, but the Y pipe provides decent backpressure for the engine.

                        After doing this swap, I wouldn't hesitate doing it all over again. If you do it yourself and you're considering it then just find a motor and pull the trigger already. I doubt you'll be disappointed, and it provides the greatest feeling of satisfaction in the world. PM me if you need any help
