    Progress on my M30 swap-Engine is in!

    I got the engine in the e30 finially, and I have done things much different than Jared Squires method, and different from the e30.de ways also. Car is an 87 325iS BTW.

    1) DRIVESHAFT- When I found out that some used the 325e shaft, I figured the length was different from the i shaft. Nope, just a different size flange. So, I made a steel adaptor plate from steel stock pretty easily. Pics are below. Since the shaft joins the trans output shaft relatively tightly, it keeps everything centered. The only thing I am worried about balence wise, would be unsprung weight, but I managed to balence it in a way by seeing which way it wanted to fall to, and adding a little metal via welding on the other side.

    2) ENGINE POSITION- I dropped in the engine and tranny as one piece. I then just bolted up the trans crossmember and driveshaft. Thus, you get the engine positioned where it needs to be to use the stock shaft. I was also able to use the stock gear linkage w/out modding. Its centered, and I can hit all gears like stock. Now, with everything attached and hooked up, I lined up the engine in front, pretty much checking steering rack clearance, and making sure its not crooked. Not that it even has much play, as with everything hooked up in the back, it lines up everything for you :) Easy, HUH?

    3) BRACKETS- Once it was lined up, I just took the brackets which were flat on the engine, and tack welded a rod from there to the plate on the motor mount itself. Removed those, and HEAVILY reinforced and put together those. No measuring required, just as you go remember to keep things out of the way of the front exhaust manifold. Not too hard to do so far, Huh? :) I just used a cheapo Sears MIG welder and used angle iron and 1/4" thick flat steel, and 1/2" thick steel rods. Came out great, and they weld very well. pics are below. I don't even know the angles, but its easier to just tack weld them, and then pull them and weld away, no measuring and trying to use blueprints to make them.

    4) RADIATOR- I maybe be pushing it, but it also appears that the stock 325i radiator will fit. Its close to the distributor, but other than that, looks good. We'll see in a few days, but I think it will. I will put up pics tomorrow, but I have no idea what engine position it is! Yeah, I really don't, its the position in which everything came together good :)


    I have to still deal with the wiring, and fuel lines and such, but I hope this will help out anyone looking to do the swap. It went along much easier than I thought it would, and I found my own way, and it went pretty well.

        Please tell me you are not going to bolt on your engine with those.

        And that adapter plate...



        I'd never drive a car with those parts.
        Current:

        BMW 320i 2d 2.0 m20 -88
        BMW 325i Cabriolet 2.5 m50 -88
        BMW 316i touring 1.6 m40 -90
        BMW 320i 4d 2,2 m54 -01

          You are going to have some serious balance problems with that adapter. Might shake the car a bit. I would use it as a template and have a machine shop make you a nice clean version.

            Keep in mind that this is the cheap,kinda trial version. If the adaptor plate causes too many vibes, than I will pick up another driveshaft. I also hae used angle iron to make bracketry and such for my landscaping trailer for work, and it supports the trailer w/out any problems.

            I also know of a person with a Toyota pickup with a 528e motor in it, and if he can make that work with a little welding, anything is possible. That plate is also a lot thicker than it looks. Also, the plate is not at all centering anthing, is dosen't need to. The shafts slide onto each other, and keeps everything balenced and centered. The only way there can be vibes is from unbalenced weight, which I am anticipating some vibes anyhow. If they are severe, it'll go, otherwise, its staying.
            If nothing else, this is also an experiment for me to see how you can actually put an m30 in, not following another version.

            I almost forgot, I made the adaptor by bolting up the driveshaft to the trans, and finding placement of holes that way, thats why the center hole is huge, so I could move it around as needed to get the placement of the bolt holes perfect.

              Yeah, those engine supports need to weld the shit out of them bigtime... They need to be uber strong to take the torque you're going to give it. If I were you, I would just find a 325e driveshaft that's balanced. It will be vibration free and hook up Perfectly, like BMW intended...

                Those mounts are actually pretty beefy in real life, and its welded damn strong. I also braced it so that the force will be dispersed fairly evenly amongst 3-4 different braces. It looks thin, but believe me, they are damn solid. I got the idea for them like that from the bridge stuff I learned back in CAD and the Army, being that instead of a few points, you distribute the forces evenly, and thus reduce strain on each individual brace.

                Think of the weight of the m30 pushing on not one or two beams, but 4- meaning a lighter load on each member. Thats kinda the method I went with for them, anyhow. We'll see how it works. I am testing them before the car ever sees the street anyhow, so I can keep an eye on them and see if there are any signs of fatigue.

                  have u done a test fit with the adapter in place and rotated the shaft to see if it is going to rub on the tranny tunnel? that lots awfully big, bigger then the balancer on the reg m20...if u plan on using a shorter shifter *i.e z3* you will def have rubbing issues...and the motor mounts are those from your m30 or from your m20? if from a m30, which generation? *e23,e28 or e32, e34* got any pics with the motor in place?

                    I tested the plate, and everything clears fine. Its only about 1/8" diameter larger than the stock m30 guibo. I have no rubbing at all.
                    I beefed up the motor mounts more tonight, and installed much more metal to brace it even better. They are in and VERY solid.

                    Below are pics of the motor in, showing the postition that it ended up. Came out good, and can't wait to get the wiring and hoses all hooked up!

                      GL. Those mounts and that plate look like hell. GL.

                      the plate will give you vibrations and the mounts will probably fail.

                        im curious as to why youre not using the e30.de mounts on this? why custom?

                            You only paid $300 w/shipping? The exchange rate to the the euro sucks, thats one of the reasons why I made my own. I ended up beefing up the mounts to have better torsional resistance, and I also dissapiated the stress better. Am I cheap? No, smart, yes. If I can build mounts that work with a little work and save myself mucho money, I will, and did. The car is not going to be autocrossed anyhow, and they seem to be damn solid. They actually look beefier than the e30.de mounts at this point. Hell, one of them weighs close to 20 lbs! I will see how everything works out. If they fail, I will build better ones.

                            I also built my own b/c I didnt know where the motor placement would end up since I used an entirely different ds than e30.de, and did things a little different.

                              I paid $270 shipped. Small price to pay for it being tried, true, and tested.
