    Interesting Decision to Make

    I just completed the installation of a complete Ireland race package on a 1990 325is. Now I am ready to move on to the engine.

    I recently bought a wrecked 328i to get an engine and trans for the E30 which I reported here http://www.r3vlimited.com/board/showthread.php?t=70211

    I've worked a little on the 328 and it looks like it can be fixed relatively easily. That is relative to the amount of damage. The rear panel is available from BMW for about 130 bucks. The rear quarters are pulling straight with some effort. So, the 328 is not necessarily a lost cause.

    Recently, I bought another wreck... a fairly well mangled 95 740i.. T-boned on the passenger side. 'High mileage, but the front end parts can be used to repair a lightly hit 97 740i that I previously picked up. I figured the engine was probably a lost cause because of the high mileage and the NikaSil problem that those years had, but the surprise was that the engine had been totally replaced about 50k miles earlier. I found this out by tracking down the original owner from a campground parking pass left in the front window. Unusual that the insurance company didn't clean that out... they usually do.

    So here I am with two choices of engines for the E30... a 6 cylinder M52.. or an 8 cylinder M60 series motor... pre OBDII... including all electronics and wiring.

    So what should I do? 6 or 8 in the E30? And, if I do the 6, what do I do with the E36 body after I've taken it's engine? Has anyone heard of someone putting an 8 in an E36, and is there a website that documents the effort involved?

    I think that if I go with the 6, it could be heavier in the nose than the existing 6 which might upset the handling. OTOH, I think I read somewhere that an aluminum 8 from the 740 might actually be a lighter engine in the E30 and positively affect the weight balance ratio?

    2002maniac was over working in my shop tonight. He thinks I should go with the double switch.

    i don't have any hard facts/figures, but even if the m60 was heavier than our m20s, it also *should be* shorter front-to-rear (think only 4 cylinders long vs 6); depending on how its mounted, the extra mass may be negligible for the purposes of weight distribution or change in polar inertia. Furthermore, if the engine is in fact lighter, it may be a most excellent choice for all the reasons above as well as power-to-weight ratio.

    A lot of people have done m52/m50/related swaps, and they are well-documented and a lot of people can help answer questions. This is great as you won't be passing into uncharted territory - but i personally think the 8 would be a more interesting, more potentially powerful, and definitely more unique way to go.

        IMO there are a ton of M50 etc swaps out there. The M60 would be a very interesting swap and it is always cool to be different. Probably more work involved in the swap since there will not be as much info on it, but I say go for it.

            13 lbs more weight than m52? Hell yes.

            do you have physical dimensions too? i'd like to know how much shorter f-r the m60 is.

            saleen, if you could find the 6-speed from the 540i sports, and lose the clutch delay/diverter valve, that would be a killer combo.

              V8 runing two seperate MS systems FTW - not kidding.

              BTW - I put a m30 into my car - and the affects are not really noticable - everyone that has never done it talks about the added weight - but in reality - it's nothing. Of corse I delete my AC - so that might help a bit - but really - e30's are not as light as say a 2002. It a non issue - dispite what you might read.

                here is a little little on AKG Motorsports '98 V8 4.4L with 6-speed swap into a 90 e30 325 chassis

                  do the 8. the m50/2 swaps are cool and a great setup for these cars as well as being a well documented alternative to the stock power plant, but damn the 8 would be sweet. It doesn't weigh that much more so i don't know that the handling will be that much more adversely changed compared to the six cylinder swap.

                    Easier to do one swap than a double swap.


                    Keep it slideways!!

                        why would you need two MS systems? Why not just use the stock engine harness? It is OBD1 which should make it easier.

                        If I was going to do a V8 swap it would have to be an LS1. Edelbrock has a Carb kit that would make wiring super simple.

                        The LS1 is also lighter and could easily get 400 at the wheels with basic mods.

                        Of course the M60 installs I have seen look very clean and seem to fit like a factory endeavor.

                        Hard decision.

                          I've only located two websites that describe the v8 installation so far. One is the one mentioned in Illinois, and the other is on a german web site. Fortunately, I am fluent in German so I was able to get a lot of good information there. One thing puzzles me... how do they get the brake cylinder to work located in the front of the car? I guess it is just a big long rod from the brake pedal or?

                            AKG's site has some pics not much info though, if you look the brake cylinder is basically behind the headlight.



                            Small pics but can give you an idea.
