Re: Engine Ground - 1974 530i

If your only ground to the frame/sheet metal is to the hood, that's not good. Get a ground strap and attach it between the block and the frame. Too many grounds isn't a thing.

Re: e12 temperature question

The fact that the engine temperature goes up when you're working it harder is not unusual. On my E3 the temperature will vary by 25°F depending on the outside temperature and the power level of the engine. It has been like this through 3 engines in 14 years.

Re: ballast resistor with conventional ignition

The polarity will have nothing to do with the primary current, the AC and DC resistance is the same regardless of which terminal is positive and which is negative. Improper polarity will affect the secondary and the ability to generate a hot spark. http://www.mossmotoring.com/coil-polarity/ The wire...

Re: CFM of radiator fan?

very interesting the electric fan modification... if you can post some pictures of your auxiliary fan, did you guys use a reversible fan and mounted it in the back of radiator? The BMW 64541392913 2-speed auxiliary fan is built as a pusher and is mounted in front of the radiator in its stock config...

Re: CFM of radiator fan?

I deleted my mechanical fan many years ago on my E3. I use the 64541392913 2-speed auxiliary fan from E32's or E34's as a pusher fan. I use a Volvo 2-speed fan control relay triggered by a BMW 90°/99°dual thermoswitch. As long as the car is moving 35 mph or so the fan never comes on. If I'm stuck at...

Re: We did it: E28 subframe swap...

We are in search of an early E28 cover that will bolt up directly. Bill PM me with your address and I'll hook you up with one. I have a few in my collection. I used straight pieces of the steel tubing from the transmission cooling lines from an automatic BMW ( maybe an E34 )for my sheath extenders ...

Re: E12 Project help needed - e28 rear end swap

I stayed with the E3 rear sway bar for two reasons.
1. It is an aftermarket ST version.
2. I didn't feature removing all the stuff and insulation from the inside of the trunk to weld some brackets on and not burn the car down. It was much easier to do it out on the floor on the trailing arms.

Re: E12 Project help needed - e28 rear end swap

I put an E28 rear axle in my E3, and the problems you might incur should be common. 1. As mentioned earlier, you will need the differential cover from an early E28 with the centered mount. It will bolt right on to the stock mounting point. Otherwise you will be fabricating an adapter. 2. You will ne...

Make sure you have an early E28 differential cover as it will mount in the stock bushing.

to all who responded. Sog... I'm not clear on why there are 3 different sizes of bushings ...were there 3 different sway bars made 1 mm apart? What am I missing? The 23mm bar is 20% stiffer than the 22mm bar and 43% stiffer than the 21mm bar. Perhaps the engineers were trying to fine tune the suspe...

It's an M30B35, so it's not much different. I run 36° total mechanical timing with another 14° of vacuum advance added in. It's not the stock distributor, it's one for a 2800CS, but it was brand new and $75 on eBay. I've never checked the stock timing mark once I got my new one going, I just run the...

I've not done it but I understand fitting an e28 subframe and differential is pretty straightforward with more ratio choices and better availability of limited slip units. I've got an E28 subframe under my Bav and it works very well. If you get the right diff cover it bolts right in on the stock mo...
