Re: Has anyone ever installed a cruise control mod? If so, what model?

Lock, This "kit" requires the magnetic VSS speed pulse sensor - so I'm presuming that it ignores existing speedo hardware entirely. I'll need to research where Rostra says the speed sensor is best placed. ....Also, if I went to a pick and pull for a cruise control....I'd probably end up buying the ...

Re: Has anyone ever installed a cruise control mod? If so, what model?

I think back in the day BMW dealers fitted aftermarket Escort units to late e12 528is :?: Why not raid the factory cruise from the e28 :?: 8) For me, I had an e34 parts car for a while, so plenty of time to pull parts. And the cruise control was modular, not integrated into the ECU, so it was easy ...

Re: 77 530i motor into a 77 730i ?

No problems, in that case it would be a minor downgrade, 3.3 to 3.0 liter. As I understand the connecting rods are the same length in M30 motors, it's the wrist pin location in the pistons which is moved for the different stroke, but I could be wrong. In case you were thinking of swapping the cranks...

Re: 1976 BMW 530i "Eleanor" rebuild project

Hi Mike, great posts and pictures, thank you for sharing. It's great to see this teardown in detail and I know it takes a while to make each post. I wanted to ask about your removal of the crankshaft bolt, according to spec on the M30 motors it's supposed to be torqued to 302 ft lbs. I'm wondering h...

Re: 77 530i motor into a 77 730i ?

From what I've read, they are an identical motor and transmission and all the parts including the ECU are the same. There might be small differences but not enough to matter, the 7-series is just a slightly bigger, slightly improved e12 5 series. I don't know of the 730i being sold in the US, only t...

Re: Cylinder head

I was just talking about this with Eric the other week as we're both doing injector work. You can get parts here: https://9fc49591-6086-4288-b49e-0823e9968378.filesusr.com/ugd/83fc94_acdab26f65bd42de90719f89b09c7e00.pdf You'll want page 14, "Bosch Hose Type Injector" parts and you're probably after ...

Re: Ignition Tumbler

Also it looks like my lock was replaced in 1988, so all the lock bolts were already replaced with normal hex heads making my job easier. After never having a working 'start' function, I just discovered that when you release the key from 'start' back to 'on', if you turn it to 'start' again it doesn'...

Re: Proper coolant (or newer types that protect iron blocks)???

I'm not too fussy with brands but I change my fluids fairly regularly. I use Prestone concentrate and mix in distilled water after hosing out the block and radiator. If you haven't done it, definitely remove the drain hole underneath the exhaust manifold because that will fill with sludge. Anyway I ...

Re: Blaupunkt Radio Recommendation

If it helps I found with these cars - 1. the negative speaker wires are grounded in our cars, and all but the most basic radios since the 80s have balanced speaker outs - they won't work right (possibly be damaged) if you hook them up, so run your own speaker wires. And 2. The "power" cable for the ...

I don't have a dog in this fight, as my 81 E12 is a 5-speed, but I like your style Lock. Kitchen sinks are made for AT repair.
Had the house to myself that entire weekend, and spread transmission bits all over the kitchen as I cleaned them. I highly recommend it if you can get away with it!

Re: Ignition Tumbler

Good timing, I was also replacing the ignition switch on mine last weekend. I found a few guides, and successfully removed the old ignition switch (cutting the wires and breaking it on the way out in the process). https://forum.bmw5.co.uk/topic/85761-changing-the-ignition-barrel/ http://www.mye28.co...

Re: Cylinder head

Just wanted to add, even tho they do mention it, cleaning and drying the headbolt holes before reassembly is really important with M30 motors, not just for correct torque specs but also to avoid the block cracking. I had to scrap an e34 535i because the block was cracked due to whoever replaced the ...

Re: Has anyone ever installed a cruise control mod? If so, what model?

Maybe a little OT, I haven't done this, but am planning to. I have all the kit out of an e34, which includes the computer, accelerator cable actuator, stalk, gauge cluster and wiring. All I need then is to either install the Porsche speedo ring and sensor I have on my axle, or put in the e28 subfram...

Re: Automatic transmission problem

What color is the fluid, was it changed recently before this? How was the transmission before that, weak shifts or okay? Is it making any noises now (or before it stopped)? Mine had a flaring 1-2nd shift, dirty old fluid had clogged up the transmission valve body and there was a torn gasket internal...
