Re: Driveline upgrade M635csi

Hi Gaz. Weclome back, you've been missing a while. Baders, I have the rear K Macs - they do a good job of correcting the rear camber squat with Bilstein sports / H&R's, but do stiffen things up a bit. Replaced the below tyres late last year - 255/40/17 on 9" RC ET22 rims with 15mm spacers. 35,000 k'...

Re: Electrifying my '85 635CSi Euro

That is eye-opening, particularly the f/r baseline. I always thought that the E24s were closer to 50/50 balanced front to rear. I weighed mine over Police weigh station (rolling) scales in Jan. All up weight including me (89Kg) + full tank fuel - 30km travel + circa 10kg crap in boot (besides spare...

Re: Exhaust re; ‘90 635-HL

If you're not bothered about noise then the world's your oyster When I got my car the exhaust was rooted, so for a while - year or so, I ran with a single 2 into 1 edelbrock central muffler, back to twin pipes out the end. It was raucus and a hoot on short trips, would set off car alarms in narrow s...

Re: Removal of 30mm driveshaft flange nut

I've tried the JB weld 2 part mix before and is quite liquid - takes a while to cure and won't hang up in that location. I would think a putty would be more suitable; just did a quick search so something like this https://www.motoquipe.co.nz/buy/jb-j-b-weld-automotive-steelstik-steel-reinforced/JB8267

Re: Oil filter heads

I too have a M30B34 with oil cooler. Can't answer your question on the filter head but know they differ as I did replace mine. The coolers are always open. If you drive in a cold climate, especially short runs I would recommend fitting an oil thermostat - I know Korman sell them. I drive my car all ...

Re: Another Heater Core question

Mine wasn't leaking, but there was no way i was going to spend $000's rebuilding the engine and replacing everything else and connect up a 32 year old heater. Same with the oil cooler- replaced that with new as well.

Re: Another Heater Core question

Hang in there. Took me 3 weekends to replace mine. I've added a few more pics so you can see where you're headed and why it is worth persevering. The core itself will have 35 years of crap in it and the sealing between the core and the plastic casing will be absolutely buggered. As you will see woul...

Re: all gauges went out

I would remove the lower panel and trace those wires you tucked away. Note there are a couple wires that connect to the panel, one for heater cabin temp sensor (+ vacuum hose) and the other for the window lock out switch. Sounds like may be in need of a wiring tidy up to make sure everything's prope...

Up to you really. I changed my 3.07 to 3.45 and wouldn't go with a lower diff ratio than that for my tastes

Re: Wont start after engine replacement

Presuming the replacement engine is a known runner is more likely an engine electronic issue - sensor/input. Check it has spark. Check the crank position and speed reference sensors haven't been crossed over at the plugs on the manifold stay - easy to do. The cold start valve wouldn't in itself stop...

Re: Fuel system issues;won’t start. ‘85 635csi

I'm no expert but have dealt with my fair share of issues. I doubt your immediate issue is related to wrong size new hoses, however these are spec'd and sized for a reason so should replace with the correct size. If nothing else has changed since the issue first surfaced is likely other issues withi...

This is quite interesting and I admire your courage and technical knowledge. However, couple of questions: - Do I understand correctly, you are converting from 160 KW - 310 off Nm, to 85 and 220. What's the overall power to weight ratio conversion by comparison - What considerations around battery h...
