Hey everyone, 

I've been reading some threads regarding the bumpers on our cars, but I remain unclear of a few things. Does my car (69 1600) already have the more desirable shorty bumper? Do people tuck in my style bumper, some cars look like their bumpers are shorter. I'll appreciate any advice or suggestions.

 

Thanks

 

Alex

Hi Alex,  

 

Bumper ?: Yes

Bumper shortening ?: No

 

In regards to bumpers, you've got just about the best most anyone can ask for.  Some opt for a few small changes like the lower-profile euro-market bumper overriders and license plate lights.  As a former designer, I prefer the taller us-spec overriders, they add a needed "vertical" element to the body shape.

Calling any battery wire gauge experts!

 

So I've decided I'm going to make my own battery cables but I haven't found a clear answer on the gauge I should use. This isn't a battery relocation project and right now that is not the goal. I'm in the process of putting some things back to together to see if I can start this car by next week.

 

Anyways, I didn't want to spend $50+ on the stock ground wiring, and was wondering if there's anything I can do to upgrade the wiring. The stock ground is a flat non insulated wire and I would like to change that to something insulated, but don't know what gauge to use. The positive wiring isn't looking too good at the starter connection so I figured I can change this to.

 

Thoughts? Any don't dos? Should I keep the original setup or should I proceed with the plan?

 

Again, I'm not interested in a relocation discussion, i already seen a thread (that otherwise would have addressed my doubts) turn into a relocation debate.

 

TIA guys

If you look at the wiring diagram the battery cables are given as 16mm2 which are not massive. This is an equivalent to 6 AWG wire. Maybe get something a bit bigger but no need to go too big. 

 

The ground strap, with two legs comprise of a 16mm2 and 8mm2 straps. To replicate this, the main thing is to connect the engine block to the battery using a new cable. You can then connect the block to the body with another cable the same size. 

 

Get prepare cables with factory crimped terminals. Alternatively, if you want to make them yourself, use solder lugs. Avoid anything that screws together to grip the cable.

thanks for the advise. Do you think I can go with a 2awg on the ground wire from battery to block, and 4awg on the positive side? Do you happen to know the size of the lug diameters I need?

The ground and the positive cables only need to be the same size. 4 AWG will be fine for both. The battery terminals are the standard 'small' size (whatever that is) basically not truck sized. Once upon a time the positive and negative terminals were slightly different sizes but now I think they use a single terminal that does both and modern batteries are designed that way. 

 

I think the lugs are 8mm for the terminal on the starter motor and that will be the same for the block.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
