BMW 1600 Race Car Engine #?


KLawre2685

Recommended Posts

PO had the car sitting for many years and said its a 2 liter, has a single down draft weber.  It was run in BMW club events.  Have not seen the log books yet.

 

New owner is a good buddy that knows nothing about cars but he likes to have lots of details...

Is there any benefit of using an E21 block?  The car is an early 1600 with round tail lights.

 

I'm just trying to get him some info.  I found the car and he has had to put some money into it but raced it last weekend and it ran really well and now he is hooked.

 

Asked him for head number.

 

THANKS!!!

With a single downdraft carb it could be a ITB car. Which means that it is a basically stock engine with flat top pistons, some port work and a good balance job. Any idea what class it ran or with what racing organization? No matter what, he has a track toy and he should have some fun with it.

The only way to know what you have is to take it apart and inspect EVERYTHING!! Buying a race car that is "on the button" or "Track ready" just means it starts and will move across the parking lot under it's own power. Unless you know the guy that put it together PERSONALLY, and trust him with your LIFE you will at least go through the car and make sure it is safe.

When were the rear stub axles crack tested last? How many hours are on the engine since the last rebuild? How many times has it been over revved? What is the compression ratio? Do you need 110 octane race fuel to keep it from melting down? Is the roll cage even attached to the chassis properly (I have seen more than a few get punched right through the rotten floor when they got used). Did you even look at the driveline Guibo?

Yep - he just called me back and looked at the BMW/SCCA logbooks.  It is a 2 liter ITB car.  The non-M10 block number threw me off.

 

We had a local shop do the prep and stub axles were fine and comp test came in at 165 - 180.  No idea about hours on engine but may refresh after next season (4-6 weekends a season for us).  We are running 100 fuel.  Cage is welded in and no rot in car at all - underneath is clean. Didn't look at the Guibo but shop said it was good.

 

He is a brand new driver and this was his first time on a track other than school in May.  He ran 1.39s at Summit Point on a cold and damp track.  He drives a good race line and now we will work on braking and shift points next year.

If the engine was built properly (and legally) it should be safe to about 6800 but will be all done making power by 6300 (spinning it past 6300 just makes noise, heat and shortens the life of the engine). If they used aftermarket rocker arms and/or weak valve springs (in ITB legally they should be stock single springs) anything above 6500 you stand a chance of "floating" the valves THIS WILL BREAK ROCKER ARMS! Pay attention to the oil pressure when turning right and/or braking hard, if the oil pan is not baffled correctly you will have a loss of oil pressure.

Isn't there supposed to be a '+' on each end of the number by that point?

 

And if you look closely, the numbers aren't exactly aligned, as if they were stamped individually instead of in a frame.  And...I've never seen an M10 motor number lead with a zero.  The shape of the numbers is proper, but it just doesn't look factory.  And a factory remanufactured engine has a totally different numbering system that uses letters as well as numbers.  

 

But...it doesn't really matter as the car is a race car, not a restoration, and it's doubtful if the engine is hot (as in stolen).

    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
