BMW 316 ENGINE


Lawrence

Recommended Posts

I am enquiring if a bmw 316 can be with an 1800cc engine on it. The engine number is 18 4v d 731 603.

Is the engine 1800 cc or the BMW 316 they were launched only with a 1600cc?

Anyone knows about it?

Regards,

Lawrence.

a factory rebuilt unit. If it were an original Neue Klasse 1800 engine, it would have a six or seven digit engine number that would have matched the VIN on the car it originally came in.

no Neue Klasse or '02 series engines' serial numbers had letters; just numbers, either six or seven digit.

Not sure if there's a block casting number that would reveal the displacement, but you might check the cylinder head--if its a 118ti it may be a 1600 or 1800 engine; 121ti would be a 2 liter.

On top of my head:

E21 316 before the facelift: 1600cc

E21 316 after the facelift: 1800cc

E30 316/316i with a M10: 1800cc

Not sure when the E21 engines became 1800cc, I think it was with the facelift in 78/79 or so, but I'm not sure.

Another way: look at the freeze plugs in the block, if they're on the intake side as well it's an engine with a large (89mm) bore.

If not, it's a small bore block and as such, a 1600cc.

Or you could have a small bore block with a long stroke crankshaft, but I believe that combination was only used in the TISA.

THE car model IT MIGHT BE LATE 70'S OR EARLY 80'S....It is a BMW 316 but the number that I've wrote down I think is the engine number which I found printed near the safe starter.

I wish if someone can tell me if it is a 1600cc engine or an 1800cc.

If you are looking for the 1800cc motor as used in the 1800ti, you can either use the BMW 1800, 1800ti motor with the 116 or 118 heads. The 116 head was used up to about 67, then they started using the 118 head. There is only a diffrence in the combustion chambers and the chain tension gear. All early 1800 motors as used in the 1800ti to about 1967 had a 84mm bore and a 81mm stroke. In 1968 they went with a 1800cc motor with a 89mm bore and a 71mm stroke. The late 1800s , all 1802s and 1.8l 316's 318's and US 320is had the latter motor specs. I don't think that the 1800ti ever came with the later short stroke 1800cc motor.

    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
