Kugelfischer Fuel Injection


Recommended Posts

Hello BMW family,

 

I am inquiring to find out if you replace the original camshaft on a 1974 BMW 2002tii, with a schrick Camshift?  Will the replacement  effect fuel flow and will not allow it to match the airflow for a Kugelfischer injector. Will it change the flow.  If a Schrick Camshaft can replace the original how do you make adjustments on the fuel injection? Thanks

The 2002ti and 1600ti discussion is focused on the "ti" cars: they had twin sidedraft Solex carburetors. Your post will probably get more eyes in the General discussion.

 

But, yes, although tii's have occasionally been "upgraded" with non-OEM camshafts, a near-consensus is that the hotter camshaft will not be ideally matched to the Kugelfischer pump, and -- although you might have greater performance in some portions of the power range -- you're probably sacrificing the amazingly-broad and smooth power of the stock tii setup.

 

When the Kugelfischer was still "modern technology", tuners such as Alpina had expertise and parts that facilitated modifications to the pump's output. Those days are largely gone. Shops with lots of '02 experience, e.g., Korman, do not recommend hotter camshafts for tii's.

 

I’m just wrapping up the rebuild of my ‘73tii’s engine. Although we increased the compression ratio from 9.0 to 9.5, matched intake ports, extrude-honed intake runners and exhaust manifold, performed some lightening, balanced to a high standard, and had the Kugelfischer rebuilt, we replaced the slightly-worn original camshaft with a new factory camshaft. Not fired up yet, but I have my fingers crossed.

 

Regards,

 

Steve

Steve,

Can't wait to learn how well the tii rebuild runs. I am sure it will not disappoint.

    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
