so what's my engine?

[ptegler]

inherited..but NOT in a 2002.
South American DB says it's a 1968 (based on the engine serial number +1662609+ )
The cast in markings of the head though suggest a newer head, dated  1969 (July..7 dots?)       121   T1

and the side of the head


So my question here revolve a round some naming conventions and what it took to find the right pulley (at least as received)
 

WHAT is  the terms   tilux nk  mean amongst models/versions /yes?
My pulley looked look one large, with two small right up against the largest. which is the furthest out (<4.5"?)

I could find many 1 and 2 pulley version for the early m10 2L, but not many like thi.The distinguishing feature
is the 'bolded' text query above.

ptegler

anyway.... i just trying to determine if this is an oem, from a '68 2002 of if this engine is a Hodge Podge.

For those reading this thread the question relates to mid-late 1960s BMW engines.   I'm better with E9 engines (M20 and M30) as thats what I own but I have some working knowledge of the 2002 as their engines crossed into the E9 early on. 

 

NK refers to Neue Klasse.  This notation means you are likely referring to the 1500, 1600cc, 1800cc and 2000cc engines that were used in the Neue Klasse.

 

TI/SA used to refer to the high performance variants of the NK series of engines. 

 

Refer this historical article to put some context on the BMW model evolution:

Reading the article, it appears the Tilux was a TI high performance spec with upgraded luxury in the NK series of models.  

 

My vague understanding is these engines were retroactively called M10 engines in the 1970s - wikipedia seems to confirm that.

As it currently sits. (Well.... after big time cleanup and much re-hab)
As acquired, looks to be the last original Rotus chassis, and only one ever built with a M10 L2  4 speed drive line.
