: However, I did pull the motor out of a '66 2000TI, and it was equipped as follows:
: -TISA manifolds;
: -45DCOE 15/16's with low serial numbers, setup as for 1800TISA;
: -large, black cylindrical air filter, with one paper element and intake horn at each end;
: -121T head, apparently ported/polished at the factory;
: -an unusual camshaft-- no number on the forward flange (where usually there is a "1", "2", or "3", and the flange seems to be hand welded (with beautiful craftsmanship) to the shaft;
: -standard sized valves for 2-liter motor;
: -cylinder bore is the same as the 2-liter motor;
: -pistons have crowns, with recesses for the valves.
: -exhaust manifold had some sort of whitish ceramic coating on it. Unfortunately I didn't grab the manifold before the wrecker towed the car away.
: If anyone has any information as to how this setup ended up in a 2000TI, I'd like to hear about it. I noticed on the Schnitzer website, http://www.ac-schnitzer.de/englisch/sport/historie/index.htm that Josef Schnitzer won the 1966 German Championship in a 2000TI. Perhaps in '66 BMW setup some of the 2000TI's with the TISA equipment to get into the race?
My guess is that your cars engine recieved a head and carbs from a 1800tisa. As you know 2000ti's and 1800ti's (as with the later 2002ti) came with the solex 40PHH carbs, which can be problimatic at times (I know I have some on my 68' 2002 --they came off a 2000ti). Probably some previous owner found this weber setup in a wrecking yard in the early 70's and pulled the stuff and put it on his 2000ti to cure his erratic running problem.
Check the motors block serial number.... The chassis numbers for the tisa's are known. It would be interesting to find out for sure.
To my knowledge the only BMW's that came with weber carbs stock where the 18000tisa and CSL's.
