: : I did a little digging through all the docs I can find, and I can't find the reference to 2000TI with 45DCOE's. As WH stated, all literature refers to dual Solex sidedrafts, except the 1800TISA.

: : 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, 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?

: Mike,

: 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.

: Regards,
: WH

Wouldn't the 1800, TISA or otherwise, have a 118 head? Is this 1.8 an engine with the same bore as 2litre and shorter stroke, or the smaller 84mm bore and stroked?
Further triva: the Weber book lists a conversion kit for the 2002 (K205) with DCOE 45s numbered 15&16 (same no.s used on 1800TISA), they show another kit for the 2000 (no kit no.) with DCOE 40s, both #2.Very interesting...
