other Thoughts on this 72 tii?

Absolutely, Jim, I'll be there.

 

And I intend to move slowly and deliberately from car to car, inspecting snorkels.....

 

 

We have to get together at The Vintage then. No snorkel here, I have to hold my breath.

The new owner needs to ditch that blue coil or bypass the ballast resistor.  Looks like he's running the blue coil with the ballast still inline === weaker spark...

I bought a black coil from Blunt a few years ago.  A blue one arrived. 

Blunt informed me that "blue is the new black".

Rust or no rust, driving or not driving, snorkel or no snorkel...$12K USD is an absolute bargain for a tii that original and complete. We've arrived at a place & time where one needs to pounce immediately on these opportunities...and ask questions later!

...it has the elusive black plastic intake runners.  Extra cool points for that, as they are only on the earliest tiis.

 

It's a '72 tii... I was under the impression that ALL '72 tiis were equipped with "the elusive black plastic intake runners," no?

Hey, COOP,

 

The switchover from plastic to aluminum intake runners (accompanied by the switch from the 121 to the E12 head, and generally by the appearance of the firewall notch) was in May-ish 1972, well before the first 1973 U.S. tii models appeared in early October-ish 1972.  Rob of 2002haus, has published the VIN numbers for the transition period -- it, like so many improvements, wasn't a single VIN cut-off.  If I can find my bookmark of the appropriate thread, I'll post it here.

 

That is why some people refer to "early" and "late" '72 tii's: it's not a reference to (a.) '72 models manufactured in '72 versus (b.) '73 models manufactured in '72.

 

Best regards,

 

Steve

Thanks Steve! Surprised that I didn't know that...always thought that '72 tii = plastic runners, end of story...

PS: I don't buy it!!

COOP,

 

I kid you not!  The plastic-to-aluminum switchover couldn't wait for the U.S. '73 model year because BMW was having service issues with the plastic runners: both cracking of the runners and miscellaneous other leaks.  The aluminum runner solution was an expensive fix to this problem but even that arrived in fits and starts:

 

See Paul's (wegweiser's) analysis of the switchover VINs based on his experience (2nd post in the above thread).

 

There are lots of longer discussions of the topic, e.g.:

 

Short version: from VIN 2761944 (a May 1972 car and the first U.S. tii with an E12 head) onward, E12 heads, aluminum runners, and firewall notches became the factory's "desired" configuration for U.S. tii's, a desire apparently interrupted by supply issues and resulting in a batch (batches?) of U.S. tii's with plastic runners after that 2761944 cutoff!

 

Best regards,

 

Steve

Paul, they are not the same.

Old Bosch Number ---> New Bosch Number -- Use Ballast Resistor x.x

 

0 221 119 016 ---> 0 221 119 021 --- 0.9 ohm ( old ones were painted black )

 

0 221 119 050 ---> 0 221 119 030 --- 1.8 ohm ( old ones were painted red )

0 221 119 015 ---> 0 221 119 030 --- 1.8 ohm ( old ones were painted black)

I know, I know.  I had this discussion way back with Blunt.  I'd have to refresh my memory, or talk to Blunt, or go check my coil, but bottom line is everything is connected (with ballast) and working as it should.  No issues.

 

I do have the original (black) coil from my car.  Maybe I should put it in and see if there is an improvement in starting, snap, and mileage.

I would be shocked and a little pissed if there was a noticeable improvement.
