engine and drivetrain Help Id Ti Intake Manifolds?

[Henrygabs]

I have some intake manifolds and I'm trying to determine what "ti" model BMW they came off of. Any feedback would be appreciated.  Are there any resources out there to check part numbers?

Thanks!

I don't know the part number differences, but measure the head and carb side diameters of the runner and I will see if it matches my 2002ti diameters

"Swivel" linkage suggests these were off an NK car like a 1800Ti or 2000Ti. 

 

Carb and manifold mating surface  dimensions will give better indication of which model, like Cyclone1 said.

+1 to this.

Thanks for the info, I will measure and post after work.

Cheers,

So I've finally measured.  The diameter of the carb-manifold side ports are 4cm in diameter.  In case it matters, the head-manifold side ports are 4.5 cm x 3.7cm. 

 

Thanks again for your input.

Linkage is NK, intake port shape is 2 liter. Early 1800 engines used a 118 head and the ports are round. In the picture it looks like someone has done some grinding inside the manifolds. They could have taken an early set of manifolds and port mached them to a later 121/E12 2 liter head

I was also confused when trying to purchase some ti manifolds: some were embossed with a BMW logo and parts number (like your top photos), some had an H121 and V121 ID, and others had no ID at all.  As others mention, I would check manifold port sizes for the best fit.

IIRC, the "H" and "V" stands for Front and back (I think Hinter and Vorn in German).  This is stamped on my ti manifolds.

Guten Abend,

 

raised numbers on cast parts do mostly NOT show a part number but just a cast number.

 

There was quite a large number of different two-piece dual carb manifolds either from BMW or lookalikes from other manufacturers. For example:

 

Alpina

 

Heidegger

 

Manifolds shown above should be from NK because of the linkage - I perfectly agree on that. As cast number starts with 118 they are probably from 1800TI. TISA was a bit different if I remember right. And they have been machined to fit the big oval ports of the 2 Liter cylinder heads (sorrowly - original 1800TI is a bit rare meanwhile).

For manifolds for NK 2000TI/TiLux or 2000CS cast number should start with 121 and those do also have the integrated rod for the redirection of the gas linkage on the one manifold. Big oval ports on those ex factory.

 

Best regards, Lars.

Whatca got there is a pair of 1800ti manifolds, one ported to work with a 2-liter head and the other not ported.

[LarsAlpina]

How do you know that second manifold isn´t ported? Not to be seen on the photos or am I wrong?

 

Best regards, Lars.

[mcmil]

Sorry! My bad. I mistook the carb side round ports for the head side. The studs should have been a clue!

 

Still, they are ported 1800ti manifolds.

 

BTW TISA manifolds say TI SA on them.

[jgerock]

NK style manifolds.  2002ti did not have the pivot linkage - only the boss for one.

 

[jgerock]

I believe this is 2002 Alpina with Webers picture. Note the modified ti air cleaner with L-shaped mounting bracket.
