Ribs type intake manifold for 3.5 FI conversion: what are the parts needed?

[Bmachine]

As I am gathering the parts for an upcoming conversion, I may have a line on an intake manifold from a wrecked late '70s 7 series.

Are there different versions of those D-Jet type manifolds? And which are the "correct" parts I would need besides the 6 C pipes, the plenum, the throttle body, the fuel rail and injectors?

What is the going rate on a setup like that? I looked in the Parts section but did not see any recently.

I'm definitely curious about this as well. There are a few for sale as of late. I have a local buyer interested in mine but I want to offer a fair price. I've heard a number thrown around, but I haven't researched sales to back it up.

wasn't the 7 series L-jet?

Bo,

What kind of motor are you building? Don't think you want D-jet parts.

Just a regular late 80s m30b35. Nothing fancy. I just want the ribs type intake instead of the octopus one.

Seems like I paid $200 for the C pipes, manifold, and TPS. I think that ws more than a year ago

Do I recall correctly that there was something discussed on some Forum about using 6 pipes from a certain model of 2002 to get better performance??

IF so, you might want to pursue that for the engine you are using.

the diameter of the C tubes from the 320i is bigger. this is what most people use.

The length of the 320i tube is different.

The length of the 320i tube is different.

But they can be used? I'm also considering a M30B35 swap in years to come.

 

[HB Chris]

I used the e21 C Tubes, more low end torque I was told but all you are doing is moving around where it occurs.

Excellent info! Thank you Don!

Resurrecting this thread.

To use the B35 harness but using the E12/L-jET injectors, you just need to change out the clips so the harness adapts to the older injector type?

Or is there an injector out there to can be used w/the B35 Harness clips and older L-Jet fuel rail? VW Vanagon injectors maybe???
