A couple of my employers work trucks have 14B engines, their exhaust manifolds look very similar to the Isuzu 4BD1 pattern.

Here's a picture of an Isuzu manifold. Can someone measure up a Toyota 13B or 14B and see what the differences are?

I could measure a 3B manifold. Which is the same as a 13b-t... As my old 3B log is still kicking around... will that work?

Sure, that'd be great if you could.
 
Nice work on the mechanical drawing dougal. Also nice to see you here on Mud!

Cheers Bram. part of that will be on the CAD model I'll send you (hopefully tonight).

Any updates on the measurements?
 
Ah forgot. Calipers at work. Will measure tomorrow.

Can you put letters next to your measurements, such as A, B, C etc.

Then I will note the measurements of the manifold I have.
 
i work in an isuzu diesel shop, we THROW OUT similar looking manifolds a few times a week when we refit new isuzu crate engines with marine manifolds.... they ain't cheap, we just have way more than we'll ever use.

some one get me some measurements off a 3B and maybe i'll have some good freebies to hand out!

If they are Isuzu 4B manifolds (4BD1, 4BG1 etc) then I could be interested in buying one. PM me when you know.:)
 
will do!
 
So, do anyone have 3B exhaust flange dimensions?
