Is there any difference at all between a B7 and a Z6 manifold?

I ask because my d15b came with a manifold that I couldn't use, so I re-used my b7.

I am wondering if I have something not working right because of this guy saying that he plugged something on the Z6 manifold to put it on a B7. So, if I put a B7 manifold on a essentially a Z6 head, do I have a problem?

there is one water nipple that has to be plugged, not sure exactly since it's been so long.

Yes there is a big difference in the intakes, can't wait to get a Z6 manifold on my B7!

Why could you not use you D15B intake?

Pics please, but I'll be gone till Monday, tranny delivery out of state this weekend.

Do you guys know what that tube flows? I assume it's coolant....

There's no way this could have something to do with my car not engaging vtec does it?

I can't remember the exact details, but I think the throttle body had different sensors on the D15b and there wasn't a few other details. I'll pull out the old manifold and take some pictures when I get back to my car in a few days.

i assume you have a D15B that has VTEC? If so, it wouldnt have anything to do with it engaging that i know of. VTEC engages with oil

Bone, here are the pictures. I'd have to take the B7 manifold off the car to compare any further. From what I see, the D15b throttle body has a map sensor on it and the tab on the back side to mount that black thingy isn't tapped, so I didn't use it.

D15b manifold

The tab between runners 1 and 2 is not tapped.



B7 manifold on the car (notice the black canister thing that is mounted to the intake, next to the vacuum hose)

the purge solenoid can be zip tied to the intake, is there a hole even?

Map sensor will be fine, just need to unravel yours from behind the fuel filter and it will reach, or reuse your TB with a new gasket which is only $5 from NAPA.

there is one water line that is an issue. I don't agree with the above plugging. I'll have tyo make my own writeup when I do the swap.

Sadly I might be dropping the D15BEAST7 from the HB into the 4 door, will need alot of pics!

Yeah, things look a lot simpler now that I know more about Hondas than I did 3 years ago.

The tab on the manifold doesn't have a hole. I'll probably just drill a hole and zip tie it, or drill and tap it.

I'll swap the throttle body too.

I wonder if there are any other differences that I'll find when I take off the B7 manifold.

i just put a z6 intake manifold on my b7 last night...it was pretyt much plug and play
the only difference was the z6 tb was set up for a firewall mounted map sensor, so i had to reuse the old throttle body
That other tube that you guys are saying has to be plugged runs to the iacv

this tube runs to the iacv...
the other tube above the main coolant line is the one that runs through the stock intake tube
