does a B16 throttle body of an SI would fit into a D16Z6 intake manifold?

No, IMO... On the d series there are 2 bolts that come out of the intake manifold and go through the throttle body to hold it on then you screw two more in from the throttle body side. On the B series all 4 come off the IM. I'm sure it will fit with minor modification but not worth the headaches of possible idle issues. I'm almost posative the mod can be done. Is there benefit that makes it worth it? NO. I would just take your current throttle body and port and polish it. Then port match your intake manifold. This will save not only money but headaches as well. Happy Tuning!!!

Its a direct bolt on. Be sure to use the TB gasket that matches the TB.

I believe your going to run into problems where the TB bore is going to be bigger then your mani bore??? Thus you are going to be letting more air into the TB but its going to bottle up at the manifold because the TB bore is bigger then the Mani bore.......meaning you are going to need to port out the mani. Correct me if I am wrong. B-series TBs are interchangable with D-series

well for a matter of fact it does fit, all honda TB fit on any motor, and most of the time people swap them like this is in hopes of someting bigger, and the b16 is bigger then the d16. one thing you might run into is vacum line run in different locations it might help to have a b16a throttle body from the same year as your d16 or at least like OBDI or OBDII or OBDIIb

I knew it would be a direct bolt on but wasn't sure if the D series bolts would clear...

I would suggest doing a port and polish on the throttle body and port match the first 2-3 inches of the intake manifold to match... Check out the guys at motorsports abrasives, they have tons of port/polish materials for automotive use. Their website is http://www.sa-motorsports.com

I have a b16 TB on my z6....no probs. direct bolt on.

the only TB that isnt universal is the CX one.

its a direct bolt on, but port match your manifold for better results.

What ^ said. Otherwise the intake manifold opening is going to be a bottleneck on your air flow.

menkio

it will be fine.

no d series to to d series and b series to b series and then f series to h series

T S R Performance

b series TB will fit a d series intake manifold

Jokerluv

YES

they will bolt up, but YES, you wil need to port match the intake manifold.

i gotta B16 one but it doesnt have the map sensor on it..does anyone esle have this problem

btw.. its a jdm B16a one will this still bolt up to a d16 manifold

Krayzielix

anyone?

I really hope you're joking, they're called studs and you're wrong...And my b16a2 in my Si has 2 studs and 2 bolts...studs can be easily removed with 2 nuts...and put into the new manifold the same way.

Krayzielix

can anyone answer my question??

If you are FI, will you still need to port match?

I know that sounds like a stupid question, but it seems like it would force it to where it needs to go... lol I'm an idiot

hehe, but obstruction of flow is still ... obstruction of flow

How big is the stock D16 TB and the stock b16 TB?

kommon_sense

d16=56mm, b16/b18=60mm. So about 15% increase in size of the opening.
