iv got a spare one. i wanted to know if this TB is bigger then the a6 TB if so would it fit on the a6 manifold? im guessing it would since there both D series intakes. im swaping in an engine soon and might want to fool around with my d15b2 a little before i do anything.

 

just so no one thinks im retarded.. iv got an mpfi swap on my b2

 

the 88-91 DOHC ZC uses the same throttle body as the 88-91 D16A6 and the same as the 88-89 D16A1 - it is 55m and they are interchangeable between those engines - no other D-series throttle bodies will fit those engines without swapping the intake manifold

 

no other d series TB fit? then why have i read people using ls TB on d series engines? but thanks for the info.

A DOHC ZC Intake mani is not the same as a SOHC intake mani. A DOHC ZC TB will not cross over to a SOHC mani. NO SOHC TB will cross over to a DOHC ZC mani.

You can use a LS/B16 TB on a SOHC mani, the pattern is the same.
The only TB that swaps to a DOHC ZC is the D16A1 from the 88-89 Integra

You can get the DOHC ZC TB bored to 59mm if you want a bigger TB. I've had 2 of them done with matching intake manifolds and worked great

 

ya i know the dohc intake manifold is different from the sohc ones. i dont really care that much to get a bigger TB i was just wondering since im swapping in a new motor next month. just wanted to fool around a bit before i did it.
