Intake manifold options for zc

[91civichatch]

Does anyone make an intake manifold for the zc? I saw on ebay there was an adapter plate you could buy to fit a d manifold onto it but it was way too much for me. Anybody heard of modifying a b18 manifold to fit? or am i just gonna have to port this one? also will a d or a b throttle body fit the zc mani?

i think the b series tb will fit on a d series intake mani

I believe the inlet manifold off the EG Si Anniversary Edition throttle body bolts straight up, which then allows you to run any b, h series etc throttle body. As for after market, dont think there is any is there??

Yep he's right ^^^ (Hi Randall)
Any OBD1 ZC manifold will allow for B & H series TB's. They can be easily identified as they dont have the PGMFI sticker on the top and instead have two or three ribs. They will have the casting code P29.

Be aware thought that the OBD1 ZC's had the IACV valve on the bottom of the TB so there is no place on the manifold to bolt on your OBD0 IACV.
If you use a TB with an IACV valve on the bottom they dont have the electrical sensor connector on them that the OBD0 loom has.

but if they were more common, hell ya!
i think the b series tb will fit on a d series intake maniNO, not every IM has the same TB pattern...

zc speed makes a adapter plate so u can bolt single cam mani to dohc head.

I know that you can't mount a B series TB onto an OBD0 DOHC ZC mani....I know on the OBD1 you can as was stated above... does anyone know what kind of performance gain or loss you get from using the ZCspeed adapter plate??? I was thinking about it since I still have my Sohc D IM and want to run a B series TB on my engine...
