y7 manifold to y8

[y8vtec423]

ok im swapping my y7 manifold to a y8 i need to know what all i have to do. can i used my y7 tb or would it be easier to just used the y8 tb. how do i run the vaccum lines because i know the y8 has more of them.

is this because the cat is in the manifold on the Y7

 

[y8vtec423]

i should have more more specific i meant intake manifold sorry

 

[airzi]

do you have an aftermarket air induction fitted?

easiest route: use a y8 AUTO manifold and a y8 AUTO throttle body. that way your IACV setup will be the same. had that set up on my old y7 and it worked great.

also: so much information under your nose you didnt even have to start a thread

thats the thing i have to go to a 2 wire because im boosting it would i just be able to use the 5 speed manifold and auto tb and just not connect the other iacv

yea in that link i posted it says you can use the 5-spd manifold.

5spd setups have a iacv on the back of the manifold, while auto setups have the iacv on the throttle body

if you plan to use an auto tb with it then you will still be using a 3wire setup and have to block off the iacv opening on the back of the manifold.
if you want to use a 5spd tb then you'll be using a 2-wire setup and youll have to get an iacv for the back of the manifold
