whats up H-T. i got a Z6 with an auto Y8 intake mani. my question is scince it came out of an auto it is set up for a EGR. could i make a cap fpr the EGR port and still run fine?

 

ya just cap it off youll be good to go

 

Also, if your car is a manual then you gonna have to drill out holes/tap for the iacv on the back of the intake manifold and change out the throttle body for an manual one.

 

I have a Y8 mani in my garage that I'm planning to use; I didn't know to ask if it was an auto or manual until after I purchased it. Can someone please post pictures of the difference?

 

nah its already go the IACV on the back. ill post some pics up a lil later to show u guys

 

there no way if the manifold came out of the automatic car, unless some previous owner swapped it out before you got the car.

 

auto

manual

 

nah look.....

 

look how crooked that IACV is..... it has been modified before you owned it.

 

if u look again ull see that it has one bolt holding it on very loosely. i need to buy all new bolts for this swap

 

lol duly noted.

The only thing i can see being the case is (if those holes are factory) that is was an obd2 (jdm) d15b intake manifold.

 

its a y8 mnifold though isnt it?? thats what i wa told. thats where i was confused. it has the IACV and factory machining for that sensor but it also has an EGR system also so it threw me off

 

in the sense that it was unbolted from a d16y8, no it isn't a y8 manifold.

but.

in the sense that it is the same casting (plenum/runners) then yes, it is.

 

ahhhh ok i see what u mean. thnx

 

since tha back of the mani says P2J
Asian 3 stage vtec mani
d15b7 obd2 3 stage vtec

 

^^not b7, just d15b.^^

They didn't add a number after the engine casting in the asian market.

understandable. being that we live in the usdm the 7 likely just comes out as part of the code.

there are alot of differences tho. the jdm 1.5L blocks are nothing like the 1.5L blocks we get in the b2 and b7.

Edit: It's nice that you took the time to cross-reference that for us tho. I had already replied that it *might* be a jdm d15b manifold and now you've basically comfirmed that.

 

wow, I stand corrected then. I never seen that intake manifold before with the egr and the long strip plate on it.

Here's mine,
