y8 mani onto EF???
I did a search and found nothing so lets clear that up before any smartass wants to comment about that.....anyway I remeber seeing a website with a writeup on how to put the y8 mani on a mpfi ef (si/d16a6) and was aondering if anyone knew of such a website or writeup......any help is greatly appreciated. Thanks
I believe the Y8 manifold will fit. I believe it also flows way better than the D16A6 and even the D16Z6.
I think you can even use the B18 or the ZC throttle body to increase flow. I think you will have to port match it though.

The site on the link was "temoroarily unavialable" so I will list things from each motor you will need from my memory.
From the d16y8 I used:
Fuel rail, fuel pressure regulator, throttle cable bracket, coolant hose that runs through im back to the block(on the tb side and does a U turn), and all sensors.
From the d15b2 im I used:
intake air temp sensor and that's it.
Problems you might run into:
My fuel return hose on the car was too short and also a different inside diameter. I jerry-rigged it so it's safe and long enough.
In order to make the intake air temperature sensor mostly functional I had to trim the tabs off of it with a dremel and slip a large hose over it and step it down to a size that would fit one of the extra ports on the IM.
If you have any other questons post them here and I'll try to help the best I can. GL
