ive read that there may be issues with fitting a 99-00 d16y8 intake manifold on a y7 because its different than the 96-98. at the same time ive read that the auto intake manifold is the ideal one to get. so, what about the 99-00 auto intake manifold? is it still an easier swap?

 

Get the y8 manifold from the year of your y7 motor. I have an auto y8 99-00 manifold with almost everything you'll need if you want it. I was going to use it for my 99 y7 motor, but I ended up doing the full mini-me head swap and couldn't use the auto manifold anymore.

Only issue with the 99-00 Y8 manifold is the air injection holes. No major issue, you just need to plug them up. Get some small set screws, a tap and some rtv, and you got a 5 minute job in front of you.

If you plan on staynig with your non-vtec Y7 head, and running the y7 ecu, then an auto manifold is ideal. However if you plan to swap a vtec head onto your block in the future, get the manual version, and the IACV with it. It will not do anything unless it is plugged up anyways.

 

If you can get the auto cheap enough it will be a great easy swap for you, and later if you change ecu's or put VTEC head on the manifold can be tapped pretty easily for the 2-wire IACV. That's what I did, I have both IACV's attached but right now I just have the stock Y7 running. When the Y8 head and P28 ecu go on I'll just put the plug in the Y8 IACV and take off the other one.

You may want to be careful here: The Y7 IACV doesn't operate like the Y8 IACV. The Y8 IACV, while being unhooked, closes down and provides no entry for air to get around it. The Y7 IACV is a lot different in construction and operation. When you unplug it, it doesn't close down (and may open even more) which = a vacuum leak. You could potentially have a nasty vacuum leak if you don't do something about the Y7 IACV when you go to use the Y8 IACV.

Not a problem, I'll be removing the Y7 t/b completely and putting the Y8 one on...
