Stock intake on 82 12 A
1 Attachment(s)
Need Help. I am going through my '82 and have a question about stock intakes. I have attached a photo of my stock '82 manifold and also of an intake I was given along with a Nikki Carb I purchased. My '82 has a butterfly as part of the intake, circled in the photo, the other intake does not have this valve, seems much simpler. I am removing the "rats nest", so my question is can I use the intake without the valve? What is it for? Noticed a difference in the water jacket as well but the bolt pattern is the same. Anyone ran across this? I appreciate any feed back.
I have also picked up a complete dasd from an '84-85 model, anyone ever switched one of these into an '81-83 model? My dash is in rough shape and needs to be replaced. Would like to go back to the '81-'83 style but seems difficult to locate with no cracks. I have an '83 dash but it is also split right above the instrument cluster, Thanks, Jeff Morgan:scratch::scratch::scratch::scratch: |
Shutter valve... it stops the little spits of backfiring on deceleration. Ya don't need it if you're removing the rats nest / emissions.
For more info do a search with that term. |
My car backfires less without it. lame as shutter valve.
|
Looks like you have a pre-RX-7 intake manifold.
|
Nope that's very much a '79-'80 RX-7 intake manifold. You can't use it because it lacks the casting to cover the ACV port below the primary ports. You can use it, if you do some things first.
|
Thanks for all of the information. Is there any problem if I pull the shutter valve out of the '82 intake as long as I plug off the air lines associated with it?

it also breaks and kills your rear rotor :]

I removed mine and plugged the hole left by the valve shaft, using a part of the shaft itself as a plug along with some good ole JB weld to hold it snugly in place.
