hello there, its been awhile since ive been on here. i have a 1997 civic lx, d16y7 of course and im getting ready to do the d16y8 intake manifold swap. Got an automatic y8 manifold for cheap and while im swapping it i am picking up a thermal manifold and throttle body gasket. Now my question is, are the y8 automatic and manual throttle body gaskets different? i checked advanced auto online and noticed a little difference in the gaskets but id like to find out for sure. Thanks!

 

I think they are different. Auto y7 and auto y8 tb gasket are the same I believe. At least I think they are, from reading this guide.

I have gather all parts to do the swap on my 98Lx. Just waiting for warmer weather.
I am using my stock tb with the tb rotor from an auto y8 tb.. Everything you need are in that link. I would read through all the pages. Very clear guide..

 

yes just figured that out y7 and y8 auto are the same. ive read through many swap guides, thanks for the heads up but i think im just going to use the y8 tb since i have the auto manifold.
