I was on eBay today and was thinking has any one ever bought one of those civic sheet metal intake manifolds and cut the flange off and welded up a flange for a Miata? If not then if some one has a civic manifold could you measure the runners to see if they come close to the runners on a 99 Miata?

 

i have a picture of the runners search my mane its one of my for sale threads i didnt measure them i just put them next to eachother its definetly do able i still have the intake if you want it, you would need a flange though

 

 

you could probably just fill in the holes and re drill it too

 

Thanks for the pic and how much do you want for the manifold

 

Also if you cloud take a better pic of it that would be cool i hope i dont sound like an ***.

 

Wow. Is this for real? I mean, we're actually talking about taking an OBX manifold made out of thin sheet aluminum for a B16 engine, cutting the ends off, and welding it to the cast head flange of a Miata engine?

 

No im having a flange made if i end up buying one. My friend works at a mechine shop so he could get me real good deal on the flange.

 

It's been done using the Edelbrok IM. IIRC, the flange is cutoff and the miata one welded on. There are two examples of it being used on this site. see CEO's setup.

 

Thanks for the help but when i look up CEO's nothing comes up with that name.

 

It's just: CEO

He posted today actually.

 

Thanks

 

i sent you a pm ill see if i have more pictures
