I haven't dealt with RX7 stuff in quite some time, so I don't remember...

The picture I have attached is for of an upper intake manifold for a weber carberator application, but can anyone tell me if this upper intake manifold would bolt to the lower intake manifold of a 6port engine or a 4 port engine... or both?

Thanks!

 

Looks like it's for a 6 port.

 

6 port

 

if it has 2 holes on one side,then its for a 6port 86-91.

 

Does anyone have pictures of a 4port intake and a 6port intake?
I am just curious as to the differences on the bolt pattern and the runners.

Thanks!

 

I actually do. Which would you want to see s4 or s5? I have both n/a. But I have a s5 jdm lim i'll take a picture of as well. The difference is how much the runners are spaced apart.

 

Would it be too much trouble to post a picture of both? Id just like to see the difference in order to expand my education

Thanks!

 

you guys are wrong. thats RB upper intake manifold for a sidedraft.it bolts up to the stock LIM

 

I found some pics of both the 4port and 6port lower intake manifolds, and you were right, the racing beat UIM is for a 6port LIM.

Thanks for your help guys, your awesome!

 

^^ Ya it is for a 6 port. Of course, but op wanted to see different. Let me know if you still want pictures. (For ***** and giggles)

 

Im good, but if you wanted to for fun incase someone else is looking for the differences.
