I am looking for a picture of a RE port next to a REW port. Can the REW port be opened up to RE size?

Thanks.

 

Yes you can enlarge the runners, there is the same amount of material available for removal.

20B guys do it all the time to use the 13B-rew rear iron in a 20B build for the engine mounts into an FD.

 

Thanks. Does anyone have a picture of them side by side?

 

Yes it can.

 

Check out this Thread from a few years ago.... https://www.rx7club.com/showthread.p...t=REW+iron+20b

Its weird digging up an old post and the info you need was posted by a Rotorhead that passed on like GuitarJunkie or Blake... RIP fellas
Don't thank me, thank Dave

 

Does anyone have a RE iron laying around they could measure for me? All i need is the height and the width of the port runner where the intake bolts to the iron.

Thanks in advance.

 

Starting from the center and moving up, RE and REW ports have the same height width and position. The bottom is where they are different, the RE port goes down about another 3/8 inch or so.

They have compatible manifolds, all the manifold bolts line up and the ports line up top and sides but bottom, the bottom of the rew manifold can be port matched nicley to the re ports.

The re secondary runner openings are 63.46mm tall, the primaries are 53.9 mm tall, they taper strongly on the top.

 

You are great! That just happens to be where i need it to be bigger.

Thanks
