Are there any new 13B rotor housings available for the 4 port motors? Also, if I had a bad side iron, can I get a new one or are they no longer available?

I realize that the 4 port intakes rely on the side housing design. Just want to find a couple of rotor housings that will work with that set up. I don`t know a whole lot about the 4 port motors. Please don`t beat me up too badly asking this question.

 

I know that the -SE housings are still available, and all housings should technically be usable if your willing to send them out to have the coolant ring grooves machined into them

 

All 13B rotor housings '74-85 are interchangeable in that you can make a 4-port 13B with them. Obviously the carbureted applications won't have the oil injection ports and the exhaust port changed several times.

Of course, GSL-SE rotor housings are hard to find, too.

Side housings are interchangeable with 12A. I'm fairly sure that for a given year, they were actually the same part number too.

 

Thanks folks!
Learned something new today!

 

I got two sets of clean oldschool 4 port rotor housings,and also a pair of useable gsl-se rotor housings.
They are all for sale,if interested pm me.

 

no they are very easy to find, they are just hard to pay for.

 

Exactly, I got 4 new ones in the closet and my wallet still hurts.

 

You sure know how to make a rotory enthusiast drool!

 

i want to make a closet joke so badly, but you're lucky!

 

Yah, I think when I run out of rotor housings, it's time to go B6T. It'd be cheaper to do that than get new rotor housings and used ones are just about impossible to find.
