Okay, so, is there any schmuck throwing together a two rotor engine using 20b housings? I mean, the port sizes are so much bigger? Why the hell not!



Thoughts.

behold the 13b cosmo engine!

I'm a noob https://www.nopistons.com/forums/pub...#>/biggrin.png

There's one sitting at the shop..should i buy it?

Man you can't even afford new underpants, I wouldn't buy it.

Kidding me.. how much bigger are the ports on the cosmo flavored Rotary? Someone post pics.. suddenly the stoned one is intrigued... https://www.nopistons.com/forums/pub...DIR#>/spam.gif

Whoopass.. I finally just got done reading the 13B RE sticky in the 3rd gen forum.. its shitty the ports on the exhausts came smaller... they can at least be bored out like the 13B REW motor right?

No, apparently the exhaust sleeves are hollow. You need to replace the sleeves with FD ones. I hear its a pain, but check out the rebuild forum for more.
