Just to start off, I have searched and found nothing. I got a call today from my dad asking about the exhaust on his rotary. He is in the proccess of rebuilding a S4 n/a motor and i have a question for you guys. He told me that on one of the irons that in the exhaust is a steel peice, but on another there is none. He tells me in 87, they didnt have steel in the exhaust but the 86 did. is it possible to remove the steel within the 86 iron and have it = to the other? Input is greatly appreciated. Thanks again.

 

If you are talking about the sleeve in the rotor housing; they all should have the steel insert.
N/A has a "bridge/diffuser" in it, turbo does not.

 

i was goin with what my dad was tellin me, what can i tell him because he tells me theres not a steel peice? put one in? find a diff iron? whats ur input?

 

sounds like he has a turbo exhaust sleeve or its been ground out. it probably would be a good idea if they were the same but i doubt it would hurt anything. stop bumping your threads

 

thanks for the info, ill let him know, i bumped because i thought one of replies didn't go through, sorry bout that but ill tell him that it really doesnt matter but if he can, get em the same just to be safe, thanks again guys!

 

just remove the other one (grind it out, port the exhaust, whatever) and make them the same...

 

pics?

 

i dont have any pics, im currently going to UTI in ill and my dad doesnt know how to work a digital camera. i asked for some but he doesnt know how to work it do i gave up.
