Rusty,
Why would you need through bolts off a 13B for a single engine ? Sounds like your building a single RX8 ( RX4). George (down under)

 

Hey George,  

 

You really are behind on email.  Been out on one of those walkabouts or something :-)  

 

The plan was to cut the bolts off, and thread the end for a nut.  I understand that the short bolts from a 20B will work, but they almost don't exist over here from what I can find.  As it turns out, I was told by another list member about a guy who had a set of bolts for a single, and I have them on the way now. 

 

I also just got a single rotor engine today that I bought from a guy on Ebay.  It's got bolts of course, but probably not any sort of official 20B parts.  I'll have to pull it apart to see what it's really got inside, but it looks like older housings of some type.  The shaft is a cut down 13B, which looks usable so far.   

 

What are you using for bolts?

 

Cheers,
