I'm so close to having my 13b up and running in my FB that it's giving me the jitters. But of course, it's the details that always get me. I'm fitting the heater hoses and have been trolling around the internets for quite a while now and I think I have the answer, but I'm not sure. So there's two metal nipples coming out of the firewall and one is supposed to head to the beehive (which is no longer) and then on to a T coming out of the engine block, while the other is supposed to go right to the T. So I'm thinking I can just block off the upper one and attach the lower one to the nipple on the block and my headache is one step closer to ending with the medicinal sounds of my rotary running. Although, maybe it will be the sounds of a rotary running too hot and the apex seals shooting shrapnel through my dreams. I would like some confirmation on which one it is before I try though.
Anyone have any thoughts?
Thanks

 

There is a long hose that connects from one firewall connection to the T on the motor. Use a cap to cover the other part of the T on the motor.

For the other firewall connection, there is a small bit of hose that connects to a hard line that goes to the radiator. That hard line also has a T, if this was a 12A RX-7. Use the same type of cap to used on the motor T. If this was a GSL-SE, the hard line does not have a T.

Here's a pic that might help.

 

Thanks so much. That is perfect. She will run soon.
