I'm looking to run a four line OMP on my motor when I rebuild it, but I am having a hard time finding an -SE OMP that is in good, working condition. I have found several S4s. I'm running -SE housings on my 4 port 13B, and I was just wondering if I could safely bolt up an S4 OMP to my 12A front cover with -SE housngs.

 

I think they do. The only problem might be the mounting bolts. Unless the lobes are worn on the SE one, they can be rebuilt, don't remember the site that sells them though. Vipernicus42 does.

I was just looking in there, and I actually posted when that thread was first started. Didn't answer my question, though.

 

S4 OMP bolted right up to my old GSL-SE front cover.
The output of the SE v/s TII OMP might be different,but the mounting pad is the same.

 

tee hee I just recommend you premix.

 

Do you premix yourself? I do and find it a royal pita. On a do over, I would leave the stock mop system intact and functional or go with the Rotary Aviation setup.
