Subject: [FlyRotary] Ideas for dir= ect injection

I'm struggling here on which way to go, so I'm = hoping maybe you guys can help me sort it out.

My problem is that wh= en building my intake, I pointed the injectors the wrong way.  My poor= thinking was that it would allow the fuel to vaporize better.  It was a nice theor= y to mull over while petting my unicorn.  In practice, all it does is = allow fuel to pool in and cause condensation to form on the manifold. = I have to fix it, but I'm torn on how.

1) Direct injection.  O= n the 13B housings, the oil injector port looks like a good place to instal= l the injectors.  The issue is that the hole to the chamber is very sm= all.  I'm thinking I would have to drill it out to get a spray into th= e chamber, and I can't think of any safe way of doing that except to comple= tely disassemble the engine (Ugh!).  There is a  brass fitting at= the bottom of the oil injector hole that looks like a carb jet.  It tried to screw it out, but the thing won't budg= e at all.  The other issue is bolting the injectors down.  The in= side diameter of the screw thread of the oil injector hole is .007 less than the outside diameter of the stock 460cc injectors without the pl= astic cover on the tip.  I thought about using a die to put threads on= the injector tip and screwing it in.  The injector's plastic tip has = a recess which would provide a nice seat for an O-ring, but .007 doesn't gi= ve a lot of bite.

So the two issues with direct injection are a)how = do I open the oil injection hole up without disassembling the engine or get= ting swarf in the chamber and b) how do I secu= re the injector.

2) Build a whole new manifold.  Does anyone ha= ve a spare 6-port manifold that I can cut the flange off of?

2) Cut = up my current composite manifold up and move the injector placement.  = I've already made a couple of "adjustments", so this thing is already getti= ng ugly.
