Bill,

This is good info and would save having to make the adaptor block = for 2=20 stroke oil, that sits on the spark plug side.

I must say that the compressor making better atomisation , goes a = long=20 way in changing my mind about direct injection.

Isn't that what Mazda is doing with the RX8?

Now if you have an idea where the best position to place the = injectors, I=20 would like to hear about it. I'm a bit concerned about the injectors = being in=20 the way of the manifold tubes.

No rush, I'm happy to wait for the info - it all takes = time!
