Paul,


I have some scrap 13B housings now and I still can't imagine where to drill
the hole for a third plug that won't end up letting water into the engine.
It seems the only possible solution is to braze some more aluminum into the
water passage and then to drill a small spark hole down through the filler
and through the stainless liner.  Next the hole plug hole needs to be
enlarged  and tapped to except a spark plug.

I think the R26B housings were probably specially cast. It would nice just
to find a few of those laying about my friend's shop.  That and a linear
bearing slide throttle and water pump.  Ahhhh  yes If pigs could fly:)

Notice how the injectors which appear at location #1 are located and angled
down just before the slide throttle. In item #2 it appears  high pressure
lines are coming  from the tubular fuel rail and heading towards some other
unseen injectors which if like other racing applications we have seen, are
installed directly into the housing above the intake P ports.

Somewhere on the engine top beneath all of the  clutter and behind the water
pump is said to reside an oil reservoir. I can't imagine where.  It looks
more like the whole front housing is a large reservoir.

What kind of file was that Doug? It had no extension
and it was not a jpg, gif or doc file.

What you do is bore a hole in the rotor housing for a solid
cylinder. tig weld it in and then machine a spark plug
hole. Or if you don't want to tig weld it in thread
the hole and thread the cylinder and screw it in.
Seal with high temp epoxy. JB weld will probably work.

A lot of work for less than 3% better BSFC.
Have you given up on the 20% better turbo compound?
My turbine gear box is close to being done. We had some
set backs in the grinding process but things are moving
along somewhat slowly now.
