John,
It sounds like you have the turbo block. The round inserts that line
the exhaust port are common to both the turbo and NA blocks. But, only the
NA blocks have the anything in (across the direction of flow) the exhaust
ports and they are the sort of rectangular looking pieces that run from wall
to wall about. I have a turbo block with high compression rotors and love
it. Although, I must admit its a bit on the loud side without a turbo to
breakup the exhaust pulse.

Ed and Finn; The engine that I have, I purchased from Atkins Aviation and
I
don't know much else about it. Looking in the Haynes Manual there is a
picture of some rectanglar metal pieces in the exhaust ports. Are these
inserts used in the turbo engines, at any rate the engine I have doesn't
have those . There appears to be some nearly round inserts in the
aluminum
rotor housing, I assume these may be peculiar to all 13B engines.
Thankyou
for the info. Next week i'll have to do some price checking with some
different vendors and go from there. JohnD
