'89 200T block question

[Hoffman Anthony J A1C 552 CMS/MXMVC]

On one note, The non-turbo uses cast pistons and crank, so I wouldn't
turbocharge this. I also believe it doesn't have the oil squirters. 
On another note, I have a pamphlet with all the engine codes with HP and
compression through about '91, but I'm not sure about bore and stroke. I'll
check and get back with you.

Subject: '89 200T block question


Thanks for the responses, all.    Sounds like things are not immediately
going to work out that well between the donor car ( '89 200T) and the
patient ('89 90q).  I also have at my disposal as far as engines go:  '83
5kT- 2.1L turbo.  '84 4kQ.  I wonder if there is a combination of
head/block/pistons (and rods/crank etc) from the four cars that would
assemble into a usable turbo engine, using the MC-2/MAC-14 engine management
system.  It seems like I have a lot of parts that _should_ go together in
some way, but maybe not in a practical form- example: the high-compression
90q engine with turbo induction and engine management parts from the 200t. I
know this has been discussed here before, but what experiences, if any, has
the community had with turbocharging the high-compression engines? Seems
like the boost would be very low in order to avoid massive pre-detonation
problems.  What about finding low-compression pistons for the 2.3 block
(90q)?  Or putting the head from my '83 turbo on the 90q block, and using
the mc-2 manifolds and engine management.  I can't remember what the
compression is in the '83, and whether the compression is controlled more by
the piston profile or the combustion chamber volume.

As a side note, does anyone have a complete table of the engines that audi
produced over the years, code designation, precise displacement and maybe
some bore x stroke info?  I've found some partial tables, but nothing yet
that is all there.    

Thanks again folks.

Charley
