RS2 Competition Turbo - again

Not again..... (Jimmy, please put this up on the FAQ)

Take a RS2 turbo apart, then a "7200 comp" apart, there is a difference.
Cold side housing and turbo wheel are different, BTDT.  Basically, if you use
whatever KKK's numbering system is at the time (I did this back in 94 - at
least 2 numbering systems ago), you will find that the cold side wheel is
larger on the 7200 Competition.  The RS2 'Competition' is actually and
ascribed misnomer, as the "RS2 Comp" really doesn't exist.  What does exist
is the "7200 Competition".  Which is EXACTLY how KKK delivered the RS2 hot
side housing, RS2 hot side wheel, and RS2 "+1" cold side wheel and housing.
KKK also labelled the box it came in "7200 Competition".  I know this, cuz I
sold about a dozen of them when they were available.

The easist way to tell the RS2 plane jane from the 7200 Competition is that
the plane jane comes with the audi tag on the cold side, the 7200 Comp
doesn't come with any tag on the cold side.  The hot side housing and wheel
will carry the same part number, so will the center bearing section (it
should they are both k26 derivitives).

There is also another cold side (wheel and housing) that is larger than the
7200 Competition.  I currently run 1 of these in my fleet.

Everyone has "opinions" on these turbos, and it would appear it's shrouded in
grand mystery.  I laugh, KKK knew what that hot side was (awesome), and (my
guess)kkk  was likely restricted in using a porsche/audi proprietary "RS2
Turbo".  The rules have changed since, because the only way to build a 7200
Comp these days, is to order the RS2 turbo complete, and add larger cold side
wheel/housing.  Bringing full circle what I did to my first RS2 turbo in
1994.

I share the opinion of many other listers - there is no such official
Audi part.

Audi dealers in Germany have not heard of it.

Jo Hoppen says such an official thing never existed.  He says it's
probably a name that was put on "something" by some tuning shop to
make it seem semi-official, and better than RS2.

You surely know how that marketing thought goes ...  we'll call it
a "gizmo plus" and it'll sell better than an original "gizmo".
That's not to say that some tuner's turbo hybrid isn't better than
a RS2 turbo under some circumstances.  Much of turbo tuning is a
compromise, so read the fine print carefully ...  be sure to ask
for the fine print so you can read it.
