Hi Mihnea,

I was referring to the air conditioning compressor location,
which is not affected by cross-flow head or not, AFAIK.

I think you are referring to the turbo.  I was asking if the
turbo was in the same exact "location" as the factory turbos,
not simply the same "side" of the motor.  In other words, I
know the Callaway turbo is on the exhaust side of the motor,
but is its location "exactly the same" as the location of a
turbo in the stock application.

On the MC cars, the a/c compressor is on the left side,
opposite the turbo.  On the normally aspirated Coupe GT and
4kq's, the a/c compressor is on the right side, around where
the turbo would be.  I believe there is probably interference
there, so that a turbo couldn't co-exist with the a/c
compressor on the same side of the motor, at least with the
stock turbo EM.

I was wondering if the Callaway EM puts the turbo in a
different location, on the same side of the motor as stock, or
if it puts it in a different location, that doesn't interfere
with the a/c compressor (when it is changed to a smaller
Sanden unit)

Another way to ask this question would be:  If I have the
smaller Sanden compressor on the (stock) right side of the
Coupe GT motor, can I bolt on a stock turbo EM and fit the
turbo too?

I already have a 2B bent tie-rod, a 1-pc manifold with some
cracks in it, a 2-pc manifold, a "regular" K24, and am working
on another 2-pc manifold.  To get the turbo diesel manifold
would require buying more stuff (not to mention "not using" my
existing stuff, which I want to avoid).

I would like to know more about being able to use my existing
parts.  Namely, can I bolt on an MC manifold the same as a
Callaway manifold, and possibly change the a/c compressor to a
smaller Sanden version "while keeping it on the same (right)
side of the motor".  The alternative would be to put the whole
MC motor into the Coupe GT, which is more work of course.

Thanks Mihnea.  I think you slightly misunderstood my question
tho'.  (reminds me of yesterday's question re: voltage
stabilizer "repair"...)

I do appreciate (almost) all responses tho'. :-)

Later,
