Turbo conversion in coupe quattro started...

[JShadzi@aol.com]

	I mentioned a while back that I would be doing a MC in a 90 coupe 
quattro, well we started today.  We found a 87 5000 quattro that had a front 
end wreck, not too much damage but enough to total I guess ($500!).  We began 
pulling the engine and marking all wires and vacuum lines this morning, and 
we are ready to drop the motor.  The front bumper and radiator support are 
out so it's just a matter of rolling the motor out on a dolly.  Next step 
will be to get in and remove the harness.  The game plan is to map out each 
wire's destination from the ECU and match it correspondingly to the coupe.  
There will be some complications, I'm sure, because the coupe is EFI and the 
fuel lines come out in the middle of the fire wall.  Here are some problem 
areas I foresee, your suggestions are appreciated, especially BTDT?

-The AC, yes we want to keep it, but the alternator and compressor are on 
opposite sides.  The hope is that we will be able to swap brackets to the 
original coupe location.  That just sounds too easy though, it will be trial 
and error.  The coupe radiator comes way down blocking the alternator, and 
the turbo is right there on the other side...

-Intercooler.  Behind the grill seems like the only place, but space is tight 
(serious customization) and it seems like the second radiator will come in 
handy for the water cooled turbo (any thoughts?).  The RS2 bumper is the 
easy/expensive solution ($900?).  If you have seen the ND turbo for the VW, 
they put an intercooler underneath the hood behind the radiator.  A compact 
Corrado IC may fit with custom pipes there?  

-Like I said earlier, the fuel lines are in the wrong place.  We still need 
to see if there are any differences with the accumulator and fuel pump and 
appropriate changes there.  Bending the lines may be the easiest way to get 
them where we need them...

-Wiring.  As far as I know, this should be pretty straight forward, just 
identifying wires and making sure they go to the right places.  We may try to 
avoid rerunning wires and just splice existing wires into the coupe harness 
that are redundant and already where they need to be.  

-Climate control.  Ersatz S2 web page said that they had trouble with this, 
but I'm not sure how it ties into the ECU as of yet.  The manual system will 
be an easy choice is this step causes much trouble.
	I plan on giving you guys updates as we get along, and I would love 
your ideas, cautions, and suggestions.  I know this is EFI to CIS, but you 
CIS to CIS swap experiences will still be a great help...  ;)
