Z32 TTVert's Check list of parts to get for an NA to TT Z32 swap.
These are many of the parts I noticed were different between the NA and
TT Z32, when doing my swap.
We're not talking about the motor or tranny, I am documenting all the
other stuff that people don't usually mention.
This is NOT a complete swap list!!!:

The two skinny A/C tubes. One from an NA and one from a TT
They are different shapes. You'll need the TT one.
It has more bends to get around the Intercooler tubing.

The front A/C condensor is different, too. The TT is the
one on the right.

These A/C accumulators are completely different as well. The holes
for the tubing are on different sides and at different angles.

Here's the NA large diameter A/C tube and how it sits in the car up high
on the shock tower.

Here's the TT large diameter A/C tube. Totally different. Sits way
down on the shock-tower.

I think we all know this, but the NA radiator, on the left, is way
too big to allow the Intercooler tubing in. the TT on the right.

The upper clutch bleeder tubes on the passenger
fender are different as well. You'll need the TT one.
(not sure which is which--I think, the straighter one is TT
since it shows up in the pix below--duh)

Even with the proper clutch bleeder tube, my NA frame has this peice
that stuck out and conflicted with the tube. The TT frame was flat here.

A couple of well-placed hammer blows and problem solved :-)

The NA Power Steering tubing is very straight with few kinks.

The TT PS tube has more kinks to fit around the Intercoolers.
Doesn't seem important? see the pictures below of the Intercooler
Piping and how tight it all is.

If you care about the carbon canister, the 3 steel tubes
come around this corner like this, but will block
intercooler tubes. You will NOT be able to get the
Intercooler tubing in with the NA charcoal canister.

The TT canister 3 steel tubes are specially routed very tightly around
the corner to allow Intercooler tubing to fit.

A FREE RIDE, on my 1993 NA, the holes for the
I/C brackets were already drilled and tapped.
Some of these holes had rubber plugs in them to protect
the holes!!

Same here, already drilled and tapped. Intercooler brackets again.

I actually bothered to remove the I/C tubing brackets from the TT. I
welded
them into my NA frame. Then later, I sawed all the tubing support
brackets
off the tubing itself--so I could get the I/C tubing in and out the car
with the engine in.
So these, I don't use anymore.

The NA frame does not have the Oil Cooler bracket holes.

I drilled some holes and tapped them.

Real easy. Maybe 10 minutes later, I had the oil cooler bracket
attached.

OK, this is wierd. The 1993 TT donor car had both sets of oval holes to
mount the lower A/C condensor feet. A set for TT and a set for NA
condensor. I thought the NA would be the same.

WTF!!!! The NA only has NA condensor feet holes. I had to cut some
to fit the TT condensor.

Here it is after drilling two round holes real close together, and
using a
cut-off wheel to join them and make them an oval. And you can see I
have
welded the TT radiator brackets on as well. NA rad brackets are still
there.

For those of you how may not believe you need the A/C tubing, the Power
Steering
tubing, and charcoal canister from the twin turbo, her's the whole
driver's side mounted with I/C
tubing in place. You can see how tight everything is.

Here's the passenger side from above, looking down.. Oil cooler tubing
in copper--which as you
can see, needs the TT A/C tubing to get by.If the NA A/C tubing were
there, the oil cooler would
be clocked. TT I/C tubing in black. The new oval hole-cut for the
A/C condensor
The old NA and new TT radiator brackets in place.

The TT radiator, and the silver edge that the black bracket wants to
grab. But there's no hole.

Again, put it in place, mark the hole, and drill and tap.

If you're using a TT tranny, and have an NA rear end, you'll have to
swap out the speed sensor that is
mounted inside the side of the tranny. One is for NA and one for TT. I
can't remember which is which.
But when you pull it, get the other color, obviously.

It's obvious the red gear wheel is larger, but they way they fit either
one into the same tranny and have it meet
up with the same worm gear inside is pretty cool. Notice, the red one
is literally slightly to the right on the barrell.
(I know, the picture is pretty out of focus)
The hole for it is actually offset in the barrell and makes it meet up
on the gear in the tranny
the same way the blue one would.
