Turbo Tachometer factory look of Fiero dash

Let see if I can figure out how to wire this in my Fiero dash so I can see how much boost my Supercharger is putting out. This was the closest Tachometer with a boast gauge as I could find to make it look stock. It's out of a 1993 Pontiac Sunbird turbo car, Pretty hard to find these around anymore.

In the first photo below shows from left to right the stock Fiero Tachometer then the Sunbird turbo Tachometer then a turbo Tachometer out of a GMC Syclone. I chose to use the Sunbird one since it to me matches the stock Fiero one the closest.
This photo belwb shows the 1993 Sunbird cluster I got the tachometer I will be using.
Below is the Fiero Dash I'll be using.

This photo below shows the 1993 Pontiac Sunbird Tachometer and the 1991 Gmc Syclone Tachometer.
Below is the finished product, Not to shabby.

I decided the best way to connect the Sunbird tach to the Fiero's wiring was  to soldier one end of each of the three wires to the Fiero dashboard clips. The other end I used the ring terminals pictured below to attach to the back of the Sunbird Turbo Tachometer.



 Below marked in black marker is two ares I had to cut down 4.6mm to make the tachometer fit properly I'm the fierF housing.

These next couple of photos were some I found online that I used.

Coil pack mounting.

Image
Got my Coil packs today. I used a coil mount from a non Supercharged 2000 Pontiac Grand Prix GT 3800 this works perfectly to mount the coils close to the left trunk side of the Fiero and will allow me to use stock 3800 length spark plug wires which I have chosen to use the zzp 10.5 wires. I did have to buy some longer 10/32 x 1 1/2 mounting screws to attach the coils to the brackets as my stock Ines were not long enough.

Found my Donor engine and transmission

Image
I searched high and low to find a low Mile 3800 Supercharged engine and transmission for my swap. I finally found one in Houston Texas. Cost me a bit more than I would have liked but it was one of the only ones I could find with low miles at just over 50k miles. It was in a 2004 Pontiac Grand Prix GTP.  At the time I did not get very good information as to what all was needed for the swap other than engine trans wiring harness computer and axles. Now I know better that I didn't need the wiring and computer from that car since it is a drive by wire in 04 and my Fiero is drive by cable so in order to make it work in my Fiero I need a 1997-2003 wiring harness and pcm. Would have been nice to know this before I bought the wrong stuff. Hopefully I can sell the 04 wiring harness and pcm and get some of my money back.
