1995 Pontiac Firebird Trans Am LT1 Instrument Cluster - V8 - Auto 5.7 - 155 MPH
Thanks
Sara Lou
but there will need to be some calibration changes made because of the switch of speedometers
Is yours broke or something?
Sara Lou
its basically changes that are scaling on the increments because yours covers the same amount of space with larger increments where as the other one will cover 155 mph in the same space
It will fit right in... no mods or calibration needed, but your speed limiter will be kept and still kick in at the same speed, which if I am not mistaken comes in 108-110 mph... Back then when our cars were new, cars NOT ordered with Z-rated tires came with the 110 speedometer and with a speed limiter set at 108-110 mph. But that cluster would work.
Hope that helps....

transam5.7 is right. not all f-bodys came with Z rated tires. thats y they have the 110 speedo. as far as tuning i could have sworn you needed to get the pcm reprogrammed for it to be accurate, but i personally have never done the swap so i dont know for sure.
Thanks TransAm thats what I thought. I know about the speed limiter, I hit it traveling to work one morning!!!
The reason I want the gauge is because I just got a laptop and one of the first things I will be doing is removing the limiter!.
I wasn't sure about the 4th gens, I know the 3rd gens are interchangable, i'm in the process of changing out the 85mph gauge in my '87 Camaro for a 145 mph.

And I thought all the V8s came with Z-Rated, thus the 155mph speedo?

Yea they are right some came with a 110 mph speedo.
I saw a Camaro z-28 once with a 110 speedo and I was like WTH?
But it did have 16 in. cheapo Goodyears, not Z rated. and if I remember correctly it was an A4

And all this time I had no idea I was driving a V6, amazing a little V6 can spank Mustang GT's too!.

Get a 155mph speedometer from a 94-95, and it fits right in without any modifications. You'll still be bouncing off the stock speed limiter.
