I need a 145MPH to 165MPH Speedometer or a Speedometer that goes over 85MPH.

The car I will be putting it in is a black 1982 Firebird Trans Am, 305CI H.O.

and im looking for one that is cheap nothing over $100.00 please.


- Thanks Nic -

 

Did GM ever make a mechanical speedo for a TA that went over 85?

From what I understand they do but they are way overpriced....

 

You might double check your info. The 145's, for example, didn't appear in Camaros until 86, IIRC.

Years ago; I saw a cable driven Firebird speedo that read 160MPH or something like that. The guy told me it was a GM part - but not factory installed. Kind of like the 145 "Z28" speedo for the 82-84 Camaro.

I've got a 84 TA cluster showing 140,............... But it's METRIC and the readout is in KPH !! ( from a canadian car ).

Sorry I don't have what you need - just adding my !

 

i got a 140 set up from an 89

 

Factory 140 MPH Speedometer GM Part Number 25053568




Corvette Clinic 160 MPH Speedometer

 

do a search on ebay a speedo company makes em less then a hundo, also heard camaro units were mechanical until late 80's and bolt right in may need a needle change

 

Just an FYI: Camaro speedos were mechanical from 82-89. The speedo head is a direct swap. No need to touch the needle.

not true, some speedos had white needles some orange.... thus a change to match yours may be necessary

 

I see. While that may be true, messing with the needles is a design for disaster: plastic, fragile, breakable. And, of course, even if you're successful, you'll have to fiddle with the needle again to get the head to read correctly. Possible to do, yes; recommended, no. If you swap in the entire cluster, there'd be no need anyway.

I have an extra 145 mph gage cluster laying around it's in good shape just collecting dust in the garage

 

Simo, do you think that speedo is a direct fit for an 85 TA with TPI?

 

It would be a direct fit for either of them but the 85 gauges have the crossing pattern on the gauge faces rather then the plain black surface. You can contact http://www.autoinstruments.com

They have this for the 1983.



They may be able to do a 1985 as well.

There is also http://www.speedometerplus.com/

Good luck.

 

Where would I get a metric speedo for my 88 GTA? Our speed limits are all in KPH here.
