No, you can go faster. The needle just bounces off the trip reset button.
Late 1989 clusters did get a 140MPH speedo.
There are a lot of differences besides speedo between the 87-89 and 90=93 cluster. For the most part, they are physically different. The 90 cluster was revised to clear the airbag column, so it's bottom is slightly curved.
Warning lights are different as well between the two such as the addition of an airbag light in 1990 and the deletion of the 87-89 GT cluster warning pod., and as a result, they are wired differently. They cannot be swapped without rewiring the harnesses.
All 90-93 V8 clusters have a 140MPH speedo while 90-93 4-bangers got the 85MPH speedo
All 87-89 clusters got the 85MPH speedo EXCEPT fpr late 1989's which is when the change to 140mph speedos started.
will i be able to take the speedo out of my 93 cluster and put it into my 88's cluster with no problem???

Speedo will swap no problem as long as you unbolt the speedo mechanism from the clear plastic frame and swap it over.
Transferring the gauge face is another story. Just take your time, or just buy some overlays for an 89 w/140MPH speedo
Ryan,
You can do like Mike said and swap the mechanism over and the stick on face. The reason is because the plastic backing the face sticks to is different between the 87-89 and 90-93 speedos. Mike posted some pics of it earlier on here I believe.
Or you can cut, file and drill the 90-93 speedo plastic backing and make it fit the 87-89 cluster. That is what I did since I didn't want white faces and didn't want to mess up the 140 stick on face. You have to cut one of the locating tabs, drill out another hole for a locating pin, file down the housing a bit, and test fit the speedo in the housing several times. It took me like 15-20 min or so to get it fitting nice.
Here ya go. Keep in mind, this is my 1988 speedo bolted to the 90-93 plastic frame with the stock 1988 speedo gauge face trimmed to fit it. Notice how i reset the miles to 0
To remove the speedo from the plastic frame, just unbolt the two screws located at 3 and 9 o'clock on the reverse. Gotta take the needle off first though.

You'd either need to take your OEM speedo out and send it somewhere to be recalibrated, or get a 140MPH speedo from a late 89 -1993 car and swap it in like i outlined above.
Brothers performance and Late model restoration both sell white faced kits where you send them your old speedo (or an 85MPH speedo off ebay) and they will recalibrate it for you.
