What all is needed to swap the instrument cluster from an 88 GT into my 93 2.3. I am about half way through my 4 to 8 cyl conversion

No, I haven't touched anything for the 5.0 swap under or in the dash yet. Would it be easier to just get a 90-93 cluster......crap now that I think about it the cluster will not work because in the 88 its flat and mine is rounded.....hmmm would a 90-93 be a direct go? someone said the speedo will read twice as fast if i leave the 4 banger cluster in there.

Grrrr, everyone has a pre 90 and swiches to a 90-93 cluster or even swap but noone swaps from a 90-93 to an 87-89. Could I just swap in a 90-93 5.0 cluster? Or would the computer read it wrong? What about swapping out the C250 and C251 from the 88 onto the 93?

The tach wont read twice as fast. It will read norm because you swapped all your V8 engine harnesses and what not. it will read just fine. I am pretty sure it is plug and play . the only thing I can think of that might not work is the gas idiot light that comes on when you are low on gas. I think that stopped in 89-90. So if you have that now you wont anymore. It is hard to say because supposedly the wiring harnesses are different under dash (so I was told). Good luck man. My car is an ex 89 GT power train in a 88 4 cyl body. So i know that work that goes into that. But I loved it an it only took me a few days.

Can't you calibrate the speedometer? I'm sure that's the least of the worries? If it's plugs in and works; then you can calibrate the speedometer from what I've heard.
