98 Chevy 6.5 turbo blew found a 94 gmc 6.5 turbo wondering if its all the same or if I have some improvising to do with wiring and or computer

 

94 motor is OBD 1
98 is OBD 2
Swap things the other direction-make the 94 like the 98 was.
Also check the # on the 94 IP-if it ends in 5068, you are going to have to swap the 98 IP too.

Take everything from the 98 an put it on the 94 block. Electronics, ecu, etc...
To bad you didn't take the simply route an find a 12 valve and a nv4500 trans and transfercase to swap into it.

 

yeah that would be good but I don't have a lot of time to do this motor swap unfortunaly thanks for the reply I will defiantly be changing all that then thanks

 

like he said, keep everything that is 98.
