the 89 up NA is a common block, only the early 2.5 88 and old was tall deck. The later NA engine just needs the rods, pistons and a hole cut for the return line.The n/a 2.5 was a tall deck motor with a different length rod. You could make a 2.5 tall deck setup into turbo as long as you have the right length and strength rods and pistons to make the right compression ratio.
but just making a 2.5 n/a tall deck into a turbo by just bolting on a turbo setup isn't the best idea.
:bang headwell i work at a junkyard and we had a spirit rt there with the 2.5 turbo that needed the engine and we decided to try a low mileage plain jane 2.5 and put the turbo, etc on it and it ran well and pulled great going up the road till we hit 3rd gear and it blew the rods right through the block like nothing. thats when we came to find out that the turbo engines have a heavier crank and rods and pistons and the pistons are dished to lower compression ratio. we ended up having to find a turbo engine at the end of it.
