Re: 87 ford turbo coupe engine in a YJ?
Take a look at the torque curve of most turbo 4 bangers. All your power is made way up in the revs, not a good 4 wheeling motor, unless of course you are doing possible sand or mud drags. Toyota figured this out years ago, they put their turbo 4 as an option in their 4 wheel drives, I believe it lasted all of 1 yr.
