[84LX89GT]

Me and my friend raced up a hill going to another friends house and at the time i had a '91 and he had an '89 mustang, both 2.3L's. My car pulled on him fairly well but it was like watching two slugs race. It was horrible . That engine only made 105 horsepower or something like that to his 88 (i believe) and it got horrible gas mileage (close to 20). I much would have rather had his engine because my dual coil system had lots of problems. Driving either of the two you don't notice much difference in the torque band, but the dual plug engine has more top end (if you can call 4,000rpm topend).

Putting the dual plug engine in your '88 is probably more trouble than it's worth....but you gotta do what you gotta do i guess.
