RE: 99 GT v. 96 GT - mods
They would be about equal and both stink to bolt ons. The older car would have higher compression thus the extra 15HP you listed. Depending on the gas available the extra compression may require a weaker tune to prevent knock. Not on you list/question but if you are looking save for a Mach 1 or Cobra. mark

ORIGINAL: 06mustang88i think the 96 would because it would have a higher compression ratio than the stock 99

A full point of compression adds about 5% power. The difference in compression with the PI swap on the '96 would be about .5 so it would have 2.5% more power all things else being equal. That's about a 5.5 HP increase if that. Also I believe the -'96-'98's have a lower spark timing curve than the PI motors so it would lag there. It would really be a toss up depending on the rest of the motor and exhaust, etc. Mark
