I have a 97 'Tour Sport.
I don't really have alot in the way of performance mods;
I put an oil cooler on (keeps the oil around 180 degrees)
I got NGK TR6 plugs and gapped them at .40
I went with a 180 degree thermostat and water wetter
Ford Motor Sport 9MM plug wires
CTA intake
2.25" cat back exhaust w/ Dynomax muffler
And a custom Superechip program
I believe the custom program has helped alot.
I asked Zex what was required of a car to run a 75HP shot safely (like air/fuel ratio, timing retard, plug gap, fuel octane, etc.) and and then relayed that info on to Superchips along with a dyno plot of my car.
I checked the plugs are they are still shiny after 3 weeks and three Saturdays at the track.
I can run up to a 102HP shot with my custom program (so I have been told) but I am unsure if the engine internals will handle it.
I will probaly move up to a 85 or 90 HP shot.
Along with the larger HP shot, StreetFlight intake, ERam, and optomozed TB, I hope to be in the 13.8's or 13.9's.
Then I'll have to start thinking about a Quaife and new clutch.
