The race was to be hosted at the state's fairground and was known as the Nissan World Challenge of Tampa. It was also the wet season, with rain alternating with dry sessions. The practice sessions were filled with some off courses which made some pit crews work harder than ever. Jay Cochran in his Spice SE90P Chevrolet, Firmin Velez in a Spice SE90P Buick, and Wayne Taylor's Spice SE89P Chevrolet clipped the wall after Tom Hessert spun in front of him. Chip Robinson's Nissan NPT90 would knock Martino Finotto's Spice SE90P Ferrari. Many Lights cars were hit by GTP cars, and it raised ire from chief steward Marty Kaufman. When things settled, practice could resume and Chip Robinson would set the fastest time with 1m05s573. Geoff Brabham was second with 1m05s681. Juan Fangio II was third in his Eagle Toyota, followed by Davy Jones in his Jaguar XJR10. James Weaver took 6th on the grid while Firmin Velez was the fastest Lights qualifyer in his Spice Buick. The race should be run under wet conditions.

Most of the cars had elected to run on slicks. At the start, Davy Jones stuck his Jaguar XJR10 between the two Nissan NPT90s. The First caution occured fast, and Davy Jones would take the lead, while Chip Robinson, Geoff Brabham and James Weaver pitted for new tires. Jay Cochran was out when he stalled his Spice SE90P Chevrolet. He had hit Scott Sharp's Spice and was hit by another car. When the racing resumed, it was Davy Jones, followed by Juan Fangio II Eagle Toyota, John Nielsen Jaguar XJR10, Wayne Taylor Spice SE89P Chevrolet, John Paul Jr Nissan ZX Tc GTP, and Geoff Brabham, Chip Robinson and James Weaver. Davy Jones would lead until lap 46, when the ADA Ford driven by Pierre Chauvet hit the wall. Another caution was set. The three leaders would pit simultaneously. John Nielsen Jaguar XJR10 took the lead, only to lose it when the field returned to green. The two Nissan NPT90s were back in the lead when John Nielsen pitted for fuel. Chip Robinson would pit the first for his second refueling session, in order to take on less fuel. He resumed in 6th, behind John Paul Jr, and this losing ground on the leaders. Davy Jones lost then two laps in the pits when he lost his rear wing. He would retire later from exhaustion. Geoff Brabham, still in the lead, pitted then, followed by James Weaver. Juan Fangio II was now leading. He would be caught by Geoff Brabham within 10 laps.

When the race reached the 100 lap mark, suddenly rain came into play. Geoff Brabham would pass Juan Fangio II at the chicane. James Weaver was still in 3rd place, 14 seconds behind. Chip Robinson and John Paul Jr were half a minute in arrear. Then Geoff Brabham suddenly lost control and skidded into the wall. Juan Fangio II was back in the lead, followed by James Weaver. He would elect not to stop in the first place, while James Weaver did it. Then the Eagle Toyota litterally floated into the wall, while Juan Fangio II was running very slowly. James Weaver would take the lead, while Geoff Brabham would slide at turn eight. He stopped for rain tires. John Nielsen had passed John Paul Jr, but he also spun at turn eight. He lost his rear wing and ended the race without it. The race was becoming too wet, and chief steward Marty Kaufman sent out the safety car. The chequered flag was displayed at the 110 laps mark. James Weaver gave the victory to Porsche for the First time in 1990.

The Lights class would be a battle between Firmin Velez-Tomas Lopez Spice SE90P Buick and the Spice SE89P Ferrari driven by Ruggero Melgrati-Martino Finotto. Firmin Velez would pull ahead of everybody right from the start. He would manage to lap the entire Lights field! Martino Finotto, in second place, gave the wheel to Ruggero Melgrati at the one third mark. At the two third mark, it was Firmin Velez to pit and Tomas Lopez got under the wheel. The two of them were still one lap behind the Buick powered car. When the rain came, Tomas Lopez went off course while Ruggero Melgrati went in and switched for rain tires. The former went off course a second Time, and damaged the nose of his car. Repairs cost him a couple of laps, and the Spice SE89P Ferrari took the lead, and the class win. The Essex Kudzu DG1 Buick lost a lot of Time in the pits, with overheating problems.
