Matt Powers just posted a photo on Facebook of a naked engine bay in his S14 saying “This thing ripped and served me well, but was starting to get in the way of victory!”

He continued in the comments by confirming he is keeping the chassis and ditching the engine. So what next? SR20DET? Or are they going to go extreme like the BenSopra 380SX that was just shown at TAS? VQ38 S14 drifting would be an interesting thing to see. Looks like we all will have to wait and find out.
Update 1-18-2013 – Later in the night Matt posted in the comments that he is going to just put in another LS but “a more built one” so it looks like any interesting combos is out of the idea for his s14.

Entering the 2012 season many were unsure of what Vaughn Gittin would be able to do, after winning the 2010 Formula D championship his 2011 follow up season ended with a lackluster 11th place. His first race in 2012 Vaughn showed up with his new Falken Tires & Monster Energy 2013 Ford RTR Mustang with some stunning livery and he looked like he was ready to take another run at the title. He qualified 3rd at round 1 but then amazingly gifted Odi Bakchis a win in his first match and fell out in the top 32. Vaughn Gittin Fans were not quite sure what to expect when he had a similar performance at Road Atlanta and was knocked out in the top 16. Round 3 was slightly better qualifying first, but falling out in the top 8th. But then come round 4 and 5 it seemed like the old JR was back with a new hunger taking back to back wins and putting him in the running for the championship. Vaughn placed 3rd in Vegas and was in 1st place in overall points entering Irwindale. It seemed like Vaughn had worked everything out in his RTR and wanted that 2nd Formula D Championship badly. Then in the top 8 after a pretty conservative run he unexpectedly spun out while chasing Patrick Mordaunt. All Vaughn could do was sit back and watch where he stood when all the smoke settled. In the end of 2012 Gittin finished in a very respectful 2nd place in overall points.
