Possible. Easy to do....cheap to do. Could rule it out. Have to identify problem first.....then confirm it. Then fix it. Is it lack of fuel....fire....or air.

Hard right turns at track speeds with no catch can means the car is probably inhaling oil. I can't believe you didn't observe the cloud behind you. Did you look behind you?

I did look behind. No smoke. Also, the turns I'd describe as spirited street driving. Kind of like taking a sharp sudden sweeping right while turning on to another traffic-less street at 2am. It's nothing a normal S driver wouldn't do to put that grin on your face. It's nothing drastic like at an autox or track. I'm stumped!

Kinda sounds like a fuel pickup issue. I remember my dirt bikes would do this when the fuel filter would get clogged. Hesitation on hard turns.

Good luck!

What are you bumping for? Seriously sounds like fuel starvation issues
Here's some threads to read through and see if it matches

I just wanted to report back and say I found the solution to my problem! It was something I totally did not expect. While leaving work the other day, there is a small bump in the road as I have to make a right to get on another street. Right after I made the turn, the car hesitated, stumbled, and eventually stalled and turned itself off. It was just as if I lost fuel pressure or had a bad MAP sensor. I coasted for a while and turned the car back on. It fired up as if nothing happened. I purposely made the block to make the same turn again making sure to hit the bump. Same thing happened once again. This made me 100% certain something was indeed loose under the hood despite me scouring every component I thought could cause this -- MAP, dirty throttle/IAC, dirty fuel filter, fuel pump, etc.

It ended up being that the passenger side TDC sensor bolt was missing. Despite me never having removed the sensor, the bolt somehow came out and the TDC sensor was moving as I turned right and hit bumps. I looked it up and naturally found someone with faulty a TDC and similar symptoms on S2ki. My s2k drives like new now!
