It looks like your car needs to be properly tuned. It sounds like a combination of your timing and your fuel being way off, possibly your injector correction input and MAF is not working properly either. Not sure what EMS or Injectors you are running I don't have enough time to track this thread all the way back but this would be the issue I am leaning towards. If you are running larger injectors I suggest using a PFC, Tomei, Haltech or AEM unit for tuning. If you require base map for tuning I can help you out on this as well
If your intake pipe off the front of the turbo is obstructed or not working properly this could cause an issue as well. I would check into this and make sure it is not collapsing on itself or it is sealed up tight against your maf so Air is not getting into the motor after the MAF location.

It's stock everything, that's why I didn't suggest anything in regard to the tune.
Again, If the car ran perfectly before, and if the harness was changed for s14, and nothing else...(and the knock sensor delete)...then the troubleshooting issue is really 'to easy' and in either of the above. I'd focus less on the hardware and more on the few changes that were made. Even though the Knock Sensor is a oddball item, I'd never 'remove it'just for the hell of it.
