not even close. the SE ecu controlls the fuel injection and since the SE wasn't offered with an auto trans, it would have nothing for it.

Why would you even ask a question like that? You can get a fuel only Microtech to run a 12AT for about $500 bucks.

Well, the answer is going to be 'no', because the stock N304 ECU for the SE is designed to run 2x680cc injectors under normally aspirated (atmospheric) conditions, not boosted.

As soon as you boost your engine intake pressure above atmospheric, you're going to need custom mapping to keep up with the air going in. This usually requires some kind of ancillary controller that can be mapped, adjusted, and tuned on a dyno for best performance.

The N304 ECU relies on a lot of input signals to get good performance for 13b non-turbo applications, and running a turbo would quickly overpower the stock AFM, you'd be running lean, and your engine would pop like popcorn on a Friday night.

Sorry,
