top speed should not be reached anywhere but on a track. its just not safe.
It does say which ECU they used, but thats not the point.
If i had another car with an auto trans, i would personally swap in a b16 trans on the h22.
The only limiting factor should be the cost. Doing a h22 swap with the h22 trans will more than likely be the cheapest alternative. Unless you just go out and buy a new auto F series trans.
