One of the many problems with fixing ITB. Did the car come with the 102 and the 83 in teh states? are the same motor sans compression? what CR is the what?

Run through the process it would result in a big difference.

102 hp= 102*1.25*17 = 2170
83 hp = 83*1.25*17 = 1765

car factory weighed right aroudn 2k lbs.. not sure if the lower number can be achieved.
