HI

Does anyone know what the difference is between a 105HP and a 90HP Escort XR3i.
I know that the 90HP model has a catalyst and the KE-jetronic. BUT what about the rest off the engine, is this the same as the 105HP model.
Is all this a simple matter off chopping off the catalyst and i have a 105 HP engine.

Sorry for any typos, but are living in denmark and havenīt used english in writing in 15 years
