AX 1992-1994 telstar motor

[graham7773]

Was the AX Ford Telstar fitted with the 2.2 liter 12 valve sohc engine as well as the 2 liter dohc 16 valve engine. If they were, can a dohc engine be swapped out for the 2.2l 12v sohc resulting in a 10% increase in torque and/or 10% increase in kws. Assuming it can be done, is there much of a problem with wiring or computer? Too big a job?
