well if you are looking at engine/tranny/computer all in a complete package which you may need you should shop around..... depending on the motor and the model you can see a used h22 complete for anywhere from 2300$ and up..... I dont know anyone who did an f22 to h22 but I think if the motors are the same size 2.2 then it shouldnt be THAT much of a problem if not any..... your car is made for an h22 so its not like cramming it into a civic or integra..... the h22 comes in a couple variations..... there is the plain h22 which is japanese and it is 220HP and 160 ft;ibs of torque, the h22a4 is an american h22 which is 200HP and around 150 ft;ibs of torque...... then there are other models of the engine which are more expensive (european h22) so depending on which one you want there will definitely be a difference in price and power so look them up a little bit on the web, I dont see it being much of a problem as far as putting the motor in.
