i've seen 4cyl engine rated to 44hp, mine should do 70hp, all the way- i think- to 170hp;can i use an injection pump from diff model and use it w/my engine -either changing things or not- or it can not be done..i assmue different fuel amount for different engine, but maybe the fuel delivery can be changed...

also, can i take a non-turbo engine, and put a turbo in it--non turbo have less hp, so i can increase the hp?
