helo ppl
firstly i would like to say i dont no a great deal about mechanics

what i have is a mk3 escort with a cvh 1.6 injection i am after more power but someone mentioned to me to put a zetec bottom end in it but after further talks i have been told this is not best option
and some one said put a rs turbo in

i think rs turbo is probaly best i have around £600 to spend on getting it done but not 100% sure what parts i would need to achive this
would a fiesta efi turbo go in to mk3 and would i need to change hole loom
and would i get everything i need to finish for £600
advice welcome just need little more power and list of what i would need to achive it
thanx
