sorry just seen what car you got.

best mod you can do to that escort is drop in a 2l silvertop from a mondeo. you'll need the modeo ecu of a specific code and swap over oil pickup, sump, flywheel and i think water pump and switch a pins round on the ecu plug. guaranteed 130 bhp and will have more torque than the 130bhp 1.8. pluss its a better base to start going for bigger power.

get yourself onto feoc-uk.com, loads of people on there who have done this conversion and swear by it. theres a guide on there too or a link to one.

edit to say: with a decent exhaust system coupled to a 4-1 or 4-2-1 it'll be 145-150bhp
