hi my criteria is - must be under 2070cc and N/A. not on an unlimited budget - will spend about a £1000 but may have to spend a lot more!

what engine is best - got to be either duratec, st170 engine (zetec) , or vauxhall 16v red top.
what do you think is the cheapest route to 200bhp and a good amount of torque? (going in a race car).
need to bear in mind cost of ignition/carbs and bellhousings/sumps.
- by the way its going in a mk2 escort.
