right guys i need ya help.

i want to build myself a zetec turbo engine, i can do the mechanical parts fine but i need help deciding what parts i need to get the power that i want


im aiming for 250bhp from a 2.0l zetec engine, using a decomp plate (iv weighed up the pros n cons but price got the better of me)

what compression ratio do i need to be aiming for

what injectors do i need

what turbo should i use (got a stage 3, t3 turbo ready to use)

what boost should i be able to run

management? will fiesta rst be sufficient enough



thanks
