Escort turbo and Fiesta turbo engines are identical however the FRST block has a hole for the crank position sensor - although later escort engines also had these.
The LSD is in the gearbox and not the clutch...the clutches are the same (unless talking about S1 and S2 turbo in which case the S1 has a 200mm clutch while the S2 and FRST have 220mm clutches)
the inlet manfiold and fuel rail are different and the FRST uses a coil pack instead of d/cap IIRC
what power are you after?

The difference that bassboy described are due to the fact the FRST is EFi rather than the ERST's MFi.

Jonezy :erst uses a bosch ecu
frst uses fords ofab ecu
Half right
ERST uses the older mechanical fuel injection from Bosch in the form of a revised KE Jetronic from the S1.
whereas the FRST uses the EEC-IV ECU from Ford. It came in two versions, OFAB and OFAC fitted to later cars.
OFAB is older but prefered as it can run higher boost more easily whereas OFAC has more safety feaures such as causing LOS if the ACT's go to high.

yes mate you will need uprated pump and injectors
standard head and cam
you could low comp it slightly
GRS/Pro alloy/cosworth intercooler
ally rad
stage 2 t3
will EASILY see 200hp...just make sure you get the BIGGEST intercooler and suitable injectors and get it live mapped

if i were you i would send it in to Motorsport developments in Blackpool mate for the live map
as for rolling roads...just pop along to a local RR day...but try to go to one with a Dynamics Duo RR i think they are called as they are the most accuarte apparently
200hp is easy out of these engines

a live map is set up for your car specifically not your engine spec as off the shelf chips are.

Phillie*Nic :cheers mate will do. roughly how much is a live map? and what does it do haha
a live map is basically programming the ECU to provide the CORRECT air to fuel mixture for YOUR engine...
EVERY engine in the world consumes air differently despite engines being spec'd the same....it all comes down to a HUGE number of different things - fuel delivery, air filters, exhausts, wear and tear on components etc...
now imagine an "off the shelf chip"...this would have been done to suit ONE engine that was probably in its prime and in good condition etc etc...now put that chip into an older engine, or one with a different exhaust, or air filter etc and the fuelling needs altering SLIGHTLY again right? YEP!
so say you upgrade to the next bigger chip....now this chip suits say 200hp...but say you only achieve 180hp...why is that?...say you use the CORRECT components for achieve 200hp...namely a HUGE intercooler, nice turbo, but retained standard head and cam...it could be that the "200hp off the shelf chip" was designed for an engine running a particular exhaust/air filter/head modifcations etc...the 200hp chip COULD be overfuelling your car like mad! or even under fuelling the car! could also be setting the timing advancement wrong for the application and causing the car to pink!
so for any given modifications, a CUSTOM remap needs to be written for the ECU to supply the correct amount of fuel and for the correct duration...
as a live map will get the most out of your engine as its written for YOUR engine, you will be getting the most power and reliability for the given modifications ....
a live map also entails having the car driven on the road under all conditions to check that the fuelling is correct over all loads and in REAL LIFE situations....and not on a RR where the loads are simulated and cooling is not as efficient as it is on a real road.
we cannot control the amount of air that enters an engine...but can control the amount of fuel to burn with that air for most power/fuel economy etc etc which is what a remap does for YOUR engine and YOUR engine ONLY
hope this helps

if there is enough paint layers on the car...it is possible to just cut the paint all over (professional job/bodyshop only) and polish it back up...will get rid of all surface scratches and look like new for about £80-100
