no very much doubt it would be worth the hassle, plus the ecu plug maybe differant, and would there be a map sensor plug etc

The correct loom is easy enough to get hold of

a map sensor is a presure sensor that reads the presure of the inlet manifold and relays information back to the ecu

yes but you ecu will not be up to the job of fueling any think over a 1.3 let alone a turbo!!

if you want a turbo ka just fit the compleat engine and loom from a fiesta rs turbo it will bolt up to your gearbox and as standard will give you an easy 130hp

coolant temp sensor and crank position sensor.

You really don't want to be showing a 1.3 a turbo mate... poor little thing would get all upset and start throwing rods at you.

Best to go with what has already been done, 1.6 rst engine cheap and easy. With the hole fiesta wiring loom. I suspect the exhaust manifold would have to be custom made for the little endura as well and for the price of a manifold you have bought a running engine.

Rob,

hi rob,

the engine is on its way out anyway as its using oil, and im gonna be building another 1300 with slightly more ponies to go back in so if it does have a strop and throw its rods at me im not to bothered.

i kno the best thing to do would be frst engine but thats boring.

im going to make the manifold myself as i am rather nifty with a machinery workshop and fabrication epuipment to play with.
