Hello
I'm thinking of turboing my xr3i. What do i have to do
whit the enginemanagement, injectors, etc to make it work?

 

you can go the frst route, then it's only a few little mods to the loom then, if you go megasquirt, then it's even simpler, just chop the wires on the ecu plug and use what you need from the inputs.

 

Do you know if there is a step by step guide how to convert to fiesta rst?

 

its not all as simple as that tho mate
u will need and oil return strenthened bottom end lsd brakes exhaust turbo the efi loom is easy u just unplug the old loom and add the new one it all unplugs easy job but its more the hardware things u need you would be better just buying a frs and dropping the engine in ur xr3 personally id go better and 2ltr zetec turbo it

Thanks

 

We don't have fiesta rst here in Norway so can't just buy one and drop in the engine. Have all the other bits from an escort rst so that is no problem..
