My fiesta is a mk2 xr2 which is currently being converted to rwd and using a 1600cc zetec engine. Its using a type 9 sierra gearbox, escort mk2 back axle but converted to 5 link and to have coil overs. The bulkhead has been modifyed to take the zetec engine and a transmission tunnel has been fitted. It has escort mk2 inner wings and chassis rails. A mk1 fiesta dash. Four link body mountings were cut out of a friends group 4 escort after he stuffed it into a tree. A friend of mine knows alot about tuning engines and he recons he can get about 130bhp out of a 1600 zetec for not a lot of cash. Hes on about using an 1800 inlet cam and keeping the 1600 exhaust cam. Dont know why Im just going to do what he says. On the inlet side Im using an early 1800 mainfold and injectors, but the ecu, throttle body and engine loom are from an efi xr2i.The fuel pressure is also going to be raised.
