welcome Juan..

a turbo kit on an 1.8 stilo is tiny bit more difficult aplication than on an 1.6 because of the variable timing..in ur case a G T25 is small and u ' ll need T28 ball bearing....

unfortunatelly u can not use the perallel ecu that we have cause is for 1.6 only and there is no 1.8 turbo yet in greece..so in order to make an ECU u need to find a programer in ur country that can progman it "on the road"...

it reeds from the throtle body, map sensor, lamba sensor.....
