1.8s are brown too, so the same as 2.0l

mine was a converted 1.6 > 2.0l as well, all the cam sensors, crank sensors etc are the same, but quite rightly the MAF and TB is diff

think the 1.8 MAF is the same as a 2.0l however, but i could be wrong

tb size i quoted earlier was for 1.8/2.0l

not sure on 1.6 size, think it could be 45mm?
