i just got done putting a 1.9 from a 97-98 canadian jetta (i thought that they were tdis by then?) into a mk2 coupe. the original turbo was shot so i put a t3 on it. it seems to go pretty well with the best part being the tranny, 65 mph in third... ive modded a few 1.6s with gov mod, more fuel, more boost, intercooler etc. anything special about the 1.9 that i should know about or just basically tune it like a 1.6?
