i have a AAZ 1.9L in my 89 jetta flair and i want to do the gov mod. the gov cover on my pump is far more complex than a 1.6 td pump. so can i put a 1.6 TD cover on my 1.9 pump to make life easier. the pumps are so close to the same that it should work i think. i have do some mods all ready boost controller 26 psi, gtd nozzles, soon 2.5 inch exhaust from turbo back. it g teched at 96 horse and 147 torque a nice gain thus far. still give wicked milage 650km on 40$, at 1.09 a liter.
