firstly, car is a a4 1.8t quattro sport 1999
has a ajl enigne, and its a shame it has a ko3 and not a ko3s
so am i right i saying the ko4-015 is a direct swap over to a k03?
ive decided for now a gt28r/s isnt going to be viable for me at the moment.
for which reasons do the other ko4's not fit?
as i have a tqs the fuel pump is good for 300bhp, but do i need injectors or are the stock ones good to?
fmic, decat and remap is a must, exhaust is 2.5 i believe so worth having a decat or leave stock cat?
i have searched but just nothing available to me that answers the question
