      Rix, you can't fit the RS2 injectors without a chip programmed for them. You'll soak the engine in gas and wash the oil off the cylinder bores if you use it a lot...

          Never heard of that mod, dont fit the injectors until its mapped for them. it will run badly. BTDT.

            it´s very easy to do,gives 5-8mm bigger trottlebody area,just take the 2 screws out and remove the lip/piece,put 2 new screws and 2 nut´s inplace of the old ones,give them some glue,and it will hold,mine has for a year.

              I brought my injector to a company that cleaned them ultrasoon. First they test them, if they are dirty they will clean them, and replace some parts. It costed me 120 euro's total. It really made a big difference for me, the car is runing a lot smoother in high revs but is also a lot more stable at idle.

              regards,

                i know some of the people that work at the lokal bosch,but i need the car every day so will soak them in ipa and see if it helps,idon´t want to use money one the std. injectors when i have brand new rs2 injectors laying at home waiting for me to save up for the last items/and adjusting.

                  I brought the injectors and could pick them up 4 hours later, It also doesnt take long to take them out and put them back in.

                  Put you are right that is a lot of money if you want to change them in the near future.
