    MC engine with RS2 IC?

    I have MC1 engine and i want to raise the presseure to 0,8-0,9 bar (0,4 in standard). I want to install the RS2 IC. What do You think about this setup? And the second question... Is wastegate S2 spring stiffer therefrom MC spring?

      I have a stock petrolpump. What is with this number? Is it a factory number of pump (044 ... ...)?

      Yes it's some problems with this ubgrade. RS2 IC is very big and it will take all place between lamps. And it will curtain the water radiator. One inlet of IC has to be turned. I have fears about cooling engine. I have now a MC2 one pass IC and it's 4 cm waider than the stock dual pass. But he has plastic ends.


      I have '88 Audi 100 Avant quattro with MC engine (one knock sensor) and Audi 200 20V look.

        i ment the fuelpump...... it have a borsch nr the last digit 044.... give 175liter at 7bar........you have to make another fastend in the petroltank,or use the org as a feedpump to a litle fueltank in the enginekompartment,then the 044 pump to feed the injektors,havent the P/N ..... use BIG tubes and only 1 silencer from the turbo,gives quick spool up and top end power....at least 3"...... and fix the alternatorreg,go for 14,6volt-14,9volt gives better ignition,and more power to the sparks....

          It's very interesting... Two petrol pump and second fuel tank... I think about it. What car has 044 pumps?
          Standard Voltage is 14,1-14,3. It's quite simple to do 14,6-14,9. Just replace the ori stabiliser with controllable. Piece of cake
          What about k-jetronic distributor? Will it suffice? Will only effective pump suffice? How do to bear good AFR level? Ehh...I want to EFI or something...

                Unfortunately IC from Audi RS2 is for large. Problems are right away. It IC will be custom about twice greater from serial and whole aluminium.
