Sisco, it looks as if you are trying to stuff a M104 - HFM motor in your car. THat is fine if you decide to go w/ a custom fuel rail or independent throttle bodies. etc........... My recommendation is to use a M104.980/981 which is a I-6, 24vlv and is a CIS. I have seen this done b 4. Basically it is a drop in application. You have to swap the motor support brackets and put on brackets from a 190 2.6 (M103) and of course the items/changes that you had mentioned. What trans are you planning on using 16-vlv 5spd-Getrag or 300E - 5 spd manual? If need more specific just let me know and I can put you in contact w/ the guy who did this. If you go to the 190REV site and go to the gallery section and look @ "Mike's 190" you will see the mod already done. By the way whta year is your 190, b/c that will make a difference.
