thanks for the input I really appreciate it! I'm going to just use the 3.0 it would be the simplest way to go about fixing it. I will also pull the M111 & transmission out of the c220 and save it for later because its going to be a ton of work to get it all working correctly all the extra wiring! yikes

The only thing I am worried about is it going to pass smog with that larger engine? its only .4L larger which isn't much and if everything is working correctly I assume it will run within the limits. it would be so disappointing to do all this work for nothing
