OK team, here we go.
22R-E into ST141 is a harder conversion than most would think. You basically need an entire RT142 to strip and transfer over. Brake lines fouling on inlets means you have to change the master, which has different outlets, which means you have to change the lines, which means the bias block doesn't line up with the existing lines, fuel hardlines are different, so you have to change them, and your fuel pump... wah wah wah wah wah.
3S would almost be easier.
