Right now i have the stock dx motor but i went and pulled the si manifold and resistor box from the junkyard. does it make sense to convert to mpfi, do all that wiring, have that manifold on my engine if im just going to swap the motor anyway? wouldnt i just want to wait and put the new manifold on the z6 when i get it? and in that case, will i need a different ecu? because i was told for the dx i would need a pm6.

basically my question is whats easier, wire my engine for mpfi and change to a pm6 or just wait until i do my swap?

Feel free to add any other info i might need
