what exactly do i need to convert from dpi to mpi?? i know the basics,manifold,wire harness.Do i need an si ecu? and how do i splice in the harness??
 
DON'T FORGET to get extra pins for those damn ecu connectors (for the wires you have to add for the dizzy i think?)! Also, IDK if most people just leave it off or soemthing but the Intake mani support bracket is a complete whore to put back on. I had a guy tell me you have to put a jack under the oil pan or something but i said F that and left it hanging there. Hmm what else... I used a 2 1/4" nail to pop the pins on the bigger connectors and a 1/32 or 1/16 drill bit for the smaller ones. Once you learn how to do it its easy. One of the connectors requires you to remove these retainer thingys first. Also keep track of which connector goes to your IAT, EACV and TPS (this messed me up at first lol).
Best of luck man, I wanted to kill someone at 2:30 in the morning when I first failed the swap due to those weak ass instructions. I wish I could remember all the other stuff they neglect to mention in there.

the dpfi mani bracket wont fit the mpfi intake anyways..on my first hatch i unbolted it from the mani and left it attatched on the block to hold my wiring harness in place
