KLZE Motor swap in my 2002 626
 

I have a 2002 626 my friend also mechanic found a klze with bad valve spring from a customer and bought it for $50. We already swapped out the intake and my car runs better but I want to do whole swap only problem the klze has a distributor and my car does not. Has anyone done a swap like this? I don't want to rewire whole car and don't want to go with distributor. Also I heard I have to get computer re-flashed is that true and where can I find the company to do it? Any help would be great before we tear my car apart.
