its not that bad of a job on those,i did have to switch the ecm out though because after doing all this i couldn't get the car to start,after swapping that out the car fired up and ran real rough and the smoothed out,you need a manual on both engines though to do this,but it wasn't worth the trouble to do this,i had two cars to work off of though when i was doing this,so parts wasn't a problem,good luck.
