96 Duratec Swap - advice please
My parents have a 96 sable that has a 3.0 Duratec with a dropped #4 intake valve (broken spring). I am assuming it has done considerable damage due to fragments I found and the chewed up spark plug, therefore too expensive to repair. Please chime in if I am off on this.
My folks want me to look into a low budget engine swap as they prefer to keep the car (they invested in a tranny rebuild for it not too long ago).
I have done a lot of engine repair before but not a complete engine swap. While I am confident this is within my capability, I do have a few questions at this point and was hoping for some input...
- What years of duratec engines can I pick from? It does not appear from the reading I have done that there is a lot of differences in newer years but I don't want to have to do a bunch of wiring or major modifications for this swap. I'm in Nebraska, and so far my engine search on car-parts.com indicates this engine is more expensive locally. However, with the price of gas or adding shipping, it does not seem to make sense to expand my search too far.
- Is there a mileage limit that I should stay within on the donor (I was thinking < 125K). Also, comp #'s? It look like 190psi is good but a lot of vendors seem to give cold compression #'s. Is there a good way to convert this to a warm #?
- Depending on the year of motor, do I need to also get the ecm from the donor motor (more $)? If so, does the ecm and/or the keyfobs have to be reprogrammed?
- Is there anything in particular I should be aware of if I decided to go ahead with the swap? (Either checking, replacing, swapping, or firing up the donor motor)
Thank you for your replies.
