I have a 99 taurus engin (late modle 6/99) And I am going to be turbo charging. Is it recomended that I run with the heads from the taurus or the heads from the contour? Keep in mind I will be runing 14+ psi. Now I am asking because I want the compression to stay low to acomidate the turbo, but I remember that the contour heads would raise the compression to 11.25. So, do I leave it alone or do I do a head swap? Or do I go out and get a 2000+ Taurus or escape engin? Also, one more question. By replacing the piston rings with the clevite ones, will that solve their problem?
Thank you in advance
~Mike

all i can say is wow!  Might want to read up on this stuff. You should at least have some basic knowledge before undertaking a project like this. Adding the contour heads will bump up the compression like you said and will cause problems with high amounts of boost. I wouldnt even run any boost with that compression honestly. I would keep the 3.0L heads since they have the bigger valves as well. Next, clevite 77 makes bearings, not pistons rings. If you do decide to go wtih a set of custom pistons, rings will more than likely be supplied, or you can get some from Sealed Power.
PS. Forced induction questions belong in the forced induction branch.

14+ psi requres forged rods and pistons. if you dont do that your engine wont last at all

well, at a bare mininum it requires pistons. Nobody has tested the limits of the rods yet.

Okay, thats what I thought. Was not sure what the difrence in flow was. And I've got the forged and pistons covered. I blame my bad memory for my comment on the piston rings.

what about your tranny?
im not familiar with the taurus atx, but i dont see it holding up long (if at all) against a 3L running 14+ psi!
you might think about fitting in a mtx75 from a contour. it would be alot fo work, and probably costly (custom axles, mounts, etc) but it would hold up far better than teha tx (if you get a LSD) and be more fun, and faster!

Not that the MTX-75 would last any longer at all...
