I dont know- but I DO know that they wont give me the 3L- as it didnt come stock in the car. I talked to Kinetics Racing (they make racing Duratec motors)- a worked 2.5 with about 300 hp N/A is around $9000. FYI they race cars had problems with the trannies- not the diffs- the tranies- the drivers would floor it on a straightaway and would rip the teath off the gears- EVERY TIME!!! not out of the corner- on a straight!!
