Yes it is a factory built engine from the usa, there is a data plate on it it is still boxed new unused the plate has a signature on it as well. comes with everything down to charge cooler pump header tank everything. They are also going to remap the ecu. work starts friday eve after work. I will have to run it in for a while but i will be sure to put it on a r/road soon after. Just see whee we are. I used to have a e55 so it has alot to live up to. But less than half the price so real good value. I also think these cars wil be classics real soon, How many are left out of the 883?? Do you guys ever meet up if so where is the next.
