I bought a jaguar engine they ship the engine after 16 days, when the engine arrived there were no turbines and other parts. the company writes:
If you are not willing to change the feedback, I have no reason to then give a good will gesture. If you would like to continue and get a partial refund on the engine, you would need to let me know if you are willing to change the feedback.
They request change a feedback before refund and I don't have the turbochargers, the pipes and the money for 20 days of delay.
trust these people.....
