Please let me know if possible then on what cost i can install it..? Also can i put china made plug wires if car is missing due to plug wires?
Yes you can. Will cost you 15-20kYou should buy brand new original wires rather then chinese cheap ones.
How much that will cost?
And what about HPS and the power steering belt?
I would advise against changing to EPS. The original is good enough.
No idea about HPS. I already shared the cost of EPS above.
