58 mm turbo, .63 precision hot side 50lb injectors and matching TT chip. All items were on the car when purchased and am guessing that they are at least 15 yrs old cause the date is scribed on the injectors. I had this on a stock engine and it ran flawlessly. One draw back is the actuator I believe is bad. The waste gate hole has been opened up. Looking for $550 for the combo shipped to lower 48. PayPal only,buyer pays fees.
