eBay turbo kits are a gamble. Some people have been runing them for a year or two without a problem. Other peoples kits shit the bed within a month.
The kit is not safe for a stock civic. To run it properly you would need some form of engine management wether it be a crappy fuel management unit(FMU), chipping your ecu and using software such as CROME, Neptune, or Uberdata, or spending big bucks for a licensed standalone unit like Greddy Emanage or AEM EMS.
