HOW TURBOCHARGE AN ENGINE WITHOUT EMISION EQUIPMENT, my engine is made to run with 95 leaded gas, the year after in my country change to a 95 unleaded gas an that what im running now, no egr,no o2sensor???

I plugged my EGR, and still had an 02 sensor

I dont think it really matters anyway. You can run a "leaded" type engine on unleaded fuel, just not the other way around because it will ruin your cat.
