no it not a turbo. Just the stock is restictive. My plans are Cold Air Intake. and full exhaust; Header high flow cat and muffler. I just want one that is deep and and sounds good but not so loud i get messed with. I had a 94 B16 Hatch with header, deleted cat and put a $40 no name ebay muffler on it and I got 2 tickets cause it was too loud. I noticed a nice power gain but just too loud.
