Supercharger or Turbo

If its the car I’m thinking of I’ve worked on it before, it was purchased by a friend about a year ago with all the suspension parts already on it. Had AC/PS/ABS/heat delete already done, a wire tuck that causes some electrical problems, and some weight reductions. An owner a few back used to autocross it. Car initially blew oil smoke in vtec, head was rebuilt with KMS components, then it had other issues when it was put back together (dumps coolant into the cylinders once warmed up). Kid was in a tight situation, and had to sell it. OP bought it recently.
