We finally got the Civic hatchback with a K20z1 with a stock bottom and bolt ons retuned!
The dyno tuning session was at LawrenceBuilt Shop.
The bottom end is completely stock, but the head was freshened up with rocket motorsport cams, plus injector dynamics and real street performance parts.
This K20z1 became an animal on M5 Fuel.
