01. The Honda Fit's 109hp 1.5-liter engine is at best mediocre in terms of performance when put up against the K-series engines. Here's an image of the Fit motor next to a Jackson Racing Supercharged K motor.

02. In order for the swap to be fully functional, the transmission should be selected from a Civic Si or RSX when used with Hasport mounts. The '06 Civic Si transmission can also be mounted with the Hasport motor mount kit. To use an early Si or RSX transmission will require the use of the RSX shift mechanism and some modifications to make it fit under the Fit console.

03. Design and manufacturing for billet mounts is currently in production at Hasport. In the meantime, Hasport decided to build brackets to use with the stock mounts to allow a quick and easy installation of the K-series motor.

04. The Acura TSX, '06-07 Civic Si and Accord K-series engines will require an adapter plate to mount the snail style manifold. The adapter plate allows the use of a water bypass that is necessary for cooling. Also included on the manifold is an EGR port which Hasport conveniently blocked off.

05. This is an adapter plate that sandwiches in between the snail-style intake manifold and TSX, '06-07 Civic Si and Accord K-series heads. The aforementioned heads have a coolant passage built into their intake manifolds, but not on the snail manifold.

06. Here is the back side of the snail manifold and TSX manifold to show the water bypass and EGR ports.
