Subtle, cute and economical are just a few of the words that come to mind when describing the new Honda Fit. If the "Fit is GO! " as Honda's catchy slogan suggests, perhaps Honda engineers should have considered shoehorning an engine more horsepower worthy of the H-badge, rather than a 1496cc engine that delivers a measly 109 hp. Long before the Fit was delivered to the U.S., countries in both Asia and Europe were already well acquainted with the Fit/Jazz as performance products began to trickle into the market. Fit fanatics began spending hundreds of dollars on aftermarket components, in hopes of doubling their horsepower. But, unfortunately for many, the gains of 5 to 10hp weren't what they expected from their Fit.
Hasport Performance, located in Phoenix, Ariz., has taken the Honda Fit to a new level. Although the K20 and K24 Honda motors have long been rumored to fit within the Honda Fit's engine bay since its debut, few have had any success. Hasport is one of the few companies to carefully analyze and perfect the K-series installation for the Fit, while creating an easy-to-install engine swap kit for any savvy customer to tackle on their own.
Forum chat rooms and performance shops have been abuzz recently with rumors that the engine height and hood clearance were major setbacks when dropping in a K-motor. In hopes of putting these rumors to rest, we asked Hasport marketing and product development guru Brian Gillespie on what is truly fact and what is fiction. "The engine bay in the Fit is tall due to the configuration of the Fit engine. While there seems to be a debate on what works and what doesn't, both the K20 and K24 engines will fit and engine height is not a factor. The intake manifold has to be the snail style manifold found on the RSX type S, 2002-2005 Civic Si and JDM ITR and CTR up to 2005. The snail manifold is more compact and is the only one that will clear the Fit radiator." Upon further research, we found out that the 2006 Civic Si intake manifold will cause clearance problems due to its larger plenum and less tapered intake runner setup. Gillespie continues by saying "The shape of the rack and transmission case also dictated the height the engine was mounted. As it turns out, the bottom of the engine wound up being the same height as the front suspension cross member. Side-to-side placement was also a no brainer. The K-series engine is as wide as the Fit engine bay. In order to keep the K-motor from rubbing, we moved the engine a little towards the driver side and notched the frame rail for clearance."
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. |
