Nestled in a plain-looking, clone-like business park in the heart of San Marcos, Calif. sits the Sportcar Motion (SCM) garage. Here countless Honda K-series engine swaps have been performed, including those in the chest cavities of a few record-setting track cars that wear the Sportcar logo. But before the wins, prior to the recognition, and long before he became an encyclopedia of K knowledge, proprietor and builder Loi Song tiptoed into the iVTEC world in 2005 with this K20-transplanted Acura Integra GS-R.
Back in 2005, swapping K-series power plants wasn't nearly the hit it is today. With so much hype and misinformation surrounding the process, pricing and most importantly, reliability, it's a wonder that we even made it through those early years. But made it through we did, and today 2.0- and 2.4-liter versions of the stout K are staples in the Honda community. And no one knows more about the ins and outs of K wisdom than Song.
Purchased on the cheap with intentions of using the chassis to guinea pig the transplant process, Song began collecting parts almost immediately for the Acura Integra GS-R. In fact, the Hasport mount kit, engine and transmission were already at the shop when he signed the paperwork to take ownership of the DC2 chassis. Tinkering with the car when time permitted, eventually the block was built using JE pistons and placed into its new home. The often-costly ancillary parts made their way onto the long block, and shortly after the Acura Integra GS-R was fired up. After getting acquainted with the car's new heart, Loi swapped out the factory cams and valve train for IPS goods while the OEM intake manifold was replaced with an RBC unit.
Prior to the engine going in, the car had been re-sprayed and given a facelift. Wanting to keep the car as clean and simple as possible once he had it running, Loi added only an Integra Type R front lip to the mix. Gab Sports wheels and Spoon calipers were up next, and the exterior was complete. The original interior never quite made its way inside the car. The rear seats were forgotten, while the front seats were replaced by Recaro SRDs and surrounded by an AutoPower roll cage.
The car served as a test bed for various theories, far too many sets of cams to keep track of, and even traded its K20 block for a built 2.4L version eventually, which encouraged even more testing. Over the years, through trial and error, Loi Song and Sportcar Motion have managed to put together a number of winning formulas based on the K-series platform and the progress never stops.
