2015 Honda Fit GK5 Time Attack NA Build

The story

Bought in Florida right after moving back to the US, marking the end of my military career. As a daily, I didn’t have plans initially, until I met the community! I then adopted the goals of another member of the group to be a high compression, all motor, fastest L15B1 in the US. I would have save so much money if I wasn’t pioneering this thing so I’d say I love the path I went down and glad it wasn’t easier. Now, I can share my experience with other in the group. ~My 212hp Build~ My build includes so much, of which you can view on my youtube and Instagram. https://youtube.com/@cantfit1877?si=FbGSaxbiCBQlfYcg CNC Innovation intake manifold (with the option to convert to port injection).
