The Story

Finally had the urge to do a real build after not messing with cars in 10 years. Picked up a 2004 Honda Civic Si. It was in pretty rough shape oil leaks, interior pieces missing, and the paint is absolute demolished. But the body was straight and no rust being it was a Florida car. Started off slowly just fixing a little bit here and there. I was able to get some ep3 seats that are not mangled and got almost all the interior parts replaced that were missing. Car is currently waiting on its k20-24 build that's expected to make about 260 whp. Working on getting some Tein suspension and have all the type r side skirts front lip and rear lip siting waiting to be installed. *future update has the k20/24 in. waiting to get it tuned. Just doing brake in miles now. *future future update got tuned at humble and it now makes 257 whp and 201tq with a redline of only 7800. She rips
