### Description

690whp 2009 Honda Civic SI Coupe in Nighthawk Black Pearl with 157,000 (Chassis) miles for sale! This FG2 Civic packs built K24a4 that’s paired with a GTX3582R T3/V-Band .82A/R turbo, and mated to an OTL Racing built 6-speed manual transmission. Further equipped with a myriad of modifications, most of which were installed within the last 8 months. The transmission, fuel system, and cylinder head build/refresh only have a few hundred miles. This setup yielded 690whp/480wtq @ 20psi on E80 fuel with more boost still available. Comes equipped with many Boostleetuned Honda Flashpro tunes including a safe road trip capable flex fuel tune for running 93 octane, E85, and ethanol mixes. The E85-only maps are more aggressive on boost, timing, and RPM. The car looks and sounds stock until the turbo system makes noises, it’ll get 25+mpg on the highway with E85 and its current gearing. The built transmission/tall gears result in excellent highway manners, and boost-by-gear for traction on the street. Oil changes were performed every 500-1500 miles with Mobil 1 and a Honda OEM filter, followed by Royal Purple Mesh transmission fluid. Cold A/C was recently recharged, hot heat, functional sunroof, touchscreen Pioneer Bluetooth head unit with a microphone, and 0 gauge OFC subwoofer wiring still in place (removed the subs due to weight). This is the ultimate daily driver OEM+ sleeper that the owner dreamt up, weighing in at 2750Ibs without a driver as is. The owner can provide his IG/YouTube for many pictures/videos of the build! There are currently 10K miles on the build, receipts are available as well! Clean title!
