he owns a GSX-R. this is his girlfriends ride. what i recommend is browsing your local craigslist every day until you come across a cheap D16A6. people swap them out all the time, and depending on where you live, you can pick up a mechanically sound one for under $500 for the engine and trans. will save you the tearing down/rebuilding part of your build, and literally everything on your engine will transfer right over to the D16A6. she should be pleased with the A6, it's practically doubling the power of the HF.
