Any engine can be built to be Supercharged or Turbo'ed it seems that your on the right path, $3,900 for all that sounds in the ballpark. The cost will come in labor ( which is enjoyable) my suggestion is do MORE research than installation. Read twice install once. Read once, install, take apart, two or more times. I'm guessing you know that. I'm a 2nd Gen guy, and I'm sure the 1st Gen gents, will assist you along the way.. Let us know step by step. It will be fun to watch your progress - with an additional 50 to 80hp in such a light toaster, that Box will fly and surprise just about any Civic Type R.
