look on D series web sight there's a guy on there that turbo AND super charged his D16Y8 and he killing all the records on the track for FWD cars. I plan on doing this but its super expensive but hey how many people do you see with a turbo and a supercharged anything? imagine beating vets and vipers and any other nice car on the road and then saying "yeah I drive a civic" you could also boost the b series and get more horsepower but it will be even more expensive than the d series engine. just my .02
