I recently finished building a B20 LS Vtec - bottom and top end. I am now looking to turbo it, with a bit of a kick in the ***...I want to know if its possible to twin turbo a Civic with this engine? If so, where should I look for the parts? And what parts to I have to get to complete this project?

where do you look for parts? you don't most everything is going to be a one off piece IMO not worth it DRT has a TT civic i love that car but don't see any acual gain it has over any other of the competition. Also so was apexi's drag integra yet agian no substantial gains over over any one else it was competting with. And remeber you have 2 cylinders spooling 1 turbo so you have to choose correctly. IMO not worth it just uby a rev hard or drag kit and call it a day.

 

Twin turbo a 4cyl? .. you'll just have more problems, and overall not worth it... if it was a V6, yeah...
Stick to 'only' one turbo...
