Keep in mind that 1.6 liter twin screw makes this 3.2 flow alot more than say a when trying to size a turbo for 3.2 that wasn't. Sizing turbo''s for twin charged applications is a whole different beast. For the purpose of spooling that turbo doesn't care about displacment. Its all based off of the volume of exhaust gas entering that turbo. which when normally aspirated displacement its a huge variable for that. bleh outa time i will post more later
