Twin Turbo

I was wondering what would be best a twin parallel, sequential, or single turbo set up? My car is being designed for drag and most people say single for drag. They say look at supras, but supras are inline and im not sure if that makes a difference but it seems to me it would. I was also wondering if there is enough exhaust from just two cylinders to move the turbines. People say have two small turbos but y do they have to be small cant they an ok size each n use a shot of nos to get them going? I dont have to worry about space because im only using the engine im not puttin it into a wrx. Idk if any of this is even logic im jus tryin to figure everything out. Dont say i havent read about turbos i have been but im on a very large lack of sleep so its hard to fully understand everything right now. Also there are so many factors so i wanted to specify a little, ill be using a EJ20 or EJ25 and wont need to worry about space also ill have a aftermarket ECU. Thanks everyone for your help.

Most people building a drag specific Impreza go for twin turbo. If you go with a small enough turbo (which is ideal for drag since bigger turbos take more gas to scroll) you will have more than enough exhaust from 2 cylinders to spin them.

BTW, there are plenty of twin-turbo Supras out there tearing up the track.

Thanks for your help and i kno there r good twin turbo supras out there but everyone always say look at people w/ supras who upgrade to single so that must be better. Thanks again for helping me out.

I think most of the people doing a single conversion on supras are building dyno queens
