twin turbo

if i change the the turbo to a twin turbo do i need a new intercooler as well or would the other work

you have an I4 Turbo right?

i guess its the factory turbo that came with it

I4= Inline four cyl engine
4 banger means one pipe of exhost and one header. twin turbo would not work, you need 2 exhost pipes, one for each turbo.

just get a turbo upgrade the older engines can handle the boost. Will put big number.

thanks
