DIFF BETWEEN TWIN TURBO LEG AND CLASSIC
 

hi. what is the difference between the old legacy 2.0 twin turbo and classic wrx which is single turbo. what is more powerful. do the legacy's have stronger bottom ends and could you fit this to a classic wrx. cheers

The engines are exactly the same. However the legacy has a slightly different intake manifold, at least I noticed that the fuel rails are different.

Just switch your WRX intake manifold over and you're good to go.
