I’m new on here & just wanted to say Hello 👋🏻

I’m a massive Subaru fan I have owned 3 since 2017

impreza 2002 N/A bought it & found out it was a complete rot box 👎🏻

Impreza gc8 1998 (bought with head gasket failed as a project) supposedly pushed 320bhp but never had a print out

impreza gc8 2000 (currently own this) supposedly pushing 260bhp but again no print out

I was just looking for some advice. I’m looking to try get my Subaru to push around 400bhp but heard it has a potential to rip the 5 speed gearbox apart I was just wondering if there’s any way you could re enforce the 5 speed instead of going through all the hassle of converting to 6 speed?
