You know what's a better buy? Buying a car that has 410whp stock. Probably cheaper too.I have a 2016 WRX. l am currently pushing 360WHP. However I want to be between 400-410WHP (MAX). Transmission is stock, Engine is stock, and so on. I already know what I need to have done to the engine. I am however in need of assistance of wether or not the stock trans is okay with that amount of hp, and tq. (I think it might be okay), but should I just upgrade the gear box, or just swap it out with an STI transmission? Also what other things do I need to look into upgrading? Drivetrain I'm thinking, but I don't know which one. My heads kinda all over the place on this to be honest, and don't know where to begin. (Yeah yeah why don't I just get an STI, or a V8, etc etc. Its because I wanted the WRX. If I wanted a different car I would have gotten a different car, but this is the car I chose because I wanted it.)
So any input from people that have this done is much appreciated, and thanks for the help in advance.
