Hi all,

I have owned (as stated above) a JDM WRX 4EAT bugeye for around 2 years ish now, not so long ago i had to have the gearbox rebuilt, and due to this i am confident the box will safely handle around the 500 bhp mark, i dont intend to take it that far but my question is does anyone know what is needed to take it around 400 to 450 ish, running it for 2 years as standard has been ok but now i feel i need more out of it

Thanks in advance for any replies
