Building a new engine for my frst and wondering what gearbox to use etc to take the power. Been told it will produce 330-350bhp and not sure or torque. Not got a lot of money to spend if I'm honest. Been told an ib5 will do the trick but want an LSD too. Any recommendations

 

Got the focus rs box in mine, the other option is a gearbox man stage 2 +

 

Ib5 gearbox with erst s2 lsd.

 

Thanks guys
Do I need different drive shafts or mounts to join the engine to the box and the gearbox engine mount?
