hi tierney,your going to need a lot more than a front mount to get 380-400 bhp.my advise is to collect all the parts as you have the money ,then bang it all on together a week or two b4 new remap,your going to need a bigger turbo ,3" exhaust ,s/s manifold,bigger injectors and fuel pump and a few other little bits,i only know of two other lads in this club running power that big and it wasnt cheap,as it is, your car is running about 280 brake accorrding to what wes said is done to the car,and it only a matter of time b4 the turbo goes bang as its not healty running 1.3 bar on a standard turbo,check out dave lewis blog on the site
