hi, its been a while since i was on here and no doubt things have changed massively in the tuning world... but what im after is peoples advice on how to achieve the above hp... now i know a lot of people used to go down the greys and t34 route but that seems a little dated now???? please correct me if im wrong

i want to keep transmission out of this thread as its not about that... all i want is YOUR opinion... and beforte anyone says talk to your tuner, yes i could do that but i prefer reading what you lot think first...
car in question is saff 4wd and the reason why i want 400bhp is in my opinion its a good useable road car...
thanks in advance gaz.......
