Stupid comment of the day goes to... Matt!
You don't need big horsepower. Learn to f**king steer. McFly has 260rwkw, Z32 mike had just shy of 300 rwkw, Cadmoon has 180rwkw, Benno's S13 was running a stock RB20 with factory gear and they would all run after up Nebo, glorious or around LP faster than you.
Coilovers, sway bars, strut brace, decent tyres and learn how to use a clutch and steering wheel properly.
I don't want to hear any one else encouraging p platers to mod their cars in an illegal fashion. Yes, a 30 in a 33 is illegal. The motor wasn't an option and hence would require a blue plate.
Time and time again, the guys who've done it have said that it's not a great idea and have outlined the reasons why. If this doesn't suffice, contact someone else via pm. Colin had a pretty decent 32 and his advice is valid. If you want to play with the big boys, listen to the advice try give. If not, you will be a statistic and create more grief for the community as a whole.
