Strip mods, sell the 205 (assuming thats what you have), throw in a EJ257 and realise how much torque you will have. This works better in GC8's however as they are lighter.

But you have to tell yourself, how far are you willing to go? If 315hp isnt enough, what will be? 15k wont get you a hell of alot further in my opinion. Look at wai, and see howmuch he has spent. Although this is a big figure, if you constantly require more power, you may end up in the same situation.
