Hey bud,
Unless im way out of touch the price is very fair especially considering that it is basicly all new and $1100 cheaper than you would pay for it new.
The car was never fully tuned as mentiond it was only on the dyno for 2 hours and then switched off, but it was pushing an effortless 280kw at the wheels with heaps of response. My other mods are extensive but at 280kw they were of no real effect. As long as you have an exhaust, cooler and injectors, 280 - 300 will be easily achivable on a stock 25.
