Adam32,
He has a bigger turbo, HKS pod filter, 550cc injectors, fuel pump, intercooler, full exhaust, Apexi PFC, Apexi AVR, forged pistons, gasket. Has a few other bits and pieces done to it.
On ordinary days he runs it at 0.8bar but he boosts it to 1.3bar when he wants to drive hard.
The best part of it is that he bought it as is and it had only 27,000km on the clock as the guy he bought it from has another 3 cars.
