Lovely car JDM twin scrolls are fantastic, shame about the piston going, its either bad fuel or poor map unfortunately, its normally det that breaks those as the pistons dont slap in them but do contain a high amount of silicone to make it harder, but more brittle.
Glad you have it sorted now and she looks to be a bit of a monster

 

Yeah, when I got it - it had Andrew Carr's map on, and just didn't feel right, was a bitch to start from cold and boost fluctuated a lot (once I installed the gauges to check), got it booked in with Andy Forrest ASAP, and he sorted every problem i had with the car but guess the damage had already been done - and doing the ¼ miles at the JGM Shootout tipped it over the edge
