Serco in QLD are the Australian distributor for WISECO pistons. They sell forgys for 3TGs for N/A and turbo motors from 86 up to 89mm. They will send them Australia wide. You must specify low comp turbo pistons(believe me). Its much cheaper dealing with them direct. If you can get forged pistons for a T series cheaper from anywhere else can you please let me know!

I've had three different T series engines of my own with these pistons and have never had a problem.
