I and my friends have being speaking with HDi (Hybrid Development International Pty Ltd) for a group buy of HDi-GT2 intercooler kit for VR4 twin turbo(6A13TT). These are quite expensive items and go for around AUD $735.00
plus shipment cost in Australia. In the x’mas sales, the price reduces to AUD $618.00
plus shipment cost and they told to me, if the order is 10kits or more, they can give more discount to me.

If anyone have interest, please feel free to let me know or contact to me and leave you contact. My email address is firstname.lastname@example.org
I hope we can have the best price to buy the intercooler for increase the performance of our VR4
