When I get my jdm gsr, It will be the complete swap kit from hmotorsonline, the b18c-sir-G...(thanks HAN)...Can I use a turbo kit built for a USDM (b18c1)GSR? Or will I need an engine specific kit? (I'm asking this because of the different compression ratios from US and Japanese GSR's.......USDM=10:1.....JDM=10.6:1
