Greddy turbo kit's are the all time low kit ( that kit is $3600 ) and a Monster lag compared to newer more updated Turbo's in it's power class. The HKS Cam gears are the cheapest too and prone to slip, no After-market intake manifold either. The injectors are to small, the G-force ECU is outdated and made for the simple man's ride. Your really paying for the body kit and the rim's in my opinion and you could make that car for around $40,000.
