Well after reading the many posts about what type of system to go with and researching everyones systems, BOM, and support, I think there are new "less expensive" but high quality systems becoming available.
I agree with suzuki4life about the cost issue. I don't have $10K to spend on a turbo and everything that goes with building a motor to support it. I don't need 500HP on a street bike but I see that many of the manufactures listed above have entry-level systems priced at $4800-$6000..these systems are basic but upgradeable to the Stage II or race kits for more $
How come companies like JDM and their Chill factory kit can offer a system with all of the components (ie injectors, fuel rail, fuel pressure regulator, etc.) with their BASIC kit that only costs $3700.00? To get these on anyone elses system you need to spend $7K + For me the average Busa owner who wants a little more HP than stock...say 200-250HP this is an attractive and affordable option for me...hell for that price I have $$$ left over for a Trac swingarm, rear sets, shock revalve, and other suspension and brake goodies and still come in less than a Basic turbo starter kit from other manufacturers.
