"The JCsports turbo seems right for you. It has decent power and no lag."
I'm not commenting on the JC system, just the lag statment. ALL turbochargers have lag. Until someone comes up with a massless turbine (that spools up instantaneously), this will continue to be the case. Having said that, I'm sure it's possible the JC system has very little lag if it uses a smallish turbo.
