I'm new to KA's so correct me if i'm wrong but it seems to me that the t3/t04e, along w/ proper engine management (JWT), would outperform a T04B and a FMU????? dont flame, just clarify, thanks
Two words: It's cheaper. Up to about 7 or so PSI, both the Nsport, XS and F-max kits should get similar HP. Beyond that, the XS and NSPORT may start running lean and require an upgrade, From what I hear, F-Max can no longer supply the JWT set-up as it is getting difficult to obtain.
To say one turbo will outperform another leaves too many variables. Every set-up has compromises. Depends on what boost level, the airflow of the motor, intercooler efficiency, the turbo's specs(A/R, trim, etc). Both the T04B and T04E compressors are well suited to the KA. The difference may lend itself more apparent in higer boost levels and flow, but should not be too significant. Especially if the intercooler is decent. The T04B will have better exhaust flow than the T3 turbine. This results in less back pressure for the same boost which frees up more HP. The T3 turbine can actually start to choke the motor at higer boost anf/or RPM's. Though, the trade-off for the T4 turbine of course is lag.
