I just get a kick out of how the all people who think it worthwhile to boost a NAxfire have very little experience or knowledge in turbocharging anything.

You can't simply TUNE an ECU to read boost. It needs to have the software inputs to start with. And if it doesn't (the NAxfire has a different computer than an SRT6 and doesn't come with a MAP sensor) you need to perform the required tasks (timing retard and additional fuel pressure or injector pulse) with piggyback equipment. And if you support boost that way you need to ensure the stock ECU inputs (sensors) never go out of range or the stock ECU will throw codes. In a NAxfire you will only get to half a bar (7 psi) before you surpass the largest injector you can run (and still idle with). Not to mention the detonation risks you would be taking with high compression and the weaknesses of a NAxfire drivetrain.

A custom remote turbo setup...

Remote Turbo: Garrett GT35 (Trim? Exhaust A/R?) installed in stock muffler cavity. Fabricate brackets.
Exhaust: Lose rear cats, Y into 3" off center (driver side), maganaflow round muffler?, 38mm Wastegate?, dump/recirc?, into V-band turbine housing, out V-band turbine housing to stock tips.
Charge air: Out of compressor and up passenger side, Intercooler location?, into stock intake.
Oil delivery: RB Racing Scavanger pump to oil cap.
Coolant Delivery: T from heater hose, scavange back to radiator?
Higher Volume Fuel pump (SRT6?)
Aeromotive Digital Fuel Management Unit (increase fuel pump voltage while under boost to match boost)
25lb/hr injectors (enough to support 325hp with the increased fuel pressure but not so large the PCM can't adapt during closed loop with a custom tune).
Timing Control: Split Second FTC1 (-024?) to filter timing and MAF output against RPM and intake pressure to fine tune timing retard and fuel delivery in all conditions (piggyback).
Fuel Pressure Gauge
Wideband A/F ratio Gauge
Boost controller (10psi max for higher resolution)

And that doesn't include all the bracket/piping fabrication, tuning time, clutch upgrade, etc.

Nobody said it can't be done. But those of us with experience know it isn't worth all the cash and risks for just 300hp. And the best part of it all is YOU HAVE AN AUTOMATIC! LOL! What's the point? Just buy an SRT6 (never though I'd say that).
