I just recently purchased an '05 SRT-4 (have yet to pick it up from the dealership). Now I'm not new to mechanics but I am new to turbo'd vehicles. I was wondering what routes are best for cranking out HP? I'm looking to get close to if not surpass 350-400 HP. I see that Mopar have Staged Upgrades, are they worth it? I'm particularly interested in the S3. Theres also like AGP and GReddy turbo replacements, again are they worth it? Any advice or knowledge would be welcomed!!! Thanks...

 

~400whp on pump gas, over 450 on race:

Stage I computer (non necessary, but helps)
3" Turbo Back Exhaust
3" Cold Air Intake
Return Fuel Line kit w/ Rising Rate Fuel Pressure Regulator
225lph Fuel Pump (or better)
Fuel Management Piggy Back Computer (DTec, AFC, etc...)
Large Front Mount Intercooler.
Blow Off Valve (BOV)
Hard pipes (at least the cold side w/ a BOV mount)
Turbo Upgrade (I used AGP and they've been great).
750cc Injectors
Upgraded Clutch (at least Clutchmasters' FX400 or equivelant)
Upgraded Axles (DSS Stg 3 minimum).

Mopar Stage 3 is nice too, you'd still need (in addition to S3):
3" Turbo Back Exhaust
Front Mount Intercooler
Upgraded Clutch (at least Clutchmasters' FX400 or equivelant)
Upgraded Axles (DSS Stg 3 minimum).

Mopar Stage 3 will get you close to 350 on pump gas and about 380 or so on Race (in High Octane Mode).

 

Thanks for the info bro

 

Also props on your set up too... she must haul ***!!
