2.4 Performance Mods

[cobalt123]

Intake: The stock air box is highly restrictive. Freeing this up would provide more air for combustion and increase power output Cold Air Intake Injen >> AEM Rebel Autoworks (RAW) Advanced JDM >> Short Ram Intake K&N Typhoon 2.4 specific >> GM Performance Parts >> AEM Z-spec/RSM Racing >> Weapon R >> Air box mod INFO Intake Manifold Hahn Racecraft INFO Vulcan Turbo >> Kinsler Fuel Injection (optional upper rail kit) >> Exhaust: The less restrictive an exhaust setup is, the more power will free up from an engine. Our 2.4 stock exhaust system is decent (has 2.5" piping), but it is restricted by the header, cat (in the downpipe), and the exhaust section from rear wheel back (which becomes 2.25" piping and has a restrictive muffler) Header (Exhaust manifold) Long Tube (high-end gain) Weapon R Race Header (with downpipe, no cat) JBP Vortex Header >> Mid-length (mid gain) ZZP Midlength Combo (with downpipe, optional cat) >> SLP Combo (with downpipe, cat) Vibrant Header Combo (with downpipe, cat) OBX Pacesetter Header Clear Image Automotive Header >> CTI Race header (optional cat) >> Shorty (low-end gain) CA Header V1 (not produced anymore) CA Header V2 Shiny-Hiney (identical to CA V1) >> DC Header Hahn Racecraft GM Performance Parts Stock Extruded and Honed BADMAB Industries >> ZZP Header Turbo (for turbo applications only) Vulcan Turbo Downward Manifold Vulcan Turbo Equal Length Manifold Downpipe XTC Downpipe (optional cat, 2.5" or 3") ZZP Downpipe (optional cat, 2.5" or 3") Stock LSJ Downpipe w/ cat INFO (requires some modification for the Auto Trans.)

Tuning parameters like power enrichment delay, air to fuel ratio, and spark timing will result in decent horsepower gains. Tuning after installing bolt ons (intake and exhaust) will further bring out the potentials of those modifications Tuning Equipment INFO Hptuners >> (doesn't support 2008 ECM yet) EFI Live >> (doesn't support 2008 ECM yet) LS2-Edit >> Trifecta Performance Tuning INFO AEM F/IC >> Canned Tune Vector Motorsport >> Jet Performance Chip INFO Westers >> Legend: >>= Link to product Videoclip= video PIC= Picture INFO= Additional information on product OK I think I got everything that wasn't added from the last thread. If you see something missing or a link that doesn't work just post it up and I'll add it. Also if you have a video clip or picture of your exhaust that isn't already up please post the link and I'll add it.
