  • V6 Camaro & Firebird Modification List (where to start and where to go from there)

    I've decided to put together anything and everything possible about the V6 Fbody in one simple guide. First of all i would like to thank everyone who is involved with helping me make this guide for the rest of the members. For those who see something not included in this guide feel free to shoot me an email and i will add it as soon as i get a chance.

    Things covered in this guide will be everything from a complete bolt-on list, install guides, common acronyms,website links, repair guides to write ups on different products for the V6 F-body.
    Absolutely everything you can think of can and will be covered in this guide.

    **(to other forum mods id like to also put links to your stickies in here also if you dont mind. let me know if you want to be a part of it or not via email and we can go from there.)**

    please bare with me right now,im still getting information put together as i or other members find it, and will update anytime i get the chance to do so.


    ps- something you need to keep in mind while reading this and something that you need to understand, dont assume that all cars respond the same to modifications. THEY DONT. so please dont ask questions like, "how much power will this mod give me over this mod" or "is this going to give 10hp or 15hp?" we can give you a ballbark figure, but thats it. the only way to know the exact amount that each mod gives you is to get the car dyno'd.

        F-Body basic model comparsion


        Camaro - Base v6- 3.4L V6 from 1993 to 1995 1/2 and 1995 1/2 to 2002 came with the 3.8L V6 (RS is an option available in certain years and had the Y87 performance package) the V6 came equipped with either the electronically controlled 4 speed automatic transmission known as the 4L60E or the T-5, better known as the 5-speed Manual Transmission.

        Camaro Z28 - same body as v6, but upgraded suspension, and the v8 drivetrain. (V8 drivetrains were as follows 93-97 had the LT1 and some 97s had LT4s and 98-02 had the LS1. Later year Fbodies had LS6 intakes and better Exhaust manifolds. both could be had with T56 6speeds. 93s had M28 and M29 6speeds)

        Camaro SS - Appearance upgades, suspension upgrades and v8 drivetrain *produced by SLP. (same as above for engine and tranny specs)


        Firebird - base v6 (Y87 performance package and W68 sport appearance package was available for most years) *see information for V6 Camaro above*

        Firebird Formula - v6 body with v8 drivetrain (see Camaro Z28 above for more information)

        Trans Am - V8 drivetrain, suspension upgrades, apperance changes (same as above)

        Firebawk - Apperance upgrades, suspension upgades and v8 drivetrain produced by SLP.

        Base V6 horsepower numbers:

        *these are flywheel numbers. not what is actually put to the ground on a dynometer*

        3.4L V6- 160hp @ 4500rpm and 200tq @ 3500rpm

        3.8L V6- 200hp @ 5200rpm and 225tq @ 4000rpm

        Engine Specs:

        General Information by model year:

        Rear end Gear codes are as follows:

        GU2=2.73- v8 only
        GU4=3.08- open differential(means no lsd)

          Bolt on list

          Intake: increases the air flow that comes into the engine, which increases horsepower and tourqe.

          K&N FIPK (FIPK stands for Fuel Injecton Performance Kit)
          SLP CAI
          Lingenfelter Super tube CAI
          Whisper Lid (only available for the 3.8L)

          there are also Ram air kits availabe for both the 3.4L and the 3.8L

          Exhaust: increases the air flow that exits the engine and goes hand and hand with Intake modifications. by going to a aftermarket catback exhuast system your car should see nice HP and TQ gains along with a little bit better fuel economy.

          for more information about exhaust: https://www.camarov6.com/forum/techn...-pressure-myth

          Catbacks: an aftermarket exhaust system that replaces the stock exhaust from the Cat converter on back to the muffler and tips.

          SLP - Loudmouth I and Loudmouth II, Two on the Left (2OTL)
          Pacesetter TFX catback
          Texas Speed & Performance Rumbler catback
          Hooker Catback
          Flo pro catback

          for sound clips of exhausts:

          Headers: headers futher increase the flow of exhaust, the end result is once again more HP and TQ. Headers replace the stock exhaust manifolds. *please note that later year 3.8L(2000 thru 2002) fbodies came with much better flowing tubular exhaust manifolds, and headers wont provide much more performance over the stock manifolds.*

          RK Sport Headers - available for 3.4L and 3.8L applications.
          Pacesetter Headers- also available for the 3.4L and 3.8L
          Clear Image Headers

          High flow-cat converters: high flow cats replace the stock catalytic converter to increase exhaust flow.

          Carsound cats
          Catco cats
          Random Technology cats


          Sub-Frame Connectors: Tube'd or Box'd versions that connect the front section of the car's frame to the rear section of the car's frame providing a more stable and tighter handling ride.

          Sway Bar Kits: Keeps the car from "rolling" in the turns.

          Torque Arm: One end connects to the rear end of the transmission and the other connects to the Rear End housing. Helps keep the car planted without robbing the car of Tq and HP.

          Lower Control Arms: Connects the axle to the rear subframe. Aftermarket LCA's replace the stock stamped steel. LCA's with more solid/rigid units that are generaly bought to greatly enhance straight line performance. Generally used to eliminate wheel-hop as well.

          Panhard Rod: Used to align the rear end once the car has been lowered or heavily modified suspension wise. Greatly increases the cornering stability and helps keep the back end of the car centered under hard cornering situations.

          for a more in depth look on suspension see:




          Gears: changing the rear end gears can greatly increase your vehicles acceleration but will slightly reduce your top speed.

          GM, Richmond, Motive

          Limited Slip differentials: (LSD)

          Zexle -Torsen LSD
          Aubun LSD
          EATON posi

          for more information about LSD:


          Transmission upgrades:


          Shift kits: shift kits firm up the shifts of the transmission. they do not add horsepower but will help inprove quatermile times a small bit. the down side to shift kits are that they will in most cases decrease the life span of your transmission due to increasing the line pressure for the transmission.

          B & M Shift Improver kit
          TransGo Shift Impover kit

          What is a stall?by a member here by the name of husker:

          Automatic cars have no clutch to disconnect the engine from the transmission, so a torque converter lets the engine continue to rotate while the gears and wheels stop.

          A torque converter is a fluid coupling, which allows the engine to spin somewhat independently of the transmission. If the engine is turning slowly, such as when the car is idling at a stoplight, the amount of torque passed through the torque converter is very small, so keeping the car still requires only a light pressure on the brake pedal.

          If you were to step on the gas pedal while the car is stopped, you would have to press harder on the brake to keep the car from moving. This is because when you step on the gas, the engine speeds up and pumps more fluid into the torque converter, causing more torque to be transmitted to the wheels.

          The housing of the torque converter is bolted to the flywheel of the engine, so it turns at whatever speed the engine is running at. The fins that make up the pump of the torque converter are attached to the housing, so they also turn at the same speed as the engine.

          The pump inside a torque converter is a type of centrifugal pump. As it spins, fluid is flung to the outside, much as the spin cycle of a washing machine flings water and clothes to the outside of the wash tub. As fluid is flung to the outside, a vacuum is created that draws more fluid in at the center.

          The fluid then enters the blades of the turbine, which is connected to the transmission. The turbine causes the transmission to spin, which basically moves your car. This means that the fluid, which enters the turbine from the outside, has to change direction before it exits the center of the turbine. It is this directional change that causes the turbine to spin.

          Stall is the speed (engine rpm) at which the fluid is being forced to spin the turbine at such a pressure that it essentally locks the engine to the transmission gears. If the tranny gears (and wheels) are not allowed to spin, the engine will stall.

          Torque converters with a higher stall will allow the engine to rev higher before launching the car. The higher an engine revs, the more horsepower it generates (to a point), so if an engine is allowed to rev higher before forcing that power to the road, the more power is delivered.

          You can also think of it the same way as a manual tranny with a clutch. The higher you rev the engine before feathering the clutch (or dumping it) the more horsepower is put to the road.

                                not sure what some of you guys with 3.8l's and 4l60e trannys are doing for converters. None of the typical converters that fit this tranny and v8 models...
