    Q: I have water in my trunk or moisture in my tail lights
    A: Replace the tail light gasket. Recommendation: Spend 28c vs $15 by cutting your own out of craft foam. It's the same stuff and costs much less!

    See DIY Repairs Section for Replacement Procedure


    Q: Why is my ABS Light On? thread

    Real vs Knockoff Brembo Rotor Identification


    Q: My Defroster is not working thread

    Q: My Steering wheel mounted controls (horn, cruise control, and/or radio buttons) have stopped working.
    A: Replace your clockspring / Cable reel.

    See DIY Repairs Section for Replacement Procedure

    Q: How do I hook up my IPOD or other MP3 player to my factory Bose Stereo?
    Suggested Options: thread

    See DIY Modifications and Upgrades Section for Install Procedure

    Q: Why does my car not start or abruptly dies?
    A: If you car doesn't start when its hot or has been left alone for a while (overnight) but starts up and runs great the second time without any problems, check your main relay. The main relay controls your fuel pump and the solder joints within the relay wear out over time. This is a common Honda problem.

    See DIY Repairs Section for Replacement & Reconditioning procedure.

    Q: Why is my speedometer not working or erratic?
    A: Replace your vehicle speed sensor.

    See DIY Repairs Section for VSS replacement procedure.

    Q: Where can I buy Bose Speakers & what part numbers do I need to order?
    A: Buy them directly from Bose thread


    Q: My car idles low or has a problem maintaining idle.
    A: Clean your Throttle Body & Intake Air Control Valve (IACV).

    See DIY Repairs Section for Throttle Body and Intake Air Control Valve Cleaning Procedure

    Q: Why do I have an fluctuating idle or erratic idle or fluctuating idle when hot
    A: Low coolant in radiator (due to leak), air in the cooling system, vacuum leak, or BHG thread - includes bleeding procedure thread - why a large amount of air causes overheating thread - example of bad radiator cap

    Q: Stripped Oil Pan Bolt or Leaking Oil Pan Bolt thread thread

    Q: What is the Mystery Plastic Gunk on front of Oil Pan underneath the timing belt cover?
    A: The Crank Angle Sensor "Potting" (sealing) material is melting off. This doesn't affect the performance of the vehicle so you can safely ignore it. thread
    See DIY Repairs Section for a refitting/repotting procedure if you insist on rebuilding it.

    Q: What engine swaps are possible?
    A: In theory, if you have the time (and money), just about any engine swap is possible, just most will require extensive bodywork, engine bay work, pain, and suffering, so again unless you have money burning a hole in your pocket, most swaps with other Honda/Acura engines should not be attempted. On the other hand, there are a few exceptions to what can be swapped and what cannot be installed. Remember, the Legend's engine is a 6 cylinder, and these heavy bodies need hp and torque...not really much point in trying to throw in a 4 banger from an Integra or Civic...unless your heart is really set on it and your pockets are burning your thighs. Finally, just about anything CAN be accomplished if you have the money, boredom, and time.

    ~All Possible~
    - [USDM Type I -> USDM Type II]: Can be swapped easily with no custom mounts or anything...just drops right in (works with Type I ECU, but works noticibly better with Type II ECU swapped also){also works vice versa}
    - [USDM Type I -> JDM Type I/II]: Same as above, just drops right in, nothing custom about it. {also works vice versa}
    - [USDM Type I -> EDM Type I/II]: Same as above, still nothing fancy. {also works vice versa}
    - [Type I heads -> Type II heads/intake manifold]: Possible with a few modifications, this would turn your Type I into a Type II...its just alot easier to do a complete swap than to modify all this.
    - [Legend Type I -> 96-98 TL/Inspire]: Totally possible, since the TLs from these years shared the same C32A Type I that the Legend used from 91-95.
    ~NOT Possible without serious money/time~
    - [Legend -> 96-03 3.5 RL/Legend]: Possible with money, and has already been done by member 'DV8' (do a search).
    - [Legend C32 -> NSX C32]: Requires SERIOUS money, since this C32 engine is wider than the Legends C32, and would require the rest of the car to be completely modified to accomodate this engine. The intake manifold isnt swappable from the NSX either.
    - [Legend -> 99-04 TL/Inspire]: Completely different engines...Legend uses the C block which is laterally mounted, TL/Inspire's use the J block which is completely sideways (transversely mounted).
    - [Legend -> 96-03 CL]: Same as above, the CL uses the J block also.

    Engine Cooling & Climate Control

    Q: Help! My engine overheated! What do I do? A: Review the Overheating checklist. If you need help, please post in the Cooling issues thread. DO NOT START A NEW THREAD! Rest assured, people DO read this thread and your question will get answered.

    A: Check your heater core. thread

    Q: Intermittent A/C Operation (sometimes blows cold air)?
    A: Replace the Fan Control Unit (FCU). This box decides when to engage your A/C compressor and your radiator fans. thread

    Q: My AT automatic transmission shifter is stuck!
    A: Follow the diagnostic procedure thread

    Q: Can I convert my AT transmission to a manual?
    A: Yes, but it's gonna cost money. You are more than likely better off selling your AT Legend and purchasing a 5-speed or 6-speed. If you insist on throwing money away, see theDIY Modifications and Upgrades Section for the Install Procedure.

    Suspension & Tires

    Q: Will XXX wheel/rim fit my Legend?
    A: It all depends on the offset, center bore size, and clearance underneath your fenders. Unless you are trying to fit Legend-specific rims, you will likely need to have the centers bored out to 70.2mm. In addition, your fenders may need to be rolled (expanded) if you are trying to fit larger rims.

  • Bolt Pattern: 5 x 114.3
  • Center Bore Req'd: 70.2mm
    Wheel Offset 1
    Tire Size Calculator - to calculate how wide/tall you should go thread
    See theDIY Modifications and Upgrades Section for the Fender Rolling Procedure.

    Q: What offset do I need to avoid rubbing with aftermarket wheels?
    A: The Offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel. The offset can be one of three types:

    Zero Offset: The hub mounting surface is even with the centerline of the wheel.
    Positive Offset: The hub mounting surface is toward the front or wheel side of the wheel. Positive offset wheels are generally found on front wheel drive cars and newer rear drive cars.
    Negative Offset: The hub mounting surface is toward the back or brake side of the wheels centerline. "Deep dish" wheels are typically a negative offset.
    If the offset of the wheel is not correct for the car, the handling can be adversely affected. When the width of the wheel changes, the offset also changes numerically. If the offset were to stay the same while you added width, the additional width would be split evenly between the inside and outside.

    Offset Required for the Legend: To avoid rubbing, you need to make sure the wheels you get are the following: MINIMUM of +42 offset. +45 and above is higher (This is on a 7.5" wide wheel.) If you go wider than that, you need the offset to be closer to +51, like Fut (18 x 8, +51 offset). Stock offset for the Legend is +65....most aftermarket wheels are in the low 40's to high 30's. Note: Sedans have smaller wheelwells than coupes, so stick with a 215/40 to 225/40 size tire.

    ( DIY)

    Q: Where can I buy XXX wheel/rim?

    World of Wheels

    Q: Where can I find a shop to have my wheels/rims bored out?
    A: Instead of finding a machine shop, try contacting one of the larger wheel & tire shops in your area to see if they have an in-house lathe. The W&T shops with in-house lathes are likely willing to do the job for cheaper. thread

    Summary of All Available OEM Wheels
    Note: All Factory wheels are 6.5” wide, +65 offset

    91-92 Sedan (L, LS) - 15", 20 spokes
    93-95 Sedan (L, LS) - 15", 16 spokes
    91-95 coupe (L), 91-92 coupe (LS), 95 sedan (SE) - 15", 7 spokes
    93-94 coupe (LS), 94-95 Sedan (GS) - 16", 5 spokes
    Premium upgrade wheels - 15", 5 spokes, availible in gold and silver finish (gold here)

    Performance/Misc Frequently Asked Questions

    Q: Is premium gasoline necessary?
    A: No, but your gas mileage (MPG) will suffer so cost per mile-wise, it will be a wash. thread

    Legend Recommended Maintenance Schedule

    Q: Can I fit an NSX Engine in my Legend? The engine code is similar.
    A: No, the NSX engine is completely different and only shares the oil filter. It's physically wider and won't fit without cutting into the frame rails. It may be possible with $15K-20K but why bother. Please stop asking.

    Q: Can I make my Legend RWD?
    A: No. You might as well put an NSX engine into this car.

    Q: What is VIS and how does it work?

    a-l thread

    Q: Is it possible to convert a Type 1 Legend into a Type 2 Legend?
    A: Yes but it may not be cost effective to do a complete conversion (Calipers, ECU, engine, fuel pressure regulator). The most cost effective conversion would be to just replace the Type-I intake manifold with a Type 2 intake manifold, re-use the Type-2's FPR, and then re-flashing your ECU. If you insist on spending more cash, you would get more "bang for the buck" by undergoing a 3.2L to 3.5L engine swap. Please refer to the Engine Section of the FAQ for more details.

    Q: How are the fueling systems (ECU/FPR) different between a Type 1 and a Type 2 engine? A: The fuel maps in the ECU are leaner for the Type 2 (vs the Type 1) because a Type 2 uses a higher pressure fuel pressure regulator. This may account for the sluggish performance some users have found when using a Type 2 engine with a Type 1 ECU.

    Q: Where can I get more "serious" internal engine work done?
    Note: This thread dates back from 2002 so this information might not be up to date. thread on Source for Engine Modification Work

    Q: What do I need to buy to lower my Legend?

    Legend Lowering Suspension Thread

    Q: Are Headers available for the Legend?
    A: Yes. DV8 had custom headers made for his 3.5L powered Legend, OBX headers are commonly available at an affordable price via eBay (among other sources) but require the O2 sensor wires be lengthened, and Stromung is coming out with headers as of 03/01/07.

    DV8'ed HEADERS
    Stromung Headers Thread

    Q: Can I turbocharge my Legend?
    A: Sure. It's still custom work now and engine management is still an issue. Homebrew ECU tuning has grown a lot in the last year so this last hiccup may be addressed shortly. After that, it will just be about money.

    Visit the Performance Section of for the latest developments
    Turbo Thread

    Q: What engines can I swap into my Legend?
    A: See the engine section above for details.

    Q: What aftermarket ECU chips are available for my Legend?
    A: For years, Bayou and Dinan (relabeled Bayou) were the only aftermarket ECUs available. In the past year though, ECU homebrew development has come to the Legend thanks to users like "Beav". If you are interested in upgrading your ECU, you can now choose between obtaining one of the default "mild" tunes made available by other enthusiasts or downloading the toolchain required to do a full custom tune specific to your vehicle. Since the toolchain is designed to operate similarly to the map editors available for other Honda engines, any competent shop with can tune your vehicle with an hour or so of dyno time.
    Note: One should realistically expect no more than a 10% HP gain from an aftermarket ECU chip with a naturally aspirated engine.
