Mazda RX-8

offsets are determined from center of wheel front to back if bolt holes are front of center then its front-spacing if behind center it's back-spacing measure wheel front to back and then lay wheel on front and measure to back of bolt hole that gives you offset if any.

On top of the radiator right next to the fan

it is not practical to change the head unit on a RX8

The above answer is correct.

There are many ways to make an after market head unit "fit" into the RX8, but you will probably lose the steering wheel stereo controls.

You can connect aftermarket amplifiers to the stock head units speaker output and use aftermarket speakers. Get the MP3/CDROM addition for the stock CDROM head unit from a Mazda dealer.

Mazda rx8 goes 0-60 in about 5.7 seconds.

Jetta GLI goes 0-60 in about 8 seconds.

Jetta is a compact family sized sedan, while the Mazda Rx8 is a sports car.

Obviously the Rx8 wins.

remove plug wire from top of valve cover .you will need a 6inch ex for rachetand a 5/8 plug socket.losen and pull up thru hole.

Mazda USA doesn't allow the use of synthetic oil for warranty support on rotary engines starting with the 2009 model year, it will void the warranty. Prior to that, they only recommended conventional oils; but, because they did not explicitly disallow synthetic oil in the owners' manual, they can not legally void the warranty for use of synthetic oils. That would violate the Magnuson Moss Act.

Japan, Europe and all other countries suggest synthetic oil.

Mazda in Japan sells group IV synthetic oil expressly for use in rotary engines.

Mazda's rotary racing teams run synthetic oil.

Rick Engman, who has built more race winning rotary engines than anyone in the USA does not recommend anything other than synthetic oil in rotaries.

The reason for the myth that you can't use synthetic oil in rotary engines is twofold. First, when they first came onto the market decades ago, the additive package included with early synthetic oils caused some elastomer seals to swell and fail. This issue has been resolve for a very long time. The second issue is how well particular synthetic oils mix with gasoline when injected into the engine to lubricate the apex seals, and how well and cleanly those oils burn off. Because Mazda N.A. does not have the research or legal budget to allow them to recommend some synthetic oils and not recommend others.

Shift it around 4.5k RPM. Don't go under 3k when driving or else you start wasting gas.

yes. look up supercharged Mazda rx8 on youtube

Check out Pettit Racing on Google.

10 - 12 PSI of boost in a RX8 is about 330 - 350 RWHP.

--- check out rx8club.com --- lots of good information on there to find out about your Mazda rx8, I have an '05 that I'm building up for turbo, everything you need to know or need to search about is posted about there...

There isn't one that is "faster" and it depends on you're definition. Engine speed and the car's speed both can be defined as how "fast" it is. I'll try to answer for both cases.

If you mean engine speed (rpm), then yes and no. They typically are able to turn over at a much faster rate than piston engines because the inertia is evenly distributed into a circular pattern in the triangular rotors. In a piston engine the center of rotation is not the center of gravity (those points are one and the same in a rotary) and therefore centripetal force is unevenly applied to the cars internals. This makes high engine speed very tedious and expensive work (ie Honda s2000, BMW m3, Lexus lfa, etc) or failure will occur. Rotary engines on the other hand can be made to operate at high engine speeds without much extra in terms of cost. They do have limitations however. Heat distribution and complexity for basic repairs are two big ones. You can find more with a quick google search.

If you meant overall speed of the car, there is no way to tell. The size of the engine, size of the car, aerodynamics, etc would dictate things as well as the simple difference in engine type. Rotaries do produce a higher amount of power per liter in almost all cases over piston driven engines, however.

Hope that helps!

You need to buy hot start spark plugs which go on the leading plugs chamber.

MAZDATRIX carries them

Very easy. Jack up the car on the left side and the park plugs are an easy access on the left side of the motor. Unplug the spark plug wires (make sure not to mix them up when reconnecting). Use a spark plug socket to remove them and replace them.

Yes. Mazda sells it as being a sport car, and the owners say the same. So It must be a sport car.

There is no "timing belt"

There is also no camshaft nor any valves.

The rotary engine does not use any of the above.

This will also explain the fuel injection part of the engine, I think this is what you are looking for.

Evap pump

Move down? Yes, there is a level on the left side of the seat that you need to pump down to lower the seat and pump up to raise it.

For the 4.6L it's a fairly involved job and I wouldn't recomend it unless you are getting close to 100K miles or are having misfire problems. For the 4.6L it's a matter of removing or loosening the items that are in the way (such as the air cleaner drum and hose leading to the throttle body, as well as the electrical interface plugs and relays mounted on the firewall in the engine compartment on the passenger side of the car). Make sure you cover any ports or hoses that you disconnect to prevent dust or debris from getting blown into them. Removing the spark plug boots is usually the toughest part of the job, because there isn't enough room to get your hands in there to pull the boots off. I discovered with mine that a helpful technique is to use a length of strap type rope or cord and loop it around the spark plug wire. Then tie a slip knot in the rope and manuver the loop so it is around the head of the spark plug boot. Gently pull the loop tighter so it closes around the boot (NOT THE WIRE!). Once it's tight you can use the rope to pull upwards to disconnect the boot. Remember that the plugs are slightly angled on the Expedition's heads (towards the rear of the vehicle on the passenger side and the front on the driver's side), so you'll have to pull at a slight angle in order to release the plug boots.

After that it's all very straightforward stuff (blow out the area with compressed air, use a spark plug socket to remove plugs, gap new platnium plugs and use anti-seize compound on the threads of the new ones, use silicone dielectric grease on the boots, torque new plugs to spec, etc.). If you're unsure of how to proceed get a manual from Haynes for your vehicle.

The timing is controlled by the computer... so, probably not.

just over half way

In the main fuse box in the engine bay closest to you on the left bottom it is blue

Yes, however the exhaust manifold makes it awkward to fit a turbocharger. It is more common to place Supercharger in this car.

The easy way is to jack up the drivers side, and put it on a jack stand.

Remove the drivers side front wheel you will be able to reach the plugs easy.

That reminds me, I need to regap mine.

You need Genuine Mazda 5W 30 Non synthetic Mineral Oil. Nothing else.

The intake air temp sensor is included in the MAF sensor.
The power to the MAF is black with a blue line.
The MAF ground is black with a green line.
The MAF output voltage wire (used for nitrous or methanol injection) is yellow with a red line.
