But to answer your question the RX-8 doesn't even have a motor. It is powered by the confused look on Mustang owners faces as they are behind by in a twin turbo 20B RX I thought I could take em". Just call it wishful thinking on my part. Sean answered 13 years ago. It's powered by an alien technological advanced engine with neither cylinders nor rotors.
Oh and by the way It makes no sense to consider it a 6 cylinder because have you ever heard of a 1. And uh Don't say something like that and not back it up. You have no idea what you're talking about. Jonny answered 13 years ago. MIght be a matter of opinion but anyone in thier right mind thinks there stupid little things. Lars answered 13 years ago.

Steve answered 13 years ago. Maybe not a 1. Its not 1. I'm sure that if you look around hard enough you can find some more small V6s. It doesn't matter what the displacement is If I wanted to I could build a 2.
Sai answered 13 years ago. Every single car has a speedometer, but for the ones that have a number displayed, what is it called? Digital mph counter? My car has no compression can any one tell me why what I need to do did everything the manual said to do and watched u tube videos but still no luck help! My listing shows that I have an inquiry.
When I click on it, I get a dialog box saying to check my registered email. A second concern for rotors used near or above 8, RPM is the clearance between the sides of the rotor and the side housings. The construction and assembly of the rotor and rotor gear is such that both sides of the rotor have a portion, referred to as the "land", that protrudes out from the rotor "side" several thousandths of an inch.
For measuring purposes, detailed below, the "land" on the side of the rotor containing the rotor gear is the face of the rotor gear itself.
The "land" on the opposite side of the rotor is the circular portion of the rotor surrounded by the inner oil seal. These features need to be taken into consideration when clearancing the rotor.
The first step in preparing a rotor for clearancing is to measure the thickness of the rotor housing being paired with the rotor at eight evenly spaced points to determine the minimum or narrowest point of thickness of the rotor housing. This minimum thickness becomes the "base line" for the calculation process.
Now, measure the thickness of the rotor and rotor gear assembly at three different points from the "land" on one side to the "land" on the other side. Select the maximum, or widest, thickness of this assembly and subtract this number from the base line number previously obtained.
We have found that the following clearances work well:. Clearance between side housings and rotor maximum "land" width: 12A Engines. This "land" clearance is obtained by machining away material from the "side" of the rotor, thus leaving the "land" extending from the rotor "side" by the specified amount.
It is entirely possible, based on the production tolerances we have seen over the years that you may need to remove as little as. In other words, some of the clearance required already exists. All rotor bearings, stock or Mazda Factory Race MFR , are made from a flat piece of steel which is stamped, rolled, and hooked together at the joint with a "puzzle lock" design.
This bearing is then coated with copper and plated with about. The inside surface of the puzzle lock joint area is ground off to eliminate high spots, usually resulting in a portion of the copper coating being exposed. This appears, to the untrained eye, to be a worn spot on the bearing, but is in fact normal See Photo. Rotor bearings do cause occasional problems during high RPM operation.
It is important to use properly clearanced rotor bearings. In general, do not replace rotor bearings when you are re-using rotors unless they are over the recommended clearance or show some damage from dirt, heat, or lack of oil. Our experience has shown that used bearings in good condition are safer than new, untried bearings.
For most purposes, there are only two choices of rotor bearings technically, there are other models for the 13G 3-rotor, and to fit a 13G rotor to a 13B eccentric shaft, but these are relatively rare.
Both 12A and 13B rotors use the same bearing. The two choices are the stock bearing and the MFR bearing. For high performance street and racing use, the best rotor bearings we offer are Mazda Factory Race MFR rotor bearings with a deep oil groove and additional clearance approximately.
While stock bearings can be grooved deeper and polished to obtain additional clearance, the MFR bearings are still the better choice.
The MFR groove is approximately. While our testing AutoFile, Dec. And in stopping power, the RX-8's feet from 60 mph to 0 equals numbers posted by a Porsche From its sleek titanium gray flanks to its inch alloy wheels, our high-revving, Wankel-powered long-term Mazda RX-8 is all sports car.
But its wide-opening, B-pillarless Freestyle. So what's left to wonder? We've mentioned the engine's possible question marks, which only long-term testing will answer. We also worry about the Wankel's fuel economy, at least at this early stage where we've determined the car's smallish, Our fuel numbers have hit as low as 13 mpg, which is a surprise for a pound sports car that comes with federal fuel economy estimates of 18 city, 24 highway.
Maybe once we settle down and stop running the engine in the torpm range we'll see some improvement, but we're not sure we can live without the Wankel's high-revving wail for long.
We'll keep an eye on fuel consumption and let you know if and when it improves. We also might try a tank of regular octane on the advice of some owners who say the car actually gets better fuel mileage burning regular octane vs.
But if regular hurts performance as Mazda officials predict , you can bet the high-test will be back in our tank in a hurry.
