Mazda RX-7

you will need a clean piece off hose to fit over bleeder screw on slave cylinder.stick other end of hose in a clean jar of brake fluid.fill resivoir.open bleeder screw and have some pump clutch pedel as you keep filling resivoir.do this untill no more bubbles come out hose in jar.if this does not work may have bad clutch master cylinder or slave cylinder.most likely slave cylinder is bad very rarely does master cylinder go bad.to ckeck slave cylinder just pull back rubber boot if you see fluid come out it is bad.

measure voltage before it goes to the pump, either at the fuse of just before the pump. if voltage is for example 12v at the fuse then 8v after the pump then yes you need a new pump. if voltage is 8v at the fuse or before the pump then its not the pump and you have some other electrical issue.

not sure if they have a relay on your model dude, on a third gen you have (in order of electrical flow) the follwoing electrical components

Battery,

Ignition Switch,

Fuel Pump relay,

Speed Relay,

Fuel Pump Resistor,

Fuel Pump Fuse,

Ground located in boot (near pump) measure the voltage at each of these locations and you should be able to see where the fault is.

if you don't know this, you shouldn't drive an rx7...look at the engine...do you see a turbo???

Do you mean you have no spark?? if so, start with looking at the coil packs usually these are the main reason for no spark, if your coil packs are good then work your way backwards with the electrical system. posible ecu fault

$3000.00 for realy good condition............

RX-7 4V is 4.2 - 4.4 quarts

RX-7 FI is 4.4 - 4.7 quarts

for 1981-1990 rx7, it is recommended to run:

above 15*F (-9*C) - 20w40, 20w50

above -15*F (-26*C) - 10w40, 10w50

-15*F to 85*F (-26*C to 29*C) - 10w30

Below 32*F (0*C) - 5w30

below 0*F (-18*C) - 5W20

for 1991

above -15*F (-25*C) - 10w30

Below 32*F (0*C) - 5w30

vielside rx7 goes about 538mph thats how fast it goes because vielside uses 1234 horse power v8 engine doubled with n20 to make it more faster.

yes - its on the inside of the plastic cover.

i would assume as you asking this question that you don't have the cover??

in that case your best bet is to ring Mazda and give them the serial number of your car and order a new cover- howver they will probably make you buy the whole fuse box and knowing Mazda you are probably looking at over £50 (that's 100+ dollars to the people on the other side of the pond)

failing that Google search and you may get lucky but who knows whether the way the fuses were arranged were the same for each model year???

if you could find another person with a 91 RX7 with the same model name and similar optional extras then you can be pretty sure the fuses will be in the same order.

cheers.

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!

RX7 means - Rotary Experiment 7

Positive cable from battery to starter is bad

Starter motor solonoid may either.

1) need to be gently tapped with a hammer

2) need plates 'un stuck'

find your solonoid at the back of your engine and tap it, should loosen the pin and provide a jolt of electricity through the relay and into the starter motor.

mine does it sometimes since i installed apexi pfc. 93 rx7

Anything will work as long as you have enough money. There have been LS7 swaps into newer RX7's but i'm not sure about an 87.

okay it all depends on what model it is a first gen a fc3s or fd3s there all around 500-20,000 depending on which one.

If your RX-7 is smoking at startup, it could be due to a few reasons. Common causes include oil leaking into the combustion chamber, often from worn apex seals or oil control rings, leading to blue smoke. It could also be a sign of coolant entering the engine if there are issues with the water seals, resulting in white smoke. Additionally, a rich fuel mixture can cause black smoke, indicating potential fuel system issues.

Your apex seals might be bad, your engine may need a rebuild!

I believe your 85 probably puts you with a 13b under your hood. I cant say for certain the location is the same as the 12a, and I hope for everyones sake they saw their error and moved it somwhere sensible. But if not,and its the same as my 12a was the task ahead of you is insanly more difficult than it should be.The freeze plug {one} is located on the back of the block behind the flywheel,{manual trans.}And to access and replace it I had to drop the tranny and flywheel. After attempting this with engine in the car only to discover I didnt have room enough to get the leverage on a giant breaker bar to remove nut on encentric shaft.{no air tools}I highly recomend you just pull the moter. Your going to be time and nerves ahead. Note: Only the 84-85 GSL-SE models had the 13B. GSL and GS have the 12A. Shouldn't be different either way.

When you mean its blowing out white smoke... you mean out from the exhaust pipe right? Not anywhere from under the hood or inside the car? Usually when white smoke comes out the exhaust it means that its not burning the fuel all the way... smell around if it smells like gas. If you smell fuel then check things like the fuel injectors - they can be leaking and need replacing...or maybe just the injector ring need 2 be replaced. Check compression. Check if their are any vacuum leaks and check intake system.

hey bro it sounds like ur coolant seals are bad

Check this link out. There is tons of info on this forum. Scroll down a bit on it, there is another link that describes how to drop a turbo into your 7.

it has two or three rotor's that spin generating power its the same rx7s and black hawk helicopters both have rotary engines. Its been proven that some rx7 rotary engines can push an upwards of 900 hp. Without any assistance from a turbo, or Nitrous Oxide Systems

on drivers side of engine below bypass air control valve near oil fill cap two wire connector.

yes

$3,500 for the engine.
