How do you set the timing on a 89 RX7?

User Avatar

Asked by Wiki User

First you need a timing light which I assume you have. There is a notch on crank pulley,put a dab of white paint on it. Connect timing light, if off loosen bolt for distributor and adjust accordingly.Manual states 8 degrees BTDC @ 800 RPM. This is also assuming that all other components are in good working condition,timing belt etc.

It might cost around 2 to 3000 dollars but it is very risky they ussually dont meet safety standards unless its the rx7 or lancer evolution besides that good luck

What is the function of an intercooler?

User Avatar

Asked by Wiki User

An intercooler, or charge air cooler, is an air-to-air or air-to-liquid heat exchange device used on turbocharged and supercharged (forced induction) internal combustion engines to improve their volumetric efficiency by increasing intake air charge density through isochoric cooling. A decrease in air intake temperature provides a denser intake charge to the engine and allows more air and fuel to be combusted per engine cycle, increasing the output of the engine.

Having problems with your rx7 1988 cant turn on when it was working there was white gray smoke coming out ot the muffler what can you do?

User Avatar

Asked by Wiki User

My 88 had this problem. It was the sub-zero starting assist valve located on the underside of the intake snorkel. I disconnected the hose, and plugged it up. Then I cleaned the antifreeze off of the spark plugs. The engine then started up with much white smoke. I live in a warm climate, so I ended up plugging up the brass tube with silicon gasket sealer, and disconnection the power to the reservoir pump.

Pulsing idle on your 88 rx- 7?

9 times in 10 it's the result of a vacuum leak. It could be the TPS out of adjustment though.

1987 Mazda rx7 non turbo and you believe it over heated you think the apex seals got mesed up because of that or could it be somthing else it seems like theres no compression please help you?

User Avatar

Asked by Wiki User

same thing happened to my fc(rx-7) found out that when 13b's start to overheat the engine will run rich(increase the fuel) what you might want to do is check if the engine is flooded look to de-flooding methods. simple to do. normal indication is when cranking you can smell fuel. if not flooded and believed to be seals check compression, normal compression gauges will work if you do the three bounce test look in Mazda tech manual or haynes manual.

Why does your 88 RX7 idle obscenely high...like 5200 RPM?

User Avatar

Asked by Wiki User

When this happens its usually when there is air getting in to the engine when there shouldn't be

try to look in these areas...

possible vacuum leak - to idle that high it would have to be a very big vacuum leak

throttle plates sticking - not likely but does happen. you will have to take off the inlet ducting to varify that they a closing properly.

check ov the intake system to check that air can not get into the engine any other way other than through the throttle body.

after this check if there are any error codes.

check fuel pressure - shouldn't be higher than 50 psi.

if that doesnt shed some light on the situation hook a boost gauge up temporarily and see what the engine is doing - then give it a little rev see what the gauge does and then work from there.

hope this helps.

BEST ANSWER

When all vacuum leaks have be addressed and fixed.(COLD START SCREW "BETWEEN THE TPS AND IDLE SCREW" - JUST TAKE IT UP JUST UNTIL IT DECIDES TO NO LONGER ADJUST, THEN SCREW IT 1/16 OF A TURN AND LOCK IT DOWN).

Now it's time to baseline your Idle (make sure car is at operating temperature)

1. On top of the upper intake, there is a screw which is your idle adjustment screw. Screw it to the right until it can't go anymore(DO NOT TIGHTEN)

2. Adjust your TPS to the left as well (Just to the point where you no longer see it adjusting and then screw it to the right 1 - 1-1/4 turn.)

3. Start your car and if it drops and dies, adjust the idle speed screw to the left a little at a time.

Repeat step 3 until it finally fires up and stays on. Look at your tach and set it to 750 - 1000. I set mine at 1000 bencause it's smooth and i have a good throttle response at that but you set where you feel comfortable.

How much hp does a 13b engine have?

User Avatar

Asked by Wiki User

It depends on the year. As far as second generation cars go it is:

1986-87 non turbo 146 hp1988-92 non turbo 160 hp1988-92 turbo 200 hp

Do not compare these number directly to a piston engine. The rotary applies the power differently. It is far more fun to drive then a piston engine.

AnswerI think the 92 j-spec engine had like 215-220! 93-95 U.S. spec 3rd gen rx7's were TT and I think were rated at 255bhp. That's good horespower for a 2700lb car.

In japan they continued to offer the 3rd gen until 2002/2003 when the rx-8 was introduced. During this time the 3rd gen was vastly improved and horsepower got up to around 285.

How do you de flood fb rx7?

User Avatar

Asked by Wiki User

if you have a block heater, plug it in for at least an hour. this will help evaporate the gas during the next steps

pull the top 2 spark plugs out and crank it a few times with the pedal to the floor. wipe up the mess that shot out, let it sit for 5 minutes. squirt 10CC of plain engine oil into each chamber crank it 3 more revolutions (youll hear 6 "puffs"), reinstall the plugs, floor the gas pedal and crank till it starts. when trying to start it you should ALWAYS crank for at least 10 seconds or you're just going to flood it even worse than before. wait at least 30 seconds between attempts to let the starter cool down and the battery "recharge".

DO NOT USE ETHER OR ANY KIND OF STARTING FLUID

if this doesnt work you have to change your oil because the oil that's getting injected into the chambers is too diluted with gas from the flooding to keep a good seal in the combustion chamber.

also if you don't hear 6 uniform puffs when cranking you may have a blown or sticking seal in the engine

You have to have an engine rebuild which costs from $2500 to $4000 depending on other internals that needs replacing and labour of the shop.

Where do the plug wires connect on a 1983 rx7 12a ie T1 T2 L1 L2?

User Avatar

Asked by Wiki User

The rotary engine has two sets of spark plugs in order to meet the strict US smog requirements. The leading plugs(L1 L2) are the set on the bottom, and are used to actually ignite the fuel. The trailing plugs (T1 T2) are on the top, and are used to clean up the exhaust after combustion. So, to answer the question, L1 is on the front bottom, L2 is the rear bottom, and T1 and T2 are on the top.

How do you adjust the Throttle Position Sensor on a 1990 Mazda RX-7?

User Avatar

Asked by Earlhollis

in front face of the trottle body you will see the TPS (Trottle Positioning Sensor). To the right of it will be bracket which is hooked to the throttle values. There is a spring loaded screw which you can turn with a flat-head.

How does the rotary encoder work?

User Avatar

Asked by Wiki User

A rotary encoder is a type of position sensor which is used for defining the angular position of a rotating shaft. It generates an electrical signal, either equivalent or digital, according to the rotational movement. There are numerous types of rotary encoders like: absolute rotary encoder, incremental rotary encoder Light Duty Incremental Encoders and many other. These encoders are categorized by either Output Signal or Sensing Technology.

No. it does not. breaker bar with 19mm socket wedged on the frame rail hit the starter a few times. good luck not smashing up your thrust bearing. read this http://mazdatrix.com/faq/pulley.htm

Do you have to drop the gas tank to replace the fuel sender on a 1985 Mazda rx7?

User Avatar

Asked by Wiki User

From my experience with RX7s, the easyest way is to drop the tank so you have enough room to get at bolts and clear the lenght of the fuel sender.
