Mazda RX-7

bottom of car under the driver side.....near the engine bay

take it to a mechanic for a diagnostic DO NOT CUT ANYTHING

try changing the oc sensors that worked for me

an fc3s is a 2nd generation you may recognize it as the bodytype like inital d the Japanese cartoon. an fd3s is like the red rx7 in the first fast and furious.

make a mix of 90% antifreeze and 10% distilled water. its only for sub-zero temps so if you live in a warm area i wouldn't even bother.

Hitachi ht-18s ! They are called a sequential turbo . Split pulse! The s4 had a splitter in the manifold to change the flow at low revs by the means of a ecu operated actuator . The s5 just had a split manifold and turbo. A lot simpler on the s5 . Also the s5 was 20hp more powerful than the 185hp series 4. Hope it helps..

All 1st generation RX7's have a 110 x4 bolt pattern, except the GSL-SEs are 114.3 x 4.

For the 87, and probably most, it is located under the passenger side floor carpet. Take off the plastic runner that holds the carpet on the bottom of the door jam, take off the side kick panel, lift up the carpet. You should see a shield that covers the ECU, it is held in place by 4 10mm bolts. Take off the shield and there is the ECU.

The big coil pack goes to the top, the front rotor is number one. they are usually labeled on the block with a L and a T. That stands for leading and trailing. Hope this helps.

The fuel pump is inside of the gas tank. It can be accessed by removing the carpet from the hatch area (hardtop) or the trunk (convertible). The fuel pump will be covered by an oval cover, secured by 10mm bolts.

1985 Rx-7 may be a Series 3 or Series 4, the weights are:

Series 3: ~ 1,130 kg

Series 4: ~ 1,298 kg

worn suspension bushings or steering box. check the idler arms first

try turnning knob directly above head light switch. that retracts them up and down

The power supply is in the drivers side fuse box. Check fuses by the clutch pedal, and under the hood by the drivers side front strut, under the hood.

some rx7 series 3s came out with a 13b motor ,an are only marginally bigger an i owned a series 4 13bt motor in a series 2 rx7 its one of the best engine conversions that you can do add toyota hilux diff with 4.3 centre out of a diesel hilux is much better pick

1. If your Mazda rx7 is no turbo and u don't want to spent alote of money cut the cats off and put a straight pipe in there. you will get less restriction and way less back pressure and better RPMs. ( warrning your check engine light may come on, no big worrys your just getting mor power then ur ECU is use to so you can erase the code).

2. Remove your power steering belt ( your steering will be harder to turn but you can gain somtimes 5-10hp).

3. perfomance racing oil such as sinthetic 10w-30 or 5w-30 Quaker, Penzzoil, Greedy, Summit, Mobile1 ( you can find most of these oils in automotive performance magazines). how ever with mobile1 one don't be surprised if it blackens quicker or you idleling RPMs go up more. HP gains are not very big but you will extend the life in that rotory engine and get better response out of it.

4. If your Mazda rx7 is turbo then upgrade to a turbo timer, better waste gate, better intercooler, open the exhaust up, thicker plug wires, computer chip.

5. if ur on a realy tight budget next time you do a tune up order sum 10.2mm spark plug wires from eBay. they are very cheap on eBay.

6. get a large flow air-intake, nothing worse than watching a monster engine sucking air through a tiny straw.

7. remove the ac unit. Most of them are broken or close to broken, and the unit takes 5-10hp just like the powersteering

DO NOT RUN SYNTHETIC OIL IN ROTARYS

the remnants of synthetic oil, which are usually what aids in piston motors, can slowly eat away at apex seals. never put anything in a rotary that will coat or leave behind residue in rotary motors.

IGNITION SYSTEMThe ignition system is responsible for igniting the air/fuel mixture at the most appropriate time. To understand how the ignition system works in the Mazda rx-7, it is important to have a good understanding of ignition systems in general. We'll start by giving a quick overview of ignition systems and then focus on the particularities of the ignition system in the Mazda rx-7.

This above shows the schematics of a generic ignition system that one could find on many piston engine cars. The Ne signal indicates engine speed. The G1 signal indicates crankshaft angle. With these two sensors, the engine control monitor (ECM) has permanent knowledge of the crankshaft angle and the engine speed and therefore can tell when the spark plugs should be fired for optimum performance. The IGT (ignition timing) signal is a pulse which tells the igniter when the power transistor should switch off the current flowing through the primary winding of the ignition coil. This current is low voltage (12V). When current flows through the primary winding, it creates a magnetic field. When the current flow is cut suddenly, the magnetic field collapses inducing a high voltage current into the secondary winding. This high voltage current creates an arc at the spark and provides ignition. The IGF (ignition feedback) confirms to the ECM that a spark has ocurred.

MAZDA RX-7 IGNITION SYSTEMThere are two rotors in the rotary engine: a front rotor (rotor 1) and a rear rotor (rotor2). Each rotor has three combustion chambers. For each rotor revolution, there are three firing events. The eccentric shaft makes three revolutions for every rotor revolution, in other words, it turns at 1/3 the speed of the rotors. The two rotors are 60 degrees apart from each other.

There are two spark plugs for each rotor. The leading (L) spark plug is the main spark plug. The trailing (T) spark plug is here to complete the burn and reduce emissions. At idle and with no load, the leading spark plug fires at 5 degrees after top dead center (5ATDC) and the trailing spark plug fires at 20 degrees after top dead center (20ATDC). On a rotary engine, top dead center (TDC) happens when the combustion chamber (three per rotors) is centered on the two plugs.

What follows is the electric diagram for the ignition system. This will give clues on how the system functions. Note that the engine control unit (ECU) relies upon an Ne and G signals from the crank angle sensor (CAS) to determine spark firing, as in a generic ignition system. These two signals will not be adressed any further here.

LEADING IGNITIONConsider the leading ignition coil with igniter on the schematics. The B/Y (black with yellow stripe) wire is the 12V primary current supply (from main relay). The G/Y (green with yellow stripe) carries the ignition timing signal (IGT-L) from the ECU. The IGT-L signal is a pulse. When the pulse switches from high to low, the igniter turns off the current in the primary leading coil winding. Since there is only one leading coil and there is no spark distribution, both leading spark plugs are arced. Obviously, one spark is wasted but with no ill effects. The leading ignition system is quite straightforward to comprehend. The trailing ignition system is more complex.

TRAILING IGNITIONThe trailing ignition system is actually a two-coil system (one coil for each rotor). Consider the trailing ignition coil with igniter on the schematics. The B/Y (black with yellow stripe) wire is the 12V primary current supply (from main relay). This wire shows up twice in the wiring diagram since there are two coils. The L/Y (blue with yellow stripe) carries the ignition timing signal (IGT-T) from the ECU. The IGT-T signal is a pulse. The BR/Y (brown with yellow stripe) wire carries the ignition select signal (IGS-T) from the ECU. The IGS-T signal is a pulse. The L/R (blue with red stripe) wire carries the ignition feedback signal (IGF-T) back to the ECU. The IGF-T signal is a pulse (will not be addressed further here). The Y/L (yellow with blue stripe) wire carries a signal to the tachometer and check connector (not discussed further here). There is one ignition timing signal but there are two trailing coils. The ignition select signal tells the igniter which coil the ignition timing signal is for (see RX-7 ignition system for source of information). When the IGS-T signal switches from low to high, trailing coil 1 (for rotor 1) should be fired. When the IGS-T signal switches from high to low, trailing coil 2 (for rotor 2) should be fired.

If you have replaced your trailing coil, you may want to check the ground connections between your engine, body, and negative battery terminal. This will usually solve the problems you are describing, as well as others that may not be fully apparent.

The standard rotary engine is powered by three principal moving parts: two triangular-shaped rotors and a crankshaft. There are also 3-rotor and even a 4 rotor variant known respectively as the 2.0 liter 20B and the 2.6 liter 26B.

first do a fuel pressure test also check fuel filter, fuel pressure regulator , injectors primary and secondary.look for external leaks specially the notorious fuel line under the intake manifold. and also if u have a good quality fuel.

The injectors in them are known to drip after you turn off the engine, after its been running for a short period. Pull the fuel pump relay, crank the engine for a bit and it should clear the flood. Or buy new injectors.

In stock form, the turbo supra was faster than the fd rx7. The 93-95 rx7 are quicker in the quarter mile. My 1994 rx7 is highly modified and runs 10 second quarter mile times- quicker than any ferarri or lambo/ porsche.
