Mazda RX-7

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.

Gaskets and Seals for a rebuildable block plus Labor Runs in the general area of $1300.00. Market research from Rotary Resurrection

It holds two people.

Not sure what exactly the question is, but the front rotor is number 1 and the rear rotor is number 2. The answer would be 0. An Rx-7 has 0 cylinders, and 2 rotors.

If you look on the driver side back by the break pedle you will see the fuse panel

1978-1985 Generation 1 (FB/SA) [Series 1,2 and 3] RX-7s did not come with an LSD.

1986-1991 Generation 2 (FC) [Series 4 and 5] did come with LSDs on the turbo models, they differ between the series. Series 4 had a clutch type LSD, while series 5 had a viscous type.

1992-2002 Generation 3 (FD) [Series 6, 7 and 8] came with LSDs all torsion type.

Yes TRAILING and LEADING...at the auto store they will give one pair of each...make sure you follow instructions on ow to cange plugs in rx7 and make sure you put them back in the order you took them out...It says on the plug box which is trailing and whic is leading

Hitachi built HT-18 Twin Scroll turbocharger capable of operating at 12-14psi max. limited to about 6psi by the stock wastegate.

i believe the smell and low mileage are directly related to you removing the cat. heres why.... 1) Cats are primarily designed to remove harmful NOx gasses from the exhaust stream by heating them up to around 600+ degrees. imaging lighting a match, theres never any smoke until the flame goes out therefore the hotter something is the more complete the combustion is. Cats work on the same principle. so you will have a lot more toxic gases coming out of your exhaust with out a cat which will alter the way the exhaust smells hence it will smell similar to a car wich is over fuelling. 2) due to the above process backpressure is created as a side effect of the NOx scrubbing process which in its most basic form will restrict the flow of gasses out of the exhaust stream. as the engine is having to fight this resistance power and therefore mileage will drop. when removing the cat you are taking away this restriction which will decrease your mileage but increase the power output of the block. given the nature of the RX7, which as standard produces more exhaust gases and get less mileage than the average piston engine the removal of the catylizer is only ever going to aggravate the situation. the only option really without reverting back to the original catalytic converter is to go with a racing Cat -these will scrub the NOx more to reduce the smell but will do next to nothing to increase mileage. i believe bonez make a very good racing cat. hope this helps.
