Second.Gen.Gone.

Hello everyone i am new to this forum so ill give you the basics. ive got an 1987 rx-7 with a 13B engine. when i got the car i was told the electrical had been jerry rigged to do something(im un-aware of what.) but some fuses under the hood had been taken out. and that was 10 years ago so it hasnt run in over 10 years. after looking over the engine i found 4 spark plugs. 2 on top with blue boots and two under those with black boots. and one of the black boots had been cut off from the line. would this prevent the engine from running? after i get a battery and do a basic fluid tune up i will replace the wire and boot. do you guys think it will run?

any advice is greatly appreciated!

Well, I'm not sure why you're trying to run the engine with one spark plug not hooked up. The bottom ones happen to be the leading plugs, which do 90% of the work. So, yeah, it will have a lot of trouble running at all. Replace fluids, spark plugs, fuel filter, fuel sock and whatever hoses have degraded over the years, and it may run.

Read the FAQs on the main page and read this ... This should help get you started http://www.aaroncake.net/rx-7/unstore.htm

Where in Michigan? Stop by the regional sections (Midwest) and you will get more "localized" help, possibly even somebody willing to stop by in person.

Good luck.

Thank you no love for pistons for that link. it was very helpful!. i will be doing a complete system flush, new wires and fuses before i try starting it. being only 15 gives me plenty of time to work on her. im in no hurry and i will keep you guys posted!

im on the eastern side of the state close to Detroit. but thanks anyway!

after 10 years of the engine not moving at all the engine may be seized or rusted on the inside due to fluids just sitting there for so long or the seals can even be done for since there hasn't been oil lubricating them in forever.

Second.Gen.Gone.

so i should think about rebuilding before i waste my time on the basic tune up?

Kentetsu

Start by grabbing the front pulley and seeing if the motor will turn over by hand (make sure tranny is in nuetral). Post back with results.

No you should check everything out to make sure none of that stuff has happened before you decide you need a rebuild, also once or if you do get it running a compression test will tell you for sure.

Second.Gen.Gone.

Well i pulled on the engine pulley and it moves but then i hit the compression cycle? and its difficult to pull any further. but it will rock back and forth nicely. i also have some electrical questions. ive taken pictures of my messed up main fuse box. and all the fuse connectors that are not connected to anything. so if someone could tell me if they are supposed to be connected to anything that would be great.

thanks.

Here are some more. a few from the interior.

the engine should roll over rather freely with a 19mm socket on the front pulley and a Rachet.
You say you are hitting Compression???.NO..it should just be a little "blip' then roll freely again.
I would research a little further about engine that have not been running for a long length of time

The car has been sitting for ten years? wow umm o.k
well your 15 y/o right so no money but i assume your parents will trade you working around the house for some money.
realisticly the engine will have to be rebuilt. that doesnt necesarily mean new rotors ect. but that the seals and gaskets have to be changed.
find a local rotary shop they can check the engine out and see whats salvageable. like the rotor housings, rotors, eccentric shaft, flywheel, oil pump, ect. since the engine already has to come apart anyway.
since the transmission and diff are pretty much sealed i would just change the oils out, probably change the clutch too.
post some more pics of the car especially the engine bay.
heres the 86-88 manual

rebuild cost isnt that much just the labor and machining(if its needed though i recommend it)

Second.Gen.Gone.

Im hoping to have a rebuild or at least tear down as my last resort. Not only because of the labor and all but because of the fact there is not a shop nearby that specializes in rotary engines. on average if all im needing to replace is apex seals. how much would that run me. and ill get some engine bay pictures up soon.

thanks!

if you want the engine to last past its first fireup your going to have to teardown and rebuild.
no engine in the history of ever has been sitting for ten years and didnt need a rebuild .
first thing that you should do is take the engine out. then worry about updating the electrical while the engine is out.
look around in the forum for someone close to help you out or if they can recommend a shop.
these cars arn't hard to work on and with enough knowhow and confidence any one can rebuild these engines.

heres what i charge for a 6 port n/a rebuild
8 oil o rings $85
1 side seal sping set $24
1 corner seal spring set $24
1 corner seal rubber set $26
1 OEM mazda apex seal set $280
2 OEM mazda apex seal spings set $60
1 set of VIVO racing housing gasket $90
2 OEM mazda retainers $20
2 stationary gear bearings $45
1 rear roller W retainer $22
1 rotor housing restoration $140
6 1/4 quart quaker state 20 w 50 $20
its around $840 parts & services
and $400 labor, installed, and started.
now lets do some math you have $1200 thats $100 a month thats $25 a week or $200 a month thats $50 a week
i do credit but i keep the engine until the person completely pays. most shops like mine will keep the engine until you finish paying, and this way you'll have an engine thats as good as 0miles installed and ready to go.

Thanks for all the information on the rebuild. but at that price would it really be worth it? and like ive said before there isnt any rotary specialists anywhere near me. so i would have to ship it somewhere and then reinstall it myself.

oh man ive seen worse a little work here and there but the outer parts are salvageable, and rebuildable if needed. i would guess the insides might be a bit iffy but savable still.

yes its worth it. the estimate i gave you is to have the engine brand new 0 miles, and made for durability not racing. the rebuild is the most expensive part after that its a little a little there. and by the looks of it you shouldt try to start the engine at all.

banzai racing is the best place to go near you, even if it is far you can have the car towed or trailered there.
heres their contact (574) 594-2035 sales@Banzai-Racing.com tech@Banzai-Racing.com

though i hear they dont regularly answer, but you can get a whole bunch more help from them since they are closer, and im on an island in the caribbean.

Would there be any damage done if i tried to start it without a rebuild?

ive talked it over with my parents and to them it doesnt seems worth it to spend that much money on what was picked up for a scrap car. I would love for the car to stay its absolutely gorgeous looking but towing it somewhere + the cost of the rebuild + the cost to get it home. my parents think it would be better if the nearly 2k was spent on a RUNNING car.

We always answer the phone if it rings during a normal business day. We are not there to pick up the phone at 9pm on a Sunday, but the answering machine is. If anyone calls our shop and does not get a person or the machine that would mean we are on the phone talking with another customer. If you get the machine and do not leave a message, then it is impossible for us to return the call. We always answer every email we receive.

Second.Gen.Gone., the car does not look like a completely lost cause, but it really comes down to your available time and funds. That car is going to need some work.

Your parents are probably right, for $2K you can buy a running 5 speed RX7 GXL, if you want one. This is a base model automatic, sell it for a few hundred to someone that needs a parts car or wants to build an ITS race car.

Second.Gen.Gone.

How much would it cost if i were to bring the car to you and ask you to get it running? just plain and simple. no unnecessary tearing apart.

That is absolutely impossible to quote. No way to tell you everything that could potentially be wrong with the car from the couple of pics you posted. The car has been sitting for 10 years, and someone "rigged" all the fuses for some reason before they parked it. It is not like this was perfectly running car that was stored in a climate controlled environment for 10 years.

I would have to say that even if the engine has compression the entire fuel system needs to be replaced/rebuilt.

Second.Gen.Gone.

ok well thank you for your help. i think im just gonna either find a replacement 13b or just scrap the car for money for a new rx.

Finding a replacement engine is not the solution if you do not even know if this engine is bad. That would just be a lot of work to replace the engine in a chassis that you have no idea what could be wrong electrically.

I can tell you this the car will never start without the intake piping connected to the throttlebody. There is also a good chance the fuel pump is completely seized from sitting in bad gas for 10 years, same holds true for the injectors.
