i am planning to buy a gen2 (1987) rx7... there are one rx7 that i found today... the lady ( owner) did not help anything about her car.... i want to test the car... as i am there.



as far as i know

- sat on the road for 6 years
- last time it was running....
- no rust


thats all.


i assume

- very low km
- body should be very excellent as well.

i thought why not take that car.... ( advantage hers)


my problem is

- i am very ingorant about rotary... actually i know a very little... 12b and 13b.... and common problem ( overheat for mostly turbo model)


so i need advices from expert like you

i assume i will do first

- a hose and a tank with fresh gas... 6 years old gas probably wont do.... right guys?

replace old gas with fresh gas.

- battery
- alternator ( at driver side, top of rotary engine... right?)

above; batter jumper should do job.

- starter ( at driver side, bottom of rotary engine... right?)

push the car ( i will get battery for back up... but i am not sure what kind battery... i will find out later anyway)


is there anything missing wire, ignitor problem, etc? any suggestions?


thank you very much.

sat for six years straight? dude apex seals are gonna be stuck. try starting it and see what happens before you buy it or plan on rebuilding it if you get it dirt cheap... yeah that gas is done too

High probability it may have a stuck seal if it was sitting for that long, let alone other components (ie. stuck brake calipers). Also check the electrical system, if it's been sitting for 6 years, you have no idea what presents mother nature has given that car.

er..yeah the KM might be low, but most Vancouver cars have pretty high milage

Yes, you'll definitely want to get some fresh gas in there, as well as a battery. If you do get the engine to turn over make sure to do a compression check!!!! THIS IS KEY

very top of the engine, you can't miss it.

Bottom driver's side, yes. However this shouldn't be blown (not unless she's specifically told you).

Above all else, make sure you know what you're getting into with these cars, read the FAQ, as well as the archives. Both of those are very good sources of information, especially to new people. That's a very general run-down, but i hope it helps.

Car will need 1-2 grand in replacement parts to be a reliable daily driver if it hasn't run in 6 years. Every belt, hydraulic cylinder, hose, coolant cap, vacuum hose, tire, and brake caliper will need to be inspected or likely replaced. Change all fluids, flush coolant. It will likely need a new gas tank and pump.

And you'd be damn lucky if the engine was any count, not carbon locked or have stuck/rusty seals. I just took apart an 80k mile FC that sat since 2001 and it had 2 severely stuck side and corner seals, and slight rust inside, but I was able to save and rebuilt it. Oh, and it requires a complete fuel system overhaul including replacement of the rusted gas tank/fuel pump/sending unit/fuel filter/injectors.

whoa.. lots than what i expect.


i am very appreicated.



first post,

what is "apex seals" exactly? is that something relate to inside of rotary?



second post.

i agreed if only it was outside for many years...


i am not too sure... she said 6 years so i assume under 120,000 km.... yes you are right... there are lots of km cars at vancouver due to large space.


this might be sound so stupid... is progress of engine compression similar to pistion engine? i mean 12b has 4 spark plugs. ( 2 spark plus each rotary)... what is normal compression level? 160? similar to pistion engine?


i am trying to fin FAQS here but i can't find anywhere... archive is too general and mostly modified... i am trying to research rx7's engine ( i careless about body, etc because similar to other cars ;d)


thrid post,

eeks it sounds bitch job... but of course i know i will need to upgrade/update all old parts or whatever.



arlight thank you for all important information... i am really appreicated.... but what if its turbo model? ( i assume not...)

i will let you guys know if i will take or not ( depend on my own time and work requirement)

So uh, is english not your first language?

Apex seals are the main internal seals of the rotary engine that generate compression. They are the main failure point for rotaries, and when the engines sit without being rotated every few weeks, these seals tend to lock in place. From there on out, the engine will not make full compression, or it may lock up altogether.

Rotary engines make 120-125psi compression when new/perfect. Most used rotaries make 90-100psi compression, which is acceptable, but getting weak. Less than 90psi is where many of these old engines will be, and they could let go any time. It also results in hard starting when hot, referred to as flooding. This issue requires a rebuild to resolve.
