my first rx7

Well just went and looked at the car , turns out its a 1983 with a 12a and 5 spd tranny , Its black with red interior has no power options in it or sunroof , interior is decent and the body has a few dents and its got a wink thing going on with the headlights but overall I think its something I can work with . The owner said it ran when parked(3yrs ago) but only off of starting fluid . what makes me happy is that its virtually rust free . Hoping its a fuel pump issue but Im soon to find out . going to pickup the car on Friday . I ended up getting it for $200 so Im thinking either way this goes its a score .

What do you guys think would the fuel pump and fuel lines be the first place to look ? The motor looks all original down to the original carb and air cleaner .

I cant wait to start working on it this gonna be the longest 3 days of my life .

Start by doing lots of reading in the 1st gen tech section. Most every problem that you will find with the car, has already been figured out by somebody. The search button will be a great assistance to you as well.

Best of luck.

No, it's not a good car unless you have twice the money you have already saved and are a good mechanic.

Start with draining and changing all the fluids. Oil coolant and fuel now, tranny and diff can wait. Add a can of Seafoam with 5 gal. of fuel. This will help clean out the fuel system if you get it running. Be prepared for lots of smoke once it does get going. Change the fuel filter!! Test the fuel pump for volume and psi. If you can't get it running, most likely the carb needs rebuilt since it has sat and the previous owner had to use starting fluid.

Read the FAQs at the beginning of the 1st gen section and download the FSMs and Carb Manual.

Unless you're an experienced mechanic and have owned a rotary before, paying someone else to work on a 3rd gen, if you can find someone, gets quite expensive. Oh, and don't look to the dealer for help, they're worthless and overpriced. Most of their good rotary mechanics are long gone.

The problems with the car basically stem from a complicated turbo system that practically failed off of the dealers lot, poor heat management and a very dumb speed-density EFI system. To make the car reliable starts with an engine rebuild, replacing the stock ECU with a full standalone, ditching the twin turbo system and replacing all the stock cooling components (intercooler and radiator, etc.).

Got it home tonight after pretty much pulling it out of the bushes , found out it actually would run off of gas( so I was told) but just not from the cars actual fuel tank , the tank was out and full of rust . Claimed it didnt smoke and ran really good but we'll see . The tanks exterior is completely rust free and looks good but the inside is full of rust loose rust chunks . Could I salvage this tank? Or should I look for another ? I know rusty tanks are a common problem with these cars but what would be the more cost friendly route? still very happy with the purchase cant wait to get it running .

Its also got some oldschool after market wheels on it that look pretty cool , I'm thinkin of blacking it out all the way with flat or satin black I mean everything but the tailights and the windows . Ill have to post a pic of the wheels to see if one of you guys can tell me what they are.

the tank can be saved! i just seen this on that show muscle car on spike tv. they had a 3 part, i think it was 3 parts anyways, process they did where they cleaned it and sealed the inside of the tank and it was good as new. it was the tank outta a budget build. in the episode the car had a weird air cleaner with two snorkels on it. sorry i cant remeber anymore but someone should be able to chime in and help

theres a kind of acid you can get that will eat away rust but leave the metal untouched...look that up

also youll want to clean/replace the fuel sock on the pump intake and check that the pump actually works. likely the carb could use a good cleaning as well.

and if you do use that acid to clean the tank make sure you wash it out VERY well afterward.

Im just wondering If I can use the stuff called tank cream thats used on atv tanks . Probably have to use a lot more but I dont see why it wouldnt work. but yes the carb getting cleaned and filter replaced along with testing the pump.

I got my first chance to really check the car out today when i was cleaning all the junk out of it and aside of the dash being cracked all to he!! the interior is nice . I first claim to it being rust free is fading as i start tearing into it . I dont care what it takes Im gonna bring the car back to life

blah. find one that needs mechanical work instead of interior/body work. you will thank yourself dude. interior parts are hard to find and rust is always, ALWAYS worse than it first appears to be.

no way man , I ts only got rust in 2 places thats kinda bad , but the good thing is my body man will be back from Mass. in a week or two . Im not trying to make a show car outta this thing just want to get it running and have a second car slash/toy . I have a practically brand new Dodge ram for daily transportation , so this is just a toy basically . found out the wheels are CS racing (carrol shelby) . Im the kinda person who will take something someone else would trash and bring it back to life . I got a 1982 Honda atc 185s that shoulda been scrapped but I got it running and fixed it up and has ran great for 3 years .

lol i know im doing the same thing with my car....just make sure youre prepared to sink many thousands of dollars into this thing. damn near everything is going to be worn. the suspension, the rubber parts (virtually every suspension bushing and mount bushing should probably be replaced) the brakes the driveshaft U joints etc. this will probably turn into a massive project

i bought mine for 700 bucks and have since put over 3,500 into it, and its still nowhere near back to original condition.

It looks like that stuff has to be painted on , Not sure how that would be possible .

With doing more research the tank kreem stuff int that great , I might try the Red-Koat brand . not sure though , Its gonna be a couple of weeks before I can start spending money on the car . Now I just try to beat dents out and im going to fix the 2 rust spots . Anybody have a driversside tailight for sale?

the Eastwood company sells a kit for restoring gas tanks. It might be the same 3 part kit mentioned earlier.

I used a tank creamer in my HD years ago and still looks perfect inside. It was easy.
