Bad news for the 12A (i think)

Well I started the car up today and it dropped oil pressure to 20 pounds and oil was spraying out from under the beehive. The motor is prob not hurt, but I have finally came to the decision that I want a Turbo first gen, I was thinking of doing a turbo II swap and i have been searching. but do you think i would be better off just buying another 1st gen that has a swap already or is my car gonna be down for a year. This is not my daily driver and I have time to work on it a good bit, but is it something that still takes forever. Just letting everyone know that my baby is down and it hurts not to be able to drive her.

Always cheaper to buy someone elses done project. Beehive removal is not that difficult.

its always fun to build your own turbo project car, so you can build it exactly the way you want it.... but, if its your daily driver , plan on borrowing sombodys car, because its going to take a while

Well, this is how I would approach it. If you are serious about turboing your 1st gen then you need to decide which powerplant you want to go with,12at or 13bt?
Once you answer that question then I would start gathering up parts "After" you do a ton of research.

In the meantime, replace the O'rings on the beehive and continue to drive her so you don't go thru withdrawls. Or it would be a good time to upgrade to the FMOC.

Yeah, no ****, just fix the oil cooler O-rings already, it takes a hell of a lot less time than farting around throwing a different engine in and making it all work. Most people who go down that road end up selling their car for pennies as a half-completed half-assed project.

Every one making good points too. I planed on fixing the o rings for right now. I want to go with a 13bt and i have been researching a ton already and theres even more ahead. Hopefully nothing happened to the motor when it dropped oil pressure though.

You would of had to run it out of oil to really do any damage. You have made the 1st step in deciding which motor. Now, do the homework on how you want the fuel to be. Carb'd or injected then do more homework and round up basic parts. Then start working on finding a motor,etc... Do all of the basic stuff first that way when you do the transplant it won't be down as long.

I cannot find it, be I recall reading years ago about someone who was driving her RX-7 and the low oil level light came on. She stopped at every gas station for something like 50 miles and put a quart of oil in at every one.

The drain plug had fallen out, so she basically drove for an hour or two with no oil. After she got home, the car recieved a new drain plug and four quarts of oil and lived for a very long time.



Rotaries are TOUGH little buggers.

peejay that has to be an urban myth or something. Weve had guys blow an oil cooler line and fry their motors, even running synthetic oil. It does make for a cool story

cpa7man, you had the wrong post quoted

But we all know what you were refeering to. And yes it sounds like a Urban Myth.

The only time i've experienced complete oil pressure loss was in a piston car that I had put slick 50 in. The light came on for oil and I drove it home approx 4 blocks with zero pressure. The way I know it had zero pressure is because when I tore the oil pan off the oil pump shaft had spun. I removed the main caps and rods and inspected, they still looked like new. Car only had about 45k on it. I put in another oil rod and oil, started it up and it ran perfectly. The car finally retired at around 135k when someone broadsided me at 55mph.

I remember reading the post that peejay is referring to. Hard to believe it's really true, I was thinking that maybe the plug was just loose the whole time she was driving it and then fell out as she pulled into the driveway. lol.

And as for Slick50? I tried that out in my Dad's '79 RX7 when he had one about 18 years ago. Right after I added it, she started smoking really bad. I even changed the oil about a week later, but she never really got over it. Haven't tried it since, and never will (although I will admit the very high possibility of pure coincidence).

That sure was a fun car though, and was my first experience with a rotory. I saw it sitting in a used car lot and talked my Dad into checking it out. He was pushing 50, but my mom had recently gone off the deep end and divorced him, so he needed something as a pick-me-up. Anyway, they wanted 3k for it. We took it for a drive and it barely even ran so I popped the hood and (not knowing anything about these cars) I got lucky and spotted a coil wire that was not connected to the dizzy. So I plugged that in and she ran like a raped ape! I unplugged it again before we returned to the lot, and told the guy it had issues and left him our number. He called a couple hours later and said that they didn't know enough about these cars to figure it out, so asked us to make an offer. Gave him a grand for it, plugged the wire back in, and laid rubber as we left the car lot.

Sorry to run off track like that, but I haven't thought about that car in years and one thought sort of led to another. lol...

Well everyone seems to think everything is fine( motor wise), but i replaced the rings today after work and now it is really really hard to get started, it never did that before, but it could just be flooded or something, who knows, it revved strong though when i finally got it started. I will have to check it out later.

In support of Peejay, some (LOTS) years ago in Australia, at a car event there was a 4 cylinder a V8 and a rotary mounted seperately on stands, no oil, no coolant just fuel, they started them and ran them all at 1500 rpm until they blew, the 12a took 97 minutes and was glowing red.....the boingers were blown in 5 to 10 minutes.
