Ok orginally I was gonna purchase this car.

http://batonrouge.craigslist.org/cto/1568115633.html

It needs a new fuel system, minor body work and repaint, and interior work but it has a new motor. O and its an auto that i would want to convert (can get parts cheap but its still something else i would have to do.

But today I just found this one

http://batonrouge.craigslist.org/cto/1582933044.html

It appears to have most all the after market parts that I would want allready included/installed and looks to be in better condition

So should I go with A. or B. or If the 85 is a carb'd 12a should I buy both and swap the new engine in this body?

Im really looking for the most economical route and I feel spending more now will help me save later.

Any thoughts on trouble swapping the 82 into the 85?

 

OK after checking wikipedia it is confirmed that it is a 13b and at some time was fuel injected. So will that racingbeat intake manifold mount to the 12a or was the intake maniforl style changed between the 12a and 13b?

The issue is i see several 12a's for sale and 0 13b's and i wouldnt want to buy a car that i couldnt get an engine for.

 

I'd say if you wanna get to know the car, then pick up the $400 one and rip it apart and do your own customization. However 1000 is a good deal for the other one too.

 

If it wasnt for the body work I would def get the first one and call it a day BUT knowing that I could easily put over $1.5k in paint work in a $400 car is kind of a turn off when the other option has a good body.

If the motor swap is straight forward i think i may just buy both?

Anybody know if the manifold is the same?

Thanks for the input.

 

The only model of the first gen RX-7 that came with a 13B was the GSL-SE. all the others such as that GS had a carb'd 12A.

It smells slightly fishy about it to be quite honest, considering just the suspension and rack n pinion conversion, that's well over $1,000 worth of parts and then the full carb setup is IIRC close to $800. I wouldn't hesitate to go out and at least look at the car but I wouldn't expect anything to be completely true either.

Not likely, as far as I know the only 12A stuff that can be mounted onto a 13B is onto the old school 4-port 13Bs and those require an adaptor plate.
As far as 12A to 13B swaps, those are pretty straight forward and there are probably a few writeups floating around with detailed lists of what is to be done.

 

I agree with Darren...$1k is a pretty sweet deal unless it's beat to $#!%. Even as a parts car you'd get your money back.....I'll even pony up $100 for the rack & Pinion lol!
Seriously, does the GSL run (blue one)? Even at $400 the brown one seems like a money pit....undiagnosed fuel problem (could be simple....could just be the tip of an iceberg), and then you've still gotta swap out the automatic, and then dump money into body work....that'll just get you a "decent" car, then if you're gunna start mods.......just seems like a lot of work for a not-very-special-car.
Take it for what it's worth, but that my opinion and it's your money.

Thanks for the responses. I was just planning on redoing the whole fuel system but it does sound to be a money bit.

Unfortunatly I cannot have a parts car sitting around if i did get both id gut one over a weekend and haul of the carcass a few days later as my HOA does not allow parts cars and the such.

Also you said the early 13b was compatable with the 12a's. What constitutes as a "early" 13b? Wasn't the 84-85 13b's the first to see action?

Thanks again for the help everyone!

EDIT: ok i see that the 13b was used in other things besides the rx7 in prior years. This would be very economical assuiming the intake and exhaust manifolds matched if not then...

 

Actually I would be going from the 13b to the 12a which i guess is a downgrade but the 12a is known to work. I guess it would still be as straight forward just backwards.

Thanks

 

I don't see 13B mentioned in either ad so put that out of your mind. The blue one is a steal for the upgrades, the tan one is a steal for the rebuilt engine. I would buy the blue one first and check out the engine, if it's toast buy the 82 for the engine. Please do not scrap the 82. If it's mostly rust free someone will take the body for $100-200. If nothing else, pull the engine out of the 82, park the 85 till the 82 sells so your HOA doesn't get a cob up it's ***.

 

ok i was under the assumtion that the 84-85s came with the 13b efi.

Well thats good news, I guess I have some withdraws to make.

Thanks again with your help everyone.

 

in the us we had 4 models.

the S, GS, GSL all were 12A carburator.

only the GSL-SE came with the 13B efi engine.

YOU should look at the 84 first, its nicer.
