2 years.

The frontend components are the same. The only difference is the interior and a minor rear chassis change.

ty rx7doc i talk 2 some ppl from rx7club and they did not know so i did not want 2 pull some bolt and find out they did not work and have 2 put them back on.

rotor vs. piston

what is the "minor rear chassis change"?

Lower rear trailing arms mount 20mm lower on the 84/85 than on the 79-83 models.

Yes to increase steering looseness but to increase handling too.

Part of Mazda's fruitless attempts to keep the rear end from snapping out violently mid turn, haha what a joke....
There are some very minor differences in the emissions equipment in the rats nest and on the carb.
Also the 83 has the smaller axles in the rear end.

don't forget the 85 rear end housing is bigger and it has bigger axles.

Basically the things that are different,are different on all 1st gens from those two years.The fact that they are both GSL's doesnt really matter much.

All 84-85's had different interiors from earlier cars.
All 84-85's had bigger rear axles and bearings than earlier cars.(and the rear link thing)
All 84-85's had vented front valences and embelems on the rear deck.

83's were kinda a mutt year for the 1st gen.They stand out by themselves,whereas all other 1st gens share most of their traits with another year model,either before or after....
79-80's are the same,save for some minor changes.
81-82's are vitually identical.
84-85's are also virtually identical.

83 saw the intro of the water oil cooler and bigger radiator,which was later scrapped on the SE and all 86-UP rotaries.They got the bigger front wheel bearings,but not the bigger rear wheel bearings and axles that came in 84.The heater controls were changed,just to be changed again in 84 with the redesign of the interior.The LE and 12AT were the real "big deals" of the 83 model run......just too bad we didnt get the turbo here!

Whats different about the heater controls on 83's? Also, 83's still have the smaller front axle bearings....

steve84GS TII

Im not sure what exactly they changed about the heater controls,just going off what my RX-7 history book says....its been pretty accurate so far.

You right about the front wheel bearings,my bad......

Hmm, actually you might be right about that, the controls themselves are teh same, but the plastic thing that shows hot/cold and which position the ducts are in was different, maybe thats what it refers to....

its cool. i am going 2 get the bolt off a 85 gsl. its killing me that i am about to spend about 1300$ 2 fix the front end and exhaust. i am getting new
B&G Suspension - Springs - Coil - 1.4-Inch Front Drop and 1.4-Inch Rear Drop Sport Springs , a new header"black", new exhaust with a magnaflow tip, four new tires, front and rear struts, new brakes , under dash light kit, under glow kit, front end alignment, a bolt " i dont know the name of it", cd play and a dash kit so it fits right. i think thats all.

1200$ later thinking ur car is going 2 drive right and u can start feeling better , just to find out u need more work priceless.

"83's were kinda a mutt year for the 1st gen."

En garde, varlet!

I LIKE the 83. Seems much lighter and more agile, the paint seems to be best and most durable. Simpler engine bay with more finger room. Smoothest running car I've ever owned.

If I had to have just one 7 (I don't, but I feel morally that I SHOULD just have one) it would be the 83GS. I'd giveup the 85GSL and 85SE first.

The 83 was also my first and best carb'd one that I have owned. It was a GSL. Although the bulk of Fb's that I see in the yards are mainly 83 models which was making me think that maybe because there were so many of them made or that 1st year beehive oil cooler?

bliffle

I'm going to instrument the beehive on my 83. I have a pedestal spacer with 2 gauge spigots and an oil temp gauge that I'll install next time I change oil filter. I've gotta know if I need to install the FMOC I have ready-to-go.

It would be very interesting to know the results.

steve84GS TII

I didnt mean it in a negative way.
Technically,the 83 is a blending of the 81-82 cars and the 84-85 cars....hence,a mutt.
It seems odd that Mazda would start to do things like the oil cooler,LE and J-sepc GTX but stop short of doing the whole update at once,like they did with the 84-85's.The 84-85 revision and intro of the SE was pretty extreme for a 2nd to the last year run,before the FC came out, and was only eclipsed by the 81's major revision over the SA......

Rogue_Wulff

Umm, yeah. You need to have the FMOC in place when you remove the beehive. Without the FMOC to route the oil thru, how would you cool it? Plus, when you remove the beehive, the oil line will no longer have anything to hook to.

As for the high number of '83s in junkyards, prolly is directly related to the beehive oil heater.
My '83 is showing 207K. The engine had been rebuilt/ported, but it still had the beehive when I got it. The oil control seals are not in the best of shape. I have since gone to a FC FMOC, but hate the thought of pulling the engine to rebuild, when it runs so dern strong.

steve84 GS TII Mazda as with any auto maker has to keep adding to cars to keep them selling if you look at sales numbers they are always higher in the begining then as the car gets older you have to do more to make people want to buy, simple mazda brought out the 13b in 84 to show what was to come of the new RX-7 in 86. Mazda had fuel injected Rotaries before that so why wait that long the phrase "What have you done for me lately" the general public always wants more never give them everything in the beginning. Why take a year off between 91 and 93 TO sell off all the old 91's they had the 3rd gen body done before that.
