Hey now... this is exactly what I'm talking about... 3rd-genners looking down on 1st-genners because we started out with only 100-135hp and 1st-genners characterizing all 3rd-genners as arrogant snobs.

Meanwhile I saw a 3rd-gen at the track today who was talking about his PFS programmable computer and said he was running 20psi (on twins!) and he was shooting for high 12's and he ran a mid-14, which a breathed-on 1st-gen could easily get.

RX7-2JOCK

I'm not putting anything down.......When I said "SAD" I meant it as it was sad that nobody here is helping me....Thats it......So don't put words in my mouth dude.....I like all Rx7s......nobody here is being a snob.........So chill the **** out !!!

Max7

care to explain this one?

RX7-2JOCK

Cause I can easily find info on the 3rd gen.....Thats it....Damn you 1st gen guys need to chill......If I new I was getting grilled for a simple post, I wouldn't have posted in the 1st gen section........I posted this thread to get some 1st gen info.....I didn't get it untill Montrealer hooked me up.....Only one person that owns a 1st gen that helped me...... thanks....I don't need to explain anything more to you dude, your "SAD" :p

Max7

Well I can get you a ton of info on modified 1st Gen, which is what most of us have, but stock info is quite rare to me.
And expecting info at the snap of your fingers, it takes time for all the first genners to come thru and view the posts, a few hours doesn't cut it.
ok, now we can all go back to our normal lives.

Oh and the

......Only one person that owns a 1st gen that helped me......

your first post stated.....

........I know its powered by a 12a and thats it......

And I posted

...I can't think of any reference sites, but 84-85 had an option for the FI 13B 135HP....

so I wasn't helping was I? I was just a rock in the corner?

Not to start anything, but you need to watch what you say

peejay

I'm chilled, dude... looking back though you waited 3 whole hours before complainging that nobody was helping you out.

Some of us have LIVES, you know... I'd be more than happy to go over all of the different driveline, body, emissions, suspension, and equipment changes over the years from '78 to '85 (seemingly every year was different from the last in some significant way, except possibly '85). I could also point you to several very detailed websites, which are actually how I came to learn about them in the first place. But I am not able to connect very often, and today I spent a good part of the day at the dragstrip enjoying my car.

OTOH I can't find very much info on 2nd-gens or 3rd-gens... they aren't as prevalent in racing as 1st-gens because they're still so expensive, and the EFI systems are a hindrance when trying to work within the rules. "Chipping" isn't allowed but carb tuning is... which would you rather have? Also turbo engines are usually banned... I saw somewhere an FD running in SCCA road racing, but the twin turbo engine wasn't allowed, instead it was running a 13B peripheral port and a big fat Weber on top... Plus 13Bs and/or EFI are usually given a weight penalty... and FCs and FDs aren't exactly light either... and (IMO) the 1st-gen suspension is superior for road racing because it's simpler and less complex and it works and it's simpler. (Simple is always better!)

gamble302

you mean you're sad?

abeomid

ok people, please not ditch the 13B engine with EFI, bunch of us 1st gen owners have that on our car which is superior to any 13b engine that was there b4 it and came on after it b/c of the reliablity.

so let's not bad mouth the 84-85 13B EG-EFI engine,

thanks.

One more link that might help.

RX7-2JOCK, Just FYI, a lot of 3rd gen guys tend to look down on the owners of the previous generations. We get a lot of **** from other people that don't know about rx-7's as well. I think thats why some of us seem to be a little defensive about our cars.
Personally I love all rotary powered vehicles. I will own a third gen to complete my collection of 7's within a few months. Allthough the 2nd(T2) and 3rd gens out perform the 1st in almost every way, I would never give up my first gen. It is very fun to drive. It's extremely light and nimble. I have more fun in it than my T2. It is heavily modified and more reliable than my stock T2 and a whole lot more reliable than any 3rd gen I've ever been around.


Peejay, This is in no way a flame, but if you modify a 1st gen to handle as well or better than a stock 3rd gen on a road course it will not be a simple set up. Believe me. Our EP car has a very complex suspension set up thats worth thousands of dollars alone and it probably handle as well as a stock third gen.
the 3rd gen suspension set up is very nice. IRS is much more desirable than a live axle on a road course.

Hey, 3rd gen....Before there was the net, there were books...
Almost like the net, because you have to know how to read, but unlike the net, it's also important that you know how to spell and write.

Look up Mr. Matras book, Sports Car Color History, Mazda RX-7. It will give you a year by year discussion of the Seven's history. You'll note that first gens have the most racing victories of the 3 generations, and that they have the most rally successes. In fact, there's a 1st gen in Pro Rally that consistantly still places so high that they're changing the rules in order to outlaw it....i.e., no cars need enter over 20 years old!?!?!?

Go back through the Forum Archives and you'll see that the '84/'85 GSL-SE was one of the most desired vehicles among Sports Car buffs as it was about the only true sports car being sold that hadn't become an overblown, fat, thruway cruiser. To this day in Drags, SCCA Roadracing, and Rallies, it's the 1st gens leading the way....Sure the little buggers have their faults, but the postives are way more...

Stick around....Read some of our stuff....Try some of our links....Read a bit of history....If you get the opportunity, stop by the 'ol corncrib. I'll be glad to recite the birth and evolution of the Seven. I'll even let you drive my GSL-SE...It won't take long for you to come to the conclusion that a 1st gen provides the most car-fun per pound and dollar than just about anything on the road imported or domestic. Simple, light, strong, and unique. I'll tell yuh pardner....We run some pretty nasty little hosses, and it really isn't wise to point and spit on John Wayne's gunbelt!

A good tug on the Stetson, and a flash of the badge...

Getcha some backgroud info on the rotary here:

http://members.home.com/sofronov/Cars/Mazda/Rotary.html

Tis full of nice comparisons between boingers and spinners, as well as pictures of porting and what not.

1st gens are light weight, compared to most cars of it's time. They're even lighter than 2nd gens. Most models had a 4 barrel, down draft carburetor on a 12A enigne. The 84-85 GSL-SE model had the fuel injected 13B engine.

There are four main models, as well as two very sought after models.

S, GS, GSL, and GSL-SE are the main models, GSL-SE only being produced in 1984 and 1985.

The sought after models are the 1983 Limited Edition and the 1979 (Or was it 1980???) LS (Stands for Leather Sport.) only 3000 LS models are produced and they had all options and black leather interior. They were all painted black. The 1983 LE had 14 inch BBS type mesh wheels and they were all painted an olive green color.

Basic rundown is as follows:

Series 1 - (1979 and 1980):
First run, Only S and GS models available. Primitive Thermal Reactor for pollution control. 1979 had a crappy points style ignition system. 1980 had a basic electronic type of ignition system. Easily distinguished by the seperated surface mounted tail lights. Bumper also looks different and trim is thinner.

Series 2 - (1981 - 1983):
Major restyling of the exterior. Bumpers look more integrated with the car, trim enhances that effect. Nose was re-styled. Tail lights were recessed and look flush with the surface of the car. They appear to cover the entire rear of the car. Storage compartments were added behind the seats. Catalytic converters became the emissions control, replacing the thermal reactor. Ignition system was made a little better. GSL model was introduced with rear disc brakes and posi-traction (Limited Slip) Differential. 1983 was the first year to have non replacable u-joints in the drive shaft and crappy water-oil cooler under the oil filter.

Series 3 - (1984-1985):
Interior restyling, mainly of the dash. Small vent holes were added to the lower front of the nose. GSL-SE model was introduced. GSL-SE had some rear suspension changes to aid in oversteering and handling, in addition to the Fuel Injected 13B engine and 14 inch wheels with new bolt pattern. Larger disc brakes were added as well.

I think that's it on the basic rundown.

My hands hurt. Oh wow. I learned all that and more (rotary engine workings, 2nd gen, 3rd gen stuff, Boinger stuff, carb stuff, other car stuff) all within the course of a year. I dunno if I should be proud or ashamed because I have no life and dedicate myself to these cars.

Where were the RX-7 trivia games?

Here is a lot of good numbers on this like I think you can use.

Thanks for all the info guys and the links..........And this is not, I repeat not a battle between 1st gen and 3rd gen......I've gotten a lot of info from your helpful sites and wisdom thanks again.....You can delete this thread now moderaters

peejay

Primitive, hell! The durn thing WORKS! I was getting 2-3ppm HCs when I had one.

White84SE

Sheesh... Max7 is right... you can't come in here, lay a question down, and expect 20 replies in 10 minutes... you gotta understand.. most of us first-gen guys tend to spend time out in the garage working on our cars... while the bulk of the 3rd-gend ownders I've seen tend to send their cars to garages for work.. hence they have more free time to BS on the 'net...

He he

Come on... flame me.. I know you want to...
