86-87 Sport model dont have LSD available, not even an option. P/S was an option in 86 on the sport, standard in 87

rxspeed87

you sure about that?
most everyone I know with the sport has talked about how only one wheel spins
I know if I jack the car up and spin the one wheel that the other wheel will spin in a different direction and if I burn the tirns my rear pulls hard to the right and I only leave one tire mark

worn out maybe but I doubt it is that

My '86 Sport had the 4.1 open diff. No sunroof, no PS, no PDL, no PW, no A/C. It did have the big brakes, TII suspension parts, small aero bits, and aluminum hood. As I recall from the brochures, in '87 the sport package could be had on other models, which is why there might be '87 Sports with LSD. Many people who wanted a pure sports model may not have wanted the sunroof, and if you could only get the LSD with sunroof (typical of Mazda option packages) then there was no recourse but to have the open diff.

The NADA book lists an '87 Sport, but not the '86. But my '86 Mazda brochure shows the Sport and the Road & Track spread on the intro of the FC at Seattle International Raceway in late '85 told how a Sport model lapped the track a couple seconds faster than the GXL they had AND the 944 they had.

Here is a link to the options pages of the 88 and 90 RX-7 brochures:

thank you oh so much evil!
you've saved the day again.

Evil Aviator

Well, it at least helps for those years of US models. Please let me know if you find similar brochures for other years or regional models. It's always nice to have an idea what to look for at the salvage yard.

Despite what several websites claim, only the automatic 'verts and 91 manual and automatic vert had the 3.9 rear end according to the factory service manual.

The 88 'vert manual transmission has the 4.1 rear end.

Icemark

You need to update your information Brandon... It is not correct.

Note the missing comment about LSD in the sport description, but found in the GXL description.


Furthermore note the factory window sticker:

Ok I have a series5 GXl, which I just learned tonight . Anyway it does have LSD since it pulls damn hard when I let one wheel slip. So yes, they were options and yes, I just contacted the original owner and he said that he had it on the car. Just another damn thing to change when the winter ends

RX7boy

umm so the 88 GXL had an LSD and the 89 didnt?

RarestRX

Yo,


I've got Dak's 1989 GTUs window sticker. Looks like the only options on the GTUs was:


A8 Air Conditioning $859
K3 Plush Floor Mats $59


How's that? *grin*

Air Conditioning? Are you serious?
I used to respect your car *grin* <---or is that copyrighted ;-)

just kiddin.

I'm pretty sure that it had the 3.909. It's too darn slow off the line to have the 4.10.

The 88 brochure lists the following for the convertible:

Manual 5-Speed
1) 3.475
2) 2.002
3) 1.366
4) 1.000
5) 0.711
Reverse) 3.493
Final) 3.909

Automatic 4-Speed
Not Available

I guess that the only way to tell for sure is to check rpm vs speed. If you still have the stock-sized tires, then at 4,000rpm in 3rd gear you should see 55mph with the 3.909 rear, or 52mph with the 4.10 rear. It's not much difference really.

BTW, thanks for the pic of the 87's. I've been looking for documentation on the "Luxury" model which several people have been telling me doesn't exist.

Icemark

I'll check in the next day or two.

thats weird, i took the stereo out of my 86 and it was a Clarion 120watt stereo, weird, oh well Only some sport models came with LSD

ChrisV

While it's missing in the advertisement's description, that description (and the window sticker) only lists what's standard, not what's optional. the window sticker especially won't list options not installed. it is still possible for an '87 Sport (which was a package available on other models) to have an LSD, if it came with other option packages.

And the thing I'm curious about: the GTU had the big brakes (vented at all 4 corners, 4 piston Aluminum calipers with raised MAZDA text) like the Sport and Turbo in '88, but not in '89 (where that was reserved for the GTUs?)? A girl I was seeing back in '93 was looking wistfully at some 944 calipers at an autocross and wished her GTU had big MAZDA text like the PORSCHE text on the 944. I showed here my '86 brakes and we wondered why her GTU didn't have them (she had bought the car new, but I do believe it was an '89).

Did we get this figured out on the convertible or does Long or Yamaguchi have to be consulted. I thought they all had 3.90 rear ends to compensate for the weight/mileage penalties?

Icemark

That is correct. I have generally seen the 87 Sports W/ sunroof to have the LSD option. It was not however a standard feature found on all Sports as some people have posted.

That is correct. The GTU became the base or SE model in 89-90, with only the single piston brakes. However the 88 GTU was basically a little heavier Sport with a few more standard features (like better/upgraded carpeting and more sound proofing and power mirrors standard) from the GXL

tmak26b

88 GTU have big brakes it has the word "mazda" on it. 89-90 GTU are base models, they have small brakes, but have 5 lugs. 89-90 GXL DON'T have LSD standard or as an option. Check my website www.geocities.com/tmak13b and look for the sales brochure. THE ONLY NA WITH LSD on the series V is the GTUs, which had the 4.3 gearing, you can check the shop manual if you doubt me

And once again, NO SPORT DON'T HAVE LSD!!!!!!

Icemark

Okay I confirmed it today on my 88 'vert,

rear end gearing on the 88 vert is 3.909, AND top gear is .711 rather than the .687 found on all the other M type (non-turbo) FC transmissions.

The 88 factory shop manual is incorrect listing the rear end as 4.1.

My 1991 Coupe has:
Power locks, windows, mirrors, seatbelts
Rear defroster
1 piston calipers
Cloth Interior
Factory alarm

Hope this helps
