Got my first Rotary (not counting my FB that was bought with a blown rotor and never got to fix it and just sold for $100 )

a 1986 FC GX (Canadian Model) Im in CA though lol. Got this baby for $2100, with 66k original miles!!!! Im so stoked!

Here is all the info I was able to gather about the Canadian GX models:

- oem LSD
- power sun roof
- manual windows
- manual locks
- power side mirrows
- no rear wiper
- alum spare
- alum jack
- 5.5L washer
- rack & pinion

its so cherry and I love it.

So of course, I know the stigma of owning a rotary and take great care to check the oil every fill up, and to let it warm up and cool down (possibly to an obssessive, overly paranoid degree).

So here are some questions I have for you guys:

Is there an exhaust available that is CA legal? AKA has a CAT (doesnt necessarily need to be CA legal, just needs a cat). RB's and APEX'i's exhaust all just have "presilencers," are these cats?

Second question is: will Turbo II 4 piston calipers bolt right onto the 4 lug knuckles as log as i get steel braided lines for the 4 pots as well as get my rotors drilled for 4 lug? or will they not even bolt up? I ask this because a friend just straight GAVE me some TII calipers he had laying around.

Last question: So, if there isnt an exhaust made with a cat, if I bought an exhaust and fitted a cat in where the "presilencer" goes, what size cat should I fit to it? Will any universal type cat work as long as it is the same piping diameter? Because I know there is some problem about running a straight bike, or a pipe without enough backpressure, and the butterfly valves for the 6 port NA engines not opening.

and on to the pics!

Hey guys, was wondering if I could get an answer on some of my questions.

Search turned up nothing on the brake conversion, exhaust I pretty much have figured out.

Is the brake conversion possible?

Icemark

All your questions have been covered quite a few times before, you may wish to use the search function found in the upper right hand corner of the page.

But to make it short, you can replace the brakes and hubs with the 4 piston fronts and vented rears.

And the GX did not come with a LSD. It is the same model as the US spec 86-87 Luxury, 88 SE and 89-90 GTU. Do you have a picture of the Vac line routing sticker on the underside of the hood.

For better response to your questions, you may wish to not post pictures unrelated to the questions you are asking. Pictures to show off your car, should be posting in the appropriate thread. And while am sure you are proud of your new car, when you post pictures as you have done in this thread, people tend to overlook any questions.

Instead for best response; post a question (only after reading the FAQ for FC sticky thread and also searching) with a clear title that represents what you are actually asking. Dumb titles Such as "Help", "New Member" or the like, often get passed by and not read by forum members.

And finally, bumps are forbidden in this section of the board

I will keep from posting pictures next time, but they were posted because of a lack of an Introduction forum from what I saw.

Search turned up nothing in terms of fitting 4 pistons calipers onto 4 lug steering knuckles, and your response to my post did not answer my question either.

I realize that 4 piston calipers fit on 5 lug hubs if I convert....But will 4 pistons calipers fit onto 4 lug hubs? At this point im just looking for a "yes" or "no."

I've read the FAQ many times. Nothing in there references:

-Catted aftermarket exhausts
-fitting 4 piston calipers to 4 lug hubs

I was up till 2:30am last night using search, there's nothing there.

The GX did come with an LSD. One source of information would be a friend of a friend with another canadian GX model, and the other source of information would be the "hammer-down, dump clutch" method, which has yielded twin streaks consistantly every time.
Unless my spider gears have seized, Im pretty sure it's got an LSD.

Icemark

No, Brake rotor size is different. Heck even the single piston 5 lug rear brakes won't work on a 4 lug non vented rear.

ah, as I suspected. Friend of Friends... and street racer testing.

I can "hammer-down, dump clutch" and get twin streaks of burnt rubber on just about every decent running base/Luxury/SE/GX model made regardless of if it has a LSD or not.

The combination of small tires and a very light model make it remarkably easy to do so. And Despite urban myth, twin streaks means absolutely nothing to do with wiether the car came with a LSD, but rather that you have poor traction.

The only way to actually tell would be to jack the rear end up in the air and turn one wheel. The direction that opposite side wheel moves will tell if you really have a LSD. What direction does yours go???

Icemark, all Canadian FC's came equipped with LSD's, indipendant of trim level.

^^eheheeh WRONG

I have several FC (oh and Im in canada) a few of them are non turbo and - yes - they come with open diffs.

Icemark

I am sure that many owners of Canadian FC's would like to believe that.

edit< actually I am should say, that many owners of FC's would like to believe their car came with a LSD- of course more would be believeing in a falsehood. Very few models (in the grand scheme of the model) actually came with a LSD.

The following Canadian models came with a LSD:
The 86-88 GXL
The 87-91 Turbo
The 88 GS

I muddled my information up between cars... all Canadian 240sx's have VLSD's... not all Canadian RX-7's are LSD equipped. My apologies.

However, given the information he has offered, his car IS LSD equipped either through dealer option or previous owner's upgrade.

Icemark

Dude... how do you figure???

Because his friend had someone tell him???

Or that he can do a two wheel burn out on the street???

Niether have any sort of validity of having a LSD. Again with that mentality there would not be a RX-7 made that didn't come with a LSD.

His only real test would if he jacked the car up, since it is a 86 or early 87, and see if the opposite wheel spins the same direction or the opposite direction.

That is the only test for a Clutch type LSD...well, I guess you could see if there was a tag on the fill bolt for the differential too, but that still would mean anything in the face of a real test.

Actually I think thats wrong also........

But as Icemark said the only real way to tell is by verification of the tag, or head over to FC3S.org and search out the thread "visual differences between open and LSD diffs" and count the number of ribs your has........

Yeah, awesome guys.

Way to censor your own board to show how "right" you always are.

I have nothing against RX7club's forums. When i had my FB, I got NOTHING but quick, KNOWLEDGEABLE, and unbiased help. Those guys are great.

you FC guys have got to SERIOUSLY check yourselves. And I dont even WANT to know how the FD guys act.

Im done with this board. Have fun.
