Amazing Miata Open Diff

[miata619drifter]

...or more accurately, suspension. check out this link.

"...an open diff Miata will also leave two black marks if you dump the clutch and peal out in a strait line."

i dont know if this is any help for drifting (turns vs. straight line) but i just found it interesting that an open diff miata isnt a "one-leg wonder" when you dump the clutch and peel out.

always carry a fire extinguisher! if i had one with me 2 years ago, my last miata wouldn't be sitting in a junkyard somewhere all charred up.

so much misinformation on that site...

"+ Miata housing with minor grinding of the interior of the housing (the 1989-91 RX7 is a viscous)."

this is absolute *Censored**Censored**Censored**Censored**Censored**Censored**Censored**Censored*

does that diff swap not work?

[Simon-AE86]

rx7 diffs are NOT vicious diff's

none of them ever were... FD is torsen, FC is clutch pack.

[miata619drifter]

i heard that before 1989 they were clutch type limited slips.

can any RX-7 experts help me out here?

[Simon-AE86]

i know my rx7's ive owned 2 of them....

1986 - 89 is SERIES 4 rx7, they come with both OPEN and CLUTCH LSD's

89-91 is SERIES 5 RX7, they come with CLUTCH pack LSD's ONLY (no open diffs available) all were turbos

all were turbo? this site says different...

"Year-to-Year Changes

1990 Mazda RX-7: GTU, GTU S, and GXL model designations were abandoned for 1991, leaving Mazda's rotary-engined sports car with a single trim level. The slow-selling 2+2 coupe was dropped, too, leaving only the 2-passenger hatchback coupe and convertible. Only the coupe was available in Turbo form. Mazda's option list dwindled, as accessories were grouped into two packages. Air conditioning was standard on all models."

RX-7.com says different about the limited slip types too...

check it out...

"In the '86-88 L.S.D. equipped models, Mazda used a standard 2-way mechanical L.S.D. and then switched to a viscous-style differential for the '89-91 L.S.D. equipped models."

only the coupe?

please explain what a coupe RX7 is as i wasnt aware that they came in sedan as well

seriously now, in japan and every other market in the world, the series 4 was available in non turbo and turbo trims

the series 5 however was turbo only.

[miata619drifter]

its talking about coupe vs. convertible, not coupe vs. sedan

[miata619drifter]

how weird, this place is selling Series 5 RX-7 motors that are non-turbo (there is a 1990 and a 1991 listed)

[miata619drifter]

this is soooo weird, this place is selling 89-91 non-turbo RX-7 motors too.
