My point wasn't that it's a waste of time to do this stuff, but that it's a band aid. No Miata engine makes enough outright torque to strip the teeth off the gears in a Miata 5 speeds. People break them with sharp cyclic loads and impact damage. SO, if you use a reasonable clutch, and drive with a little mechanical empathy, it should last MUCH longer with these mods. If you put a 7.25" unsprung ceramic clutch in it, and/or drive it like a retard, you're probably going to break transmissions no matter what you do to them.

^i agree completely. there will always be a week point. if you drive it like an *** hat you can break anything.

i used to mod subarus and people always said the trannys were like glass but i ran about 250 at the wheels on a stock tranny and a friend ran about 350 for almost 90k miles and stripped second gear trying to do a drag launch.

How much would people on here pay for a bulletproof tranny? I mean I bet if you got like 10-20 people to commit Quaife would sell the sets for under 2k a piece probably closer to $1500 and that's only 2 6 speeds for a 500+hp gearset.

Whats your point?
The 02-07 wrx 5 speeds are very fragile. Gears are long, and fd is super tall and engine is very torquey which results in stripping gears past 300whp. My 07 went at 360wtq without a single launch or fast shift. Just eased into the throttle and shaved 3rd clean off.

You make power you break things.
What OP is trying to do is to possibly prevent future breakage by taking precautionary measures.

If I was kaisersoze I'd just get a quaife and call it a day. Lord knows he's already invested buckets of cash into his super sweet msm, I don't see how another 2k or whatever it is, is going to really break his wallet. lol

By "we" I think you mean "you" haha (because no one else in their right mind is going put more than 500 hp in a miata) props either way though.

and hell, it might be able to withstand 800, I just doubt you'd be able to hook up 800...

Hmmm....I just picked up a stock 93 and sometimes I can push the clutch to the floor without it enguaging.....is it most likely do to this line with air in it somewhere?

If it's intermittent, it's probably a dead slave.

Thats what I thought but the PO claims to have replaced the slave?? I was thinking there could be some air in the line bc most of the time it drives fine but a couple times a week so far it's gets iffy. I really have not clue exactly wwhat it could be....do slaves work at times and then just quit then work again??

Some times. If it's a new factory slave, then it could very well be the master. Is fluid disappearing over time?
