Everyone knows I am purchasing a 91 tII... I was wondering if the stock lsd is worth it? Or should I just go crazy and just swap it with a helical lsd??? Also as far as maintanence on the Lsd what do I do???

 

depends on what you are trying to do... what are you using the car for???

 

keep fresh diff fluid in it
Use it until it wears out

 

drift I wanna get into it a little bit

 

well damn, i saw that one coming

 

the stock s5 viscous lsd is not much use for drifitng. you might want to get a s4 clutchtype lsd but they wear out too quick for drifting, and if you do some hardcore drifting every week, I recommend an aftermarket lsd. I'm saving up for a Mazdaspeed 2 way clutchtype lsd, but it is very pricey. I recommend you read a lot before you start getting into drifting. It takes studying, practice, skill and technique to drift. It doesn't seem like you know much yet, I advise you to not drift until you know more about the car and drifting its self. I've seen some disastrous crashes from attempted drifts by people that had no knowledge of drifting. Its not funny when it happens. I am still learning myself, but have never really messed the 7 as much as did with the miata which is underpowered and lightweight. I suggest you practice on a underpowered and lightweight car first. it will prep you for a more powerful car. My first NA 91 was hard for me to learn off of. when i got a 90 miata i learned a lot faster while watching the drift bible over and over and studying while reading about drifting info. i swapped in a 1.8 and I caught on better and felt better with the stronger motor. I recently got my 90 TII running and actually took it for a couple of slides in a big factory parking lot and the rx-7 was harder to maintain a good slide, because it grips really good, but i caught on faster than when I had the 91 rx-7 NA. Sorry for the long story, but its some good tips that helped me out.

 

Yeah, you're gonna want a clutch type diff, which comes stock on the S4 RX-7s; that 91 diff isn't going to do you any good. My diff has lasted me over a dozen drift events with no problem, and this is including some high speed events at Buttonwillow.

I agree with Eternal_Gamer, but the only way to learn drifting is to do it. Find the nearest drift event and go practice. Don't do it on the street for god's sake, the last thing we need is another news article about 'touge' with pictures of your mangled FC sitting in a ditch.

On that note, be prepared for a tough time if you're still on the stock suspension. The FC doesn't like to slide with the stock suspension. It's possible, but you're gonna have a hard time doing it...I remember have a couple FD guys try to drift my stock FC(Taka and Ryan), it was pretty interesting

 

I do plan on drag racing a bit... not all out drifting like some of these teenagers who think a resonator means power... (civics) I am just looking for a little fun and alot of appreciation for my wankel

 

as far as drifting on streets already learned that lesson the hard way about $1760
dollars later... talk about raped by the system.

 

Racing on the street in general is very dangerous, it's actually pretty sad to see the number of deaths related to street racing every year.

As for drag racing, a clutch will do you good there too. Once one wheel starts spinning, the clutches will lock the diff, so you'll pretty much have a welded diff when it locks up.

 

okay I see how the clutch works now. Also yes it is very sad about the street racing. Especially in here in vegas Almost every couple of weeks I hear something related to it... and pretty much all of them are high schoolers

 

I replaced a worn LSD on my UK '91 TII with a Torsen out of a S6.
At the same time removed the passive steer bushes.

What a difference ...Love it.
Its a lot more friendly than the 50lbft plate diff in my '81 racer
