GTUs Rear End ok for Drifting?
Ive done sone searching but im at work, and the filters are a pain to get around, so I haven't found much. How is the GTUs VLSD at drifting? I have an opportunity to pick one up for a decent price, but I'm not sure how well it will hold up. My GXL rear end is pretty much done for, it hasn't locked since the first day I swapped it in...

Not to mention you're way to far away for me to be interested... |
Well, I assume it's just a standard N/A lsd just with a different gear set in it. Sooooo.... Just as good as any other N/A lsd.
|
Not quite, it has a viscous coupling in it instead of the clutch type. I just want to make sure its durable enough to handle it.

As far as lockup goes, everyone raves for a Torsen or a rebuilt clutch type. The vlsd locks up differently, I never had a problem with it, but I think the others lock up faster. Just an FYI, if you run the 4.3 and some 15's with low profile tires, you will love it. The car will be noticeably quicker. Add a miata gear set to that equation....... It's awesome for an n/a. |
Being viscous would make it a standard S5 lsd.
What are you running for engine and mods? |

The diff will hold up, it's the stub shafts that won't. If you're still n/a you'll be fine, but if you're turbo swapped, you will eventually break a stub shaft.

I have the clutch type in it now from an 86 GXL, but there's a drift even coming up in like 2 weeks, and I won't have time to learn how to rebuild it by then. You mentioned Torsen, Does the Miata rear end really just bolt in? Will I need the Miata half-shafts? I read a build thread once about a Miata transmission swap into an FC, and it looked ridiculously labor intensive and expensive. Is there a way to just transfer internals? Cause I have like 5 FC transmission that are all bad, so I have the cases, lol... |

Definitely still N/A. All 117HP of it... :blush:

I had it done, and my total cost was around $950. I bought a used Miata trans from a 2001 car with 11K on it for $375 and had it shipped here from Florida. I tried to take it apart, but after getting the housing off realized it was way over my ability. I took it to RP Performance in at Summit Point, and Bret Machined the input shaft and installed the gearset into the case fore $500. After that I just got some gear oil and put it in. It's a lot more fun(You can start from an uphill stop in 2nd gear!), but don't expect the car to be a highway cruiser. With the 4.3, Miata gears, and when I was running 15's 80MPH was about 4200-4300 RPM. |

viscous sucks.. its slightly better than open. you can either weld it or id suggest finding a stock s4 clutch type or an aftermarket. torsen diffs are about the worst you can have for drifting. they may be ok or even favorable for road racing but are probably rated even lower than open diff as far as your questions go
to avoid these bullshit answers, you should frequent the drift section more often. less people talking out of their ass over there. |
vlsd do suck for drifting.
The internal fluid will overheat and will let go, then you will have an open diff until it cools back down. Torsen diffs work but they are very unresponsive vs clutch types. Torsens initial bite is linear compared to a clutch which will bite right away. Also.....who has diff stubs for a GTUs S5 4.3 diff. I need a pair BADLY!!!! Mines broke..... |

I've never done any drifting, but there's an event coming up that I'd like to get onto the skidpad for. |
BASICALLY, all I want to know is if the damn thing is going to break, or if it will be ok. I'd hate to take a rare diff and blow it up the first time I use it.
|
You'll be fine. If you break it, it was broken anyway.

Nice. Never seen that before...
|
your diff wont break but after about 20 seconds, you will be mad that your car wont slide any more.. especially on something little like a skid pad and being new to the sport
|
Really? Crap. So should I not even bother swapping it in? All I have right now is two open differentials. It would have to be better than that right?

Take the the VLSD out. Grab the clutch type lsd out of the gxl diff put some new clutches in it and oversized thrust washers(to shim it) and jam it back into the 4.3 gearset.
