Justin Posted October 25, 2005 Share Posted October 25, 2005 Nope, tracks straighter, making drag racing easier. In the US, it is about the only mod shared by the hardcore drag racers and track racers. Oh marvellous Syed thank you very much. Now I'm going to have to bloody buy one aren't I!!!!!

suprabrown Posted October 25, 2005 Share Posted October 25, 2005 don't think about it,,,,,,,just do it It will all be over soon!!! If you are anything like me as soon as you start talking about it the next thing you know the wallet is out and the girlfriend is upset Don't worry about the wet, you need to push the car i.e. 2nd turbo coming in at WOT before there is too much trouble, and then you *should* be expecting it cheers mark brown (with the TRD LSD ) Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted October 25, 2005 Share Posted October 25, 2005 Mine car has have one on for a good while now and I love it. Like a big MK2 Escort now with an LSD. It will pick up the inside wheel slightly on very tight turns. A word of warning though. I have heard others that are pretty noisey. Mine is a quiet as a stock diff ( and they should all be a quiet as a stock diff), so not convinced the ones I heard are fitted correctly, or perhaps they didnt install new bearings at the same time.

Chiefgroover Posted October 25, 2005 Author Share Posted October 25, 2005 I'll be buying one come early 2006 when i start to drive it again. PHR 3.27 final drive is also a consideration. Thanks for all the relpy's. Quote Link to comment Share on other sites More sharing options...

Mine is a quiet as a stock diff ( and they should all be a quiet as a stock diff), so not convinced the ones I heard are fitted correctly, or perhaps they didnt install new bearings at the same time. Mine is quiet, making noise only on tight turns/parking etc. But a stock Torsen is pretty much silent. A Plate diff will never be as quiet as a Torsen, even a mild one like the TRD. May I ask how many you have heard Terry? They are pretty damn rare. Justin, sorry mate, you will thank me later! Quote Link to comment Share on other sites More sharing options...

Or you can see how much your local Toyota dealer want for a new one and swap the wheels.

Lucifer Posted October 25, 2005 Share Posted October 25, 2005 Give him the same gearing as a JDM 6 speed All PHR are doing is selling a JDM 6 pinion wheel LOL So if I have an auto, how do I make my gears longer? Quote Link to comment Share on other sites More sharing options...

Out of interest, where they autos or 6sp cars? At what point did they make noise, just when parking/tight turns, or...? One thing I suspenct, very simple, is exhaust noise. If my exhaust was as loud as some models, I doubt I would be able to hear the diff at all. Quote Link to comment Share on other sites More sharing options...
Miguel Posted October 25, 2005 Share Posted October 25, 2005 I've heard one on a manual car that was real bad on corners and hard accell. Clicked major bad on parking and reversing and whined like hell. Was fitted by a so called tranny specialist ( no one on here may i add) and it turned out to be they had used old worn bearings and the gear tooth line up was well of ...Most of the ones I have heard been real real quiet like stock.

suprabrown Posted October 25, 2005 Share Posted October 25, 2005 no noise ...... so far on my LSD I would think most noise is due to not being fitted correctly????? But not being an expert I could be talking rubbish appart from when I first set off in a morning, I reverse back then drop it into drive and set off on a full lock turn into the road (a bit of tyre scrub sound).....you can't tell any difference from stock - noise wise.....

LOL both 6 spds Syed ( not sure about Matt's experience) but a little lost as to what the gearbox has to do on it. Always low speed as they were not my car. And no, it is not the exhaust note hiding the noise lol. I am off all day today with the kids if you want to come and hear it. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 26, 2005 Share Posted October 26, 2005 Plate type diffs, when set up with the sort of preload you usually need on a race track, generally make horrendous noises. My Skyline positively alarms passengers when manouevring around, it bangs, shudders and hops. It's just the plates freeing with a jerk, nothing whatever to do with the actual crown wheel and pinion gears, the diff bearings or the gearbox. The TRD diff, as it comes stock, is set relatively loosely, but nonetheless has a LOT more LSD action than the standard option Torsen type diff. If plate type diffs make a lot of juddering and craking and banging a specific oil additive can help by altering the proeprties of the diff oil against the plates. It often works in mild cases, most race type set ups defy being made quiet and civilised. Diff *WHINE* is a function of incorrect crown wheel to pinion clearance or preload set up, or worn bearings. Just plonking in the TRD diff (which IS NOT really the diff as many people wrongly imagine it, the actual crown wheel and pinion gears, it's just the centre section, you re use the original gears), will often cause nosie, and almost certainly premature wear, as production tolerances on the centre section you buy mean the gear spacing will be different from how it should be. Hence the need to re set the crown wheel and pinion clearances to do a proper job. This entails accurate measurement with specialised tooling, and re shimming things.

Chris Wilson Posted October 26, 2005 Share Posted October 26, 2005 Well Mig is a Magician then. Anyone who wnats to hear mine is more than welcome. I am sure he is! It would need to be a lot out to be very noisy, only a little out to create abnormal wear. Perhaps the tolerances stacked up favourably?

Paul Whiffin Posted December 29, 2005 Share Posted December 29, 2005 When I fitted the TRD diff to my car it was noisy on tight turns, I then changed the oil for a different type and that cured the noise more or less completely. What oil are you using in your diff Terry? Quote Link to comment Share on other sites More sharing options...

Paul Whiffin Posted December 29, 2005 Share Posted December 29, 2005 Wouldn't have thought so, we did exactly the same thing on 2 customer cars and that cured the problem on those to. Quote Link to comment Share on other sites More sharing options...
