Guest Terry S Posted September 17, 2002 Share Posted September 17, 2002 Hi Guys, this is mainly directed at CW but please feel free to chip in. I have been thinking for a while about having a TRD Diff put in. Apparently the install is a major PITA, it comes in kit form & you need to strip down your existing diff to fit it. Do you know anyone you'd trust to do this. I am kinda paranoid about my diff locking up at 180:rolleyes: Quote Link to comment Share on other sites More sharing options...
Terminator Posted September 17, 2002 Share Posted September 17, 2002 Sorry to HI-jack, but are you saying that the TRD kit just replaces the internals. As I have a spare diff (as you do)and was wondering if it would be possible to uprate the internals. Quote Link to comment Share on other sites More sharing options...
Branners Posted September 17, 2002 Share Posted September 17, 2002 Couple of blokes on the NZ mail list changed to TRD diffs about 2 years ago and they said their old diffs were available for sale so I can only assume it was a full swap job. They also said it dragged their 1/4 mile times down due to extra drive train losses and that the only reason they swapped to TRD was because they thought they didnt have an LSD already and it turned out they did. I can check ifor more details f you need me to. JB Quote Link to comment Share on other sites More sharing options...

Alex Posted September 17, 2002 Share Posted September 17, 2002 If installed by a Toyota garage they are fully warrentied. Might be worth thinking about. The TRD Diff itself is a better bit of Kit...but Terry, if you are serious about your car...which I know you are, I'd talk to Quaife about getting one of their ATB diffs fitted. They don't have an off the shelf solution for the Supra but if you could supply a diff, say Phil's spare, then they could investigate making one. This would allow you to pick the gearing. And Quaife's ATB's are likely to be "better" than the TRD one. Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted September 17, 2002 Share Posted September 17, 2002 Tat's athought Alex, although it sounds an expensive one! Don't suppose you have an idea of cost? Quote Link to comment Share on other sites More sharing options...
Alex Posted September 17, 2002 Share Posted September 17, 2002 I did ask them...ages ago but I really can't remember...what stuck was the 6k for a transmission I have since realised wouldn't fit the Supra. ...ffffhheeeeewwww that was close, I nearly bought one! I would just e-mail them...they responded quite rapidly to me. [email protected] Can't hurt as it can only be too expensive. How about carbon driveshafts and propshaft....just incase its all too much for the stock units! Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted September 17, 2002 Share Posted September 17, 2002 I'll ask then wince ready for a reply:D Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted September 17, 2002 Share Posted September 17, 2002 If you were to bring me JUST the diff unit and the TRD internals i can rebuild it with those within. I am a bit pulled out right now and don't want the ramp tied up for too long. I may have order shims and stuff, meaning if I drop your diff out I have a dead car on the ramp for an indefinite period :-) The TRD plate diff is better than the Quaife. Their gear type diffs generate insane amounts of heat in a powerful car. I suppose a lot depends on your envisaged usage of your car, is it for road, road / circuit, road / drag, or what?

Interesting fact number 10001: The Supra does actually have a hollow propshaft so i'm not sure how much of an advantage a carbon one would be. Anybody know if the drive shafts are hollow ?

Terminator Posted September 18, 2002 Share Posted September 18, 2002 When I canged my diff, the shafts felt pretty solid to me. Nothing like a good firm shaft SIAT. Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted September 18, 2002 Share Posted September 18, 2002 Chris, do you know if the TRD diff will fit into a Jap casing OK? I think they are the same as the UK's apart from the oil cooler feeds. Speaking of which, do you think the oil cooler is essential with big power. I am still running the J spec with the special oil you sent me. Quote Link to comment Share on other sites More sharing options...

I am still running the J spec with the special oil you sent me. I am almost certain it will, it's a Jap made product and as far as I know the casings are sized identically. Oil cooler would be nice for circuit work if you intend running for more than say 30 minutes at a time. If it has NOT got a cooler I don't think I'd worry too much about fitting one myself. Decent oil will sort it out, but be careful, the TRD LSD will need a special oil compared to a none plate type LSD or an open diff. Quote Link to comment Share on other sites More sharing options...

I thought CF shafts were more to do with safety then strength, they do less damage as the disintergrate rather than smashing the crap out of you car when they snap?

Keith C Posted September 21, 2002 Share Posted September 21, 2002 Plus isn't it that a CF shaft is lighter and twists less for a certain amount of torque, thereby reducing transmission losses on two counts. Quote Link to comment Share on other sites More sharing options...
