4agze trd diff

[dimitriske30]

Well yesterday I have disassebled my e51 gearbox to fit the trd sw211 that was originally constructed by trd to fit inside e153 gearboxes. I'm very happy to inform you that it also fit inside the e51 gearbox with no serious issues. If someone wants to do this upgrade he need the speedo gear and snap from e153 differential and 16 bolts from oem viscous lsd final gear. You can use this with lsd and with non lsd tulips. Finally everything solved.....Tomorrow I will full reassembly this and hope I will not discover any secret problem.

I imagine the Quaife option is more available and is a direct fit!

I imagine the Quaife option is more available and is a direct fit!

The true is that quaife is still available to buy new, but actually this is not clutch type. Also the new type quaife also needs exchange parts, I mean that it needs also the speedo gear and snap to be exhanged with the newer type e153 speedo gear. The older types quaife didn't need exchange parts but if you would like to use them in e153 gearboxes they need the older type speedo gear. Them fact is that quaife makes one type lsd for both e51 and e153 gearboxes. Most of the internals for these gearboxes are common.

If you prefer a torsen type lsd quaife is a must, if you prefer clutch type, like me, then there are also kaaz and cusco, that also need some exchange parts and the oe lsd tulips shafts from e153 gearbox.But what happens when you want to fit these groups in an e51 gearbox??? If you want to fit them inside an e51 gearbox then you need the oe lsd tulips from e153 or e51 oe lsd tulips and are very rare almost unavailable. The true is that you can use e153 left side tulip from oem lsd e153 gearbox but the right side cannot fit because e153 doesn't have right tulip but axle. If you want to do this mod you have to take your right tulip to a machine shop to make it fit. Hope that my experience will help someone.

I have fully assembed the tranny today.Everything is ok and now I can ensure you that both types lsd and non lsd fits with no problem. I have replace all the sychros. Toyota have exchange parts for sychros, they come with different part number and your dealer have to inform you for this. The newer type sychros have exchange toyota part numbers and toyota says that they are titanium coated. In the next three days I will intall the gearbox again back in the car and I will inform you if I have any issues.

[dimitriske30]

So the gearbox has been installed and after a small problem that I had with the shifter arm the car is on the road again. To tel the truth its like driving another completely different car. As for the diff, no clicking noise, like kaaz and cusco. So to make it clear for future upgrades sw202 is the part number that trd gives for e51 gearboxes and sw211 for e153, but sw211 also fit inside e51 gearbox, the only exchange part is the speedo gear and snap. Nice upgrade for me

Well done Dimitri

Pleased to read that you've got it sorted

A really good upgrade it seems

Thanks, I strongly suggest this upgrade, car is like "go kart", nice toy for someone who knows how to play with this, more more more more advanced driving.

Would like to do the same myself

I should imagine the TRD LSD is very hard to get & very expensive though

[PW@Woodsport]

A Mk2 turbo rev3 LSD will work just the same, to be honest using turbo diffs in the supercharger gearbox is pretty old news.

I'll have one for sale by the end of the week.

I'm also not convinced that there is a huge benefit on the NA as traction is rarely the issue it can be on the SC.

Will it fit the C52 transmission Peter ?

Unfortunately not. Only the E153 and E51 boxes.

Damn it

I already have a Mk3 LSD but was wondering about something better

Thinking of using 6 speed Celica internals + LSD to build myself a box

[PW@Woodsport]

I build those 6 speeds with LSD all the time for Mk1 owners, you got to know what you're doing, there are quite a few pitfalls.

Thanks for that Paul

I already have the stripped down transmission casing from my original box

And also have a Mk3 LSD

Celica boxes seem pretty easy to get

So think I will have a go at building myself a funky box & see how I get on

[stenky]

Peter, transmissions are fuc*in magic
Stripping them is just 30% of the success because:

There's a thing called differential bearing preload, which is tricky to set correctly.
Old vs. new bearing differential preload is not the same. LSD vs. open diff preload is not the same (lsd should be measured on input shaft, open and torsen on differential itself; i hope I didn't mess that one up)

So you need a correct spline to measure that. Also, you need a a fine, fine measuring device, which is capable of getting difference of torque of 0.1Nm. That's 400 GBP upwards.
Not mentioning the measure-guess the right shim thickness- assemble- measure procedure.

Ok, it might not differ after you reassemble your tranny the first time (not trans sexual), but if the bearing preload is not set correctly, the diff will chew up shims and bearings within hundreds of kilometers. So you'll end up replacing the gearbox, diff. and probably driveshafts as well in no time just because of the DIY approach. Which is fine, but not while handling transmissions with differentials being replaced. Gearbox is a delicate job indeed.

[Lauren]

We took apart an E51 box. I must admit, within a minute of prising it open we knew we'd never get it back together again.

[PW@Woodsport]

It's very specialized work, it has taken me years to become fully skilled at rebuilding Toyota transmissions and also make a load of special tools for each job. As Stenky says the diff preload is vital, i bought a Snap-on torque meter (not to be confused with a torque wrench) at a cost of £350 which measures 0-15 inch/pounds and needs calibrating every few years.

To give you an idea of the delicacy involved, a 0.05mm difference in shim thickness will mean + or - 3.5 inch/pounds of preload on the diff, and as Stenky says it differs for open/LSD versions.

I have to do a partial case rebuild with the output shaft and diff fully assembled before each preload check, in the case of C52/C60 diffs, you cannot turn the output to measure this preload, because even the LSD ones are open (being Torsen type) at rest, so the box must be built and stripped on every preload check.

This is before any of the difficulties in removing the 5th and 6th gear assembly are mentioned, but i'll let you experience that one for yourself

I wish you luck Peter!

[elbon50]

Thanks for that info folks

I have rebuilt gearboxes & final drives in the past

(Not recently & not with LSD it has to be said)

Am wondering if I may be able to hire a torque meter as it would not be economical to buy one
