Gearbox recommendations for a 4agte

[Maximum]

I'm still considering using a turbo 20 valve for my project aw11 - One problem is getting a gearbox...

If I can get away with the lighter c52 gearbox, that would be great - Partly because they are going to be much easier to come by than the gze gearboxes (E series?)


I'm looking at pointing around 200hp at it - so what I'm really after here is some personal experience with this kind of setup.

Can the c52 handle that kind of power for an extended period of time? if so, how long can I expect it to last?

Thanks experienced toyspeed members!

No idea if C** can handle it but E series boxes are easy to get and cheap. Its the E58 lsd ones that are harder.

if i was building a car club vehicle with a 4AGTE in it, i'd use a C56 in it. IMHO unless you are wanting to push over 300HP thru it, then a C series box is OK. If you're wanting to do hard launches with grippy tyres then i'd use an E series box.

I will be using c56 with lsd in mine, (when i get there)> But I have fwd so not sure how the driveability will be affected with lsd in your aw11?

What box is Bazda running, in his 7agte(?)

I had spider gear failure on a C52 with stock-ish silver top, and no, I don't do burnouts. I also had ring and pinion failure on a C160 behind the same motor. Also both of the boxes had crappy synchros. C series boxes are relatively weak compare to E series, but E series have really shit ratios unless you mix and match.

thanks for the information people,

If i can get hold of a lsd box, that would be ideal. But that may be tricky..

I'd like to stick with the c-series if possible, since I understand they are a lot lighter?

[xsspeed]

Yeah I don't know sh1t about e-series boxes sorry.
Which 4agze did they come out in? All series? I'd like to know more about them if they are suitable for higher kw setups.

i have a lsd e series wicked box the diff is pretty rough, it takes a while to get used to they are pretty hard to find, there is a guy in rotorua who has them from time to time he is a wrecker they are around $500 tho.

[AceSniper]

c series will take it but a lsd will help (lsd=4spider diff stock=two)

[Maximum]

So if I was going to go for an lsd box, are the c-series lsd boxes more common than the e-series?

[xsspeed]

ae101 facelift gt apex superstruts, and ae111 BZx superstruts had c56 lsds I think.

I really wish there was a definitive way to know if a c series gearbox has an lsd -
I've heard of so many ways to tell -

- "You can tell by the size of the diff casing"
- "If you can see all the way through the drive shafts, its not an lsd box"
- "All supercharged mr2s had them"
- "All e series boxes are lsd boxes"
- "All black tops have lsd boxes"
- "All superstrut levins had lsd boxes"

None seem to be all that believable...

Maybe Mr Revhead can shine some light on this?

[xsspeed]

above is what revvy told me

BZR box is LSD but no good for you been 6speed the lsd will fit c52/c56 (torsen)
BZ-V box is c56 lsd (torsen)
seen no factory ae101 c series lsd's
some n/a aw11 c50/c52's have TRD plate type LSDs
gt starlets run a c52/c56 there factory lsd is viscus and has a different diff housing no good for 4age? also longer final drive

c series box's...........
If you look in the axel hole and see a pin... its open...

Solid center... bit like a pin but no gaps is a torsen bz-v/bz-r LSD

Solid looking center with a hole drilled in it is a plate lsd... pending on the hole you may be able to identify the brand.

All ae101 gtz's? E series had viscus LSD's? (not the same as c series....)

[Maximum]

What kind of weight difference is there between the c-series and e-series?

[Bazda]

If you change to the E series box you will also need shafts and a new clutch plate to suit the spline difference.

I can tell you the E series box is HEAVY.

I'm sure the C series will be fine, just run some good oil in it like redline shock proof.

[85AW20v]

E series would be about 20-25kg heavier. Internally, it's basically the same as whats in the SW20 N/A and turbo and those cars don't break their gearboxes. Driveshafts are about 30mm as opposed to about 26mm for the C series.

I orginally put an E-series in my AW when I fitted the 20v and had exactly the same lap times as the bluetop and C-series box. I had driveshaft problems so changed back to the C-series and picked up 3 seconds a lap on the old Taupo track. Ii seems I was using too much grunt having to drive through the much heavier E-series box as the box was the only change between meets.

Hope this helps.

Hey,

Thanks for the info - that is very helpful.

I guess the lighter box will definitely make the car quicker around a track.

It's the strength that is more of the issue - If you are running a c series on a 20 valve, I wouldn't expect you to have any problems. A c series on a force fed 20 valve might have a bit of a short lifespan...

If you look in the axel hole and see a pin... its open...

Solid center... bit like a pin but no gaps is a torsen bz-v/bz-r LSD

Solid looking center with a hole drilled in it is a plate lsd... pending on the hole you may be able to identify the brand.

I know of a guy who replaced the auto in his corolla wagon to a Manual. The gearbox based on that description was a non-lsd box. But, when fitted to the car, was in fact an lsd box...
That's what I mean - I've heard lots of supposed methods to determine if a box is and lsd box, but several times, found that in reality they don't stack up.

a friend of mine fitted a AW11 AGZE to his AE82 and used the std C52 AE82 box, he gave it DEATH, sometimes with sticky tyres and all he ever broke from a stub axle (bolt on type AE82 axles, the piece that comes out of the box)

run c56 internals in my starlet. hoosiers and over 200kw at wheels. hasnt broken yet,

syncros on c series are pretty average as others say, latter model boxes seem to be better.
