Project Overtime

Is that top 1 the 182 gear box ?

 

Thats not an "S" box - They have a cast cable mount and screw in selector.
The 182 S54 looks identical to the S53 but has a Camry type starter, I have been using one for the last 3 years


Pic shows S54 from a 202

If you fit the cover plate on an E series, the MR2 diff does fit in the GT4 box, making it FWD

Dunno whats goin on here?
Both boxes I've never seen before, it's an "E" series with the starter on the wrong side?
Camry/MR2 etc looks like this. All use the Camry type starter, so an easy mod for you



Bottom is definitely NOT 185 and once again the starter is in the wrong place altogether, also the 185 has a lever to disengage the VC as on the 165. Later boxes don't have the lever so this may be from a Corolla 4x4?
Also, what is that rod sticking out the top? - a H/L range selector maybe?

165/185


The tail on that transfer also looks weird? This is a 165/185 transfer case

This is the box to have, ST205 with no VC lever and dual synchros

 

I've said that myself - many times!

Pretty sure that site is wrong, unless it's something we've never seen before, that is also one of the last "narrow" boxes with a pressed cover.

The starter placement indicates it mates to a 4A/7A block, it will not work with a V6 or "S" motor

"Your" box is more of a worry, have you bolted it to your block yet?
The 4A-GZE box is similar to ours but has a different starter etc, the pattern looks the same but it WILL NOT bolt to the 3S/4S/5S blocks.
I suggest you shoot over and check it mates with your block before you spend a lot of moola on something you can't use


early ST165 (JDM only) - Oompa has one

This box has different ratios, 4.2 diff and no VC. All JDM's are 4.2's wheras everyone else has 3.9
No VC, cable speedo, pneumatic actuator for engaging the rear wheels on dirt only
No front or rear LSD

ST165/185
VC and horrible synchro's, the one we love to hate. Has the VC lever, cable or electronic speedo
Easy to tell this is from a ST185, it still has the electronic speedo drive fitted
ST165 has no LSD rear diff
ST185 has LSD rear diff

ST205
Improved synchro's, no VC lever, electronic speedo. Rear diff has LSD


Camry/Solara V6
Similar to MR2 turbo but has no LSD. Mafix has one fitted in Nemesis, electronic speedo
All have 3.9 diffs, where the MR2 is 4.2


Curren/Caldina box
The last type is narrower and was used in the RAV4 as well, has a pressed side cover.
No interchangeable parts I'm told?
Available in FWD or 4x4, electronic speedo. FWD has LSD diff

 

I've asked the experts on Toymods to identify those two, should have answers soon as they are 4A/7A masters

 

That's why I bought a bunch of broken boxes in the hope that I can assemble 1 good one.
Now just to find someone who will let me use their press so I can strip and swap parts over.

 

This is the 165 box on my gt4

 

Yes, that's a 165/185 box, best upgrade is the 205 box with a 185 rear diff.

Once we know what that box is you could re-sell it and try get your money back, I know the 4A crowd are crying for LSD's

I did get an answer on the 2nd box, it's definitely a Corolla item
You can tell those poms to wake up and re-heat their coffee, sorry tea


Your's has caused quite a stir, most are saying it's a Curren box but they can't see the starter location

 

Can you post some more pics of your box - much confusion here!
Don't panic till we get this figured out

Just for shits, here's the AE92 "E" series box which isn't like yours at all

 

Pics don't show the starter hole but reading back there you said it was in a ST184 and bought some shafts for it as well

If that is the case then you have no worries, it is an ST185 box but I need to see the starter location.
Another difference between 165/185 is the 185 had cooler pipes while the 165 had a U shaped oil pipe at the front.
The ratios and synchro's are the same on 165/185

I Like the "Purple people eater" btw, the more I look at the ST20x the less I like them, weird

Buy some scrap boxes for spares as they tend to have different faults, ie one I bought has the reverse gears sharpened with a dremel so may have some new parts in it.
Also I may be able to supply gears in better condition

You need to study the bought LHS shaft very carefully, no way it should have chewed up the diff inner like that

 

what a confusion is my gearbox a lsd then so many out there sorry to chirp in.

 

Howsit Nando, yes it is LSD, not as good as the aftermakets like this one (Matt's) though.

It is the simplest LSD and works on tension (friction) supplied by washers, the older it gets the less the friction so I'm going to try and fit the thickest washers I can, here you see them with holes in them



The MR2 diff only has 2 washers, these others all have multiples - like in a multi-plate clutch
The pinion is fixed, wheras on the aftermarkets it can move and vary the amount of lock to the wheels in 1.5 or 2 way diffs.



Here's the whole MR2 diff, much more parts than a standard diff but less than the Quaife, Cusco, Kaaz etc


For those that are lost - we need an LSD to convert a GT4 box to FWD, the 4x4 diff simply won't work without the rear wheels and you can't buy an open FWD diff for these boxes.- (correction, you could steal one from a Camry/Solara V6)
The MR2 Turbo uses the same box in a RWD config, luckily there are aftermarket diffs for the MR2T
The GT4 diff is actually 2 open diffs combined into one - complicated I know, and only the Rally teams had access to LSD's at a cost of $5000ea
