Stronger Gearbox RWD 4agte
|

Last night the gearbox started to make a real sick whining sound, like it has straight cut gears (but it doesnt) Its just a standard sprinter 5spd (T50?) So its going to need replacing. Is there a stronger gearbox that bolts up or minimal modification?
If it needs to be rebuilt, Is there any good places in Brisbane?
Thanks

sounds like you've killed the input shaft bearing if it whines in all gears.
only really strong option is a dellow or equivalent custom bellhousing to match up to a supra box.
it wont be cheap though, $475 for a bare bellhousing!

Here we go again  Read a few of the other posts about this, as it's been discussed a fair few times already recently!
Main point is, once you bust the T50, you've got to be prepared to part with some $ and put in a bit of effort to get a W box stuffed under the floor. And the dellows bellhousing I have spoken about before! But yes, it can be done (even a fool such as myself can manage it!)

the supra box is your only alternative option. both strength and price wise. still it wont be cheap.

Supra box is not your only choice. I had the same problem with my 4agte, i've used a steel case celica box (w50). All I had to do was make a 12mm adaptor plate from the block to the 18r bell housing, shave 5mm of the bellhousing. I used a 4agze starter motor under the inlet manifold and ze flywheel/pressure plate, and modified gearbox crossmember. Been running this setup for 2 years (side stepping the clutch at 7000rpm in 2nd gear with 225 tyres) now with no problems.

I like the sounds of that TA22, no dellows, Z flyeheel etc. any idea as to an approximate price breakdown?
Also roughly how much grunt are you whacking through the 'box?
I also heard that that a couple of Wxx boxes have pretty lousy ratios.
Do any of the Wxx boxes use the same mounting pattern?

I had all the parts and access to the tools so it cost me nothing. But to machine the bellhousing i think it would cost about $40-$50.You will also need the slave cylinder with the 18r g/box (remember it sits on the right side not left like the t50). In poor tune I had 195hp at the wheels.

In 2-wd class our domestic rally geezers go for Volvo straight cut gearboxes - even when running Corollas. Volvo boxes are cheap and strong, with suitable bellhousinf they can be bolted onto anything.
Here's a pic of such Volvo box.

Sorry, don't know from which model Volvo they're from. I could find out if it's definately cruicial.
I think it really doesn't matter, it's just up to mechanical ingenuity to bolt it up to Toyota engine. If such task can be tackled, such hobbyist can bolt any transmission to Toyota.
I'd reckon the old 200-series Volvos could make a good donor car, also the 700-series. Those are engineered to withstand 2,3 liter turbo gasser engines.
Also rear axles from such Volvo's are bolted onto Toyota in rally use.

If the input bearing is gone, would'nt it be cheaper just to go to a bearing place, get a replacement and do it your self? I replaced 100s of bearings in machinary and tractors and none have ben more than $150.00.
