TRD t50 gearsets

[z_brutalis]

Hi i was looking at my transmission options and i was wondering if anyone has had any experience with the trd 3 and trd 5 gearsets for the t50

basically my goal is roughly 220hp at the wheels and i have a feeling this will destroy the t50 if i drift or race. so my question is

do the trd gearsets increase the rated hp for these box's and how likely would i be to blow it if i went for more power.

also what options are there that will keep the standard shifter position and for the price is the t50 gearset worth it. i haven't found any testimonials about them or power rating figures yet so i am trying to get an opinion on them from what i have seen the seem like they are a cheaper alternative to the w58 conversion but again im not sure if they will hold up as well.

any info on this would be greatly appreciated as the transmission is my starting point.

how much do you think they will cost?

a W58 is still cheaper I reckon if you avoid paying a premium for all the bits

I don't see how changing the gears would increase the strength in any way.
and the W5x would by far be the cheaper option.

Btw, why is the transmission your starting point?
The T50 will hold up just fine under all conditions if you are gentle with it...
If/when it does go, wouldn't that be the time to think about upgrading?

To get a stronger box i believe you need to get away from helical gears and go to straight cut teeth.

The gearset alone is 2500 dollars, quaife do it too, so does Albins, I think Hollinger will make gears to suit aswell from what Ive read, but you will pay more through those companies than TRD.

Dont quite understand how it could be seen as a cheaper option as you would be looking at 3 grand parts alone by the time you buy the bearings and seals you need to put the box together again.

Trd gearsets are nothing more than different ratios...

No stronger at all...

220hp is a sizeable figure if you plan keeping it n/a...quite interested to hear ur plans...

I think Glen, Celica RA45 on here was selling a kitted up W box from Albins? This was a couple of months ago. I think it was $3500, which is pretty cheap considering.

That would be a better option.

i have been told not to get TRD go with Hollinger apparently far better quality/strength

you wont get a T50 gear set out of holinger, no way. they did a few probably over 10 years ago now... they dont even list it on their site even in the "vintage" section.

as mentioned quaife, though theyre not too practical as you have to send the box back to them for machining..

PAR do as well though a few qld race guys have broken them.

albins do gearsets too but they re use some part.. cant quite remember which. i personally wouldnt want to use 2nd hand parts in a big $ CR gear box.

TRD is really the best option if you want to stick the with T50 but its no stronger.

so.. realistically i view keeping the T50 and changing the ratios really only useful for a club level sprints type car. its too weak for drifting. and its not really good enough to race with. a W box conversion is cheap and compared to any CR gear set. youre better to start there, and then modify that box.

220 hp is a lot though. NA. you will need a proper engine builder to get there.

if youre going turbo you dont need the CR gearset at that power level.

lol i never said i was planing on keeping it na i am building a 20v silvertop twincharged to keep it feeling like a na engine. i know its pointless but i doubt its been done and i dont really have a budget for the car.
basically all im chasing is a stronger gearbox that will keep the standard shifter position. the gearset goes for $1500 and based on what i have seen seemed like it would be cheaper.
from what i can tell this gearset replaces 1st 2nd and 3rd. 4th and 5th stay the same. they also seem to be straight cut gear teeth.

my only concern is that i want to keep the shifter in the same position like i said im open to opinion and based on what you guys have said a w5x box is probably my best option. so my question is what w5x box sits closest to the standard shifter position that will still handle that amount of power. do the cross members have to be modified and what company still makes the bell housing adapter and what is the best one to go for. also the reason i want to start with the transmission is that i want the ability to bolt the engine in and not be losing power to a transmission while tuning. the engine is currently being built. i have a vague idea of what needs to be done to the engine to achieve that power figure but there is a build thread in the owners section listing what the plans were for the engine. most of the parts are recommended to me by my finance's dad who twincharged a twinky years ago. but like i said its mainly proof of concept at this stage im just doing the rest of the car to suit because the 20v performance parts are hard to come by so im starting with what i know i will have to change because a 20v silvertop alone would stress a t50.

Get the w-box conversion adapter plate from that guy in tasmania, it'll put the futhest forward w-box shifter right through the stock hole.


I would have bought it, but at the time I couldn't get ahold of the guy and ended up making my own.
