T50 to AZ6..... At the CNC....

[DX20VT]

what about the Altezza 6 speed, or the silvia? 6 speed? or are they the same box?
as for 250hp....
with 4AGTE's regularly getting aorund 250-270hp at the wheels, this is a bit more than 250 at the crank. will this be an issue? (then again you can break any box with any engine.. almost.. with enough abuse)

If the gearbox you are using is the same strength as the Altezza one's I would be careful of using it on high HP cars,

i know that the had trouble with them in the good HP non-turbo altezza race cars,
let alone the turbo one's. the Turbo Altezza race car I had dealing with made less HP than me and shit boxes.
I would love the option of the 6 speed, but would really hate to spend all that money on a conversion to find it is not as reliable with good HP as the W series boxes I use at the moment.

And yes T50's are weak as shit on anything with more power than a standard NA 4AGE.

DX20VT - I have heard of some of the Silvia guys being unhappy with the AZ6 and breaking them... this is the first I've heard about Altezza issues. The Silvia GTR is reported to have 276hp and 202#-ft of torque in a 2800+# car. It should hold up fine in more than 95% of rwd "A" engine applications

unless dorifto bunnies are clutch kicking...

what the fuck is wrong with a dorifto bunny clutch kicking? i like my dorifto and my grip driving aswell, but i can't drag race for shit. a corner is a corner, doesn't matter how you go round it aslong as your carrying a shitload of speed on the exit .


adapter looks the shizzle

[oldcorollas]

no, there is nothing wrong with it, and lots of fun

just a bit harder on driveline than usual is all i was meaning
ie, shockloading on gearbox... can the roadster box handle that?

Abuse... that is NEVER a design factor... even in racing apps, the engineers TRY to design for both lightness and driver abuse... but any part will only take so much.

With that said..... If it can hold up to moderate to heavy abuse in a 2800# silvia that plants a minimum of 202#-ft of torque... how much abuse will a Toyota "A" series do in a 2000 pound car??? Can you say significantly more than a T50... while providing better fuel mileage at the same time.

This isn't a w Supra box... if you are in the 5% of Toyota "A" engine producing in excess of 280hp and 200# ft of torque, then this ISN'T for you.... but if you are planting over 200#-ft, do you need a 6 speed???

Can it br broken... yep, sure can... but let me simplfy this... there isn't a 4AGE (note none boost reference) in the WORLD that will break or damage this in just about ANY use....

Yeah makes sense, power wise it's a mid step between the T50 and a W5# box.

A six speed would go good in my race car,
but at close to 500hp my 'A series engine' would probably chew it up quickly,
even with the light weight.

Will be keen to keep a track of how they go though, as it seems like a good option.

hmmm t50 with bellhousing dry = 30kg.
Altezza J160 dry = 44kg.

worth the 14kg???

14 kilos... located between the axles - shouldn't mess with balance.

capable of handling in excess of 200#/ft

T50 uses 90 weight... AZ6 uses 30 weight... AZ6 will have less drag* then T50, allowing more power transmitted, and better mileage.


I'm still being patient with this... the shop clocked the adapter wrong**

T50 - 2ndry shaft is NOT directly under the primary
AZ6 - directly above one another....

[oldcorollas]

capable of handling in excess of 200#/ft

200 ft/lbs.... 270Nm??
thats only 12psi boost... it would barely handle a stock 4AGZE? let alone most turbo units around running 20

then again, some of them still use T50 successfully so it would probably survive for a while

I should clarify.......

The ONLY reported issues with the AZ6 seem to come from the S15 crowd. They have found that when pushed... they can break them...........

Just because it can be broken... doesn't mean it will... as you say many folks with in excess of 175#/ft still running T50s.

The S15 is 2800#s and has a min torque of 202#/ft. The mass of the S15 and the torque of an SR20DET seem to be its current "abuse point"

whats the advanatge of this:

"T50 - 2ndry shaft is NOT directly under the primary
AZ6 - directly above one another...."

[oldcorollas]

he just means, the angle between the main shaft and layshaft is different between the two boxes (T50 has internal "slant"), but machine shop thought they had same angle, so they made the BH with the wrong included angle, so the AZ6 would have been twisted to the same slant as the T50's internal angle between main and layshaft..

no advantage, just different setup.

[Sam_Q]

oh I see, thanks for the answer
