T5 gearbox

[IhateRICE!]

hey all

I just want to know how much power a T5 could take before it destroys itself. because i plan to stroke my 304 to a 355 estimate about 440 horse's with similar torque. think it could handle that??

You can destroy one with a stock 5 litre if you continually launch hard. 355 and they would be marginal. I'd be looking for a 6sp conversion.

As above, T56 conversion. Do it once, do it right.

I blew 3 T5s with a stock 5L.

Exactly, do it once, do it right, TKO-600 without a doubt. T56's are over-rated.

You could build a T5 to handle it... just don't ask the cost.

If cars running 1000hp can't break them, they must be good

You could run 1000 hp in a gemini on the street with skinny tyres and not break a T5 :P, but also you could snap one in a stock V6 VQ on the track. Extreme example but the cars weight and the traction play a big part in driveline life. Near stock LS1's snap T56s and tailshafts and axels like they are going out of fashion on the track

I was talking about a track car.

Track cars.... we've broken 2 in the last 2 years behind a supercharged VY R8 track car. $12,000 later for a box that so far is going a lot stronger (from the US... bit cheaper then the $30,000 holinger conversion).

There is a T5 running behind a 383 twin turbo pulling 1500hp.

The TKO box is a better option for the fact it's 20kg lighter and costs less to strengthen.

Bah, just put an auto in it....Much less messing around.

the word "butterbox" comes to mind.

be done with it stick a supra box in it... :P toyota W58's can be mounted up to a 304 (hydraulic clutch however) and don't cost too much. i looked at a T56 when i had my ss and the cost of a used box alone was hefty.

It all depends how good you are at driving stick, and how you plan to treat it. I thrash the living hell out of my T5, but I rev-match and go a bit easier 1st-2nd when I'm giving it cheek, and it looks after me.

On the other hand, if you plan to flat-shift and clutch-kick, I daresay you won't see more than a few months' use out of it if you're lucky

Any update on T5s ? I keep destroying mine and im only making 160 with a cussion button clutch. I rev match alot but some of my mates who have had to drive the car are hopeless

Get a T56. T5s are useless.

What's required to be modified in order to run a T56 ?

Mal Wood sell a kit where nothing needs to be modded (except maybe bashing the trans tunnel out abit, its abit of a snug fit)

Where do i purchase the kit from and do you know the price by any chance? Not sure who that is ..

Cant remember the exact cost, but it was a few years ago, so you'd be best emailing them to find an exact cost.

Its about 5 ot 6k for a t56 conversion… Was gonna do this a while ago and quoted it and worked out everything you need would add up to about $2500 minus the t56 and labor…

[vscom88]

Yeah .... No thanks
I guess il stick with the Old T5 then.

On the other hand is money grew on a tree ... Would defiantly consider this

No one has mentioned a dogbox?
To break a T5 you would have to drive like a twat 24/7 imo.

Nah - the bearings on the lay shaft are really under specced. Clutch dumps and hard launches kill them very quickly. That said, if you drive smoothly and don't dump the clutch off the line every time they do last very well.

I Sometimes do clutch dumps, running a cussion button clutch but the problem i face is 3rd gear .. it seems to go in but not come out and this is the 2nd time its happened since i got it rebuilt

[UW1SH]

I reckon it would be worth it.. Better fuel eco (maybe the streets depending on gear ratio) and cause of the extra gear for it to rev lower down the highway. can smash it at the track all day long and it will still shift smoothly the next day etc.. Bit pricey tho but its a good investment
