What a$$hole designed the impreza???

Well ive been offered a 45k mile box off an 07 wrx, just waiting to find out if the part number matches.
Thing is tho, the car has a 24kish api rebuilt engine so that should be good. But the box doesnt work lol.
I wont be after massive power, say 350bhp 350lbft at some point but the std box wont take it.

Probably worth have look on older TY754 which are stronger than TY752(New age) and many people run on them early 400bhp and some above 500bhp without the issue
You are probably need to learn how to drive,if you are killing the gearbox,as many people run on New age WRX gearboxes lot more and they're not broke 5 speed
Nothing is bullet proof,6 speed will or can break too,like any gearbox
Good luck there

The max I'd attempt on the 5 speed would be 330/330, even that may let go.
Even adding PPG isn't a failsafe, why do you think the STi comes with thicker/stronger driveshafts too?
The weakest component will eventually fail.
Honestly, either keep it around 300bhp or chop it in for an STi.

PPG again,we run our at 555.5bhp without the issue,on previous occasions we are run 490bhp plus NOS,wagon has been used on drag or track days and we never have any issue with the gearbox plus we run WRX Driveshafts and WRX rear diff
6speed is nice,but still I prefer 5speed PPG due gear ratios and whine noise of the straight cut

The UK turbo/ wrx gearbox is perfect for what it was designed for. Yes, if you start doing 7k launches and constantly drive everywhere like a tw&t, then yes, of course it will break, just like any other gearbox. I also understand that they are nicer to use on a day to day basis.
It's the only gearbox I've had the four scoobies that I have owned. (Two of those were classic sti's, so they can't have been that bad!) And it's one of best 5 speeds I have ever used with the integra type r being the best.
The main problem is when people start taking the wrx beyond the capabilities of the standard td04 turbo. If a transmission is rated at 300ft/lbs of torque on a light duty of say 800 hrs per year, 5% of that at full power, then it is very easy to understand why they fail when people start using then in a different way than what was intended. That is how a manufacturer specs a transmission. I know, as I sell marine and industrial transmissions for a living.
What I think some Impreza owners fail to understand is that for many people, the WRX offers the perfect compromise between power/speed/reliability, without looking like a boy racer.

The code on the box i took out was 77-TY754VN2AA
So it was the stronger box.
I just dont think i could live with a straight cut nox on a daily basis. Im getting older lol

How do you get a 2k return on a boggo wrx ? I struggle to get a grand from a bug wrx. Even with a gearbox to sell.
No offence intended, but 2k return is a big dream m8.
£400 engine
£150 box.
£40 for bonnet
£80 for brakes
£200 U.K. 300 trim.
Not much saleable gear after that pal.

It is a uk300 so has the hella headlights etc
Body panels arw not mint tho, stone chips and the odd dint etc
Well i stripped the box down earlier and its second gear that has gone.
All the syncros etc look to be in very good condition, no wear at all that i can see
Now thinking about trying to buy a new mainshaft, new second gear and replace all bearings and seals. As it looks to be in very good order.
Ill take it work when i go back and clean it all up if i can source the parts

Once you've made your dorrah on it you can get yourself an STi

I've not changed a gearbox on an Impreza, but most of the things I've done have been relatively straight forward (well more so than I thought for an idiot like me).
Try changing the throttle cable on an old school Vespa, or the rear wheel on a Honda Goldwing .

Well, i dont want to break it as i quite like drivimg it. But the more i think about what i want to do the more its going to cost of course.
I guess im going to repair it, but again its how to go about it. Just stick a second hand box in and hope for the best, or try and repair mine. Now i dont know where to get parts from, other than subaru and the nearest dealers is a good 30 mins from me.

TY754VBAAA's are rumoured to be one of the strongest early 5 speeds, the same as a P1 I believe. Again rumour, but I've heard people on here say they "can" be ok up to 400BHP.
Maybe give this chap a shout....

Oh, would the P1 box be a straight fit or would i need the rear diff etc? What about prop and shafts etc oh and clutch???
Cheers!!

From what I remember you'd need the matching diff. Good bit of info on this thread...

Managed to find mateys number on the P1 site, he still has box and diff in the car so i can check to make sure all is good.
Looks like this may be the way to go then!

Another good thread here....

As I've said before I have had customers running close up to 400hp on a TY752 Vers 3 transmission and never broken it in 2 years of competition [ winning as well ! ] And guys on TY754 in road cars with barely 300 hp breaking 2nd or 3rd gear regularly.
Remember that any TY 752 is at least 12 years old with 12 years of metal fatigue. Some TY754's are 11 years old............
I think that somewhere between 350 - 380 hp and 350 - 360 ft lbs is probably Ok for a 754 - above that level and you're on borrowed time, BUT, the later 2.0 WRX 5 speeders are stronger again, especially the drop gear bearings at the back which are usually the source of most noises. So a late blob eye 2.0 5 speed is about as good as they get.

Found a box and diff very local for £250, so will probably go that route and have mne rebult in the mean time.
From more research it seems that the P1 box has short ratios, so again not good for a daily.

If you found it hard to get the box off wait till you try and get it back on 7 out of 10 times it's a bit of a mission, done loads in my time from 6 speed to 5 speeds and its always better if you get someone to give you a hand
Hope you get it sorted

Cant say im looking forward to it tbh!
Hopefully picking the box up at the weekend but need to get new exhaust gaskets in the mean time. There is a subaru dealer local to where the bix is so ill pop in there and see if i can get some. Are subaru parts places open on saturdays?
