im sick of having rebuilds and post this as a warning to anyone with 350bhp+ on the standard 5 speed box.
im now goning for a 6 speed after wasting time and money on rebuilding ****e 5 speed boxs.

not sure on codes mate but ive blown my99 uk turbo box, that was 2nd and 3rd.
then ive had a 98 jdm lower ratio box, fitted blown the diff in that .
Then ive just had it rebuilt with a new diff and uk 5th for more top end and its recked
3rd.
Not woth rebuilding, better off with a 6 speed in the long run.

lomas, how much have you spent on rebuilds and removal/refitting costs?! Must be a fair ol whack right? Nip this in the bud now and bite your lip and geta 6-sp in there... Then HOPEFULLY it will be a worry gone na another 'mod' ticked off the list.
Surely you can't really enjoy the car with this, seemingly, perpetual cloud of impending doom hanging over you?!

these topics allways make me laugh
i sell industrial gearboxs where i work and the best service factor you can get in industry is generally 1.5-1.8 this basically means a gearbox capable of 100bhp is capable of transmitting 150bhp for short but frequent bursts or 180bhp absolute max for very short periods . with todays modern tech what sort of service factor do people think subaru made their boxs to . lets just say 200bhp std now increase it by over 50% thats now 300bhp how long do you expect it to last i know 6speeds are running silly hp but perhaps the japs used the ford school of thought ie the mt75x gearbox out of the cossie well know for being capable of running silly power . all said n done i wasnt taking the p1ss out of op just stating what i know , also my mate stripped 5th gear out of a early sti ra box well known for being the strongest 5speed at only 340ish bhp but with loads of torque . its that what kills them not bhp

Been there mate went through 3 wrx boxes with only 310/300 on the old car.
Then got a forth box,a early sti ra one and its been perfect,inc 3 goes at the pod.
Then broke that car up and bought a type r with.....you guessed it...a broken gearbox...but it was cheap and still had the old ra box to put in it.
So that went in it,but now going for 500bhp,so played it safe and bought a WR1 6 speed box the other day.
So have one of those ra boxes going soon if anyones interested

He was told, months ago and by more than once by more than one person.
There's more to all this than meets the eye. Lomas' current box is, according to one of his previous threads, a mix and match made from 752 and 754 parts - not sure which casing has been used to make the frankenbox.
A significant contributor to his earlier problems, and the subsequent rebuild work, was the ill-considered purchase of a 752 short ratio WRX 'box that was supplied with a mismatched rear diff - causing the centre to sh*t itself within a fortnight. It's hardly surprising to hear that the remaining 752 bits have failed to deal with 350bhp for too long.
See here, here and here.
So, not so much an example of Subaru gearboxes being made of cheese as someone blundering forward without listening to advice, and chucking a load of good money after bad. Makes one wonder what the point of popping up here asking questions is when you're going to ignore the answers and carry on anyway. Still, at least it's an example to everyone else.

i keep saying in threads the two different coded 5 speed gearbox are pretty much the same strength but people seem to want to say they arn't.
think this kinda proves a point though dunnit.
after 300/300 your are puishing it but unless you miss a gearchange at the wrong time should be ok, 350/350 and your on borrowed time. there is the oddball that gets away with it, but its an oddball.
mine blew at 260/280, not managed to break, touch wood (pats head), my pgg box yet

Im getting a 754 built by API, and will be running I guess 330/330, so we will wait and see, but having spent too much time discussin, I was pretty sure that there is a difference.

Hi guys,
Hi have a type R running on a version 3 STI engine and wiring loom/harness and a version 5 type R box (ty754). The DCCD is disconnected as the loom and ecu did not support it. I got the gearbox from the UK. It had a few issues which i had to sort out - reverse was not engaging among other things. Anyway i got it sorted and fitted the box in the car and it ran very well. But now there is a grinding/grating noise coming from it. It does not sound high pitched like worn bearings though.
Mind you i removed the open center diff from the type R box and replaced it with a viscous center diff from a STI version 3 box seeing that i would not be able to use the DCCD.
Could it be that the viscous center diff is knackered as it is not an original part of the box. And hence would i be better off just putting in the open center diff even if i cant use the dccd fuction?
I have checked the ratios and everything checks out at 4.44.
Thanks,
Imran

Subaru gearboxes made of cheese ?? Hmmm,
You see, there is Emmenthal from Switzerland, which is quite hard.
Parmesan from Italy is extremely hard.
But Brie is useless; way too soft.

Mine is holding on at 350 lbs ft. I use my right foot hard on occassion, but am gentle with the left foot IYSWIM
I think it's more a case of Subaru driver's feet being made out of lead than the gearboxes being made out of cheese!
Get the car running lots more torque and then do drag starts and aggressive gear changes and, somethings gonna give; they just weren't designed for it.

Ns04, you treat you gearbox just like I do - never do standing starts.
I can change gear pretty quick WITHOUT yanking the gearstick as if my life depended on it too. Unless you're 1/4m'ing it, I just don't see the point in doing that. After all, it's bound to end in tears - and unnecessarily! - sooner or later.
