Imagine paying 20k for a car and that happening...
So, need to keep an eye out for a box, probably worth doing it now just in case one isn't available when i need it.

Some of the cars there are worth six figures. The carbon wheels on the GT3 are worth more than my car.

• WRX Type RA
Race Altered is a lighter weight Impreza generally they come without underseal, radio-cassette, electric windows & sound deadening materials in the cabin. The RA comes with a closed deck block, shorter gearing & rally flap style roof vent.

Stripped the gearbox today, very simple to work on

Yeah that's not gonna work too well like that

That's a proper job.

Baz82

lol new box coming tomorrow

Kwik

iTrader: (10)

What box have you gone for Baz if you don't mind me asking?

smithy86

after reading all that im none the wiser lol...i suppose they all have pros and cons.

Sprint Chief

If Baz is sticking with his original plan, I believe he is going for the gearbox from a 2001 Legacy twin turbo. The 99/00 twin turbo legacies shared the same gearbox as the 99/00 impreza WRX saloon and STi; I suspect the 01 legacy twin turbo will be almost identical.

These boxes are supposed to be a bit stronger, with many people on the P1 forum running healthy 400bhp through them with few reported problems. That's on a 2 litre though, with 2 litre torque - Baz is putting more torque through it with the 2.5 litre motor.

It will be interesting to see how it all copes!

Baz82

Thats the plan yes I have the boxes out of both cars , just have to remove the diffs now and fit everything. I dont I have more than 350 torque being honest . For the price I paid I'll take a chance on the legacy TY754VBBBA

iTrader: (10)

It will be insteresting to see how it copes Baz, what did you pay?

Essexdon

Good read, currently waiting for the inevitable bang in my 95 WRX box to go.

mickywrx

iTrader: (29)

I've done 2 TY752 boxes, the noise when you strip second gear is quite impressive.

Been running a TY754VN1AA box, for a few years now with no issues.

Not all gearboxes are the same though, just like Impreza's.

Baz82

It will indeed , I paid €100 for the box and diff and I am breaking and storing the car they came from for a mate , good deal I reckon.

I had to change over the ring gear from the legacy 4.1 diff and fit it to the Impreza diff today and fitted it to the legacy casing so I have a matched Box and rear diff and no problems with shafts. Thanks to David in Api for the advice through email.

So basically the 98 sti has a 4.4 final drive and the Legacy a 4.1, plan was to fit the box and whole rear diff and shaft from the legacy. That clearly wasnt going to work as the shafts are slight longer and not as thick as the Impreza's.
To sort the Final drive and shaft problem the solution was to remove the leggy's rear diff ring gear (4.1) over to the Impreza's diff and fit the diff in the leggy's diff casing so the pinion match the ring gear. Thats all done now all I have to do is drop the diff into somewhere to set the backlash clearance so that the diff is not overly noisey, or wear prematurely.
He's a a few pics:

New Box


Stripping the diffs legacy on the left and wagon's on the right


Legacy Diff


Impreza diff


Ring gear from impreza


Ring gear removed from the Impreza diff


Impreza ring gear with 40:9 Stamped into it , divide 9 into 40 you get 4.44


Legacy Ring gear with 37:9 stamped into it, divide 9 into 37 you get 4.11


Impreza diff with legacy ring gear fitted


Diff then fitted to leggy casing

nice flip plops with socks in your pic

Baz82

Lol cheers I'll tell my mother you like them

craigo

iTrader: (1)

deepest apologies...... to mum

Baz82

She was just greeting the new garage lodger

Sprint Chief

Wow Baz good job you played safe and swapped them over. I double checked the list and the MY00 legacy is 4.44, the MY01 is actually not listed... oops!

Nice photo record though, very useful

Does the shift seem different? Are they interchangeable?

Baz82

Yes the 01 has a 4.11 Final drive, suits me being honest always thought the 2.5 could use longer ratios.

The shifter seems the same in both nothing to be done there I reckon.

I dropped the diff off today to get the backlash checked should get the box in tomorrow and collect the diff then tomorrow evening

Baz82

The wagons back on the road , feels great, happy it all worked out . 120km/h (motorway speed in Ireland) is 3000rpm as apposed to 3250rpm

*CRUNCH! BANG!*

#dum de dum de dum...#

Sprint Chief

Good stuff Baz, be interesting to find out how that handles the torque. Hopefully the gearset is the same as the v5/v6 STi ones which plenty of other people (e.g. P1 crowd) are running higher power and torque on.

Sounds a bit calmer than my RA which is just coming up to 4krpm at UK motorway speeds...

Another interesting claim I wasn't aware of, read on another forum. Allegedly early 6-speed boxes have a design flaw that causes 4th/5th/6th synchros to fail after a period of time. I'm assured that it is a cheap fix, but I think that "cheap" in this sense means "cheap compared to the price of a six speed gearbox".

If you're getting a six-speed gearbox, make sure it is either a later model box (not sure when the changeover is or what gearbox code yet) or an early one which has had the synchros repaired (the replacement part is redesigned and should fix the problem). Otherwise you might be paying more for a box which should have no further costs... only to find out you have to pay out as much as a 5 speed box again to repair the design flaw

Usual caveats apply here to info found on the internet etc.

^ It is indeed prudent to go for a blob box yes

I bought a blob box for my other classic but in my '95 classic the bug box runs fine tbh. If you look, generally bug boxes are the cheapest to buy. Broadly speaking £1000-£1500 for a bug box £1500-£2000 for a blob box and Hawkboxes £2k+... Exceptions apply but this is generally the trend I've noticed

Baz82

Shhhhhh its grand I only paid €100 for the box

I reckon it will do me fine if I stay away from the track
