MY 03 WRX is running over 300 ftlbs of torque and this seems to have fooked my gearbox up. Ran hard in first gear going up hill, quick change to second and a very loud bang... all I get is crunching from the gearbox now and the gear lever is very very hard to move if at all.

So, if anyone has a new or used gearbox, please can you contact me as a matter of ugency please! my email is: mike@eclipselegal.co.uk.

Many Thanks!

Here I go again.....

Give David a shout Welcome to the API website

Cheers Rob, I will be contacting all the major Scooby garages tomorrow first thing, just thought I would ask around the community to see if there are any knocking around.

Will the diffs be affected? And will a 6 speed be the preferred choice or should I stick with the 5?

[MikeyB]

Does anyone know what this is likely to cost me?

give API a ring

very rought cost is 3k for a built ppg 5 speed ( super strong )
about 2300 for a second hand sti 6 speed ( strong )

diff will be the same with both if you stick to uk spec gear boxes

I wouldnt bother with another std wrx 5 speed but im sure API will set you strieght

Might be selling this little lot if your interested:

I opted for a PPG set in my 02 WRX, supplied and built by API.

Super strong and whines like a bitch

IIRC £795 will buy you a rebuilt standard box also

LOL, fantastic.
Could you possibly post up or send me a sound/video clip so i could actually hear what the PPG sounds like please?

[MikeyB]

Does anyone know the weight difference between a WRX geabox and an STI for the model 2003 WRX?

Also, how much torque can the STI box handle safely?

pslewis

Got the Wifes Micras Gearbox fixed by a Transmission Specialist - cost £86! (I removed it and re-fitted it)

New Input Shaft Bearing and Oil Feed ...... all boxes are pretty much the same

Don't pay silly money, find a reliable local gearbox company operating out of some industrial unit and you will be amazed at how cheap gearboxes actually are to fix .......... even a rebuilt box for an Impreza shouldn't cost more than £750 (thats removed, new clutch, and refitted) - all the parts are readily available.

Like I've said before .......... it is just a car - NOTHING SPECIAL about the Engineering!!!

[MikeyB]

I've just spoke to API and for a 6 speed UK box I'm looking at £1800 + vat fitted...

There's no point putting in another 5 speed box as I'm sure I'd have that in pieces sonner rather than later...

Is there much point in stretching to a PPG box, or would that be overkill on a 334/310 Impreza?

Ignoring the weight (half the weight of your girlfriend /wife probably) I would choose the 6 speeder, UK or Jap spec and have API fit it as they are a bitch without ramps etc.
The change is smooth, they are super strong (400 lbft etc torque ) and the value of the car will increase!
A fit and forget option.

For performance the ppg is the best, but the whine is there even in helical form.

At 2K ish is a deal even if it brings a tear right now.

There is plenty on here running over 400.

Not heard of any giving up yet. Will take a while to get used to the ratios and constantly changing gear it seems, but that's half the fun of being in an "involving" drive.

Pete, you're correct, apart from the fact that some spares for the 'box maybe quite expensive. Labour shoud be about the same for all gearboxes though!

[MikeyB]

Thanks for all the advice. I'm just toying around with the option for 6 speed, or 5 speed PPG..... Not too much difference in price, so which would you go for, is the whine too annoying?

Cookstar, did you get the straight tooth or the other one?

Cookies, Sorry, MR Cook's gearbox is straight cut synchro. Mike, you need helical synchro if you are thinking of PPG. You won't need the strength of the straight cut at your power levels and the whine of the straight is sufficient to drive you nuts if you don't love it as soon as you hear it.

Don't forget that anything bought or done here is warranted.

As above straight cut for me.

The noise is great (well i like it) if i get fed up of it i just give a passenenger ride, the screams normally drownd it out

@ screams

A local lad has a (I think) straight cut gearset in his gearbox and it sounds ficking great. I want one when funds allow

MaDaSS

Is the helical cut box quiet then? How much torque are they good for in 5 speed set up? Ta

[MikeyB]

Think I'll be opting for a 6 speed down to funds... just can't stretch the extra £800, or should I.....

I drove a 5 speed helical synchro PPG car to and from the MOT test centre and didn't even know it was a PPG. That's what convinced me that these are GOOD and not noisy.

Read the PPG website for claims about power and torque capability. The helical will not be as strong as straight cut, but under most circumstances will be fine as a daily driver /track /1/4 mile car.

Dog engagement is not road car equipment, it is pure race car stuff.

David APi

MaDaSS

Thanks for the info
PPG website makes no claims as to torque or power capability for the helical/synchro setup at all, so thats no help.
I would have thought this should be listed surely so ppl know what it will take? Anyway, not to worry.
Like most ppl, i wont even consider changing unless i break the one i have.

PPG does say the helical has slightly more noise than factory box, but being as you have driven one and could not tell then that is good enough for me! lol.

MaDaSS

For me personally i would try to find the extra and get a 5 speed helical cut synchro box via API.
As David states above, he has driven one of these and didnt notice any more noise than around normal with it.
What with that and the fact it would obviously be able to take a hammering on the road anyway, would be a good option i think
You aint scrimped on the rest of your car, so why compromise on the gearbox?
Have a read on the PPG webby, it explains all in nice simple terms for ppl like me! LOL.
