GC8 gearbox
 

hi guys and gals
i am hoping you guys can help me out bug time here. Ok so my problem is that i have a 3.99 5 speed box and i have chucked 3rd gear. So my question is, I would like to install a 6 speed what would i have to do to complete this and where would i go to get the gear? If it is too much work my next choice is getting a dog box and where would i purchase this?


Thank you guys for you time and help

Dog box gear kit, shift forks etc are purchased through Albins gears, Pfitzner gears, Modena Engineering among others. Then they are installed in your existing case with your existing transfer gears, Final drive gears and diffs. 5 speeds run to about $8000 by the time you set it all up. 6 speed dogbox is approx double. Essential for racing but not ideal for street use and unable to be engineered for street use (in W.A. at least)

6 Speed synchro would be a better option for street use. There's a number of wreckers and importers that sell them, or scour the forums. I no longer sell them unless I do the whole job of installing it as well.

would it be worth putting a 6 speed synchro in instead of a original 5 speed synchro or the 5 speed dog box? ive only heard that 6 speed boxes are stronger then the 5 speed boxes

What are the plans for the car?
If racing/tracking at all, (and you plan on keeping the car for a while) then yes I would. Rather than continue to possibly break the 5 speed over and over.

If just street driving, then depends how deep your pockets are.

The cost of the 6 speed swap (box, matching diff, clutch, labour etc) is essentially half the cost of a whole GC8. Not worth it for just a street car IMO. Hence why I haven't bothered...

You are unlikely to break the 6 speed if that's what you are asking? People run 500hp+ without any dramas.

Not you too :( i did my second 5er 2 months ago i got a 6 speed contact kris at rising sun subaru he gave me a killer price

Yer this is my second box going on third where is rising sun Subaru Jacob and what gear ratio box you get and did you have to change anything else to get the 6er in Jacob

how retarded are you at changing gears?

cheers forde i wasn't actually changing gears going from 50kms then started to go faster then bang kind of a shitty way to go would of been better to let go doing something and i couldn't be any further away from home too and the first one went when the front diff just gave up on my misses "apparently"

Ok I've chosen what I want to do with the car and was wondering what is required to do a 6 speed conversion. any help would be greatly appreciated.
