FD gear box and high rpm shifting

[colum]

good luck with liberty\'s customer service, its done when its done and you cannot speed things up

still waiting for a set of drop gears and a motorplate (6months and counting)

I would be up one for one set, when it comes to placing an order Grant. I am already working on a gearbox upgrade....So please keep me posted....

Iv heard they\'re slow. Lol. But f they can possible supply the bits and get the gear boxes rebuilt here then it might work out better. I\'m really just trying to find a good solution for everyone and share any info I come up with. Seen as there isn\'t a good source of info for people to find easily I want to do the leg work myself and have all the info in one place and easily searchable on here.

A lot of people can not afford a T56 etc such as myself so for under £1,000 it seems like the best option for a more reliable oxidized stock box.

Also with the HKS box being not only expensive, but also the scarcity of parts available to recon them people aren\'t willing to use them. Quaife is another option but then again its expensive.

I looked into this Liberty option a few years, it be fine up to 650hp, after that it will break the case or the main shaft, spoken to a few guys that run this mod, in terms of circuit racing this option is fine. I think for drag racing if you looking for more then 650 then go for a proper dog box eg Gforce etc

Oh yeah good luck when getting stuff done, few guys in the states have to wait for a few months turn around.

Do you need to change the rear end around if you want to run a Gforce t56 or can you get away with just a different prop?.

[BlitzBoy]

I was not talking about the Gforce t56 btw, I was talking about the clutch assisted GF5R box, I think you specify which car you have, they provide you with a yoke and then you make your own custom prop I should imagine probably get your existing one modified

I only want a consistent reliable 10/maybe 9 second car. That box is way too much. Nice though.

What do you think too a stock modified box coping with... Let\'s say a 75hp wet shot of nitrous? That stuff is amazeballs.

consistantly?
from experience... high to mid 10\'s

you can run the numbers with fd and t2 boxes (some as far down as high 8\'s) but after 3 or 4 passes, they like to crap out

chris seemed to do well on the rx8 box for a few years running multiple high to mid 9\'s

That\'s impressive stuff, I guess running low weight in the car helps prolong the life of the box as there is less mass too get moving. My car should be sub 1,000 kg, in know this as another rx4 iv been in, no turbo but had a full roll cage weighed 960kg full tank of petrol too. Doors still complete with door cards etc, and I can tell you this rx4 doors are heavy, so is the bonnet

got this reply from them.

Grant,
 
We do offer an upgraded main shaft for the Rx7, as well as the faceplate modification if you feel it will be applicable. The faceplate modification will allow you to shift at high RPM\'s without relying on the brass blocking rings to function properly. We can also perform a cryogenic treatment, thermal stabilization, and shot peen in order to add strength to the gear set. It really depends on what results you\'re looking for as to what I would recommend. If you\'d like you can contact Paul at (313)278-4040 to speak to him directly for more information.
 
Thanks,
Rocko Khoury
 

So I will try get in touch with them and see what costs are etc. Just need to find out what time difference is and call them when it\'s reasonable for them.
