Hi,

i have recently stripped 5th gear in my RA box, and am looking for a replacement.

I have also discovered a pool of gear oil on my Garage floor, so guess the 40 miles I drove the car home in 4th done some extra damage to the casing.

I have been unable to locate another early RA box, but stumbled across a Version 4 STI TYPE R DCCD gearbox, rear diff ECU, switch and dash. but the wiring is missing.

I have found through searching that i can get a Manual controller for $170
so I plan to sell the dash and ECU and get the controller, but use the original switch.

is their anything else I will need to do or get? will my drive shafts fit etc?

and is this my best option, I cannot afford the 6 speed or PPG.
I aim to do some Drag strip, and Track with the car, and a bit of off road drifting.

I have also been told with the Manual controller, I can add in an extra switch, to the handbrake wire, and earth the other end... thus at the flick of a switch giving me full power to the rear?

is this correct?

Any advice would be appreciated.

Thanks
Derek

 

i have a freshly built gearbox that should pop straightinto your ra mate bought it for mine but sold the car its the 252 casing with 254 internals the stronger uk ones and the box was setup by Kenny brown who does the race cars so is spot on sold my car so this why this one for sale. Greig

 

Hi Greig,

I had just read your Add.

would you know the ratio's used in the box?

I would ideally prefer to keep the RA ratio's or else move up to a DCCD.

 

not sure mate ill ask archie final drive if i have this right is 3.9 same as ra`s\
ill see what else i can find out

 

The 93 - 94 Ra eg. min has a 4.11 final Drive.

Although i would need to know the Final Drive, i would also like to know the actual gear ratio's too.

Thanks
Derek

 

A TY755VN1AA will go straight in.

But it has the same ratios as

TY752VB3FA - 1st 3.454, 2nd 2.062, 3rd 1.448, 4th 1.088, 5th 0.825, rev 3.416

Guess it depends if you want to keep your short ratios.
