has anyone got a guide for a st170 gearbox into an escort i have done a search but cant find one.
thanks matt c

 

simon from sitech racing has a st170 6 speed box in his motor.

 

there is not a guide that i know of im fitting one at the min

you will need

st170 gearbox
st gear stick and cables
focus gear box mount
new drive shafts
pedal box cause the old brakes hit the st gear changer
and if you going for more than 170bhp a new fly wheel and clutch set up

as you see in the pic you will have to weld in the new mount on the inner wing
also one at the rear




ive also fitted my gear link aswell but no pics as yet

 

im going full zetec turbo so am aiming for 300+ you say new flywheel and clutch, i can understand the clutch but why the flywheel, what pedal box (where from or what out of). help and pics are much appretiated

 

what he said

 

the fly/clutch is a duel mass thing which dont like anything over 170bhp so im told

the pedal box need to have a hydraulic clutch on it also the gear selector on the

gearbox hits the old brake servo

comp brake are making my pedal box pm nuts rus on here

sas on here has a 6 speed box in already he also sells the fly wheel

the gear link is easy remove the old one and bolt the st one on top cut a hole at the front of the tunnel run the cables through the hole thats it

here are some people who have done the 6 speed box

Little bit of info on my resto thread.

Simon.

 

dont forget it's very close ratio. 6th is lower geared than the BC 5th.

 

Hi Rick, not convinsed about that fact.
When I did the Redline FWD Thrash my car did 164.5 in 6th at 6200 on 205 40 17

Simon

 

Is it not something that's easy to prove? Surely you know the ratio's?

 

Looking at a 190+ with 8200 rev limit..

 

what pedal box are people using link would help thanks
