would u use the same shafts as u do for zetec turbo conversions, when not using rs box?

ST170 spline is one of a kind mate.

You need the custom shafts made to measure and fit your application.

Dave mac props make the shafts which will handle any power you put at it.

£250 each shaft and made to measure. Yoiu need to supply the measurement

RAT8OY

Fuckin hell £500!

I dont doubt most places will try that on but in reality you just need the correct grade and diameter bar and a good engineering firm that can cut the spline to copy the standard ones you can supply for them to copy!

TBH I will have custom shafts made up when I go equal length but at the moment I have cut, sleeved and balanced items, which may be a cheaper solution. If your on a budget.

No doubt though, that Luke is talking best of the best no budget limitations!

The shafts i have made are same spec grade material as F1 cars and allow torsional twist. This allows them to take 1000hp.

But yes its not the cheapest but by no means the dearest i was quoted £600 to cut and weld my current ones and be re baleneced.

SO WHATS INVOLVED IN FITING AN ST170 (turbo'd) ENGINE AND BOX INTO A S2? CHEERS

anodised

new gear box mount
new drive shafts
new rear gear box mount
new engine mount
new gear link
fitting a pedal box cause the gear box hits the brake
plus hydraulic clutch

plus a few more bits

so how much does that roughly cost?

anodised

gear box is £200-300
shafts £500-600
gear link + cables new £174 + 64 from ford
pedal box with hydraulic clutch about £300 (talk to tony (NUTS RuS)

then its just mounting it so find a focus gear box mount and cut it and weld it in

you also have to re route ur brake lines and the st clutch is not that much good for big power turbo engines

sitech racing can help he has an escort with a 6 speed box in
m4dyeti has fitted the 6 speed box
and i have most of the parts and im about to start fitting it

mercurygreyrsturbo

iTrader: (-1)

so is it worth doing?

anodised

i hear the box is very strong its got 6 gears its newer it can handle big power

other options are rs turbo or cts2+ box or mtx75 or the st box

i would say yes if ur dropping the st170 turbo in

Thats what i was thinking, i want to make over 300bhp with the st170 engine, i hear that the standard top end is good for 400bhp, any advise or knowledge would be a great help. thanks for the advise so far.

Your going to need to change the flywheel and clutch also as the st runs a dual mass flywheel/clutch set up.

iTrader: (-1)

where can i get replacements?

jessie_rs

i wouldn like to run a cts+ even when you have them shot peened they still cant take the torque and wouldn last long with all torque from st turbo engine 1200 for a box that needs rebuilding everyyear

anodised

sitech (sas) i think he is called on can help with a fly wheel and clutch

and if you read m4dyeti rebuild in fast ford last month it tells you about he fly wheel or ask him on here

other than that i cant really help cause i aint on this part yet sorry

what gear linkage do i need? is it just a focus one or does it have to be an st170 linkage?

anodised

has to be st 170 brand new from ford its £170 for the stick and £60 for the cables

but cause they are cables its easier to fit than the mkx75 gearlink

ive found mounting the gear stick on top works better than fitting from under the car then all you have to do is cut a hole near the front for the cables to go to the box

im going out to my garage 2moro will try and take some pics of what i mean

Luca

As above fit the assembely in the car and posistion whee you feel comfortable then the cables come with a rubber guide/gromit which needs to go through tunnel/floor area.

No trimming is needed just route so there are no tight bends etc.

Simply clip on the box and you have 6 gears which feel very posisitive.

The next mission is the driveshafts ive got the shafts made now i just need to solve the rear halfshaft bearing mount.

A friend of mine that has an Rs turbo engine with an st170 box fitted a Golf turbo diesel shafts that I think have the same spline at one side and he custumed the other side. Ask Zoqdi racing in Malta who did the conversion.
