i am going to be running about 350 bhp what would be the best gearbox to use and does any one no where to get info on seem welding my s2 shell plz

 

hi, dont go mad on welding the shell----IT MUST FLEX!!!<<<IVE GOT MK2/1 DETAILS FOR MOTORSPORT GUSSETING ETC BUT UNSURE OF MK3/4S.
WHATS YOUR PLANS FOR THE ''PREPARED SHELL??????????

 

has to be a mtx75 very strong box in standard form ,failing that a cts stage two plus, but the bc box has to be rebuilt yearly especially if you are into top speed events and sprints, 350fbt or more then you are asking a lot of the bc box... everything about the mtx75 better bigger gear set, bearings, shafts etc. no one knows how much a mtx75 built to the same spec as the cts stage two can handle.. there will soon be an answer

Sean, just on initial inspection, I didn't think the MTX gears were actually any beefier, which is what is putting me off that conversion, considering how much it costs to do it.

 

dont forget the cutting of bodywork thats needed


this is all thats putting me off also

 

Box wise I have done over 5k on the Getrag 6 speed box from the focus st170, it not gone bang yet! Power is in excess of what you are lookin to run.

dont think that would be a problem, when cts have said their stage 2 pluss boxes will hold, if they dont.. deliverer it back and surly the would fix it

 

Sorry to hijack post...

how hard is the conversion for the getrag 6speed box?

The missus has an st170 and i love that box (i have a zetec in my s1)...

 

Basicly you need a ST170 flywheel and clutch, new drive shafts, hydraulic clutch (there is no prevision to go mechanical in the box), inner wing mount, torque reaction mount under the floor and the whole lever assy inc cables. You dont need to cut any metal off the car.

Is there a sequential shifter available for any of the Ford FWD gearboxes? Has anyone ever built one to their RST?

 

oooooooooooo now your talking


quaife and hewland do one, they come without a bellhousing so would need to get that made


these engines have been about long enough that im sure they have mould already for one

 

I'm more thinking of just a sequential type drum changer for a normal gearbox the ST170 6-speed or the MTX-75.

 

o im just getting over excited then

 

What sort of spec you got for 350bhp?

Is it still a 1.6?

any pictures of this simon?

also if you go for the st170 box i had a think about one of these

imagine a gearbox like a rally car with the push forward/pull back gear changes how cool would that be

 

Thanks alot

I take it the drive shafts need to be custom made??

Excuse my lack of knowledge but what is the torque reaction mount? How hard is it to incorporate to a s1?

If there is no need to start chopping away I take it the conversion can be done without needing the car booking into a bodyshop...

sorry for hijacking post *again*

 

the st170 gearbox holes for the starter motor are differant to the zetec & cvh gearbox ones, but they would work with a bit of modification

 

You do have to fabricate an inner wing gearbox mount to suspend the gearbox and the torque reaction mount again does have to be welded on to the floor.
Currently dont have any pics.

Its being done mate

 

Pics... pics... pics...

Really fancy the conversion

If you could pm them that'd be great
