Hoping someone can point me in the right direction here. My gearbox has bit the dust and I've been looking at my options, I've seen a cheap iB5 gearbox from a KA, if I was to fit this box how do I go about converting my car to hydraulic clutch, does the KA release bearing marry up with the RS Turbo pressure plate, I've looked for guides on here but they all seem to use the RS Turbo release arm with a bolt on slave cylinder.
Cheers

 

I'm sure Karlos G used the KA gearbox with its integral slave cylinder, have you read the entire thread he wrote?

 

Cheers mate. I read the thread and I could only see the bolt on slave. I'll drop him a PM

 

Page 3 0r 4 he mentions he is now on a sport ka box.

 

The sport ka box is not the one to use, requires too much modification really and the ratio's are terrible (too close).
If you are CVH you need a front starter IB5 cable clutch box from am MK5 escort or Escort diesel van (long ratio's if you go diesel though) for direct fitment.
If you are ZT then the early KA 1.3 box (Pre 2002) and fit a hydraulic master cylinder to your pedal (hole in bulkhead, modify pedal to take clevis pin, run pipe to slave).

 

Can you not use the early ka box with a cvh karlos ?

ive got a lsd box in my fiesta which is shagged so wanted to go ib5.

Was as originally looking for a sport ka box ( I'm not running big power - so close ratios is fine.

Im still on a cvh. But might go zvh black top over Xmas

 

Early KA box is rear starter.

 

Yeah as Stu says, it won't fit.
You'll also need to modify the gearbox cradle to correct the gearbox bell housing rotation if you use a Sport Ka box, but I really wouldn't, you'll be doing 70mph at 4000rpm+ and wheel spinning everywhere in the lower gears!

 

What about an early ka box on a cvh then ?

In your earlier post karlos- you said early ka box for a zt---- Will it not work with a cvh?

Cheers

 

Oh I see. I need front starter. Are non of the ka boxs front starter ?

 

Yeah ZT is rear starter.
Only the Sport Ka but that has terrible ratio's and rotates the engine about 15 degree's.

 

Ka 1.3 box from 53 plate onward is front starter and not terrible ratios. The sportka had awful gearing to make the 0-60 etc time better.

 

The ones from Duratec KA's are too long (5th gear casing sticks out way further) and means cutting the inner wing.
