Hi all,

I'm aware most will say ditch it for a mtx box, being seeing as I already have one bolted to the car I wanted to know the safest limit (if there is such a thing) on one of these boxes.

What has been the lowest/highest bhp/psi amount that a box has failed on?

I'm not chasing big numbers on my car,under 300brake is fine and more than enough for me.

cheers peeps

Cash it in as quick as you can!

my honest theory is, if the bc/ib5 could be miraculously made really bullet proof strong, then why did ford design another gearbag for the mandildo and higher powered escorts and foci? The answer is because they could not do anything with the bc/ib5.

im using the same box as stu collins and its still going strong, did 300+ on the rollers the other day.

saying that, it does worry me how much longer it will last?

chaffe

How much warranty did you get with it?

What he said.

Sell it and use the money to help fund an MTX conversion. No point crossing your fingers and blowing it to bits, losing any worth it might have had and then having to fork out to convert to a better box.

the VW boys have the exact same problems with the o2a "crumble box", they are weak and also have a small clutch, the only solution considered with them is to upgrade to an o2J or o2m box, they have all the problems associated with an mtx conversion, making mounts, changing the gearshift, flywheel, driveshafts have to be changed, but once done its fit and forget basically. It seems more and more people are getting this idea in the ford scene now, maybe due to engines making more and more power.

none, i bought it off my boss, who had run it for some time on his zvh and ive been running it for just over 2 years.

bezo

really? what box are you running now?

d'oh, I think running my current set up i'm going to fine (under 250) but I think I will eventually ditch it for the mtx

i did my first mtx conversion for Ł50 (the price of the gearbox) well worth it. I made the engine mounts and modified the inner wing myself, modified mk5 escort shafts at work to take mk outer cv joints, and made a custom linkage by welding a mk4 and mk5 escort one together.

My CTS Stage 1 box is still going strong after 7 years of thrashes an dtrack days with 260bhp and similar torque. My chosen tuner also says I drive like an animal too

bezo

so there are some BC boxes out there that do stand up abuse

chaffe

I wouldnt abuse one
