JC5-145 Ratios

[neil a]

Does anyone have a list of the jc5-140 box ratios please ? I've had a look and can't find anything other than it was fitted to the 1.5dci clios.

Re: JC5-140 Ratios

Thanks alot going by those ratios and the low final drive , the speeds are way too low for what i need topping out at 102mph.

Sound like its more suited to a hill climber Neil.

Re: JC5-140 Ratios

Are you sure? Its FD is very long (it is the longest FD in the JC5 range). It's good for a diesel engine but not for a petrol engine IMO (except if you would like to get good mpg).

Re: JC5-140 Ratios

Sorry Yanoo I have just re read the PM and it is actualy a JC5-145 box not a 140 do you have the ratios for this box.
It has also been fitted with a 4.5 final drive, thats how i got the lower speed when working out the 140 box as with the standard FD it will do 140mph.

I tried hard looking for a 145. From a Laguna IIRC but couldn't find one.

Re: JC5-140 Ratios

Do you know what the gearing in them is ment to be like to as in is it fairly close ratio? I can't find the ratios for the 145 anywhere but have found a place listing that box so have emailed them.
