Well you have English axles which are the standard axels on most mk1/2 escorts. (they are the type where the diff comes out the front) You can pick up an LSD for them for £400 (brand new!) and there are differant types to choose from! Loads of ratios are avalible and they deserve more credit then they get relly. They are the weakest of the coices but then again you don't hear of them braking that often! i think they are ok for x-flows and pintos but for zetecs and cossies over 200bhp ish you should move to an atlas
Theres several types of atlas axel. They all are salisbury type where the diff comes out the back. The standard atlas was fitted to later capris so is easy to come by. The 2.8i capri had a LSD as standard so this is the cheapest option. However I'm not sure if it is as good as an aftermarket type and i think some people do modifications to make it more harsh!
The baby atlas it just a normal atlas thats been shortened to the same width as the standard english axle. Thy used them on escort rally cars and the like. They are quite rare and fetch a very high price! For one of my escorts we are attualy shortening a standard atlas to the same with as the baby atlas as its cheaper!

As slater says english axles are a good bet and generally pretty strong. I would recommend a new LSD for one unless you know it has been rebuilt. They do have a weak point though and that is that the endplates are prone to breakage when driven hard (even just with a standard pinto). Easy upgrade is to buy one made from EN24 and these cost less than £100. I know a few people using these in autotest cars and in fairly powerful pinto escorts they get around a year out of halfshafts before they twist/break. Standard atlas axles sell for peanuts but if its got an LSD in then you are looking at £300-500 and in all honesty you would need to plan for a rebuild. The standard ford diff has very little preload and once it has a few miles on drives similar to an open diff. A set of clutch plates costs around £120 and they are not to bad to rebuild. Or you can buy one brand new for £450ish. For a starlet your best bet would probably be an english just due to the width problem, unless you can find a cheap bare baby atlas casing. Another possibility would be a marina/ital axle. These are quite a bit lighter than an english, and as they were used in live axled caterhams LSD`s are easy to get hold off.

great i appreciate all your info loads cheers!! ahh i don't think il break it, I'm only running a mildly tuned 1500 on twin 40's cam etc. looks like an english so for me. my next question is, will it be easy enough to get someone to restud the axles to 4X114.3 (rwd toyota fitment) i don't wanna have to buy two new superlites also, i know probably no one here has done this, but how easy do you reckon it will be to hook up my brakes/handbrake etc? i will have to cut off all my mounts and weld them onto the english in the eact smae position. do english axles come standard with panhard rod?? as my car has none its has an angled bar four link setup cheers for the help much appreciated!!

They didnt have a panhard rod as standard. Most just had leaf spring mounts and some RS ones had mounts for radius arms aswell but other than that they are mount free!

Standard english handbrake mechanism should be easy to attach to any car. Just needs a single cable going to it.
Panhard rod kits are available for english axles and pretty cheap but as its not going on an escort you may need to shorten it or modify the body mount.
Plenty of places should be able to modify the halfshafts to suit a toyota stud pattern, just contact a local engineering place. Shouldnt cost much or take long.

the trans X slipper is probably the best one.
but if you want most lock, well, then lock it ;D ;D
don't beleive the hype about them being 'that' strong, ive snapped the diff in mine and ive only got 86hp, and its a road car ;D ;D

power never broke anything. ive heard of nigh on 300bhp tubo cossie lumps still on english axels. although a good lump of low down torque and that'll be you going through halfshafts.

exellent thanks a million lads one last thing, whats the best type of plate LSD i can buy for it, ie most lock?? thanks!! Build it to suit. They all can give as much lock. I run a standard atlas LSD from a 2.8 capri. I bought it needing a rebuild and set it up so it is almost locked. You can also vary it slightly by using different oils. Standard LS oils have additives to aid slip of the clutch plates. EP80/90 don't have this and encourage more lock. I use a semi synthetic oil in my atlas and the way I have it set it is a little more progressive than a locked diff but still very tight. Gofasterpinch your right its not power outputs that damage the drive train it is torque coupled with grip. But as most people describe there engines state of tune with regards to their power outputs its easier to compare them that way. Generally (not always) most 4 cylinder cars in a moderate state of tune are going to have a torque figure (in lb/ft) similar to the bhp figure, and once you start talking mega power then the torque will generally taper off.
