Sierras are hard to come by, alternatives?
Ninehigh - 9/2/09 at 09:50 PM

Not seen a Sierra for sale round here since shortly after coming to this site, does anyone know if they're common in dismantler's places or if there's a common alternative i.e. could I extend a BMW/MX5/Merc one?

Have you tried searching for p100 's? sometimes they slip by the casual browser.

Sierra's are unsurprisingly, due to their age, getting in short supply. I am surprised that manufactures continue to base their kits on them and don't move on to the latter model cars for doners such as the Mondeo etc.

i think they are front wheel drive so no good!

Mid engined car with front wheel drive donor.
The writing's only been on the wall since 1993 (the year the Mondeo replaced the Sierra).

Build a Sylva Riot and be done with it.

granada's and scorpio's can be a bit easier to find, but it wound be nice if more kits moved on to newer donors


Ninehigh - 10/2/09 at 08:29 AM

So pretty much any rear axle will fit?

It is a problem basing cars on increasingly rare donors, but surely there's another out there that is just about the same width...

It all comes down to which design you follow / kit you buy and how much you want to alter it to suit different running gear

a sierra with 7"diff, should be the easiest - other donors might need you to be a bit more creative


Ninehigh - 10/2/09 at 08:46 AM

Ok when I said `fit`I meant being the same width... How wide is the Sierra diff anyway?


mr henderson - 10/2/09 at 09:21 AM

Are you seriously trying to find a different donor because you can't find a Sierra, or do you just fancy building something different.

I can guarantee you it will be a lot easier to find a Sierra and base your build on that than it will be to base your build on a different donor, unless you use a kit such as Westfield or MNR do based on the MX5.

If you are planning to build your own chassis then using any donor other than a Sierra is going to take a long time and be more expensive.

Better to drive 500 miles to find a Sierra than start a scratch build based on a different car.

There not that rare, thousands still on the road and a quick look at ebay theres 45 just searching for Sierra. Some are mega money Cosworths but there are some very cheap ones including a couple of 4x4's.


Ninehigh - 10/2/09 at 09:37 AM

Actually I was more asking if I could just get the diff really?

I expect so. They come up on here sometimes.

there are always some on ebay linky
but the prices can be silly sometimes


btw there are 2 sizes of sierra diff 7" and 7.5" (the 7.5" is quite a bit bigger / wider / heavier)

the 7" is the one in most sierra's and is the one most kits are built for (although some kits like the dax's can have either without any mods)

the 7.5" is the most common in the granada's and scorpios, but it depends on age, model, engine and what ford had in the parts bin

Ninehigh - 10/2/09 at 10:56 AM

Ah of course the diff doesn't include axles...


mcerd1 - 10/2/09 at 11:25 AM

so you'll need hubs and driveshafts too then (also on ebay or sometimes on here)
there are 3 types (to suit different diff versions) push-in, bolt-on and cossie 2wd (i.e. bigger bolt-on)



it is possible to get all the bits you need seperatly, but it will probably cost more

mcerd1 - 10/2/09 at 11:27 AM

also some of the BEC lot were using freelander rear axles (lighter than sierra)

very different transit bolt pattern


Ninehigh - 10/2/09 at 01:28 PM

I'd rather it be more expensive than have it sat in the garage rotting because I can't get some rusted piece off


mr henderson - 10/2/09 at 01:45 PM

I don't think you are making yourself very clear.

Is it the entirerear end you want (with subframe), or a diff, or just the diff and driveshalfts? Or the hubs as well? What about the rear suspension (remember most rwd cars have struts)

If you can say a bit more about what you have in mind the answers might be more helpful

mcerd1 - 10/2/09 at 03:01 PM

Ninehigh - a few basic questions about your build to help narrow it down (based on the above and some of your other posts)

* which chassis are you going to use ?
custom (your own design)
old haynes book - Ron Champion (for £250.....)
new haynes book - Chris Gibbs (on a budget)
or a variation of one of the book designs

*what engine do you want to use / are you using ?

*is it mostly for road or track use ?

Ninehigh - 10/2/09 at 04:39 PM

Ok, I'm basing it on the new book, but I'm space and cash restricted so my plan is instead of having a donor rotting in the way for a few years while I'm saving up for some new part I planned on scrapping the whole donor thing and buying bits as and when I can. The setup is pretty much as the book only with a new zetec engine and it'll be pretty much exclusively for road use.

Hope that's better


mcerd1 - 10/2/09 at 05:12 PM

could you not get a donor, strip it over a week or two then get rid of the shell ?


Ninehigh - 10/2/09 at 05:35 PM

Not really, knowing me that week or two will extend into months... Also I'm after as new as possible parts because the main problem I've had with fixing cars is rusted parts

This is a very expensive way of building a car though, and there are all sorts of useful odds and ends that you'd get from a donor that are difficult to buy.


Ninehigh - 10/2/09 at 06:54 PM

In that case how important is the shell itself? I gather I can recycle a good chunk of the panels I'm just thinking can I slice it to bits?

Plus the other side of that idea is that yeah it's more expensive in the long run but having £600-1500 for a car now is a LOT of money


Meeerrrk - 10/2/09 at 08:54 PM

personal preferance would be toward mx5 i think


Ninehigh - 11/2/09 at 08:12 AM

Yeah mx5 is smaller, plus I could nick the roof off it
