Build or Buy ?
I'm a competent welder, work close to a steel stockholder and I own a large Mig welder. This is my first attempt at this kind of project. I intend to
use a sierra as a donor car. Should I purchase a chassis frame or attempt one myself. Is it easy to modify the locost chassis as described in Ron
Champion's book (which I have yet to purchase) to accept the Sierra' running gear and IRS.

Its not as dificult as it loks to build a chassis,there are photos in the archives and some drawings around,no doubt someone will tell you where they
are,just do it!

If you're worried about fitting IRS from the Sierra, why not go De Dion. MK still sell the necessarys for about 100 quid.
Uses similar mountings to live axle.

I would really suggest building it, it's so satisfying (although I have built mine to the book).
btw, my website has been updated with pics of the donor escort and our method of removal.

Sierra seems to me one of the easiest and cheapest options, what do you suggest?

To be honest build or buy should be a foregone conclusion
I can understand anyone who has never built a car before having some reservations, but you'll have a flying start. Save your cash for stuff you
can't make
All IMO of course

Having seen an MK chassis it makes me depressed I could never do one that good.
However, welding up the chassis is probably one of the most enjoyable bits of the build. it all gets slower after that point!
Unless you are gonna race it, dont get obsessed with an independent rear end. Using a live rear axle saves a shyte load of time and allows you to
follow the book. AFAIK there are no definitive plans for a independent locost chassis....might be wrong.
If you want to see how a sierra rear end fits, look at a robin hood - if you want a built chassis, then build a hood as it uses that rear end.....
The sierra rear is BIG and would take a shed load of mods to fit. Get it off the car, stare at it for a while, and rethink!

Yeh,... stick with a Cortina/Escort, it's simpler and there's still plenty of them around cheap. Save the cash for a bike engine like me!!!

Thanks for the advice..I'm gonna build. Live axles however seem rather scace in my neck of the woods . There is, however a p100 that I can maybe get
my mitts on. would the rear axle assy and the front suspension components be compatible with a book chassis ?

Hi Jon
Would 'gret feck off snorters' translate to rather large twin carburettors. I don't know, I allways seem to have trouble deciphering you common
folk!

Dear, dear me. The riff raff have definately taken over, and it used to be so genteel in here!
BTW Jon
Been speaking to someone tonight who used to race against you. Mr JBM, jesus, I could'nt get away quick enough when he started telling me about his
wife running off with a 20 yr old! I think he needs a shoulder to cry on!

looking at a shortlist of local donor cars its between a mk 1 1.6 sierra, opel manta GTE or a w reg escort (old type) or so the adverts say. i've yet
to look at any. Whats the recomendations. Ive been looking at the Mcsorley chassis plans and was wondering wether to use the wider or taller dimension
chassis. I'm going to get some 1" box tomorrow and make a start.

I wouldnt go for any of those.
if the mantas not rear drive, forget it - you will also be stuck for help cos few people use those. The FWD escort has absolutely loads of stuff on it
you cant use - like the whole car. (assuming you mean a mk3 escort hatchback.
if you use a 1.6 sierra, as soon as you ahve the car on the road you are probably gonna long for more power. the 1.6 has 75hp. the 2.0 has 105. SO,
choose the right car at the start and get 40% or so more power for absolutely nowt at all!
take your time over a donor - its likely to be a long project - dont rush the important bit of getting the right donor!
Using anything other than a xflow or bike seems to like a bit more height in the bonnet area.....and you might like a bit more width than the books 42
ins.

Steve,
Wasn't the Manta RWD? and weren't 'W' reg Escorts Mk2s? I know V's were (page 32 the "book")
I say this for three reasons:
1 - They both may well be suitable
2 - Just to argue with you
3 - To increase my number of postings

Oh yeah, I agree with the 1.6 Sierra though.
