best OEM recipe for my build?
howdo folks,
I'm currently looking at my last 8 weeks in my massive rented workshop before I'm relegated to a single garage.
While I won't be starting my locost build till next year, I'd like to gather the donor bits now (and break a donor if needs be) before
putting them in storage till I need them.
As such, I've got to stop changing my mind every 2-seconds and finally decide on a running-gear package.
As a guide I'm looking at a locost with a vintage feel and more than a few S1 lotus 7 styling cues. It'll be de-dion but I'm still
undecided on the chassis - it will likely be a variation upon a Haynes Roadster.
What I'm looking for is solid, reliable performance using very common, metric parts (after completing two non-locost restorations lately,
I've got to the end of my tether with obsolete parts and hard-to-find BSW and UNF fittings). I'd like, wherever possible to use common
drivetrain units where the parts are likely to be available for years and years to come.
I'd also like an age-related number plate (so 2+ major components from a single donor)
Without delving into aftermarket/more exotic limited edition parts (Cosworth, Lotus etc), is the following considered to be the best possible off-the
shelf setup?
Engine: 2l blacktop Zetec, probably from a Mondeo (seen a couple locally) plus carbs or TBs for a classic sound
Transmission: type 9 from a sierra plus alloy bellhousing.
rear diff/driveshafts/hubs and front uprights from the same sierra
steering: mk2 escort rack plus modded sierra column - I'll be buying the rack new, is it worth getting a different/quick ratio?
Before I run out and track down my donor, could I check a couple of things?
1) are all Sierra diffs created equally? is a 7.5" preferable over a 7"? Which ratios are the most suitable?Discs/Drums?
2) are all Sierra type-9 boxes the same - is one preferable to another.
3) as I'll be buying the Sierra online and having it delivered, I can hold-out for a particular model if there is an ideal - eg should I get a
MT75 sierra over a Type 9 model or is it worth finding a diesel or a sporty one like an XR4 or even dare I say it... a cosworth?
Appreciate the responses. I've looked around and the price difference isn't that great between base models and sportier ones much of this
gap could be closed by reselling unwanted parts.

7" diffs are smaller and lighter - no need for a 7.5" at all best ratio for a CEC is 3.92 IMHO and most people seem to like discs at the
rear although it isn't really neccessary.
the best type 9 comes from a XR4 (RWD not 4WD) it has a higher first gear ratio but you will need an adapter for the longer input shaft - not a big
problem
Use a modified (shortened) Sierra rack with a sierra column
Engine is up to you - everyone has an opinion on that one!
just my 2p worth

what size wheels do you want? you struggle to get standard wheels at 13" with rear disks.

I'm looking at 15" steels with hub caps at the mo.

2lt blacktop on carbs will be quite tricky to get through IVA. just a thought.

All receipts must have your name and address on ..
Check donor is registerd & sorned to you..
(go buy a log book stamp numbers to suit on engine)
[ebay] BREAKING MK2 ESCORT 2.0LTR( 1300 + 1600), WITH V5''S ( MK1 ESCORT ALSO)  [/ebay]
Build type 9 g/box & 1300 crossflow..
After IVA - age related plate.. Visual emissions .. 1300 - low tax bracket..
Next day - put in Duratec - no change in class etc..
Own chassis & Build - First time pass!!
"7's" aren't really "cars", they are 'experiences"

Have you considered the tiger hs6 ?
This may force some of the options.

Fair fewer combinations of gearbox, diff, engine etc as well, which is good in my book! Pre 95 will be easiest if you want to stick with carbs.
