I would add entire rear alxe as well - might as well try to use the front brakes and the electronics

Problem is, you won't want to use the Omega rear subframe and trailing arms, which must weigh a ton, so you're into designing a chassis around the diff and hub carriers. You may as well just use the Ford bits that someone else has already engineered a chassis around. Sierra diffs are bomb proof and plentiful, including LSDs, which is obviously a requirement. 8-)

The engine and box is a different matter. You just have 2 engine mounts and a gearbox crossmember to bolt on somewhere.

I've seen a Westfield running an X30XE before. Looked a nice fit.

I would also look carefully at the weights of all the available engines and boxes first. I suspect you could do better than the Omega bits and weight is all important when the engine and gearbox is going to be a third of the weight of the car or more.

I suspect the Omega V6 plus gearbox will be about the same as a Pinto plus box.

That's probably about right, and with the added advantage that you should be able to locate the weight further back with the V6, but the Pinto is a pretty hefty engine in the first place.

Do you know how much a bare V6 weighs, out of interest?

get it vigorously checked for safety when it's built too, a friend of mine paid £23,000 for his westfield, had it on the road just over 30 minutes and it slid off in the wet at under 25mph, and this is how it looked afterwards from making contact with a tree, and this HAD been inspected by vosa prior to having a registration issued

the story isnt completely accurate in relation to his injuries, and nor was the car just "broken in 2"

The car was broken in two by the impact
.. or cut in two by the fire brigade?

Oh, dear.  :( I do feel for your mate, and hope he has made a full recovery.  :'(

He isn't the first person to have come a cropper relatively early in his kit car driving career, unfortunately. TBH, though, and without having any knowledge of this particular case, I would say it's unlikely to have been a problem with the car.  

There is a world of difference between driving a car like that in the dry, where they are difficult to unstick without behaving like a hooligan, and in the wet, where the amount of power versus the weight and traction available can make them very easy to lose indeed.

We all learn that lesson pretty early on. I'd be lying if I said I hadn't done the same. I suspect the only difference relates to the position of the tree relative to the car. :(

So how easy is it to use an Engine and Box from an Omega, and the Diff + Rear setup etc from a Sierra?

Im guessing the prop will need modding?  :-?

Yes, essentially you need the front end of an Omega prop and the rear end of a jellymould prop and get a specialist to build a custom one out of the two and balance it. Not rocket science nor that expensive but obviously it's not something you want to fail. :o

Engine mounts and gearbox mounts will need fabricating. You might come across areas where chassis mods are required - bracing struts in the engine bay getting in the way can be a problem for chassis designed for 4 pots, and sometimes you might need to re-route the lower steering column to avoid the engine. You'll need to fabricate some exhausts, of course.

It's a lot more of a challenge than using a kit that's made for the engine. That's normally just a bolting together exercise, although it depends on the quality of the kit as to how much you have to do.

If a V6 Omega engine was used for a boat or kit car project then what electricery components would have to be taken over in order for the project to fire up and run correctly.  Also the same if the Auto box went to a project as well.

TIA. :y

You'd obviously need engine ECU, immobiliser and transponder. You could configure the engine ECU as a manual so it doesn't require communication with an autobox ECU. It will probably still whinge about not being able to talk to the ABS/TC ecu but not sure if that would affect the running. Autobox would obviously require the auto gearbox ECU and its' connection to the engine ECU and associated looms and switches.

TBH, I'd be tempted to replace it with a mappable ECU as I'd inevitably want to start tuning it. ::)

Kit car would have to go through an SVA test before being registered (currently £185 -- going up to £500+ in April).

Have you thought about a buggy ( at the budget end of the market) ? A couple of us are in the throes of building these:

At the end of April they are changing from SVA to BIVA --- very slightly chnaging the standards to pass but increasing the fees enormously. They have concluded (after 10 years) that their inspectors find the test too time consuming and wasn't covered by the original fee!

They haven't settled on the final fee -- but £500 was suggested in the draft paper

Best bet is get one off eBay that has been registered and allowed to fall apart --- strip it and rebuild it using the original identity.

the car broke into 3 on initial impact and finished in 5, he had a severely smashed leg with skin and muscle missing from a lot of his left foot, he had breaks all over his right foot and also bruising to his face and a fractured skull with nerve damage resulting in temporary loss of use of the left side of his face, he may be out of hospital this time next week if one leg is healthy enough to bear weight, he's recovering fantastically, probably thanks to the 4 point harness (some stories said he was hanging out of the car, but he wasnt)

the car had been through the full SVA inspections, which is what's worrying!
