The Vauxhall 8v 2 litre is as powerful as a Sprint, cheap as chips and indestructible (even by me!) Although belt driven, it's a NO-contact engine. It's an easy conversion and the injection wiring is only 5 wires to running! The Omega box that matches it has hydraulic clutch and the box is short and light with a readily shorten-able shift extension.

If you want to spend money later, a guy I know of in Stafford can get 240+ bhp from one of these, but I find circa 140 is "sufficent" for a road car.

Why wouldn't you?

The advantage of using an engine that was originally fitted to the Dolomite range, is you reduce your chances of officialdom sniffing around. Personally I think the rules are stupid. I can understand them wanting to stop people rebuilding a whole car from just a vin plate but I see no problem with putting different engines in.

Also I like the idea of using a retro engine and coming from a generation bought up with computers, I am fascinated by the way old tech like the a Dolly actually manages to work. The SU carb, for example, is ingenious.

As for the piles of scrap listed on ebay, my advice is stay clear. At the very least check it turns over by hand before even considering it.

The engine in mine was such a cheap purchase and it turned out to be not so cheap. OK I got it going in the end but I had to throw a ton of parts and time at it to make it work.

In hindsight I would have been better off spending more and getting a good one in the first place.
Should have said, no danger from the 8 point rule with the Vaux 8v 2.0, it goes in the stock unaltered shell fine. As for retro, it was introduced in 1600 form in 1981, just months after Sprint production ended and had grown to it's full 2.0 fuel injected glory by 1988. I'd say that's pretty retro, but the tech is a whole generation better. Yet it's such a reliable and versatile design that versions of it are still in production now. And the block formed the basis for the legendary "Redtop" and C20LET turbo engines.

The SU carb is very clever, but it's not as reliable or fuel efficient as a Bosch Motronic!

As Alun has said, buying ANY used Sprint engine is a gamble, even a cheap one can be a waste of money with NO re-usable parts to salvage. And the cost of rebuilding one is soaring, then there are the difficulties in getting quality bearings, chain tensioners, pistons, oil pumps and so on. Even decent gaskets can be a hunt and if you intend to use it in anger, this will be an ongoing problem that will only get worse.

I can understand going to the time, trouble and expense of doing this for a tidy, solid, genuine Sprint in its original shell. Not so much on a mongrel Toledo (like mine, no offence intended Clive!)

When I take on an engine rebuild I strip it, measure it and report my findings to the client at no charge. The client can then decide if they want to proceed or not based on my assessment. The engine will need to be shipped to me ie. not in the car.

I have built several engines over the years, so that doesn't scare me in the slightest, and all have been "refresh" rather than needing any real machining. Just a hone, new rings and bearings etc. In fact one of the best I did was in a 1300 herald, built from 2 engines (crank and head provided by one, block the other, pistons and rods from both to get a matched set within 1g.)

Anyway, expecting around 1K for a sound engine ready to be used, plus ancillaries. So Mr Weevil, ballpark about right.

Meanwhile, life is overtaking me. Organising the funeral of one parent, the other just taken into hospital after a fall. So nothing will happen fast.

An update.
Today I went and collected a sprint engine and gearbox. The engine is free, and full of oil. But has been standing for many years I reckon. As usual, it was good when removed from a car (aren't they all!) so the head and sump will be coming off as a minimum.

It came with a dizzy but no cap/leads. And a pair of carbs off a 2000, but I do have some short dashpot carb parts, so a bit of mix and matching is required.

(I also dropped in to see the facebook blue dolly with the Saab engine, but it isn't for me)

I've been looking at that in equal parts fascination and horror, love the engine, like most of the work done, but why on earth chop that huge lump of bulkhead out? Doesn't look necessary and puts it straight into BIVA territory, unless only used for track work, which from the spec might be a possibility, but limits it's appeal.

What's it like in the tin?

Metalwork is very good. Well, I couldn't get under it,but the shell is completely stropped with only few odds and ends attached. The owner works at a bodyshop who seem to have some VERY tasty cars in. And yes, happy to accept it was blasted, he explained the company have a company they use for their work. I couldn't find any evidence of "extensive" filler, but expect there to be a little for where repairs will have been carried out an probably some distortion/rippling fixed (totally acceptable) But it was the cut arches and the fact it was totally disassembled that did it for me. Plus the engine had the head off. Too many things to go wrong, and too much money spent on stuff that does't appeal to me (perspex "glass", ford PCD hubs /banded wheels and of course the arches etc, not to mention lack of garage space). But if put together it could be a very nice motor. If that is your sort of thing.
