I'm interested now about this Daimler V8, from what I've read so far it's old, rare, impossible to get bits for, and possible to tall for a scimitar. So why the interest? From all that I'd give it a very wide birth, there must be some redeeming feature about it that makes people want them?

Well, it's old rare, impossible to get bits for...

It was a very highly advanced hemi V8 designed for Daimler by the BSA side of the empire. The 2.5 put out 145bhp (compare to Rover 3.5) and reved like a sewing machine, it was fairly light, and, importantly, bloody gorgeous to look at.

When Jag took on Daimler they realised the small V8 was more than a match for their 2.4, and so the 250V8 was born.

On top of that it was an "iconic"* British engine, with a very important place in British Drag racing and customising in the 60s and 70s. You either get all that... or not, ces't la vie.

Just to clarify, it looks like this:

WOOF

I can't think of much reason to put on in a Scimitar to be honest, although the original Ogles had them, but I thought it was a good match for a Sabre with an empty space at the front.

It really is a lovely looking engine. I'm just back from Defford ( near Malvern ) " Wheels and Wings " day. Among all the other nice things to look at was an SP250 with every bit of the engine polished and shiny, the rocker covers........ pure car porn.

Three Scimitars there, had a nice chat to the owners, plus a bloke I talked to who has four Scims at home but had flown in to the show.

A good aftrernoon.

The Daimler V8 is magic, mine would rev to 7000 no problem.
I sold my SP250 a couple of years ago (to someone in York, where it came from! It now lives in Spain).
I still miss that engine.
Here it is in 1974 ...

Actually I think the photo was was more recent.
Here's another of the car itself, at home in France.

:mrgreen: Dont you have to have 'struts' before you can brace them? AFAIK strut bars are usually only required on cars with monocoque bodies such as modern unitary construction cars rather than on cars with separate chassis's i.e. Scimitars which don't have struts and have wishbones instead :D

On modern cars, the "strut" in "strut brace" refers to the damper or McPherson strut top mount.

The Scimitar has suspension towers that also incorporate the damper top mount - and has a removable "strut brace" from new (slightly below the top mounting point).

Some early V8 conversions (and a couple of more recent diesels) left the brace bar out because the engine was further forward but it's generally accepted that there's too much flex without it (you have to jack the car up in the centre just to fit it as it flexes so much) - most V8 conversions now will have a modified strut brace fitted.

Isn't that it in the last pic on the left hand side - couple of white tywraps on it?
Isn't that just the standard support tower to body reinforcement bar that stops the frt flexing? Scimitars don't have strut towers therefore no need of a brace :mrgreen:

Yes the suspension has towers as part of the chassis design to locate the top suspension and shocker mounts but strut bars are for body flex with high powered cars with no separate chassis (which the scimitar has)to sharpen the steering - which is also debatable due to added vibrations, so the tower support bar which is not a strut brace per-say and is there for the GRP body flex so was there before any engine swap. May have to be modified for different engine applications sure but not a strut brace as the other posters were inferring.Tee

The bar running in front of the engine holds the tops of the chassis apart !

Try removing the bar - then jack the car up on either the NSF or OSF and see if you can refit it - - -ERGO - its a brace/support - and indeed it would change the handling of the car if missing

My son and I considered one for his 5a, but it is looking more and more like another Rover engine will have to go in, I have a 3.9L from a SD1 rally car lined up if it isn't too expensive. The gearbox is more problematic, The existing box is I think a 4 speed from the P6 range and they have a very notchy shift. I was thinking of going for a BM 5 speed box from something like a 530D and making up an adaptor to suit a Rover Bellhousing. Any thoughts or ideas? I should maybe start a thread on this work 'cos it would be a lot simpler to look back over any previous communications.
Why not stick with the LT77 or R380 boxes that are found in SD1s, Sherpas and Range Rovers and MG RV8's = no need for an adapter and probably cheaper than a BM box and easier to find too :mrgreen:

not great boxes although used behind many rover powered TVRs, Ford T5 is nicer and beefier, but more expensive of course

it doesn't matter if it's a seperate chassis or a "monocoque" - a strut brace is fitted to prevent the suspension angles changing due to movement at the top mount. In a modern "monocoque" that's body flex, in a Scimitar, it's chassis flex.
