saying that theres a few merc/bmw/Triumph V8/S6/V6 plants down at "buckies" from cars as recently as 8 years ago....although to be fair they're like bloody houses compared to the essex...and possibly just as heavy if not heavier...and most of them are going under 100 quid complete with some only making it to 40 odd K before they met their dismantler...

The BMW V8 looks like a pretty sweet engine, it's all aluminium and apparently is very light, but it can suffer from the nikasil problem, which requires a new engine block to fix (think I got that one right). A quad cam V8 sounds like a great idea, but from seeing the pics of this project it would be a very wide engine, and a lot of work to get it to fit. Great job in getting the lexus engine to fit in the car, looks like a fun project.

Yes, I think the thrashability of the BMW V8s is in doubt. 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.

We all seem to have gone off track here, but as were on the what V8 will fit,,,, well there are some nice engines now out there that will soon be in the realms of transplant money. One to really watch is the less well known Volvo B8444S, its a 4.4L 32V quad cam V8, the reason I say this is that it's a 60deg V8 so as narrow as that Omega V6 I fitted. Another bonus is that it's fitted to the XC90 thats bound to depreciate faster than a second hand newspaper.

This same Volvo engine is used in the Nobel M600 and produces 650bhp in that application. :shock: 8) :lol:

In standard form it produces 311bhp and 325lb.ft thats very respectable figures, and to top it off it's all aluminium head and block so even lighter than my Omega V6.

Now I'm just waiting for the prices to drop of that big old Volvo. :P Extra light 650bhp SE6a anyone?

Cheers
Nath

All BMW gearboxes have intregal bellhousings - so bit of a non starter

If I was going to swap in a v8 it would wither be a 2.6L from a montreal which would probably fit quite nicely :D but are hen's teeth :( or the daimler 4.5 hemi just because I like the sound of scimitar and hemi in the same name. 8)

YES!! for the Daimler 4,5 litre V8, a magnificent engine.
They can be fitted in SP250s so presumably in Scimitars too.
But don't forget they never existed in manual gearbox form.

sounds like your challenging someone to do it :D, I think that they are about 50 kgs heavier than the essex and there could be bonet clearence issues with those SU's but a powerbulge doesn't look bad...is it a 60 or 90 degree engine?

Think it's 90 degrees from memory,
but not too wide 'cos it's only got one cam in the middle.
The polished alloy rocker covers (with spark plug entries!) look magnificent.

Go for it!

I was bidding on one not too long ago, it was on ebay and hadn't run for 30+ years it went up to 600 and something but the reserve was at 800. Would have loved to get it but lack of funds etc... There so hard to find though and there are little to no spares, it would be very cool but touch and go if it needed a go over, mega money :shock:

The Daimler 4.5 is almost impossible to get spares for, not even headgaskets available, so avoid that engine.
It could produce over 1000hp when they used it for drag racing. It was covered in Practical Performance car some months back.

The 4.5 is very hard to get bits for even the 2.5 is not that well catered for.

Russ Carpenter used a 2.5 in his dragster - Best of 7.2 et - 179.9 mph - 1500 bhp, 0-100 in 1.2 seconds running Nitro and Methanol mix at 10 gallons per mile.
Not exactly a standard 2.5 Daimler.

Dad's next project is my brothers Coupe with a Daimler 2.5 - this will probably be Fuel Injected and managed by a Motec ecu.
The only reason for the engine choice is James has all the bits - the engine, the motec gubbings and his Coupe has been sitting in the workshop body off the chassis for years - he's not going to get time to work on it - and seeing Dad's on a roll...

Headgaskets won't be the end of the world as you can get copper ones made up for very sensible money these days (Ferriday) - which then makes them reusable as well :wink:

Or Wills' rings.

When Steve was selling the Sabre from Atlantis, there was a 2.5 Daimler engine on Ebay. Fair gave me sleepless nights.

Thank god for poverty.
