Nope. AM heads are completely different! Different port sizes, different port centres, different port lengths, different cam retention / covers etc. Nothing is inter-changeable (even the bearing sizes in the block are different)
If you want to fit a JLR s/c motor, you'll have to put the whole thing in, and then you'll find the engine mounts have moved, the bellhousing doesn't match, and the starter motor goes straight through the steering column.
Interesting thanks. If you want to fit a JLR s/c motor, you'll have to put the whole thing in, and then you'll find the engine mounts have moved, the bellhousing doesn't match, and the starter motor goes straight through the steering column.
So are the heads completely non compatible, as you couldn't swap the entire head? Are the bolt patterns different too.
And just curious are these changes unique to the 4.3 or does it have any similarity to the 3.9 variant?
18K...I suspect Aston tax is being added here.
By the time you have done the recommended changes to suspension and brakes this is sounding more like 25k.
I am a big aftermarket tuning fan, but this conversion would seem a little expensive at 8k, bearing in mind it's bolt ons to standard engine.

Well a V12 S will cost over 100K
An original V12 Vantage is about 90K.
An original and larger V12 DB9 from 2003-4 is 35K but you can pick up a V8 Vantage for the same price or one a few years old for 60K. Add all the goodies and it is still much cheaper than all the other options.
You also get Supercharger whine, better handling and lower weight than the V12.
Given that an Audi RS4 B7 Supercharger kit is 22K then this seems reasonable.
Good idea to extend the interest in older Aston's as the new ones come on stream.
No it's not 22k it's 12k all in with the water injection.An original V12 Vantage is about 90K.

You know what? It does, more modern car, more powerful, better autobox than the crappy Aston flappy paddle one. looks great, plentiful supply of those lovely blue ones.
I pick up my v8 vantage on Friday.
Ones an Aston, one isn't... and having the XF as a daily sealed it really, almost the same to be inside the two things.
If I decides it's a keeper this modification does seem pretty good on the face of it, assuming it comes with lots of warranty for your £18k ?
you'd take a kick in the nuts come resale time, so needs to be something you really want to keep.
Also, a £30k aston will be a bit of a dog in my humble opinion, £35k for good / reasonable ones (some nails in there a that price too), £40 for something very clean with some warranty.
If you were going to do the suspension upgrades as well wouldn't you grab a slightly tired one? I would as the tired parts are going to come off anyway.I pick up my v8 vantage on Friday.

I'd spend 27k & grab something like this:

FFS does it really matter? Would you be driving this daily? There's more to life than fuel consumption and that would be a drop in the ocean on the depreciation on the mods.
There is nought wrong with the standard 380hp if you drive it like the revvy NA it is, plenty quick - let alone with another 200hp.

That would seem an unjustifiably high price.
Re: the Aston, as it's an AJV8, then I'm guessing supercharging one should be fairly easy using bits than Jaguar/Land Rover use. Even if you went the whole hog and used a 5.0 litre block.
I admit, I don't know if this kit is just the blower, or if it includes new pistons and other internal engine items. If the latter, then maybe the price can be justified.
If it's just the blower, then it does seem a lot, considering you can buy entire blower kits for other vehicles from $5000-7000

Entirely different engine, nothing is interchangeable except the fuel injectors rocker covers and the water pump.Re: the Aston, as it's an AJV8, then I'm guessing supercharging one should be fairly easy using bits than Jaguar/Land Rover use.

I get that that is a load of power but 18k is just silly money.......You add that to a 30/35k Vantage and you would never get your money back when you come to sell......Try selling a 2006 Vantage for nearly 50k.....
You might be surprised you wouldn't get all of it back but people will pay for performance as long as it's been done properly.For example my mate had a supercharged B7 RS4 with R8 brakes uprated clutch coilovers etc he had the car just over 2.5 years & then sold it for a 5k loss we worked out 2k of that was normal depreciation now to lose 3k for all the extra performance & smiles (nigh on 600bhp) it was worth the loss.
Plus look at it another way let's say all in with the suspension refresh/upgrades uprated clutch uprated front brakes etc your fully sorted Vantage comes in at 52k which would land you a 2008 4.7 with 20-30k on the clock or you buy a 2006 with 58k on the clock for around 29k & spend the extra on upgrades, you can't put a price on smiles for miles they're a lot harder to come by these days.
Even on the bike.How much is the cheapest V12 Vantage 80-90k?
For nigh on half the price you'll have a well sorted Aston with 600bhp there will be a buyer for it after you've finished with it as long as you price it sensibly.
The real point is that you get the power and the performance of the V12 for an all-in £50k, assuming you buy well. £50k's a lot, obviously, but look at the depreciation on the V12 - a new one's what, £150k, and will (conservatively) lose £30-40k pretty much the moment you road-register it. The older V8 simply wouldn't drop as fast, and at £30k has probably reached a base, so long as it's kept in tip-top condition. So financially (accepting that both the V8 and V12 are fantastically expensive cars that make no sense whatsoever), the V8 isn't a stupid decision, even with the heart-stoppingly dear 'charger added.
If I were looking for the perfect Aston for me, the supercharged V8 would be the way I'd go. But then, I love superchargers.

Probably not, as (if Wikipedia is to believed) pretty much no short engine component of the AJV8 is actually shared between the Aston and Jaguar engines:The cylinder block, cylinder heads, crankshaft, connecting rods, pistons, camshafts, inlet and exhaust manifolds, lubrication system and engine management are all unique to the Aston Martin version
-EDIT
Oops, looks like Max Torque's beaten me to it!
Interesting concept and one that has clearly been well-researched and tested.
I am a 370Z owner and Stillen provide a popular supercharger kit for the Z which all in with ancilliaries could probably be done for £10k to £12k. Result is a very driveable car with around an additional 120 - 150 bhp, that still retains the power-delivery characteristics of the standard car, just with more grunt across the range.
On the face of it I think £18k does sound like rather a lot for a similar kit. However, you are looking at a very impressive 200bhp gain. That is huge - around a 50% hike in power with reliability by the looks of it.
What most PHers think about the price is largely irrelevant as most commenting aren't Vantage owners so not in the market.
Just because £30k is now the entry level price for a Vantage, it doesn't mean that is what current owners have paid for their cars or what they are worth. Most owners are going to be well-heeled and if they fancy a power hike for their Vantage rather than upgrading to a newer Aston, this would likely be an attractive alternative. I suspect the average AM driver is not likely to be bothered about doing the conversion as cheaply as possible and would prefer a tried and tested route.

Its not really though is it, this is a bespoke, high performance, hand installed kit, lets say parts cost circa £10k which is easily believable considering these things don't come off a production line in china!Leaving £8k in labour which works out at 160hours @ £50/hr.
Small volume engineering works is expensive, but you can save yourself that money by not buying one.....
