I should add, acquiring an LS3/7 is cheaper from the states. I am there on business quite a bit so will be purchasing from there and bringing it back. Saving a few thou. Who quotes you that ridiculous price? There's so many pisstakers out there. Best of luck.

I was quoted £24k, and that was just for a bog-standard LS3, not LS7!

That was Topcats.

I ended up having Powers' 4.3 S6 upgrade, and am very happy with that - around 400bhp in a car so light is more than enough for me..

Pretty sure once you add taxes, shipping and duty to the cost the crate engine isn't massively different in costs.

Here's an all in crate engine (low price guarantee)
14k usd. No wiring loom etc

Are you doing this your self. I looked into doing it myself and you'd be hard pushed to do it for the figures your quoting. There's plenty of custom items that will need fabricating, on top of gearbox, prop, drive shafts, stand alone management (you could play with the GM management).

In the end I built a high end FFF speed six.

Compared to a standard Speed 6 rebuild from TVR Power at £5,400 (inc VAT and 3 year warranty), an LS conversion is always going to be more expensive. The question comes down to the value of any increased performance from the LS3 / LS7 against the 4.3 / 4.5 / 5.0 Speed 6 upgrades. That's when the real costs start to rocket.

as for the costs if you take e.g. the 4.3 or 4.5 upgrades youre very fast in the plus 10K region without any too special bits. take a look what can be done to a LS1 e.g. with some cams fast intake etc. and youre well above 450 horses on the safe side and the whole lump can be had for some
dollars in the states.

the question is more how long are you gonna keep it ? if there is the i am not sure factor put maybe a second hand engine in or do a small rebuilt and thats it. you wont see the spent funds for the LS conversion when you sell the car.

also 25K for a drive in drive out conversion is a nogo.

From memory (which may be wrong) I'm not sure the LS1 will drop straight in to the chassis. The ls7 will, but for example, quickly looking on eBay throws up just one second hand ls7 at 7.5k gbp.

It's always struck me as an odd thing to want to do; if you want an LS engined car there are plenty of others to choose from.

Why, the Smolenski era cars were much better than the Wheeler era cars!

LS engine conversions make much less sense now than they did before TVR Power and Str8six made the Speed 6 reliable, there is simply no need for an LS engine in a TVR as a response to unreliability. If you want more power or a V8 noise, then that's a different and more expensive agenda altogether.

It was a joke... I love his Vulcan conversion. I'm having the LS conversion too. It's just not popular thing to say. Speed 6 still going great guns though.

Why don't you just get an ultima gtr. Purposely designed for the LS, and far more capable than any TVR chassis. And with the real money you'd spend on an LS conversion you wouldn't be massively far off the price of one on the used market.

I disagree that the LS conversion is 'unpopular' within the TVR fraternity. Plenty of conversions being done and completed.

Maybe it's a Tuscan thing?

There is another option for a reliable, 450hp, V8 with abundant supplies of spares. Conversion for around the price of a standard Powers rebuild including engine. I know of a Tuscan being converted at the moment.

The one I'm thinking of is being turbocharged.

Supercharged Jag V8 sounds nice. Where's that at?

It was in here, on the continent I believe.

What v8 are they turbo charging exactly.

What exact information are you looking for? Engine number?

biggrin

Until it's done all I can say is that it is over 4lt and from a 4x4. After all, it may not work! It has been fitted to a mk1 VW Caddy previously though.

It's being done in London.

Make would have been fine biggrin Just curious. Having just completed my syvecs install the flexibility it offers would allow you to stick anything in the gap...

And please tell me the 4x4 doesn't have rover in the name.

Cheeky ask time. How easy is it to swap out the S6? Like for like not a conversion.

Not particularly difficult once you know the order of operations. I've got a ramp though, not sure I'd fancy doing it on stands. What are you thinking of doing.

now this is what i've been thinking, my previous rebuild was a 400se wedge and thought it would have been a great conversion.........it just so happens that my family run around is a 4.2 XJR (love it to bits, so smooth), its quite a small looking lump but don't think the missus would appreciate me ripping it out for project lol

has any one considered the merc lump? the 6.3 is still going to be an expensive option but an older s55 or E55 accident damaged could be a reasonable priced option.

only major problem i see is that they are both auto's
