4.5-litre TVR Speed Six Conversion

New upgrade package promises 455bhp and a five year warranty



Owners of TVR Speed Six powered machines will have a new option in the quest for engine longevity at the end of this year - a 4.5-litre, 455bhp(est) conversion from TVR Power.

The new Supersports 4.5-litre package will not be cheap at £8,500 plus VAT, but TVR Power say they have a roster of happy customers with their 4.3-litre, 430bhp conversion. That version is still available at £6,500 plus VAT, if you want to join the ranks of the 57 cars they've converted in the last eight months. The extra cost of the 4.5 conversion covers the need for cylinder liners and a lot of additional machining that's required, all of which is carried out in house.

The package includes:

Steel billet knife-edge crank shaft assembly
H section billet connecting rods
Interlock steel top hat liners
Bored and honed (original) aluminium cylinder block
Bespoke pistons
Lightened flywheel
Ported cylinder head
CC Combustion chambers
Performance camshafts
High flow injectors
Bespoke map (on all applications) MBE only

"After the success of our 4.3-litre engine we have taken the power, torque and reliability to the next level. We have the confidence in this engine to extend the 5 year unlimited mileage warranty to our customers who choose to upgrade.

"This package will be available from December 2010 after it has been through vigorous road and track tests including the Nurburgring and all over Europe in TVR Power's own Sagaris," the company says.

Plenty of time to start saving then...

Looks good to me, thought Melling offered something similar in the past.

It's almost as if Haymarket deleted a topic to create a news article.

Well done Dom.

I know very little about these 'kits' 'upgrades' whatever you want to call them and i know you have to cover development costs, AND that a lot of work is done on them by reading the published list, but they do seem a little expensive? especially the difference between the 4.3l and the 4.5l? Just a casual engine related comment.

And we hope to see Doms car on the rollers at Raceproved on the Chatsworth Saturday. So a great opportunity to see the awesome power on a good 'baseline' set of rollers (ie Joolz' set).

RIIIIIGHT.

5 year warranty! Now we are talking.

I love TVRs.

Not only the cars, also the people who service them make all the right noises to keep them running.
GREAT!

5 year warranty is pretty amazing.

Does that cover ancillaries failure (oil/water pump) and subsequent engine destruction?

Isn't that what the "news" button over there ))----->> is for?

ie - find a newsworthy thread, hit the news button (as opposed to the snooze button hehe ) and Bob's your Mother's Brother...

The amount of development work Dom puts in this ought to be an absolutely stonking engine. I wish i had the cash (and the justification after a rebuild last year!!)

Great that we are actually allowed to talk about it now too after big brother stopped the original thread rolleyes

This is great.

Now I would like to see some articles on other companies in the TVR business - either engine builders or aftermarket 'keeping cars on the road' providers (chassis, body parts, glass for rare cars?)
