Yep, read that article yesterday... Very impressed.
Can the poor reputation of the Speed 6 now be dismissed??
Seeing as 40 years on people still froth about Triumph Stag engines then no. Sadly it is a stigma that will forever be with this engine regardless of what evidence is there. Can the poor reputation of the Speed 6 now be dismissed??
In a world where many people are convinced of alien landings, CIA blowing up the World Trade Center and God knows what else, and for as long as TVR owners skimp on running costs, as happens every day then there is f
k all chance of the masses ever letting it go. Short of a million mile S6 winning X Factor and proving that Phil the Greek had Dianna assassinated all while re opening the coal mines and bringing milk back to schools then we will remain at the mercy of the great British pubic and their encyclopaedic knowledge and towering intellect.

Great job by Power too, just shows what can be done.
If my engine ever neads rebuilt and it certainley doesn't at the moment with only 32k miles on it ang pulling beter than ever ,it look increasingly likely that it will be TVR Power that it goes to, but, the original poster doesn't say if it is a standard rebuild,or a 4.3.
If it's a standard 4.0l rebuild and it has done over 100k miles then that looks like the road I will go down. I would like a 4.3 but at almost double the cost of a standard rebuild not convinced or afford that outlay.

That also is a very impressive (technically) photo!!
Thank you very much, thats one of my pics 
The rest from TAG II/Breakfast Club on the Sunday are here...

my favorite colour too!It's a shame they all are not that reliable as that one.
It's also the only engine on PH to gets it's own thread topic :

That’s because all the Porsche and BMW owners are still in denial.
They couldn’t possibly bring themselves to admit on a public forum there has been problems with their multi million pound budgeted engines.

It's worth doing a bit of searching on Porsche forums for 'RMS'. Seems like a load of problems particularly with the 996 model which clearly p*ssed off quite a few owners. However I guess they were better at keeping it out of the main stream press. Similar to BMW with failing turbos in their twin turbo engines, although this was highlighted on an EVO long term test car, and electronic gearbox problems in Mercs. All probably with PR departments larger than TVR R&D.
Guys - BMW did have small end bearing issues with their 6 cylinder 343 bhp 3.2 engine early on but resolved the issue and yes indeed Porsche also had issues with their flat 6 engine not really sure if they fixed it but I'm pretty sure they did.
There are hundreds of ex TVR owners around who really wished all the promises made by TVR for many years about the issues with the speed 6 having been fixed were true and it is a major reason why many die hard fans became disillusioned.
Such a shame as it was a nice little engine with a great power delivery and yes I owned a T350.
Hopefully Dom has finally fixed it but only time will tell.

What more proof do you need?
This is exactly the problem.....so called die hard fans who should know better still rubbishing the Speed 6 and not letting by gones be by gones.
I've sat by and watched this with bitten tongue as long as I can.This is exactly the problem.....so called die hard fans who should know better still rubbishing the Speed 6 and not letting by gones be by gones.
All hail a speed 6 that has been re-built and then got to a mileage that any one of a hundered other manufacturers engines can manage as a routine task!!!
Look. The speed 6 is a fundamentally flawed engine.
Can it be made to work...yes
This does not make it a good or reliable unit, It simply isn't and any amount of delusion will not change the fact that we have 1 or 2 re-built engines that have managed a half decent innings on a very low volume production engine which has a reputation for failing because it does actually fail, whether valve recession, half time bearings spinning, valve train failure etc etc etc... Its a poor design of an engine.
Is it a cheap engine for what it is when stacked against other super car engines, Yes. does it give good power when it is working...Yes. Does it sound nice...definitely..Did TVR not have an opportunity to develop out the issues...definitely.
Dom has obviously persevered and we now have engines which are doing what they should have done all along...
But please in the light of all the servicing workshops full of Knock Kneed T cars with engines being routinely crated up and down the motorways to TVR Power..Don't try to delude anyone.
The concept of a low volume manufacturer building his own engines is applauded. Will they eventually be revered as an all time classic definitely, But it aint a good engine.
It's very much a poor engine that generally over time has had a lot of its flaws ironed out through the dedication of a few that have stuck with it.
The speed 6 will always be a design classic, but their are 2 kinds of speed 6's those that haven't failed yet and the re-built ones!!
And Please to all the armchair mechanics who try to compare Porsches having similar engine issues please consider the numbers built!!

(No I wouldn't do that from my ARMCHAIR, and I prefer to be known as an engineer, but the Porsche engine is worse) ( Nikasil still haunts BMW, Soft heads on Porsche's, and Jag had its fair share of problems with the AJ6)
I have to disagree with you totally, the SP6 is a great engine, the power delivery is fantastic, it is a pussy cat in traffic, and an animal in the open.
Should TVR have sorted it earlier, then yes they should, was it a massive project for a small team, yes. Is it a great engine then yes. There are very few finger follower 4.0 flatplane, throttle bodies engines making up to 400hp with such a distinctive power delivery. Will it get better, I would say almost definately. fff, fff gen 2 , 4.3, 4.5, 5.0. A variety of tweaks to the engine could result in significant gains now the reliability is well known as shown by the Svecs ecu.
Here's to the next 10 years of SP6 development!
Not looking to fight about this, but it is night and day to how it was a few years ago.
