OMG I never thought this could happen to me as I seem to be the biggest fan of the S6 in the Cerbera... But after being taken for a spin by Paul Black in his monstrous LS9 Sag i seem to have been bitten by the American bug!

Thinking of going down this road... Anyone else??

Feel free to share thoughts and experiences. My biggest concern at the moment is aesthetics as the LS3 Cerb (converted 4.2AJP) did not look very nice under the bonnet frown

Hi Alistair
Have you changed your mind as I never thought you would join me in possibly being in the Ls club.

Bit of a difference between an LS3 and the LS9 in Paul Blacks car?!?.....its not just any old LS9 !....I have been around Bruntingthorpe in Paul`s Sag a couple of times with him and it is awesome, the torque is amazing. I think if your looking at going the LS route then the cost of it needs investigating very carefully.

See.. LS in a Chimp I agree with.. It's just a better version of the RV8!

I'm sure Paul will be along shortly to tell you how its done!

His beast is an inspiration to anyone wanting to go LS and correct me if I'm wrong, but I do believe that his has achieved a genuine 200mph verified by GPS at Bruntingthorpe.

Come on Brummie, spill the beans...

Here's my take on it...

I've now been fortunate enough to experience the following big power TVR's:

1. a1rak's supercharged AJP8 Cerbera

2. Macdeb's 450hp turbocharged Rover V8 Chimaera

3. Sonnylad's 6.3 litre LS engined Cerbera

All amazing cars, all mind bendingly fast, all a credit to their owner's, but without any shadow of a doubt the LS engined car was the one for me.

While the LS Cerbera matched the power of the turbo Rover V8 car and was probably a bit down on the supercharged AJP8 one, the truth is on the road there would be nothing to separate them. But the LS engined car was definitely the one you'd want to keep and use on a regular basis.

No TVR could ever be described as sensible, so a modified TVR like the above three examples is really taking things to the extreme. But it was the LS engined car that felt the most refined and OEM while still being stupidly powerful at the same time.

From my experience it's very very hard to beat the combination of a modern 6.3 litre normally aspirated V8 engine in a TVR yes

All the above is just my personal opinion you understand, but after experiencing three different ways to create a big horsepower TVR I wouldn't think twice about selecting the LS option wink

Being refined and sensible ISN'T what a Cerb is about though.. The AJPV8 is brash, loud, brutal and a little uncouth. Exactly how it should be! If I wanted fast and refined I'd drop an LS in a BMW.

Wrong!

I think you've misunderstood "refined and sensible" here.

Putting an LS in a TVR doesn't remove the unique character of a TVR, it enhances it yes

The LS is exactly the engine to put in a TVR, trust me I've tried a few different ways of doing things.

The AJP8 is an iconic engine for sure and I totally agree there is a very strong argument to keep it on the grounds of originality and charterer.

But nobody can deny it also comes with some less than desirable traits, traits that don't always sit well with the guy who actually wants to use his TVR.

For sure there's a place for both, but for me the LS wins hands down on so many levels it becomes the no-brainer choice.

I can highly recommend going LS powered. I chose the supercharged route and achieved a modest 625bhp on a standard crate engine. The installation by Sportmotive is very tidy.

Hope you don't mind me asking but what was the cost of your conversion.
Pm me if you would rather not disclose it.

Less desirable traits? Such as? I can think of short service intervals..

An LS removes the unique character of an AJP engine'd Cerb.. I'm not saying the end result is a bad car. The LS is significantly heavier than the AJP I believe.

For a Chimp/Wedge etc, I think an LS is perfect, it keeps the RV8 character with much more power.

You're probably right, I can only speak from experience and the LS Cerbera was immense.

The AJP8 is certainly an iconic engine for many reasons, I remember seeing it in a perspex case at the UK Motor show in 1996 and just staring at its compact symetrical beuty for a good 10 minutes (sad I know).

And you could easily argue replacing the AJP8 with an LS is a but like dropping a big ol yanky V8 in a Ferrari.

In years to come we may well find people return the LS cars to AJP8 as these cars become more valuable, buying a classic car is often about experiencing exactly what the car was from new in its purest unadulterated form.

I totally get that, but I also get the whole LS thing too (in a big way), I guess it's all down to what you want which is why the debate will never find a consensus.

Horses for courses and all that but for me I sit on the side of the LS simply because it adds performance in a totally reliable and easy to maintain package, and I'm definitely someone who likes to use their TVR as much as possible.

Perhaps the answer is to have a Cerbera 4.5 AJP8 in the garage, and stick an LS3 in my Chimaera, best of both worlds as they say wink

Some fantastic posts. Thanks so much guys but I think I lit a match and am now thinking hmmmm but I know the Power 4.7SS will be pure, true and mental. So again I'm in no mans land!
