I've been drooling over TVRs for a couple of months (years) and am finally in a position to make the plunge.

What is the general concensus on the Speed 6 engine, I've heard of failures and expensive rebuilds and that the V8 is more reliable (although running costs are higher).

Are newer versions of the engine less likely to fail, have the problems been ironed out in later cerbs?

I've test driven several V8s including a Red Rose, but I'm wondering if I am doing myself a disservice by ruling out the speed 6, after all it's the same engine used in other TVRs.

Any opinions greatly received.

Without wanting to open a



it is probably still safer to stick with a V8.

I agree with you, TC, but it's worth mentioning that more and more of us AJP owners are starting to be concerned about parts. With the Speed Six, that is not an issue, it being the current engine of choice for TVR.

The only new part you'll struggle to get for a AJP8 is a block .. everything else is available in a variety of stages of tune so no worries there thumbup

The SP6 is a viable choice now there are good engine rebuilds out there, so no need to cross it off your list at all. In fact if you want one buy one now before residuals start levelling on the back of increased consumer confidence.

At the mo a SP6 cerbie is a bargain, and as long as someone hasn't ruined the handling with 18 inch wheels they're the best handling TVR ever made, a proper driftastic machine with instant throttle response and a comfortable everyday ride to boot!

My money wuld still buy an AJP8 just because of it's potential power output, but it's not for everyone .. crikey it's a bugger when TVR's greatest ever car gives you a headache over which variant to buy!

If I was looking now I'd consider a S6 as its still in production and there now seem to be ways of ironing out the bugs. As joo says, get one now while they're still a bit of a bargain and factor in some money for a rebuild/improvment if required. They sound great too!

Yes, the speed 6 is a good bargain at the mo. But then again I've seen some AJP8s going for stupid money on the classifieds too. So thats the money standpiont.

As for the car itself, go for a 4.5. If you get a speed 6, you'll hear a decatted 4.5 on a TVR hoon one day and kick youself in the nads very hard and ask yourself why you went for the 6.

What do you want, full cream or skimmed?

Any ideas on what the power output diiferences are between the SP6, 4.2 V8 and 4.5 V8 in the real world (i.e dyno results) and not TVR quoted figures ?.

All pretty close, and in the real world very fast. However, they're not alone now, there are a number of cars that are close or as quick now, even some uber-saloons.

4.5s seem to have the most tuning potential, so if you want to spend your time on a rolling road, they're the ones to go for (apparently) hehe

I've done track days where there were S6s, 4.2s ans 4.5s. All fast, but not as fast as Caterhams/GT3s etc.

You clearly haven't heard my de-catted S6 with a sports zorst then

Since the re-build by TVR Craft the engine has distinctly different note - just ask Boss Cerbera wavey

Unfortunately a new house purchase means that I'm also having to sell her after investing a small fortune over the past 18 months cry

Talking about exhaust 'sounds', I've just gone froma 4.2 with a sports exhaust, to a 4.5 with a standard exhaust, and I much prefer the sound of my current one.
A Sports exhaust is Noisy, the standard has a nice growl to it, without being overly noisy. I'm not really into the 'Its got to be really LOUD thing, but it's subjective, just like music.

Have you thought of decatting the Cerb, but keeping the standard back box. Its what I have, and you get the best of both worlds. Quiet enough not to upset anyone at low throttle, and just menatl when you give it the berries. All with plenty of pops.

JT - Sorry to hear you are having to get rid of. Not heard a decatted 6 yet.

This is what my 4.5 has too. Best I reckon - standard rear box better for power too. [Edited to add: for the time being]

In my opinion anyone buying a second hand S6 right now or in the future needs to understand the engine issues and ask the seller the right questions. Further in my opinion there seems to be an increasing number of owners of late seeking quick fix bodge jobs (on the cheap). I speculate they will then be punting their cars on months later. Just check out the S6 engine forum at the moment there is at least one bodge job thread on this very line of subject now. Not good for the mark.

Is there a quick way - other than history - to check out if an S6 is good?

I mean, listening to it, smoke, smoothness, tone . . . or will it just say 'bang' and go ad random . . .

The mill in the Sagaris has everything you need: torque at low revs, linear power delivery, classic Brit exhaust note, excellent mpg.

I understand folks who drool over the 8 . . . but for a few cents less you've a sportscar as fast as you'll ever need.

A sixpot Cerb is a fine car now, isn't it. If there wasn't the V8-version you wouldn't bother I'm sure. As for the recent Tams, T's, Tuscs 'n Sags they look like fine cars to me. For the money they offer Rari performance. Even including a possible rebuilt you'd have 3 TVR's for one same period Italian . . . or two Porkers . . .

A Boxter? Anyone mention that one get outta here . . . Just look at them hehe

Agreed, that's my preference yes
