I'm sure it's been discussed before so if anyone could point / link me in the right direction,
I'm a ex speed six cerb owner looking to purchase again, I'm moderately aware of what to look for on a sp6 cerb , rebuild etc but I know nothing really of ajp engines and what to look for when buying, especially on higher mileage cars ie a 4.2 with 65000 .
Any v8 advice please
Thanks

V8 AJP the only way. I own a 4.5 Cerb, and used to own a 4.2 Cerb. Both with no trouble engine wise. Owned a SP 6 350t.

Nightmare!

However if you get a sorted SP6 then I am sure all would be well. I prefer the torque of V8,s.

The AJP police will be along shortly to ruin this thread so I'll get in quick.
V8 has more torque and is delivered lower down the rev range. Seen as more reliable but plenty have required rebuilds also. Not so smooth as the six in traffic.More difficult to work on than the six as things like the starter motor are hidden at the back of the engine. The 4.2 is on par with the speed six speed wise and the 4.5 is faster than the six and the 4.2.
The six was flawed from the factory with most having sub standard parts installed which led to premature failure. If you get one with a full rebuild by TVR Power for example it should be bullet proof and one or two have now achieved over 200,000 miles with no engine issues .less torque than the V8 and the power arrives higher up the rev range. Generally smoother in traffic than the V8 and there are far more speed sixes out there than V8ajps.
The Ajp police will tell you the cerb should have a V8 but that is nonsense both enjines are well suited to it. The six is generally cheaper to buy than the v8 which means you can get a newer example for your money.

Thanks for the input, I will be continuing the search in the new year, I keep missing ones I like, I'm very fusy about the interior which doesn't help, but due to weekend work and some for distance you have to be quick, loved the blue one at agger, just missed a viewing with the private seller before he sold it to them and now they've sold it !
I see phil phodonous is now doing inspections, maybe I could use him if I'm busy. Lamborghini orange from up north? Great price , but no.
Thanks

I have a 4.5 AJP Cerb, love it brutishness, a mate had a 3.6 Tuscan, really didn't like the engine.

Mate's engine blew up so it became a 4.3 built by STR8SIX, and not it has the feeling of immediate power of the AJP but my word is it smooth.

It would be a close run thing now which engine is the more brutal, so much so that mine is now in bits being upgraded to a 4.7, this will keep me well ahead on the power willy waving stakes but the SP6 will have the smoothness.

So if you want a car that feels like it is about to rip your head off go for an AJP, if you want something to whisper in your ear gently while it removes your head with the precision of a surgeon then get an updated SP6 it is a brilliant piece of kit.

Any Cerb has more than enough power for the road. Unless your going to track it or wave your willy about don't get hung up on the engine, buy the best car you can find regardless of the powerplant.

PS: Your previous Cerb looks a peach wink

V8s are good but the sound of the S6 is hard to beat. And that's coming from a V8 owner.

Just factor in a reputable rebuild cost into your purchase price and you're away. Do it once and do it properly and you woes are gone. smile

If you get and AJP8 then I definitely recommend a Joolz remap, especially if it's a 4.5. I have no idea why the factory 4.5 map was so poor but it was, and if you fit the Whirlwind induction as well (before the remap) then your car will be transformed.

I agree, and at present I'm not really fused as long as its a cerb,
Thanks regarding my peach! It was indeed, and only had to lose it due to parking problems, then got shafted by dream machines going bust so still chasing the money on that one !

That'll keep you busy 'til the New Year. byebye

.... and on a more helpful note....

Only owned an AJP8 (4.5) have taken her from 32K to 92K.
Don't understand what people mean by "town manners" - She's a pussycat.
The only thing that annoys me is the ridiculously enormous turning circle.

Try then buy.

{Happy reading)

I think the turn circle issue is over come very easily, little lock applied, good dash of rpm, dump clutch and see where you just came from hehe

Try them all if you don't know what type of engine you want. I wanted a 4.2, I love the clatter idle, raw power and that it's a V8.
I understand the appeal of a SP6, it just isn't for me at this time wink, and I couldn't afford a 4.5 RR!

Some great comments , thanks, have my eye on a 4.2 in grigo titanium being sold by tvr mads, currently undergoing a chassis refurb and ready for viewing mid January, looks nice but just need to confirm what level of refurb is being done, the work is being done at central tvr , just not sure at present if the cars staying there or going back to mads. Wasn't the car previously advertised at central ?
