Why change AJP to LS1
Discussion
I changed mine because:
1. As much as I like the AJP. I didn't like the costs of a brand new engine after mine went bang (albeit after it had done 100k miles).
2. It seemed a good idea at the time. It still does.
3. LS1 engines are a lot cheaper than a replacement AJP.
4. It was a great research project.
5. LS1 spares and maintenance is a lot easier than the AJP.
And yes the car is running and moves. As soon as the new cats arrive, its MOT and go play time.

I'm changing mine cus I'm bored 
Seriously, I love my Cerb, and I want to be able to keep it runnning myself, thats half the fun for me.
I looked into changing mine to a 4.5 ajp and after driving Craigs I wanted 4.7L but unavalibility of parts just rocketed the costs.
My criteria was More horsepower, More peace of mind, and if I do put a conrod through the block at the Nurbergring I can shrug my shoulders and get another one for less than a rebuild of an AJP.

A tuned (and relatively cheap) LS (post std LS1) will murder an AJPV8 unless one of the very few supertuned ones.
AJP's cost alot to rebuild and LS's don't break!!!!!!!!!!
44 cars went on a run to france 2 weeks ago and (no confirmation) but I am pretty sure mine would have been the fastest (though Fubars was Damn Quick - a Super tuned one - race cams and a good bit of other Austec work). One car broke and is all now stripped for a rebuild and fix of what ever broke. On gues which one?
Sorry Fubar (see ya next week at the Pub).

Can't seem to remember seeing your car at the last couple of meeting Jon.. engine problems wasn't it..AJP's cost alot to rebuild and LS's don't break!!!!!!!!!!

NO - like I said it was an RV8 pressure sensor - they go about once a bloody year!!!
It is a Tarmac munching BEAST!

Yes you're quite correct! We don't care about those things!

No not change your 512 engine. Not alot you can do with poor packaging on those (gearbox UNDER the engine). And a mildly tune Griff500 would likely see it off let alone a bonkers tuned TVR

Strange. Should i change the engines of my ferrari 512 boxer and alfa gulia GTA now too for a LS1?
Ls1 one is cheaper and faster then my ferrari 512 engine but i prefer not to change the engine.
But ok i think TVR drivers do not care about those things.
Ferrari have always been exotic, ie complicated and expensive. People leave this as it is. If you want better performance for the money, don't get a Ferrari in the first place.Ls1 one is cheaper and faster then my ferrari 512 engine but i prefer not to change the engine.

TVR's were originally simple. Mega performance for potentially normal car running costs (steel tubes, fibreglass and standard engines - simple cars). Having gone off on exotic tangents with their own engines it seems predictable that some people want modern interpretations of the simple performance of how it used to be. When people have posted as to running costs of TVR's, its been said that AJP Cerbs have potentially double the running costs of a RV8 car.
LS Powered Cerb would be much closer in running costs to RV8 than AJP.
It can be seen as a compromise, but its the real world and people don't have infinite money to follow pure idealism. If they did have, am sure most would go for a redesigned AJP engine with 32v heads and dry sumping
and spend most of their time driving their car around on their private track only stopping to be fed pizza and caviar by bikini babes who would also wash the car and tickle your hairy chest. An LS is ALOT cheaper to run than an RV8, and obviously make ALOT more power unless you through stupid cash at an RV8 (or even an AJP) - (once installed just change the oil and filter regually and FORGET about them! - try doing that with something with chains or a cam belt) - i.e. they don't break. RV8 500's eat cams and have poor bhp/ltr as they are inherently a much older design pushrod engine.
Ooh and modern ferraris are so heavy it is just laughable. Even an old 512 will be pushing close to 1.5 tons! TVR's are much lighter an bet the best from what ever engine is in them. Griffs and chims start at about 1065 - 180kg my LS6 is about 1110 a Cerb is about 1200 - shed load lighter than most competition.

hmmm if someone offered me the choice of a bastardised cerbera LS or chimaera LS or a ferrari BB i know what I'd have. I'll take the uber cool styling and flawed dynamics of the BB every time thankyou 
Slow and Old and bad design - yes they are nice - but even new all road test soad there handling was Utter PANTS. Even the testa han the same crap engine / gbox layout just with more valves. Ferrari alway did lag behind when it came the latest technology - not now with the might of FIAT pushing it along.Anyway OT.
My standard griff is faster then my 512 but now we are talking straight line performance. Cornering is an other subject.
I used to own an 1964 275 GTB alu 6 c which i sold. This car had about 350 hp and still in a straight line the griff was faster. Due to torque. But on a track the ferrari would really destroy any TVR. Ferrari's weight was 1100 kilo. They use the car now in classic ferrari races like shell maserati - ferrari and so on. Paul Knapfield now owns the car.
And comparising ferrari's with TVR's is just stupid. We are talking about different levels of engineering. Ferrari's are beautifully build cars TVR's are light cars with big engines.
I love my TVR and i take it for what it is.
I can really understand your point that you want to change the AJP engine for an other engine. I am thinking of buying a cerbera too because i really love the shape and the AJP engine looks cool in the car. But perhaps when you want to use it a lot without any problems and so on converting to a Ls 1 option is the better thing.
When me and my brother(well knows ferrari racing expert in the Netherlands www.roelofsparts.com)worked on my TVR to get it to handle better we both agreed that it is a good thing TVR does not make their own engine because when they put together an engine like they do with the rest of the car it will never work.
My griff is a little bit like a kitcar which i think better to buy it in parts and build it up yourself then let TVR do it. But i love TVR's but please do not compare with ferrari. That is just not honest.
