Thoughts/advice on my proposed 5.0 build-

[Mattchim]

Ok so i currently have the 5.0 chim thats already had an engine rebuild due engine noise and found No7 liner and piston skirt broken.(30k miles) ,rebuild didn't include top hats. (another topic)

The engine is making noises again(48k miles) and though it maybe the common worn little ends i have decided to get it fully sorted via one of V8Ds engines once and for all rather than have a rebuild done to TVRs 5.0 again.
Main goal is a stronger , more reliable engine that i don't need to worry about breaking, especially when nearing the rev limit as i do love that sound.
I don't want to go LS3 or forced induction as i bloody love the sound of the RV8

I would also like more power, more responsiveness as the power doesn't quite cut it anymore though that may also be mix of me being used to it and also other issues from the above.
For use on A/B roads, occasional track day and touring though Europe.

Initially i wanted to go for a bigger engine ( 5.2 or 5.3) but after speaking to V8D they just cannot get the cranks at the moment.
So they have sent me a build spec for a 5.0 in line with what i want to get out of it though being new to this i am still not entirely sure what i am looking at .

Budget was about 8k but inflation really has hit hard these past few years because that isnt going to cut .I have upped to 10k that isn't going to include a new ECU.
Spec follows.

5.0L Top hat linered block
New Forged pistons
New rings
New mains
New big Ends
New cam bearings
New core plugs
Fully balanced assembly
Pocketing of pistons
Special grind cam (Spec to be finalised)
Special grind cam
Timing chain set
High rev Lifters
Running in oil and additive
Comp head gaskets
Comp head bolts
Recondition customer cylinder heads,
Vaccuum test
Lap valves
New stem seals
All required gaskets and seals
Adjustable push rods
Fully refurbished rocker assemblies
Fully refurbished rocker covers (off your original engine)
Fully refurbish front cover (off your original engine) including new oil pump gears and uprated oil pressure relief valve kit
Balance front pulley (off your original engine) -
Face, Lighten and balance flywheel (off your original engine)
Uprated clutch to take power of new engine (if required)
Water pump (if required) -

Polish and ported inlet manifold
45mm radial trumpet base
72mm larger bore plenum

So this now is just over my max budget ( at least if i still want to keep the wife) Drive in Drive out cost, i just hope they include any vat in their prices :-/ and the ECU will have to wait.
From the research i had done on prices i had hoped to be well under 10k or at least have larger than 5.0/ITBs/crossover induction for that money but i guess it was all based on the Pre Covid , Pre Money Printer GO BURRR days.

Brakes on the car are vented , grooved disks, braided steel pipes, Racing pads. Gaz gold suspension.
Body off chassis resto is the next on the list after this one and i will look at bigger breaks then.

Thanks i will make contact before continuing with the V8D route. i had really liked the look of the JE Induction system. it is sexy as hell.

If that V8D engine isn't enough for you I'd recommend another car!
A bit tongue in cheek that comment but I think anything more than that would spoil the nature of the car, my guess is that the difference will be night and day to your engine.

I think maybe you missed my intention with the post. It's not that this V8D engine is not enough for me . It's more that I am not even that sure what I am buying 🤣 .
I am very attached to this car so I just want to make it the best it can be.

I am not looking for crazy power just a little more than what TVR said it should be + much stronger and the ability to be thrashed now and then without breaking and needing a rebuild every 20k.
Something that revs like the 4.3 with the grunt and torque of the 5.0 would be a dream.

I'm sure the quality is up there but JE is very expensive and he won't remove/refit the engine either so you'll have to factor that as separate job/cost

Perhaps not then as the current cost of 10kish is making me wince a little bit .☺️

I'm not really sure what you hope to gain by asking on here though, surely if you want to know exactly what you are getting for your money you need to ask v8D ? But you've got a pretty comprehensive list from them already of what's in the engine, so I'm not sure I understand exactly what you want from the replies ..

I guess what that list corelates to as complete package and feel from the engine as a driver. perhaps from others with similar builds in their cars.
All of these parts don't mean allot to me in regards to capabilities and limitations.

For example i am quite into my Computers if i listed my Top spec PC hardware for VR/Racing Sim gaming to someone that doesn't know much about computers or VR technology would probably have no ide how that translates to refresh rates, details, resolutions, motions and capabilities at field of views, and ultimately user experience verses a lower end PC.

There are a few people with the 5.0 V8D engine on here, maybe you can meet up with them and see how the engine behaves to give you an idea.

excellent idea. i was kind of hoping to find some with this post. i shall do a search however from experience this forum isn't as active as it was 5/6 years ago.

The Facebook group is well worth joining to be honest, it is really good for this sort of thing even if you don’t don’t usually like it.
It’s a very active group with almost instant answers to most questions.

Is that the Chimaera Enthusiasts one? i had de activated my Facebook along with all other social media as when something is free you are usually the product....

However i have just reactivated it and signed up to all of the TVR pages

I also have the V8D 5.0 engine, similar to the spec you are being offered, mine was built in 2014, originally it was putting out 325 bhp, and since then I have supercharged it, now producing 474bhp, no issues in all that time

Ooof 325 wasnt enough for you :P what kind of torque pre super charge

Small update on thoughts. i have changed my mind on doing the 5.0 V8D engine. i think if i had anything other that a 500 chim it would be a no brainer. However i don't really like the idea of losing that grunt motor boat long stroke engine along with the cars engine code. It may not be perfect but its the heart of the car.
i flushed through the oil with some snake oil additives, filter change, went back to 10-40 semi oil that Powers reccomend with their rebuild and although the ticking is still there on idle i cannot hear it when i am driving and the engine feels to be running much better.

I think after reading this thread https://www.pistonheads.com/gassing/topic.asp?h=0&...
I will first look at having the tvr 5.0 rebuilt properly to see if they can do what ever possible to minimise TVRs f*ckup. Potentially take it out to a 5.2 , something joolz suggested as an option.

If only the 5.5 cranks were available as i think that's the only upgrade I would do involving a change of engine number.
