MK1 or Mk2 Stag V8 Engine

[Branyster]

What is the Difference between a Mk1 and a Mk2 Triumph Stag V8 Engine ?

How can I tell which one is which ?

Is a Mk2 Engine Better ?

Engine number will identify the block, but bolt on parts such as heads and inlet manifolds could have been changed so you could have a mixture of parts as some do.

Does the Mk2 have Bigger / Faster Bits inside ?

Have You Every Rebuilt a TV8 engine before Chris ?

[Branyster]

Engine No. 2 has this Number on the Block. LF12392HE

Go to the SOC home page Nick and click on the link "stag's history" (top toolbar)

This gives a rudimentary explanation.

Meanwhile I'll try to locate the other link I have that will give you the finer details.

Not really except the Mk2 had a higher compression ratio; but not necessarily now as many have had lower comp pistons fitted.

Have You Every Rebuilt a TV8 engine before Chris ?

worked on many but only one full rebuild Nick.

Try this one Nick.

Don't worry about MK1 or MK2 they both will break as sure as the spring will follow the winter.

Especially if Kermit the frog or Miss piggy builds the engine .
Many are still about even after being built full of casting sand .

and many still have the same engine fitted by the factory when new.

Dont tell him but all machines break sooner or later ;-)

Yours on the road yet?



Seriously though Nick difference between a decent mk1 or 2 engine compared to your dead unit will be huge.

Any idea if your engine is the one fitted when your car was new? If it were i might chose that as my rebuild candidate :-)

Well, trying not to start a rebellion - but I deliberately bought one with a RV8 - and am finding apart from never overheating, the very few spare parts I have needed - invariably ancillaries - are so cheap and readily available simply because they have been used on so many other motors - TVR, Morgan, Land Rover and Freelanders etc. Never had any problems getting spares from a multitude of cheap sources. (Now I'll duck and run).

Stand by your convictions man!



I went out of my way to buy a TV8. I love the RV8 in my range rover though. Had one in my p6 also, peach of an engine that puts up with serious abuse before failure.

My first range rover slipped a liner. They do that donchano! i k sealed it and carried on, it failed again so i removed the heads, skimmed them, this is when i found the slipped liner doh. Bolted it back together and ran it. Did nearly 40k miles on k seal with it like that. Then it popped the cooling system under excess pressure, dumped all the coolant but by the time i got to the hard shoulder it had seized. After it cooled the damn thing started again. Sounded like **** but it started and ran, probably on 5 though. That car was a nail though so i bought another, that has done just under 100k mainly on lpg under my ownership. No issues at all.

Efi bits are beer money, that would be the first thing i would do with a rover engined stag hotwire system is so simple to work with.

Sound wise, different noises but only the tv8 makes the hairs on my neck stand up when pressing on. As nice as the rv8 sounds it is no match for me

Btw freelander with rv8 would be some machine but they never made one

Hello Richard The Stag !

No idea if the Engine in my MK1 Stag is Original or Not. I'll know more when it comes out. Even if the Engine Number matches the Log Book it's NO proof it's the Original Engine.

Heritage certificate will confirm, you got one of those yet?
