I need to identify if my engine is a TVR 5 l or the V8D 5l with the shorter stroke and larger pistons .

Could i Identify from the outside of the engine which one it is ? The reason for this query is because the crank hit my new melfab sump .Would the v8D 4.6 crank still catch the sump ?

Am i right to say the v8D 5l is actually a cross bolted 4.6 engine .

I need to find out before i move on to bigger numbers cool

The engine builder did not supply me with a build sheet ,that`s another story .

I thought you got your replacement engine from V8D? Is it not the large journal, overbore hybrid? I'm sure V8D would know. Have you asked them Daz?

Yep, they should have some build sheets etc Daz,
The engine builder should be your first port of call,
Hybrid ?
Sounds interesting !

As far as I'm aware and I think, (some time ago) it came up in conversation with Rob that yours is one of his specials.

Out of interest, my crank doesn't foul the Mulfab sump.

Take a plug out. Stick some sort of rod into the bore onto the piston top and turn the engine over and measure the stroke.

TVR crank has 90mm stroke.

I don't think its the crank itself that fouls the sumps, rather the big-end cap assembly...

4.6 blocks have casting opposite starter for the crank sensor to protude into the flywheel ~ blanking cap fitted. This is not on 3.9 era blocks with small journals.

No build sheet ,would a TVR 5l make the same power .

How do i turn the engine over ?

What is the difference between a 4.6 and 5 litre block ?

Undo the engine mounts and give it a little flip...

the standard TVR 5 liter is not crossbolted. V8d gets 5 liters with a bigger bore around 95mm and the 4.6 crank and crossbolting

Indeed, QBees is a standard 5litre but that was a conscious decision to go for that one.

Yours is I'm sure a Rob special.

Can the Tvr 5.0 l be cross bolted,, why didn't they do it from stock?
If the Tvr 5L has a weaker crank isn't Robs engine the best solution.

Who designed the Tiv 5 L engine.
Can you get a new crank for one or are they getting hard to get hold of,,,

I'd have thought FI will be to much for the Tvr 5L engine but yours Daz,,, a flier,,, go on boy, if you do it it'll start a trend..

Its not that quick ,a standard 4l with a Turbo bolted on is quicker .

I got a real good deal on the engine because someone put a big deposit down then pulled out .

Yours is very quick for NA Daz, (not as quick as mine of course) smile

Of course a 4.0 Turbo is quick but a 5.0 Turbo is quicker. Big is best.

Yeah but a 4L has better balance so with FI it's a flier,,,
Surely yours being a bit special you could get 400 bhp no bother.
Imagine.

My engine seems ripe for FI, fresh internals, what is it about 5k to get fully set up and no holed pistons etc,

The more I think about effing Chassis repairs and body lifts, the more I think, in for a penny,,,,,
Might aswell get the car 21st century fast.
There's something very soothing about the idea of 400 + hp.
463bhp that seems just about right,,

With all these super quick euro and jap cars about it's the only way forward,,

I can't quite imagine the Tvr going like my old 250 cart but now it seems possible!!!!

It's like space this tivvin,, never ending search for a faster way of life, lol.
