4 litre V6

[phillpot]

Seems like there was a thumping great big 4 litre version of "our little 2.9s" used in some American Fords. I imagine extra capacity gained by longer stroke rather than bigger bore ( maybe bit of both ) ? Wouldn't exactly make it a high revving screamer !

Anyone know of one of these finding its way into an S ?

[S2 Giles]

There are a few Cosworth 24valve versions of the V6 kicking around in S' Series cars now, however the only person i knew who was looking at dropping the 4.0V6 in was "LeeBee" Lee Boreham, but i dont think he ever got round to it.

It was in the Ford Explorer 4x4

I think the sump has to be modified, and a few other bits. Plus the hassle in finding one, and may be harder to get bits for. That's why I never followed this route, but don't let that put you off.

I think they are rated at over 200bhp in stock form (well with the S induction and exhaust system) but the torque is fantastic, thus giving a good tuning potential with a cam change and head-work.

I'm sure somebody has made an engine using a 4.0 block with 24v Cosworth heads before.

What you really need is a supercharger

[phillpot]

12 valves plenty enough for me, but 4000 cc ? ?

[The Lukas]

To be honest, I would rather a 24v 3.0 V6 than a 12v 4.0 v6. Fuel economy is better, and plenty of room for for more power. Generally the more modern, efficient and powerful engine I deem and can be twin turboed with fantastic results! IMHO

Bit of info for you, could'nt find anything TVR though.

Perhaps I'm old fashioned( no, I am old fashioned) but no substitute for cubes ! !

somebody has done this, i remember seeing pics and description of the transplant on the net

It lead me to this on Wicki
"Capacity increases
In 1991 increased capacities for the 2.8 and 2.9 engines (3.5 and 3.7 liters, respectively), were first developed and introduced by D.P. Davies and sold by his company, VeeTech Engineering, in the UK. Two companies still produce large capacity conversions on the 2.8 & 2.9: Power Engineering and Specialised Engines.."

I'm pretty sure the 4.0 V6 is also in the current Ford Mustang.. get an engine and box shipped from the states..

Also there are some pretty good looking SC kits for that engine too.. oops just spent the best part of £10K lol..

I'm going for 24V as it was v cheep.. still need the Mustang gearbox though..

hi i went to pick up a petrol tank from a guy in amersham he was building an engine using the 4 litre explorer block and the 24v cosworth heads i saw the flywheel he had made up and seeing his other mint and very detailed tvr,s and his fully equipped workshop i would imagine he completed it this guy is a serious engineer problem is i cant remember his name

Engines can be picked up cheap enough but from what I've seen on Ebay gaskets and other bits 'n bobs can be pricey. And custom made headers ? ?

The 4.0 does have a slightly wider block so you have to modify the sump and you also have to make sure you get a 4.0 with the right crankshaft as the rear needs to be compatible with your flywheel iirc. It's not a great performer but there are a number of very serious 4.0 24v conversions under way at the moment. They would be very expensive but the individuals doing them have engineering facilities and are doing it for their own pleasure. Forced induction on a 2.9 would probably be a better bet be it 12 or 24 valves.

[johnnywgk]

What about forced induction on the 4 ltr, hehe just a thought.

[kenpage]

mike as i remember it he had to have the flywheel made because the crank was an 8 bolt if that makes sense

[Boosted LS1]

Yes, that makes sense as iirc there are 3 different explorer cranks so he may have started with the wrong engine or crank in the first place. Mind you, if you want a pukka custom flywheel the the cranks no big deal.

It'll get good towards the end.

Yes. he used to post as Mickeypee, but I can't find that ID on here anymore.
