Can I fit the 24v Cosworth V6?

[mickypee]

Dear All, I am about to uprate my S2 by installing a 24v Cosworth V6.The trouble is they are pretty difficult to find at the right money.I am looking for a stolen/recovered Sierra or a high milage motor or a written off car.I would prefer if the electrics are included,i.e ECU etc.Shouls be a superb machine when complete as the rest of the vehicle is concourse. Reply here or email me direct.(mikepearsl@@aol.com) Mike

Oooh. top idea. I'd heard it was a tricky conversion (different wiring loom?). I know Tower View were trying to do such a conversion a couple of years back and to my knowledge still haven't finished it. How much power does the 24v unit have?

[mickypee]

If its set up correctly, anthing from 240+bhp.Perhaps not quite Griff perfomance, but should be fun. If anyone knows where one is, please let me know. Thanx Mike

As far as I know the 24V Cosworth was fitted to the Granada Scorpio and not the Sierra, there are also 2 different types, one with 190BHP and the other had 210BHP (maybe slightly more if you disconnect power steering pumps etc).You can find complete cars for sale at around £3K but they are usually very high mileage due to the fact this is what they were intended for.Be warned if you find an engine that is "only" missing a few little black boxes make sure you know what they are going to cost you as these engines are not cheap! (eg bare cylinder head £1,500 each!).I looked at this conversion a while back but was warned of clearance problems so decided to look at different options.Also consider that the 24V Cosworth engined Granadas were automatic so the ECU will have to be reprogrammed to compensate for this and a suitable gearbox/bellhousing will need to be sourced, this is not a straightforward swap!

The car that you will be looking for is not a Sierra as they were never fitted with the 24v Cosworth V6, the car you will need to find is a Granada Scorpio Cosworth, as this was the only vehicle fitted with this engine, you should be able to find one for about £1000. There are a number of problems with the swap as I am most of the way through it at the moment and have come across them, they are as follows, 1. The Cosworth V6 only came with an auto box so you will have to use the manual box from your S, this is not a big problem as the bellhousing pattern is the same. 2. You will need to remove the whole engine wiring harness and ECU from your donor car, this is a big job and wiring it in is an even bigger one!. 3. And this is another one, the cast iron exhaust manifolds on the 24V will not fit and also face the wrong way so you will need to have a new set custom made, and the tolerances are tight!. 4. The Bulkhead will require a small amount of cutting and modification to provide clearance for the O/S head. 5.You will need to remove the air con compressor, air pump and the idler wheel as there is no room for them and relocate the alternator higher up as one of the new manifolds passes through it's old location. There are actually a lot more but it would take a while to list them all, but if you are still interested I would be willing to give any advice which may be helpful to you. Out of interest the 24v Cosworth V6 was used in the Supersport 3000 racing series where with new race spec cams and a fully mapped MBE ECU they made 300bhp as against the 200bhp they make in standard form. Good luck with the project, it will be worth it. Lee.

Lee you need to move further north as you can get a Granada Cosworth running with tax and MOT for between £800 - £1000 up here, I knew there was a reason why i never buy a car from that far South. By the way did you get any furher with the Idea of fitting the 4.3l Cheverolet V6 into your S?. Lee Edited by Lee J on Monday 3rd September 23:08

Lee J, Thanks for replying to my posting. I am very interested in what you have to say. Do you think you could email me direct on [e-mail] as I would like to chat to you about it but im reluctant to give my details on the site. What part of the country do you live in?, I would love to see what you have done so far. Look forward to hearing from you. Mike

[LeeBee]

Hi Lee J still thinking about the 4.3 but a 4.0V6 Ford is also an option (will take the 24V Cosworth heads ) as it is all alloy and has 205BHP /250lbs/ft torque standard and that's without a wealth of tuning parts that are available stateside!.Also considering a Hewland transaxle but I really don't know where the money is coming from!.Do you have any photo's of the conversion yet? as I would love some for my Technical CD Rom I am (still!) working on. Cheers LeeBee P.S Fiero GT eh? always liked those!

Lee J You have got to get some pics put on your profile I would love to see your Pop and Coupe. One of these days I might get off my ass and build that 350ci 1931 Ford Model A Paul

Can a 2ltr 16v Cosworth be put in? There is so much tuning stuff for these it would probably be easier too more out of it than the 24v. I’ve heard of silly powered ones, I friend had one up to 340bhp in a standard sierra shell, when he sold it he only got a few thousand, a lot of go for not a lot of money.

[LeeBee]

Yes go back to the late 80's and look at the S turbo, 500+ BHP nice but it got a bit hot (I still want it mind you!!).Now I may get slated for this but I don't think I would ditch a V6 for a 4 pot turbo motor however much power it had, in my opinion a turbo engine is no good without it's turbo whereas a nice V6 is so why not bolt 2 turbo's on it instead!, I once saw a Sierra 2.9i estate with the Turbo Technics conversion seriously blow away my mates RS Turbo (200+BHP) and this thing had a load of wardrobes in the back! You can't beat cubes blah blah....... Cheers LeeBee

4.6 turbo/super? It would be silly, but I have to admit the thought did cross my mind ... Peter Humphries (and a green V8S)

Hi All,
Good to meet people at the "S" meet last week.Much interest was shown in my car so heres the lastest thinking on the Cosworth mod.

I met a very knowledgable man (Pete) who has similar ideas to my own.I have decided to go a slightly different route in the form of a 4.0L V6 Cologne engine as found in the Ford Explorer.I think a suitable engine has been located.1999 model with only 18k on it so might get out of reboring it.Onto this short engine will go the Cosworth Heads, still fuel injected with the Cosworth Plenum.This should with a bit of tweeking and fettling deliver around 300bhp giving a "Generous" performance.

However, I am still having trouble locating a Cosworth engine, as I still need the heads and fuel injection electronics.Does anyone know of anyone with such a motor?

Looking forward to the next "S" meet.

Mike

Pete... hmmm. 300 bhp in a V6 chassis hmmm. If it is the same Pete as in Green V8S, I hope he mentioned the absolute small fortune that was spent upgrading everything else to cope with the power.

Diffs, gearboxes, drive shafts, CV joints are now consumables. If you budget on twice what you think it will cost, that will be about right.

Hi Steve,

Thanks for your concern with the conversion. It wasn't your friend but I here what you say.I was merely giving a progress report as a number of people are interested in what I am doing with the "S"(including the factory)Just to put the record straight, I have been doing this sort of thing for many years and have a reasonable knowledge about such matters. I have built and prepared many performance cars in my time, this one just happens to be for me.Hence my enthusiasm.

[PetrolTed]

I think Steve is also alluding to the fact that Pete has had to do a fair amount of research and development to keep the power train intact.

[petert]

Steve,
I totally agree with your concern(s) regarding such power - and torque - pushed through a V6 chassis. Looking to the care and diligence Mike has taken over his build so far, and respecting the use (or lack of abuse) that I'm sure Mike will apply to complete the build and drive, I'm confident all will be well.
I'm also sure you will agree there are significant additional strains imposed when sprinting rather than 'normal' road use.

PeterT (not with a Green V8)

[shpub]

I'm not getting at anyone... I'm am just pointing out that Pete H has gone down this route and has a lot of experience in understanding what the problems are and that a few minutes chat with him will help you immensely. The engine was the easy bit and he had the advantage of the V8S to start with which is an infinitely better base to start with.

As for the sprinting, it is actually less strain than a track day and many of Pete's failures have occurred on the road during normal driving. The car does a very high mileage and will find out every weak spot there is. As for building a car that has this level of power but then relying on driver restraint to hold it together is not a good idea. In my experience the insurance companies don't like it either.

Both Pete and I have very radically modified TVRs and have spent small fortunes on the development and engineering. We both hate seeing other people make the same mistakes as we did!

Happy New Year to you all,

Things have progressed with the project in as much as I now have a 4.0L V6 (9k miles and a complete 24V Cosworth engine)
Does anyone know the the web address of Burton Power? Don't seem to be able to find it. (Need a Flywheel!!)

Also, does anyone have a pair of V8S rear trailing arms new or in good condition?

Looking for a T5 gearbox to marry the whole lot together if you know of one?

Apart from that I think I have most of the other bits,just some spare time a lot of reading and an increase in the outside temp.

Mike
