2.5 V6 Question for Razman
jamesg20 - 6/2/07 at 03:05 PM

I'm seriously considering using the duratec V6 in-line for my new project. Previously there has been one discussion about using a transit bellhousing to mate the mt75. Has anyone done this or, or able to put me in touch with someone who definately has? Or alternatively anyone who has used a T5 or anything else with it.

Anyone modded a sump for in line use?

Also (i'm hoping RazMan can help here) What ecu, induction and loom setup have you used? I'm wondering whether the standard ecu can work without all the immobilisers and junk attached or did you go aftermarket?

There seems to be a lot of heresay with this engine, but as yet i'm struggling to find anything concrete!

Mucho appreciated as usual.

james.

There is an american gearbox, from a Lincon I think. There is a website with someone building a twin turbo duratec v6 and putting it in a rwd mk4 escort.

Do they MT75 and MTX75 (FWD) boxes have different bolt patterns?

Burton power are starting to produce a lot of duratec conversion kits including bellhousing to mate to other ford gearboxes

The reason I ask about the MTX75 is they use it for the FWD Zetecs and don't they mount straight to a type 9 box?

The Duratec V6 uses the MTX75 in the ST24 so thinking logically wouldnt the type 9 fit the V6?

Of course it may not work as simply as that.


RazMan - 6/2/07 at 04:57 PM

As far as bellhousings are concerned I'm afraid I can't shed any light on that subject because I just used the standard MTX75 transaxle in my middy. Sounds like the Type 9 might be worth a look though.

The ecu is another story The oem ecu was looking like it was going to be difficult as it didn't like being forced to work without all of the emissions and security stuff so I cut my losses and went aftermarket - I used an MBE ecu with a custom engine loom. This choice was guided by the fact that MBE already had a base map for the V6 and the software was pretty straightforward to tinker with.

The induction side was fairly straight forward although I removed the secondary butterflies in the LIM to improve breathing. They are normally activated by the ecu at 4000 rpm to improve torque in the lower range but in a light car they are largely redundant.

Hope that help - if you need any more info you know where I'll be

I thought the only rwd box that fitted was out of the Jag? I looked into this a while back, and it appeared that the V6 used a different bolt pattern. Also if it does fit, can it handle the power/torque of the V6? I know it was fitted behind the old V6's, but the new one is a lot more powerful.


greggors84 - 6/2/07 at 09:48 PM

Standard ST24 170bhp and 170 lbft (roughly).

Even if you upped the torque to 200 lbft, whats the limit of the type 9?


ned - 6/2/07 at 10:27 PM

type9 would not last long at all with 200lb/ft imho. also the st200 and st220 are more powerful than the earlier st24 and without the restrictive inlet/emissions/proper exhaust will make a few bhp more than book. Raz's standard engine on mbe made 210-220bp iirc and plenty of torque.

Raceline do bellhousings for the 2.0 duratec so that you can use the type 9 and I'm sure the guy mentioned that they did them for the 2.3 they are on 01483811978.

This is all sounding tempting. Razman, what spec of engine did you use? The ST24 are pretty easy to find whereas the st220 etc's are rarer than the preverbial rocking horse poo...

210-220 off a standard engine with ecu sounds tempting, especially when they can be had for good money. I've sent power torque an email ref bellhousing, but i'm not expecting it to be locost... I'm still interested in anyone who can shed anylight on rwd gearboxs that have been used. Anyone know how i contact the dutch westfield guys / how they do the install / any pics? The sump could be another limiting factor, both clearance and suitability. I can't afford to dry sump it, unless of course there is a locost way..!

As I mentioned earlier, the ST24 can be modded easily with SVT stuff from the US (their Contour is our Mondeo) so 220bhp is easily achieved. I just need the bigger TB to get the most out of mine now as I have already fitted the SVT upper & lower inlet manifolds & injectors. Cams are also available and then there are the supercharger kits ..... just depends on the depth of your pockets.

Oh and lighten the flywheel too - much revvier then

Hi James,

Like you I have been tempted with a Ford V6 engine. I did a bit of research about them; findings: relatively light ( installation for locost should be about 177 kg inc gearbox versus 146 kg for a Duratec inline 4 ), power as advised by Mountune would be 285+ bhp by running aftermarket ECU and changing the exhaust header on a Jag 3.0L V6... that is plain silly in a Locost, Gearbox = Getrag 221 for the Ford/Jag V6 as used in Jaguar S-Type ( ok ratios and a light and quite small gearbox ).
I can source you a new Jaguar engine for big $, or if you want I can get either a new or good second hand gearbox for reasonable money.
PM me if you want to know more.

Mark

Ford fit the 2.3 Duratec in the Ranger truck in the US. Uses the Mazda M50-R1 gearbox - same as the RX7 turbo (big brother to the MX5 gearbox).

As long as the V6 Duratec has the same bellhousing bolt pattern as the I4 Duratec, could be another option.

The getrag 221 is the rwd gear used in the lincoln ls and the s type jag (3l). The gearbox internals are mostly form the manuals used in BMW M3. The gearbox won't directly bolt up to a Duratec 25 V6. There are several holes missing on a Dura 25 and some of the holes in the dura 25 are shifted 1 or 2 cm. I will post some pic's later on. This issue is, I suppose only for the st24 and the st200, cougar v6 (using a dura 25). The st220 and the jag are using a dura 30. The initial design of the duratec V6 was from porsche, went to cossworth and ended up in different cars (mostly ford related)
The st24 and the st200 are an easy fit from a hight point of view. The UIM is more flat compaired to the newer once.
