Using a Ford 2.8i V6 from a Sierra 4x4 in a Locost
mackie - 8/9/03 at 02:41 PM
We got it running yesterday and it seems a shame to chuck it...
I know some people have done it so I have a few questions.
1) How much does it weigh? (one of our plans is to use a Rover V8 which is almost certainly lighter but we don't own one yet and we do own the
V6)
2) How easy is it to convert to work with a rwd gearbox? I've read about the input shaft on the V6 engines being longer than 4cyl so I guess that
has to be modified and obviously the sump will need modifying. Anything else?
3) Is the EFI a bitch to install or is it just just more wiring and a return pipe?
4) Does anyone have a spare MT75? 
5) Can you use the standard 'zaust manifolds? (my impression is no, unless you want toasty feet)
Cheers,
Mackie

1.)Don't know about weight, but use it 'til you find/sort a v8?!
2.)the v6 type 9 does box have a longer input shaft, just find one from a 2wd v6, granada might be a good source. Making it RWD is simple, just bolt
on a type 9 (with correct lengh input shaft) or an mt75.
3.)Inevitably more wiring as far as i know
4.) no, sorry
5.)don't know
ChrisW is building his viento with a 2.8/9 v6, he's just sorted his gearbox out too i think, try u2u or emailing him if he doesn't post on
this thread....

My car has a 2.4 cologne v6 which is the smaller one of the 2.9 range, which effectively is the same engine as the one you have.
1. According to the haynes manual, a V6 car weighs 65 kilos more than the pinto equiv model on the granada.
2. The V6 is used with a type 9 (NOT MT75) which has a longer input shaft. When I looked, the 2.9 cars with manual were rare, which is why I ended up
with a 2.4 manual - as the 22.4 I saw (2) were both manual.
3. EFI is SIMPLE to install.
You need to mount the pump and filter at the rear of the car and as you say, have a return pipe. On the granada I had, the EFI loom comes out seperate
from the rest of the loom. You just end up with a 9w plug to sort out. I can give you details of where this goes. The efi loom contains everything,
inc the pump relays etc. My car started first time.
The biggest issue may be the height of the plegnum chamber - these seem to vary in size and shape. It makes the engine fairly tall.
4. Use a type 9 - not sure if the MT75 was used with the V6 - someone will let you know tho!
5. I used the std manifolds. However, there seem to be lots of different styles fitted. The driver side one on my car exits quite high up and makes it
really hard to fir the top chassis brace.

Cheers chaps.
I can't spot the fuel distributor on your installation stephen, where is it?
Our engine looks a little different to that with the air pipe going into the right side of the box shaped plenum. It is pretty tall but probably no
taller than the V8 with the twin SUs. It seems much more compact in width though.
Tis worth considering certainly. I think blueshift is still set on a V8, and I am too, but I am also keen to keep it lo-cost
[Edit] Doh! Ours is mechanical fuel injection, hence the distributor!

You need a gearbox from a RWD v6 car. The 2.8 Capri sprung into my mind but the XR4 (and probably XR4i) used one as did the rare Granada v6 if you
can find one in manual!
You'll also need a RWD sump but these are easy to get hold of from the far more common auto Granada v6. You could weld the holes up in the 4x4
one but it's a lot of hassle (it's alloy remember!)

Easy peasy if you get the complete loom from the donor (unplug it behind the dash). You need to hook up about 6 wires and run a power feed back to
the fuel pump as the injection system turns it on and off as needed. Tank needs to have return lines and a swirl tank, either integrated or from an
XR3i.
Remember to get the fuel pump from the donor!!

the manifolds are different on each side as one has to clear the oil filter. I'll let you know when the engine is in (hopefully tomorrow!) if
they look suitable. You can swap them round (left to right or upside down) so if space is a problem I may put them on backwards. Even considered
finding another car so I can have both the same - might make life easier as one has quite a nasty down turn in the end. We'll see...!

BTW here's a diagram I did of the v6 input shaft for a chap who was trying to sell me a gearbox. Might come in handy?
Got a mate who used to rebuild type 9 boxes who reckons it might be possible to build a hybrid box from the XR4x4 front and a normal type 9 back. In
the end I decided it was too much hassle and bought a 2nd hand box but if you get stuck I could have a word!

The 'EFI' bit I so nicely picked out in red and silver was the clue 
Your system must be MFI
Bet the doors dont fit and the drawers fall out

As 'V6 type 9' boxes are hard to get hold of these days (especially round here which seems to be the scimitar capital of the world!) here is
a cunning plan:
Get an adaptor made (photo and dimensions to follow) that bolts onto the flywheel with the flywheel mounting bolts and moves the location point for
the end of the input shaft forward for an ordinary 'type 9' box.
It is a trick used by an aquantance of mine when replacing the original auto boxes in scimitars.
The part is not comercially available as far as I know but is a relatively simple piece of machining and even if you pay someone to make it for you it
is still cheaper to source a bog standard 'type 9' and have it made than source a 'V6 type 9'
