I realy dont think the 7 is going to work for you.

If you make the car 300mm wider then unless you increase the track ( which would mean longer driveshafts ) then your wishbones are going to be incredibly short or a very very odd design.

The height at th front is also going to be an issue, you need to keep the drive shafts as level as possible to avoid undue strain on the CV joints.


If you want 4x4, then use the Ztec engine but use sierra running gear.

I'm guessing he is using the Zetec out of his 4x4 Mondeo? Also it will have all the suitable driveshafts, if he's using the Mondeo as the donor. Personally I think its going to look exceptionelly ugly. The wide Luego looks like a joke and thats quite wide. 12 inches wider is going to just be against the ethos of a sports car.

Luego Vs a Locost

Also. the mondeo shafts run in line with the back edge of the engine. So with the driveshafts in line with the hubs would mean the engine is sitting in the front frame at the nosecone, this would probably put too much weight over the front of the car.


Look at this picture and imagine the engine being turned 90 degrees and centraly located where the front rails are. That's prety much where it will have to be.

I thought the Mondeo 4x4 used the MTX75 Gearbox with a transfer box? So the engine has to be dropped in sideways, which is probably why he needs a chassis 1 foot wider.

TBH I don't see the point getting it all in, only to have less power than other engines, and weigh 200 kgs more. With all that extra chassis, driveshafts and transfer box.

Sorry, just edited that to clarify.

Engine forward and rotated 90 degrees.

YEs it's the MTX75 with a transfer box of the diff.

i think its ambitious if i wanted a 4x4 7 i would use the gearbox and front diff and hubs off a 4x4 sierra. you would then have to move the front dampers forward so that the drive shafts would clear. something like the mk indy R front suspension design would work.

personally i think is a bit of a waste of time using the zetec as it doesn't make enough power to warrant 4wd.

i dont really think 4x4 fits the ethos of a roadster is there a particular reason you want 4x4 or is it just for the challenge of doing it? i can tell you before you start that a standard roadster will run rings round it all day but i doubt that will put you off.

what im not going to say is dont do it. if you think you can pull it off then i personally would like to see.

I suspect it's the old "I have a donor to use but it's a....." reason

Personaly.

I would flog the Mondeo 4x4 stuff. Buy a 2.0 XR4x4 Gearbox and diffs. and do it that way. the Zetec will bolt to the MT75 box.

I am not stuck in my ways,

I converted a 1.8 RWD sierra to 24V V6. and 4x4 with ABS.

I have converted a 1.1 Carb Golf to 1.3 EFI

And converted a FWD golf to Full IRS with longnatudinal engine..


there are only 1 or 2 4x4 Sierra based Roadsters neither of which I think are IVA'd, so it's not been done to death.


If you realy think it's a goer, then post up some pics of what you think it's body is going to look like. Are you plannign a 7-esq or full boddied car?
