A bit more googling shows what I mean...
You can see that for starters the engine is going to be shorter than a bike engine because its only 2/3 cylinders wide so even if this transaxle would
fit the bike, you'd already need to find more room up front to get the driveshafts back in line with the wheels.
On top of that the driveshafts come out immediately behind the clutch (which is roughly where your bike engine output shaft would be. If you imagine a
normal diff in place of the transaxle, the driveshafts will come out near the back of the casing, not the front, so you'd probably have to move
the engine a good 30-50cm further forward than the current engine to claw back the space needed to get the driveshafts in line.

where u say the driveshafts will need to be if the bike engine is touching the radiator is about where they are on the saab, there is not much in it.
deffo room if i move the radiator.
with the zetec installation i am doing the engine will be right up against the front panel. meaning i have to move the radiator behind the engine,
this has been done before with v6 conversions.
if needed would a radiator be ok behind the bike engine? how much cooling do bike engines need? more than a ford essex v6? there will plenty of
space.

Must be an optical illusion or something then because looking at the car from the side, the front wheels seem quite close to the front of the car, and
I can't imagine the current driveshafts being that far back!
Just thought though, you said you were using the Triple so ignore some of my comments from above about the length of 4 pot engines. At the end of the
day though without some measurements its impossible to say, but I strongly suspect that any bike engine with diff hung off the back will be longer
overall than the current setup with transaxle, so it will need some measuring up to see if its feasbile. Also you'll need to look at the height
of the gearbox output on the bike because as well as too far back, it might also position the diff too high making the driveshafts run at silly angles
downwards
cheers

shoot, i just got what u meant about the driveshafts coming out further back along the diff. is going to be a tight squeeze, how long is a bike engine
and gearbox? a typical installation at least?
am trying to remember how long the zetec was? if the bike installation is the same or shorter than a zetec then it will fit, if not then prob not.

yeah it is strange how far back they are, they aren't angled up or down by much, will have a look for the triumph triple engine, does anyone
have a decent pic of an installation? like u said u really need to measure it to make sure.

Ive not measured it personally but an R1 is evidently about 55cm wide overall, ie front to back in the way we mount them. Guessing at how long a
Sierra diff is to the centreline of the driveshafts, about 25cm or so. On top of that you'll need some kind of small prop or cush between the
engine and diff to join them up, so overall you're not far off needing a metre from the front of the engine bay back to the front axle line.
A triple will probably be shorter than the R1, but not by a huge amount.

i can't recall how long it is from the driveshafts to the front of the car but a metre is definatly pushing it, i think gonna be a prob to fit
in the space, not suprising really.
oh well will have to dream about it some more!
many thanks for ur help chris

No probs, don't just take my word for it though cos all those measurements above are only guesstimates and in addition to that, Ive never seen
inside the engine bay so get your tape measure out, you might be suprised!

i would of got it out and measured if i was living with the car, its at my parents house at the mo and i am at uni! i am in southampton and i come
from runcorn, its the town next to liverpool. if someone could tell me how long the truimph triple engine with gearbox is that would be great!

have been thinking about when i offered up the zetec, measuring from the gearbox to the front of the car it was 54 inches. i think i am right, will
have to get it confirmed but that is over a metre! 1.3 metres or so. so it looks like it could be possible after all!

I assume thats to the back of the transaxle though, as opposed to the front axle line?

its from the front of the gearbox, i measured it from there as i was offering up the zetec, it will be mounted to the orginal transaxle. so if
anything i could add a few inches to that.
