fwd donor
does anyone know of a way of using a fwd transverse engine for rwd, keeping in mind if i turn the engine through 90 degrees it is running backwards,
is it possible to just flip the diff?

get a rwd gearbox that fits! thats how we all do it 
how many ford zetecs or duratecs were rwd? none i think. i don't think ford do any rwd cars now, yet theres plenty of zetecs and duratecs in
peoples cars here
or am i missing something?

nope. all engines run the same way, except some Jap angines. honda s2000 i think? vauxhalls, fords etc, all go the same way. i've got a vauxhall
enigne with a sierra gearbox, and capri back axle, and its all good

Most all current engines rotate the same direction these days.. Even Honda's :-)

Certain engines do run in the wrong direction, civic type r for one. But zetecs dont', simply turn it 90, mate it up to a rwd box and away to
go, well of course its not quite as simple as that lol

there is an answer for any fwd donor - build a car with a mid-rear layout, then all you need to do is move the whole thing to the back without turning
it

ah, right, didn't know you were using a honda engine lol. what about a s2000 diff? that would work the right way for you
not sure turning say a sierra diff upside down is ideal. might work. would need a few mods (blocking breather, and making a new one. got a feeling the
diff effectively running in reverse all the time (the input flange will be running the wrong way than it was designed to) it will wear out pretty
quick...
think a rwd honda diff is the best way

My Zetec certainly runs the correct way as does the S2000 and most others Im sure its only the type r which is a problem hence it being fitted in the
rear of the Atom so no problem with rotation

I think the S2000 engine turns the right way (unlike most honda ones) it designed for rwd and its still a vtec

i do like the whole engine backwards idea saving a shed load of work, been thinking along these lines originally. just wondering if anyone else had
used a honda h22a engine in rwd layout

yes, but as far as I know only in a midi with its own box
think of something like a car engined version of the new MK midi
or as far as existing kits go both the GTM Libra and marlin 5exi use honda fwd as donors...

You could always put the honda engine in the back, turned round, fit a prop to the front and use a sierra diff which would give front wheel drive but
in the right direction.

Easiest way to tell if it will run the right way for rwd is to open the bonnet... if the gearbox is down on the right (most fwd cars) it goes the
right way, if the gearbox is on the left (drivers side) it runs anticlockwise aka Rover 416.
All Ford engines run the right way and bolt up to a type 9. Apart from the Duratec which came from some where else....

Build a midi. Have a look at my build pages below which are for my Mojo build. This takes the complete engine/gearbox solution from a FWD and
puts it at the back. Simple, and good weight distribution too.

found a site in usa bout a guy building a lowcost style mid, this is what got me thinking of using my honda vtec engine, looked real cool. but this
left me with a couple of problems, i was originally thinking of buying an older - sva'd kit and modifying it to take the engine. didnt realy
want the complete build option. the second problem is i cant shake the image of that american build out of my head. and now just to make it worse,
ive seen yours

Thing about midies is if the rear suspension is from a fwd donor it takes a great deal of attention detail to design out bump steer & roll
steer.
Anything that will mate to a Rover PG gearbox is easy to convert to mid installation as Rover MGF & MG TF bits will adapt the gear change, the
other simple way is choose an automatic donor.
