Would it actually be a good idea to mount an engine in the back and have a rear wheel drive set up in a small hatch like a Nova. Surely the back would want to catch up with the front as soon as you put your foot on the brakes?

Depends on weight distribution etc. If you have bigger brakes at the front the car should nose dive and transfer the weight to the front wheels to allow them to do most of the braking.

Front mounted chasis arent designed to have engines put in the back so id say no, the car is built for the engine in the front, as soon as you move it, you alter the stress you put the chasiss under, handling will be effected significantly.
Thats not from experience but common sense from working with cars.

rear will need new section welding in.
boostbeast nmova used box-steel to cinstruct chassis extensions/reinforcements/etc to mount rear engine, but was also based on cav front end, so track-width was also widened.
car will be one seriously arse-out happy fooka which will be one hell of a bitch to drive, but ultimately serious fun & very fast
i cant remember the boost-beast site, but they had shot-by-shot progress pics (allthough not too great detail) of modification/fitting of rear parts & engine, so may be worth lookin for the site

i actually looked at welding the front end of a corsa in the back of another, measured it all up & it seemed ok to me for it, but its just the fact the rear would also need some serious re-enforcement to fit that made it a bitch.
integrating it with a weld-in rollcage will help a bit, but not ideal.

nooonononooo
the front chassis legs & mounts, basically the rear of the corsa has the floor removes & then is lowered onto this. reenforced with box-steel chassis bits...
like the boost-beast nova, but saves having to widen the track-width of the car

Me thinks people should read the title, no offence but welding the front of one into the rear of another.
Depends what you mean by "a good idea",

ok...
from what I have read into & understood about how they mounted the rear engine in the twin-let'd nova...
used CAV underpinnings & mountings for rear engine.
cut rear floor & suspension turrets out from nova
created & welded in box-steel chassis extensions/strengthening
welded in cav underpinnings
made it like a lil 'box' by looks of it
i was lookin at the same, but using the corsa underpoinnings/mounts instead

I've been in the nova with two engines, and its certainly a different driving experience!
IMO, you couldn't make a car with a wheelbase that short RWD, it would be difficult to catch the back end. 4wd only for me!

This is how Boost Beast Nova is done. How else you going to get the mounts in the right place? Lots and lots of fabrication? I'd use the existing legs myself.

Hence the reason why only people who know what they are talking about should be reading this thread...
Just realised that there is some hillbilly grass track racing thing that takes place in muddy farmers fields and quite a few people drive rear engine Novas... The handling can't be too bad, mabye a little colourful though.... Hmmmm....

No, I was commenting on how combatvauxhall decided to comment on how it was stupid to weld the front end of a car to the rear of another car to mid mount the engine and gearbox when he clearly knows nothing about this kind of conversion.

A guy called Ian Jemison used to rally a RWD Nova in the forests, it seems to handle well from the video I have of it.
As said above, you do need a lot of structural cage in the back to stop the engine twisting the shell. Best make a space frame at the back and then lower a shell ontop.

Was thinking space frame... Or going similar to what the Boost Beast uses, which is basically a rear space frame attatched to the monocoque shell using a roll cage...
Was this rally car rear engined though? Cos I'm thinking that when you put the power on round a corner the back end is going to be very twitchy and want to step out too fast...
Now I'm thinking 4x4 rather than a RR.... That would probably hand pretty nicely

i would of thought it would be the lift off oversteer you need to watch, all that weight in the back, its not gonna take much to get sideways.
I think it would be easier to control than FR as with RR you have the weight of the engine sat on the back wheels, would be more likely to push the front into understeer esp on gravel rally stage.
ive never driven a FR, 4x4 or RR corsa before tho, so thats just my theory.

Ed it would feel a bit heavy under harsh acceleration, usually creates a bit of stress on the B-Pillars as there will a slight push on it, sounds a bit daft but it's only a tiny amount, but would be worth doing as you could give the corners some hammer on a track day etc.... It would feel like a baby cossie
as for the prat who said you can't weld the front, how's the car shell put together in the first place?
