not understeer or oversteer as such, thats gonna depend on the setup and spec, just the weight is in the wrong place for it to be nice and predictable, it will be a snappy POS to drive, there no getting around that.

if you dont completely seal off the engine from passenger compartment you will hate to drive it due to the noise and smell.

the rear compartment will get constantly covered in shite due to it now being open to the elements.

do your cooling setup VERY carefully as its really easy to either get it not working well, or if the rads at the front, massive head gasket blowing airlocks in the system.
