emission test is not expensive.
You cannot put an engine in a car that is of of an earlier build, put it on full gas then no worries.

An engine which is of a type offered by the manufacturer as an option for that vehicle may be fitted provided that:-
All other related components including structure, suspension, brakes etc., are equivalent to those fitted to a vehicle of the same model supplied with that engine type as optional original equipment by the manufacturer, and
Acceptable evidence is supplied which certifies that these components are fitted in accordance with factory methods and the vehicle in its modified form is safe and complies with the applicable regulations for that model vehicle.
An engine which is not of the same type as offered by the manufacturer of the vehicle as original, but is similar in power, weight and emission standards to that of the original engine, may be fitted to such a vehicle. If alteration to the vehicle's frame or structure is involved and specially fabricated supports or structures are used an Engineer's Report must be supplied.
Where it is intended to fit an engine which is significantly different from that offered by the manufacturer as original or an option, (e.g. four to six cylinder or six to eight cylinder), then a comprehensive Engineer's report is required on completion of the modification providing evidence that the vehicle in its modified form is safe and meets all the applicable construction and emission regulations for that model. It is recommended that an Engineer is consulted before commencement of this type of modification.
