Engine

Alternative cubic capacities of the same basic engine and alternative original equipment engines are not considered to be a substantial change.

If the number of cylinders in an engine is different from the original it’s likely to be, but not necessarily, the case that the current engine is not alternative original equipment.....

 

Acceptable changes

It does not count as a ‘substantial change’ if:

• changes are made to preserve a vehicle because the original type parts are no longer reasonably available
• they are changes of a type which can be demonstrated to have been made when vehicles of the type were in production or within 10 years of the end of production
• axles and running gear have been changed to improve efficiency, safety or environmental performance"

I have a 1980 1275GT with a later 1400 Minisport engine in it.  I decided it was just an alternative cc of the same basic engine (which it is!) and therefore claimed the exemption without issue.  I don't think putting a newer version of the same basic engine is too contentious!?

It would be a 1380 so I’d probably just assume it would be a legit replacement

As it is classified Historic there is of course no need for an MOT test, but if you submit the vehicle for an MOT test your possition as regards emmission testing is covered by section 8.2.1.2 of the MOT guidelines.

Section 8.2.1.2 says that vehicles used before 1st September 2002 fitted with a different engine must be tested to the requirements of whichever is older.

As an example a 1995 vehicle fitted with a 1991 engine (of whatever make), must be tested to 1991 standards for emmission purposes.

The onus is on the vehicle presenter to prove engine age
