Thanks for the usefull link
I will ask a friend of mine who owns a Bosch service centre (Car Garage) if he can obtain any literature regarding imported fiats and the relevent MOT emmisions tests.
Daywid you mention that swaps is difficult to register in uk, id register the car as a standard 650cc first then eventually carry out a conversion at a later date, can't see it being a problem as theres loads of cars on uk roads with Non standard engines, mk1/2 road legal escorts with 1800/2000cc zetec engines as an example
Unless anyone on here has tried and failed to carry out an engine mod on a 126 id like to hear about it
this is an email i received back after id asked the question about replacing the 650cc engine with an 1108cc engine (dated 14/04/2011)
Thank you for your email to TTS Enquiries about vehicle engine change.
Also once the modification has been made you must satisfy yourself that the vehicle still meets the Road Vehicles (Construction and Use) Regulations. In particular you would need to ensure that the brakes are sufficient to cope with the increased power and that the tyres have the correct load and speed ratings. If it is not classed as a radically altered vehicle then these items will not be tested but you can voluntarily pay for an individual vehicle approval to satisfy yourself that the vehicle is compliant.
Please see directgov link for a radically altered vehicle.
