I started digging the official online Confederation information but would like to ask if anyone here have any experience or know the process on MFKing a car with a heavy modification: ditching the original engine and putting something more powerful and dependable.
Specifically, I am considering either buying an original Lotus Elise and sending it to a specialist in the UK to have a Honda K Series engine transplanted, OR my preferred choice that is instead to import a car with the transplant already in place.
1 - If I import the car with a swapped engine, how difficult would it be to get a MFK for it? What are the costs involved?
2 - If instead I buy a 12-year old, CH-registered Elise with a fresh MFK, and then have it modified in the UK, how long can I drive it in CH before the next MFK?
You can get away with boring or stroking an engine that was original to that car, or even swapping Webers for SUs.
But a power increase with an engine that that car was never built with, particularly as it says HONDA on the engine and LOTUS on the body? Nevah! (Even an 18 yo inspector who thinks cars without Bluetooth are antiques would notice it.)
I'd say that such modification should be reported and that it would be fraud not to mention such and thus the amount of days he would be legally allowed to drive such care here would be zero. this regardless of getting in an accident and than find out that the car never was road legal.
Remove old engine, put new engine in the car, trailer the car to MFK.
Show the car and documentations that the car with the new engine meets all noise, emission requirements which are relevant for the car, and the whole setup is structurally safe according the relevant standards.
I do. The point is that when the inspector points to the Toyota/Rover engine and asks "Is that right?" you can point to a document which says "Yes". He will then leave you alone.
If you can't prove that the car was originally supplied with that engine then even if he likes the idea, then you end up having to prove that the suspension/brakes/trans/diff/steering are up to the weight and output of the engine. (If you look at aSwissInTheUS's link, the details are based on how much you've increased the output by.)
And they won't take a youtube video of a guy from Scunthorpe who ran the same combination as "proof".
It's worth asking. They're not monsters (most are gearheads). The answer will probably be either a straight out "No" or a more detailed "Possible, but prohibitively expensive."
