Ok im putting a ST170 engine and box into a what will have been a 1.6. i have all the documents etc and will most likely be having it MOT'd. I have never done this before so not sure of the process. I have to declare it to the insurance of course but what else? My main concern is will it fail on emissions due to the bigger engine? Im no mechanic so be kind

 

emmissions are done on the age of the car i think, so if you put a new engine in it will still go on whatever the emmssions are for the car.

i had a zetec turbo in a 1983 sierra that passed ok (it did have a fully mappable ecu tho that was specifically mapped for the mot lol)

as for who to tell, the insurance of course, and the DVLA via sending off the logbook. they will most likely want you to have an engineers report done on the car witht he new engine in tho. so if you know anyone that works at a garage, you should be fine

 

if the engine isnt any worse than it was in a focus i wouldnt worry, if you doing a decat then maybe but if you leaving the cat on i shouldnt see any issue.
Insurance may want to see a engineers report too you could ask the mot center to check and give you a report shouldn't cost too much.

 

So MOT doesnt work of the amount of carbon emissions in relation to engine size? At first it will just be a standard ST170 setup to clarify

 

When the dvla are notified, the new engine size should automatically come up on the mot I think without you having to declare it. The dvla and vosa are linked..

 

it depends on year of manufacture for emissions, not engine size

 

incorrect for engine swaps.

If you fit an older engine then you get engine age related emissions. BUT the onus is on YOU to prove the engine age through manufacturers letter, engine number date code documents etc.

from a copy of the relevant section of the mot manual i had:

 

if i got it MOT'd before i sorted all my paperwork will i get in the shite?

 

technically the MoT man should refuse to test it. They are trying to change the rules so that the MoT system can take "grassing" reports about cars presented so if you turn up in a cossie converted car, it will be reported to DVLA and your registration revoked until any anomoly is rectified.

could mean a lot of project cars end up IVA'd and on Q plates.

 

when is this supposed to come in? I presume they dont tell the DVLA due to a tax increase?

 

This would be a good topic to make a guide on, i personally have no idea what the process is but im going to have to do it at some point.

 

fuck knows. It was some new mot proposal a couple years back. probably low priority now post election but will come in the end.

the proposed changes to mot were nothing to do with tax, but radically altered/rebuilt and modified vehicles as many modified vehicles have untested mods and potential safety issues that fall outside the scope of regular MoT.

 

When we did ours, a cossie engine into a mk1 xr4x4, i informed the insurance company of the new engine and had to get an mot garage to write a letter on their headed paper to confirm what engine had been fitted. When I sent the logbook back to notify dvla of the change they sent me a letter giving various options to me of providing the details they wanted.
To be honest it wasn't much hassle to sort and only cost Ł10 for the garage to inspect it and write the letter.

 

Damn.. the amount of trouble and cost of parts now days i might just forget my zetec turbo fiesta and just just build a mild zetec s toy.

 

So what happens to the people that don't declare mods? apart from invalid insurance?

 

Not declaring any mods doesn't effect your day to day driving or MOT unless illegal. Decat might land you in bother but after all the years I've spent on car forums it seems no one actually knows the exact law in regards to what having a decat entails

 

I shouldn't think (from a testing point of view) that the tester will care about which engine is fitted.

First it'll get a Basic Emissions Test (BET) to the limits of CO 0.2%, HC 200ppm, Lambda 0.97 to 1.03 on the fast idle and CO 0.3% at idle.

If it fails the BET, it'll get a vehicle specific test, where the tester will attempt to find an EXACT match in his emissions book or database on the emissions computer. It is possible that he may do, if that engine was used in that year of car. If he can't find an exact match, the test will be done to the defaults of CO 0.3%, HC 200ppm, Lambda 0.97 to 1.03 on the fast idle and CO 0.5% at idle.


Grounds for refusal test are:

1. The Motor Vehicles (Tests) Regulations 1981, as amended, list the reasons why a Nominated Tester can refuse to carry out a test. The reasons (amplified where appropriate) are given below:

a. The Registration Certificate (V5C) or other evidence of the date of first use is not produced if the information therein is necessary for the test to be properly carried out. Note: Normally this document will be necessary only if the vehicle has a 'cherished' registration mark or if the registration mark's year letter does not make clear the standard that should be applied - for instance, regarding the seat-belt requirements for D-prefix vehicles. If evidence of the date of first use is produced and it shows that the vehicle was first used abroad, the presenter should be made aware that the vehicle may need a Single Vehicle Approval test (SVA), not an MOT test, before the vehicle can be registered for use in Great Britain and a VT32 Advisory Notice should issued.

b. The vehicle or any part or equipment on the vehicle is so dirty that examination is unreasonably difficult.

c. The vehicle is not fit to be driven when necessary to complete the test because of a lack of fuel, or oil, or for any other reason.

d. The NT considers that insecurity of a load or other items would prevent a proper test being carried out - unless the load is secured or removed.

e. The VTS asks for the test fee to be paid in advance and this is not done.

f. The vehicle emits substantial quantities of avoidable smoke.

g. A proper examination cannot be carried out because of the inability to open any device - e.g. door, tailgate, boot lid, engine cover or fuel cap - designed to be readily opened.

h. The vehicle's condition is such that, in the opinion of the NT, a proper examination would involve a risk of injury to any person or damage to the vehicle or other property. This would cover refusal to test a diesel where the engine's maintenance history or condition was suspect.

i. The vehicle has neither Vehicle Registration Mark nor VIN/Chassis Number/Frame Number by which it can be identified or, that all such identifications are illegible or use letters and numbers not normally used in the English language.

Note: If reason to refuse ‘i’ applies, issue a hand written VT30 containing as many of the vehicle details as possible. A copy of the VT30 should be retained.

2. In addition to the above, an NT must decline to test a vehicle if it is of such size, weight or configuration that it cannot be properly or safely tested on the approved facilities.

3. In the case of classes 1 or 2 a VTS must decline to test any motor bicycle the frame of which is stamped 'not for road use' or words to that effect.

4. When a vehicle presenter requests a ‘refusal to test’ decision in writing, the vehicle details should be registered onto the VTS Device, a VT30 printed detailing the reason for refusing to carry out the test, and the test Abandoned without a fee being charged. Note: Where procedures to be used during Emergency Testing are different from those detailed at 3 and 4 above, they are detailed in Section N.

Having a non original replacement engine is not one of them.

 

Why refuse to test it warren?

I would just mot it like any other car

"test as presented"

As someone has already stated it would get a bet test for emissions, if that failed it would go onto full cat test

 

But that would only happen on vastly different engines or modifications to an engine? people like me just whacking a 2.0 lump from a dif focus wouldnt have bother? same as an RST lump in a bones etc etc?
