Zetec and IVa

[Russ_16v]

Hey guys,

Hope you might be able to help, my build is going to be a fairly long term project, due to the limited anount of time i will have to spend on it, and because of this, iv been researching on here about engine options.

I am liking the (much tried) Zetec route. Its not the most exiting option, but im after reliablilty and a good shove of power which is why im prefering this over a Pinto.

But my question is this:

I have got the impression that a Pinto is a lot easier to get through the emissions on the IVA.

I am planning on going on a Q plate if this makes a difference, but what i would like to do is get the engine i will be keeping in the car, i dont really fancy spending all the time and effort fitting a Pinto, to then have it back in my garage swapping to a Zetec, as due to the time i will be spending it would take me a little while to do so.

So are Zetecs as hard as im thinking to pass the IVA?

I will be going with a pre 95 so no cat or ecu to worry about, so most probably the bike carb route will be taken, as it seems fairly well priced.

Would a bike carb'd Zetec have trouble with an IVA regarding emissions?

Many thanks in advance

it depends what year zetec engine you go for, if its a pre-august '95 engine, then emmissions are more or less a doddle. Post 95 and you will be needing all sorts of stuff like catalytic convertors and stuff.... i think

Yes, i will be going for a pre 95 engine

sorry to ruin your day but its pre 92 not 95. the only way you can get away with a 92-95 engine on pre 92 emissions limits (CO3.5% HC1200ppm) is if you can prove the car that it come out of, didnt come with a cat. for this you will either need evidence in the form of a recognised publication or a letter from ford tech

ok,so if its a 92-95 engine, does that mean im going to have a nightmare with emissions?

[AshG]

your fine as long as you can prove that the car it come out of didnt have a cat.

Hi Ash,
So this has changed since the IVA was introduced then, as the copy I have says if the 'computer' doesn't list your make of car or near equivelent (like MX-5 and eunos roadster) then it had to be taken as non cat unless engine proven to be an August '95 or later. ie a type of engine not introduced before August '95.

In my copy of IVA manual dated 27/03/2009 Page 8 of 13 in section Metered emissions 02B
The flow chart shows:
CAT1
is it a passenger car? = yes
vehicle effective date between 1/8/92 & 31/7/95? = yes
can you find an exact match in the analyser data base or the In-service Emissions book? = NO - because the haynes roadster isn't in the book!
Carry out a NON CAT test CO<=3.5% HC<= 1200ppm

I would call that a non cat test for any haynes roadster with an engine that was pre'95 so long as engine age could be proved - which should be no problem - just contact the engine manufacturer and they should be able to provide a letter confirming date.

HTH BV.

PS this is exactly the same flow chart as the one in my old SVA manual.
