Hi all, I’m trying to find some sports cats for my late 1992 TT. I’m not having much luck, anyone know where I can purchase some?

Thanks

Dave

How many cells ?

I don’t know bud, what ever won’t trigger o2 sensors upsetting ecu causing engine light etc.

it’s a Dec 1993 uk TT bud

Sorry December 1992

Typo.

Just found out from good old Luke nobody makes them so that answers that…..

Why do you need cats, they’re not needed for emissions test

I think you do for a 92 onwards, to be visible but not necessarily tested for emissions, being the year specified from in the test

Nope.

NO Pre August 1995 300zx requires cats for emissions test.

Emissions standard between 1/8/86 and 1/8/1995 UNLESS LISTED emmission database Annex is 3.5%vol Carbon Monoxide and 0.12% (1200ppm) Hydrocarbons. Aka Not Cat Test.

The Nissan 300ZX is NOT LISTED in the Annex document.

While fitted as standard, the cats are NOT required to pass the above emissions test

And the visual inspection rule only apply to vehicles first used AFTER 1 Sept 2002

Is that for JDM spec cars? Thought UK was different?

That rule was for manufacture of NEW cars not previously in production. Vehicles already in production were given a leeway period. That’s why the have the annex document for vehicles made during that 92-95 period. Basically it was a manufacture law not a DVSA MOT rule

As far as I know this flowchart still stands:

Yep, it does

I recall a discussion with an mot tester with mine, and going through some guides like that, and despite me having that chart, he always got to a different outcome.

Am glad that its definitely not needed, but i think mine always ended up passing anyway.

Maybe he just didn’t like being wrong…

I had the same many moons back, ended up standing next to him as he went through the options on the machine, turned out he didn’t read the options properly and put it down as a post Aug 95 car rather than a pre Aug 95 car…. He wasn’t a fan of being corrected 😂

Very interesting guys love it 👍

Do they ever? I really should have taken my car elsewhere this year.

Every MOT tester I’ve had for the Z hasn’t been a fan of being corrected on this! In the end they used to give up arguing, pass it and take a photo of the chart as a back up in case they had any come back on it. Thankfully from a fellow Z owner near me, have found a tester who knows their stuff so no more stressing about MOT emissions every year!
