Right i currently own a 1988 mk1 1.3sr with a straight thru exhaust, i understand that because it is before 1992 a cat is not needed, and wasnt used on cars older than 1992.
But..........if i were to buy a J reg nova which is 1992 i think, therefore had a cat, you wouldnt pass an mot with out one..
Wat if when i put the GTE engine in(being before 1992), with my current straight thru exhaust system, will it pass an mot?
L
If you put a 1993 engine into your 1988 car, it would pass without a CAT.
So yeah, a gte engine will pass.
Only August '92 onwards should have a cat fitted.
Most J-reg's can pass without, as most were registered before aug 1992.
But, if you fitted a 1988 engine, into a 1993 shell, it would also pass without a CAT.
Confused? Lol

No thats fine, u see i might not be putting the GTE engine in my current 88 sr, im lookin at buyin a J reg nova in cuple months, and putting the GTE engine in that, but gettin a straight thru exhaust!
Therefore it would be a J reg with Older GTE engine.
Wat if i put the gsi engine in then with a straight thru, wud it pass then ?
Sorry bout questions, jus makin sure!

If the engine is a e16se it'll pass.

Ah ok thanks guys! :thumb: Been a big help, and saves me havin to keep thinking about it lol!
Just cant wait to get it done!

yeah but,as its not aftera k plate, you should be able to get away with it..
as its 93 (k plate) on wards that have to have a cat.
Depends on the tester sometimes too, my old J-reg car had a CAT test.
If you put a c16se into your J-reg(pre cat) nova, it would/should pass a no cat test.
a j reg car should never have a cat test,

Bang on, whatever is older engine or shell, the age of the older part is what the test is centred on. Its on Department of transport website somewhere

Have a look on there, Left hand coloum, about 2 boxes down
http://www.motuk.co.uk/manual_730.htm
It does go on what is older.
A 1994 engine in a 1988 car wont need a cat.
A 1988 engine in a 1994 car wont need a cat either.
Whichever is older.

sorry dude thats wrong,its all on what year the engine is,if its a 93+ engine it needs a cat,no matter what shell its in,my mates cav is a 91,have a 94 engine in it,and has to have a cat test,his nova is a 93 k plte, with a 90gte engine in it and does not need the test,
Nar its not, im right :p
Only 1995 onwards cars with 1995 engines 100% need a cat.

"
Test according to which is older, engine or vehicle.
e.g. A 1995 car fitted with a 1991 engine (of whatever make), test to 1991 standards for emission purposes."
no, as we're talking about on msn,the cat test is tested on the engines age for the emission rules,the shell means nothing,if the engine is register as later 93, it has to havea cat no matter what shell its in,
Hrm, what Benn said on msn does make sense.
Perhaps it was just the old system that was car and engine.
I'll ask when mine goes for mot in 2week. Lol

Could make MOTing my nova interesting if thats the case, its a 94 engine and im not putting a Cat on it, will have to see what happens. Im going to have a printout of the MOT page with me tho so will see how it goes
if its a 94,you'll need a cat to pass the test,anless you try and talk then in to believein its an earlyer engine...

Right the Mot tester is here, 92 K plate car with same year engine is subject to a cat emmissions test.
Upto 92 J only requires a two gas test co 3.5%max and hc 1200ppm max
Okay that the simple bit.
Examples; 88 nova fitted with c20xe from cav 93, requires a 2 gas test as the car is older.
94 cav fitted with a c20xe from a 91 astra comes under a 2 gas test, BUT only if the own can prove the age of the engine ie copy of the old logbook which includes the engine number which can be match to that fitted to the car.
In short the vehicle is test on which ever is older, but only if proof of a is shown. So if the car is fitted with an older engine you need proof, but newer engine fitted to a early car need not worry as date of reg will come up on computer or by the reg plate. SIMPLE.

So going by what your saying my J reg Nova (first reg 1st aug 1991) fitted with my V6 from cav will be ok for not needing a cat, i have both logbooks here and the cav was first registered 3rd feb 93 so its not 94.
Thanks

As i thought.
So my 1992(k reg) nova wont need a cat now as it has a 1990 engine in it.
And a 1993 engine would NOT need a cat if it was in a 1990 car?
What is classed as proof for the age of the engine? A engine code without a C in front of it?
Technically no car requires a CAT :D
I would assume engine code wouldn't be suitable as proof of age of engine... no doubt they'd need a specific date

So yeah the 92 doesnt need a cat
1993 engine in the 1990 car doesnt need one.
Will be the engine number. So the old log book of the car the engine came out of. If the tester knows his eggs, like me:D He/She should know.
