How Do I Know Which Engine I Have?

[sushisushi 0]

How do I know whether I have a XU9JA - D6B with 130bhp or XU9JA/Z - DKZ with 122bhp

 

Mine is a 1.9 gti H reg 1990.

front of the engine left hand side down toward the bottom of the engine mount there should be a little plate there that tells you

most likely to be the 128 bhp XU9JA.

Hope so, what was the other, least powerful engine for? Selected markets?

[welshpug 1,627]

cat equipped, mostly found in later cars.

[sushisushi 0]

ah, what year did cat start?

Pritty sure it was 1992 half way through the year cats came in there abouts

looks like im a safe pre cat bet.

[welshpug 1,627]

not really, quite a few were built earlier.

[Zacky-94 7 2 Cars]

I missed having one by a month or so the Mot tester said

 

mines a J reg 1992 so pritty sure your safe

mid K was the point where they became compulsory I think so a J plate car falls before this time and does not need to be equipped with one, that is how i understand the rulings

Was a option from 1990, It's a better engine to have anyway not that many people will agree with that

Aug '92 it became compulsory, but that's build date not registration, I have an Aug '92 reg'd non-Cat car.

Out of interest Miles why do you think its the better engine. My dad has it in his K reg Cti and I just don't think it cuts it. Lovely for just cruising in 5th but it lacks the poke in my view.

[welshpug 1,627]

cti was a different engine, was a 105 bhp low comp engine in most!

 

122 bhp engine has Motronic which controls spark as well as fuel, has a lambda of course due to the cat needing quite strict control of the emissions for it to work efficiently.

[Weser 30]

Ahh that would be why then. Not driven the 122 bhp version.

[Miles 331 1 Cars]

Better ECU (Motronic) basically and the power difference is minimal when you think not that many 1.9's made book power so you would be looking 3 or 4 bhp difference between them

[welshpug 1,627]

indeed, my Jetronic only made 122 bhp till I swapped it for Motronic
