All the same pal, when it comes down to the bare bones. The 20xe may have a bit more than the C20, but nothing noticable. Theyre all worn out now anyway, so the only way to get a really good one is to rebuild it.

[Paul]

no its down to how they've been treated now.

motorway mileage, or driven round town, mileage itself etc etc

in the total vauxhall mag im sure it says the earlier one out of the astra mk2 gtes have 153 and the newer cavaliers calibras and the astra mk3 gsi have 147 even tho the engine codes are the same, how can you tell an early engine to the later one

[gazz]

early 20xe..no oxygen sensor...
later c20xe..

[coombsey]

the engine in my nova has the oxygen sensor but i was told it was an mk2 gte engine?

[gazz]

look at where the engine number is it will say it there..

[coombsey]

where is the engine number??

[loggyboy]

theyre not exact figures but from what ive head on the grape vine early pre CAT xes had just over 150 brake, later catted ones had just under 150, the very late dispacs with 2.8 motronic systems also had a ltitle more, so Decat a late spec one and you should have the most powerful XE (if they are all running in same condition etc etc)

[gazz]

where is the engine number??

on the rite hand side front where the gear box meets block.
almost next to dip stick pipe....

the early ones had a lighter fly wheel (flat type) because they put a heavier one (pot type) on to compensate for the leaning of of the engines and the fittment of the cats as they had to retard the ignition or something for the emisions.

iirc the early ones didnt have the wedge in the throtle housing

general rule of thumb 20xe had dizzy and c20xe was on diss pack but there was some miss matches around the change over as some original 20xe engines can be found on diss pack and vise versa but very uncommon chances are now that if its a miss match and its been out the car its been changed about by the owner rather than beeing one of the original miss match engines

20xe engine also had forged pistons designed by cossworth ect aswell!

there was a fair few variations ect more so on the contanant than in the uk but if you was to sift through all the garbage on the net there is some very informative info out there

but as said now its not so much a case of thats an early engine it must be faster as a better condition newer one may still retain more of its factory fitted ponies that the early one
to be honest i would be more interested in buying a freshly rebuilt one with history than a 60k engine as it will only go eventualy and the chances are now days that 30k out of the 60k will have been hard miles regardless of the tails your told. at least with a rebuilt engine you know its relativly fresh and will only be treated how you treat it and not thrashed by every one of its 40 previous owners

but on the same note these engines have been known to run well into the 200 thousand miles marker without many major problems if treated right and well maintained !

There all getting on a bit, so fit a 2L 16v eco. ;)

my cav gsi was well serviced and it was on 176k,well broken in.. when i sold it,it's still going now over in ireland..it was a tad quick too..

Not quite, only very early non cat models were 20xe (mainly astras mk2s). When new emmision regs came along, a Cat was added and the C was added to the engine code. most c20xes were dizzy models with 2.5 motronic systems. its only very late c20xes that had dispac with the 2.8 motronic system (these have an air temp sensor on the intake pipe before the airflow meter)
