Thought i would post this in the muppet corner as i feel like a muppet for asking ;)
my 1st xe engine so go easy on me
Whats the difference between the c20xe's i understand they came out of a astra, cav and cab.
I think mine came out of a astra and is a early distrubutor type? Anyone got a picture of one for me to tell them apart from the later one?
Let the fun begin!
P.S I need a loom now :cool: (got ecu motorinc (sp) one lol)
There's 20XE (earlier) and C20XEs, so maybe check the engine code?
What are you trying to distinguish between them?
I've got a dizzy one too, but on the block it's not a C20XE it's just a 20XE :confused:

The earlier ones from the astra gte's have 156bhp. The later ones from the Cavs have 150bhp.
The later ones were introdced sometime in 1991, as an attempt to lower emissions.

Ah never knew that, that why mine done 159 on the rollers. Just bought plugs and filter but asked for c20xe parts...hope they fit?
I've been told the earlier engines have lighter crankshafts, it may explain the extra bit of power,

no lambda sensor on the 20xe iirc

Maybe we need a whole new thread.... but wouldn't that be C20XE - ''C'' as in Catylist?
Any expert on engine codes??
no lambda sensor on the 20xe iirc
Yip that's right on mine:thumb:
The extra 6hp comes from a lack of Cat
Maybe we need a whole new thread.... but wouldn't that be C20XE - ''C'' as in Catylist?
Any expert on engine codes??
the first letter C , E, Z. Is the emisions code iirc

ok guys where can i find the engine code on the engine block i guess somewhere lol?
i need to know as i want to get a loom for it soon and also mine has the 02 sensor
i always thought that the coscast head only came on the early astra 20xe engine. what is the difference between the ignition systems?
Engine code is on the ridge where it meets the gearbox.
why is a serious thread like this in muppet???????

Oh of course, so C would be the highest emmissions band (3%?) and Z being the lowest at 0.5%?
Im sure early 20xe had a lighter crank and flywheel was flat type also, i will be corrected im sure if im wrong lol
Right, 3 different types. Early 20XE's ran dizzies and had no lambda. Next came the C20XE's which ran a lambda but still ran a dizzy. Later C20XE's used a coilpack instead of a dizzy. Thats the main ways do differentiate at a glance, there are other differences.
Cosscast heads tended to be used on the Astra 2 GTe's on the 20XE's but some found their way onto Astra 3's and a few cavs.
Engine code is on the front face of the block near the gearbox. It will probably be caked in crud and nigh on impossible to read though.
And there is a guide on engine codes in the Articles section. It was one of the first ones we put in so itll be near the back
Edit: http://www.pngclub.com/forum/showthread.php?t=93409
were all 20xe's c20xe' etc as reliable as each other or was one engine more robust?
Just the pourus head problem
The 'porous' problem with GM heads is not actually a pourosity problem, the heads actually crack, and the main reason for this was the manufacturers got the torque settings for the headbolts wrong, so early GM headed engines will have spent a certain amount of their life under stress.
A Cosscast head will not give you any more power, despite the name, and im my experience, if you a tuning an engine, a GM head will actually flow better if you mod it :)

Right i belive mine is a early c20xe then it has the dizzy and also a lambda sensor with the coscast head :)
Just to keep it all in one thread what loom do i need a astra one or will any c20xe loom do the job? (early loom that is)
puss puss, i have a loom and ecu i dont need for an XE.
and what does the cambelt set up look like. as they changed early to late
ill try and get some pics :)

ok that is an early type ^ mine also lol, note the pulley arrangement
Yeah, some had square tooth belts, some had round tooth blah blah. Vauxhall were as bad as Ford for mixing and matching stuff.
As for looms, so long as you have one that will run a lambda and a dizzy, it will work with yours.
can this get moved to mech please??? its quite a good engine thread.
edit, thankyou powers that be

Mine is the same setup, just went and had a look with a 02 sensor in the exhaust
and the dizzy on the exhaust cam? i think thats what it is lol
pm me price for the loom i got the ecu dunno if i need your one as well or what lol cheers mate :thumb:

Take the ECU as well unless you are sure you have the correct one for the engine.

Sure just contact a mod i only put it in here because i felt like a muppet for asking this question in the 1st place :thumb:

Ok thanks for the loom information i will have to hunt one down now :tard:
and vauxhall as bad as FORD! :mad::cry::mad: wash your mouth out with soap sir!

am sure its the right one doesnt the ecu need "coding" to the engine as such? am pretty new to this stuff :thumb:

Its already moved ;)
Ford Escort MK5's have 5 different types of alternator, and theres no way to tell which ones in there until you remove it so they were blatantly rummaging around in the parts bin towards the end of their manufacture :roll:

no coding needed, but you will need the correct ecu to run a lambda with dizzy, as opposed to a coilpack
Well so far in this thread I know that I have an early 20 xe with all the right bits attached and loom and brain my only question is how do I spot a coscast head? The engine is fully build with both manifolds attached and has been sitting that way for the last 7 years in my workshop!
coscast head,
its stamped on the under side of the right front,
there is a different end casting.
and the main one looking front on, the heat shield tabs are not circles, they merge into the head
Look on the side of the head on the gearbox side. If there is a hole blocked up with a core plug, its a GM. if there is no hole at all, its coscast.
Coscast is also stamped on the rim, but again, youll never find it, its probably caked in poo lol

Cheers guys, early XE with GM head, it has the core plug:thumb:

im sure mine is from a late cav as its coil pack,info from the engine code said its only 138bhp:(

138bhp is the Ecotec is it not?

im not sure....can anyone confirm if the 138bhp is an ecotec?my engine code starts with c20xe ...
isnt an ecowreck a z20xe? might be wrong
and whats the top look like......has it got a straight black plug cover or an L shaped plug cover

its an L shaped plug cover mate:thumb:
Ecotec is C20XEV :)
138 bhp will be the output with the CAT. if its now in your nova without a CAT, it will make 150 BUT its probably tired and only making 130 odd anyway lol

ok thanks mate,i was certain it wasnt an ecotec but i was still a bit worried there lol

Ecotec is X20XEV.
Ecotec is X20XEV.
LOL, that was an honest typo, but less convincing than if i put S20XEV. I like the fact C, X and Z are all next to each other. Any uber lazyness by the man who made up the emmission codes gen? lol
