The ECOTEC engine...in my Astra TS

[droodles]

I'm going to cross my fingers on this one.

Please let the 'TEC' be something related to electronic control of the valves. Just like Honda's VTEC. I know it sounds absurd but cmon. Or should I just get rid of the Astra and go buy something like an Accord Euro right now?

[gmonkey]

Only engine that's semi similar to a vtec is what I got the z18xer. Ecotec is just a name mate not a variant of extra powerband high revving twin cam crazy screaming jap engine like the vtec. Sorry to burst your dream hahah

[gmonkey]

And no the ts didn't get the xer :p

[Shay]

To be more accurate, ECOTEC stands for emissions control optimisation technology, and is the name giving to all GM family 1 and family 2 straight 4 engines. as well as the GMH produced 3.8 V6

i typed a really sarcastic reply to this thread but didn't want to post it incase someone took it seriously :p

the v6's in the cali and vectra's are under the ECOTEC umbrella as well

Correct... Mine has the emotec spastictec ecotec motor

[lithium]

this can't be a serious question :arf:

:buttkick:ECOTEC just kicked in yo!

Soo want that sticker Now ahahha might make it my sig :p

VTEC is just a fake phenomenon created by honda to fool the drivers into thinking there is a difference in power by forcing the car's induction note to change slightly. :p

Nah it actually works. Oh well :( good that I asked. LOL

a gazillion % correct. on the other hand, that mad jolt in the back when the ECOTEC kicks in at 4500RPM!!!!!!















- is because you've hit the limp home cutoff because your cam sensor is shagged


Nah it actually works. Oh well :( good that I asked. LOL

mate i think the answer to your original question is:
yes - you should buy an Accord Euro

[droodles]

Will do when I get the money. I initially had plans to mod the astra but didn't think it'd be worth it. Oh well, it's a reliable car though.

Oh snap..

[gmonkey]

I do love a accord euro but or new shape civic :)

[droodles]

there's not much i can do to it, maybe a CAI and an exhaust system but that's it. it's not a performance type car, at the end of the day it's an astra.

Disagree.. Turbo astra is a performance car!! You can get some killer figures to weight out of them...

I mean ud say a barina is by no means a performance car.. Go check out mr corsas :)

yeah the turbo astra. my astra is your bog standard 1.8L 2002 TS CD.

[gmonkey]

Ohh I c yeh not a performance car without spending massive dollars or ditching everything out of it and making it superlight :)

[InsaneAsylum]

is beating a bunch of faggots from the lights to the speed limit of their clapped out VN with a Unit sticker really that important?

yes... yes it is

[gmonkey]

yes... yes it is
+1 it's the meaning of life in all things motoring

[InsaneAsylum]

so tell me what your usernames are on boostcruising hahah :p

[PrincessPeachey]

even my barina sri can take vx commodores.. so none of this "its an astra" business.

your 1.8L barina weighs a lot less than his 1.8L astra.....

[PrincessPeachey]

your 1.8L barina weighs a lot less than his 1.8L astra.....

redbook actually says that they're around the same weight??? weird. other difference is gearbox, astra prob has the wide ratio. but the point was that the engine has a lot of potential from a few little mods. and also the way you drive the car obviously has an effect..

Yeh but I also beat vx's there pretty darn easy

[PrincessPeachey]

Yeh but I also beat vx's there pretty darn easy

yeahhh but you have a few more ponies than us.

the z18xe is a good engine, wont take much to give it a bit more grunt. :)

[gmonkey]

yeahhh but you have a few more ponies than us.

the z18xe is a good engine, wont take much to give it a bit more grunt. :)

And the z18xer is even better :p

The Misses has the z18xe auto and it is still pretty good still beats vx's ahha

[auzvectra]

i actually have a lot of respect for the z18xe, if u have the x18xe then dont expect to get too much out of it. but the z18xe is the engine of era that the x16xe was back in it's day. it's a brilliant revvy engine, very well balanced, and still uses the small block so reduces weight.

ask some of the guys that have done a lil work to the z18xe how they go :).

or ask me in a few months when Projekt Corsa goes from stage 1 to stage 2 :D.

[EAS51]

Is there actually a thread that says what all these engine types belong too.. I'm getting completely lost with x and z.. I understand the numbers though =).. But to the first poster. i'd go a civic =).

[gmonkey]

Astra f = c series engines
Astra g = x18xe
Z18xe
Z22se
Z20let
Astra h = z18xe
Z18xer
Z22yh
Z20ler
Z20leh

Might have the ler and let back to front

[PrincessPeachey]

haha, i love the xer. sooo much fun even in a wagon! but im still pretty happy with my xe.

the front letter of the engine code relates to the emissions standard at the time. can sorta gives an indication of the age of the engine/car but its not completely accurate. c > x > z > a. none of the engines in aus currently have a but the astra j would have i believe. oh and y is generally for diesels.

[OPC]

either way its all letters to me vtec ecotec zx ze dabajabaza

[gmonkey]

the letter that follows the number is the engines compression level..

so L is low compression cause they are ussually turbo engines
s is 10-11 or so cant remember
y is 10-12
X is higher compresion think it was 12-14

the z22se and the z22yh are pretty much exactly same engine aswell except the yh has direct injection.. but the z18xe and z18xer are completely different

[lithium]

how so? i thought the z18xe and x18xer are identical except for variable cam timing and maybe some work untangling the intake manifold
changing an engine from port injected to DI is a bigger change imo

edit: ah never mind, google answers all. and why am i replying to a thread asking about the TEC in ecotec and racing vn commodores :(

it depends on each individual engine afaik. ie a c16xe has a higher compression ratio than a z18xe but they're in the same range of x.

c16xe = 11:1
z18xe = 10.5:1

The ranges are:
g: <= 8.5:1
l: 8.5:1 < 9.0:1
n: 9.0:1 < 9.5:1
s: 9.5:1 < 10.0:1
x: 10.0:1 < 11.5:1
y: >= 11.5:1.

[sooty]

oh and y is generally for diesels.

Astra G = y20dth
Astra H = z19dth (z19dt for auto's), z17dth, z13dth (only the 1.9 in aus)

[gmonkey]

hate to see how bad the z13dth is :p

[sooty]

hate to see how bad the z13dth is :p
about as poor as the z14xe lol...poor UK blokes get it rough over there.

[gmonkey]

the z14xe was in the astra aswell wasnt it?? i could understand that being in the corsa but not an astra lol

[sooty]

the z14xe was in the astra aswell wasnt it?? i could understand that being in the corsa but not an astra lol

Astra H's in the UK came with a 1.4, i believe it's the z14xe, most of them are the pov pack model called the 'life' or something

[gmonkey]

Breeze?? :p

[PrincessPeachey]

about as poor as the z14xe lol...poor UK blokes get it rough over there.

try a z10xe in a corsa... little 3 banger!

[metry]

i want to drop a 2.0l turbo into a corsa. thatd be lethal

[PrincessPeachey]

its actuallya relatively common conversion in the uk. its insane as.

[metry]

i know same thing goes for the 2.6 v6 in an astra. on youtube i watched a vid of an astra with a 3.2 in it. that was crazy

[droodles]

lol this thread is so derailed. all cars should have valve lift and timing technology, its hektik.

[gmonkey]

But then Holden mechanics would be out of a job

[ChrisMaz]

Everyone knows they aren't HOLDEN mechanics. They're COMMODORE mechanics.

[auzvectra]

Everyone knows they aren't HOLDEN mechanics. They're COMMODORE mechanics.

hahaha

Everyone knows they aren't HOLDEN mechanics. They're COMMODORE aprentice mechanics.

oops fixed :)
