c20 let in an astra coupe?

Nutty_Turbo · 18-01-2008, 14:03

right then guys I might be able to pick up an astra coupe 1.8. and just wondering what your opinion would be about putting my c20 let out of the calibra in it.

so lets hear what you think.

wayne.

sparky33 · 18-01-2008, 14:09

I personally would put an Z20LET in.

Nemesis · 18-01-2008, 14:22

Old engine in a new car... as Sparky sayz the Z20LET would make more sense, especially as they are newer and are just as easy to tune to 300bhp. You could use Coupe Turbo parts as if it were an Coupe Turbo.

sparky33 · 18-01-2008, 14:23

Yes I meant Z, was just going to correct it when you posted..lol

**tathan** · 18-01-2008, 14:23

Did either of you read the part that he's already got the engine?

And an unknown Z'LET against a known C'LET, which is in every way a better engine... Hmmm...

lee866 · 18-01-2008, 14:26

i've seen a c20let in an astra g 3 door and looked very nice and well done but for some reason it doesn't seem right in a coupe. might just be me though.

Yes I did read that, but it would still make sense "not" to use such an old engine in a newish car.

It is also said the Z20LET is a stronger engine, I don't know either way on a personal basis, but it's what I've read over the years.

So it seems it's down to personal choice and opinion, but he could sell the C20 to fund a Z20.

I just think the newer engine would be more easily married up to the Coupe, and would be in keeping with it's range.

**tathan** · 18-01-2008, 14:34

Whoever told you the Z was stronger was wrong. If the C'LET is compression testing ok and he knows it, I'd put that in.

Nemesis · 18-01-2008, 14:35

Tathan - Am I wrong in thinking the Z has coilpack (better than C20LET),counter balanced shafts (better than C20LET), FBW throttle and none of the porous head issues of the older engine?

**tathan** · 18-01-2008, 14:36

Most C's had Coscast.
Coilpack is better.
Balance shafts is the gayest invention ever.
FBW throttle doesn't make any odds.

You'd also be right in thinking the Z has a worse flowing head, weaker bottom end and a load of emissions gayness that the C wouldn't need.

sparky33 · 18-01-2008, 14:38

See, personal opinions..lol

**tathan** · 18-01-2008, 14:41

No personal opinion is where you dislike Sea Bass, the above is technical information.

sparky33 · 18-01-2008, 14:46

But your opinions on the two engines, and which should be used, differ.

**tathan** · 18-01-2008, 14:52

Er, do you understand 'writing'?

known C20LET = win

What you and Nemesis are expressing are clearly differing "opinions", if Vauxhall considered the C20LET to be better than the Z20LET, they would not have introduced the latter.

In your "opinion" the C20LET is better, in Nemesis' "opinion" the Z20LET is better.

The technical specifications clearly differ, giving rise to the different "opinions".

**tathan** · 18-01-2008, 15:52

You're either incredibly naive or your tongue is wedged so firmly up nemesis' arse that he can actually articulate your words with carefully pulsed contractions of his sphincter, either way, you're talking ****e mate.

**RobJenko** · 18-01-2008, 16:09

wayne bang the c20let you already got and are using daily and know its in good order in the coupe. it makes sense to me. why buy an unknown engine when you got a perfectly good lump ready to go in.

***Andy_L*** · 18-01-2008, 16:36

PMSL @ all those who think 'newer' equals better. Numpties

Wayne, sounds like a cracking idea, IIRC correctly the lump is phase 3??

Only queries would be what to do about the coupe drive train?? Have no idea how strong it is?? Are there any issues over emissions?? (Calibras got a cat so shouldn't be but I'm not 100%!)

Next you'll be saying the XEV is a better engine than the XE.

The letters and numbers merely indicate emission levels, compression and engine size NOT that the engine is better.

sparky33 · 18-01-2008, 16:46

I think you will find that there is more than emission control differences between the two engines.

Some of the "physical" differences have already been pointed out above.

And if you read what I said properly, rather than with your biased anti sparky griffin glasses on, you will see I said that I have no personal experience of the two engines, and my comments were based on what I had read, but on the other hand, I would sooner fit a Z20 out of an Astra G/Zaf in an Astra G as it will be easier to marry up. And at least the engine will be from the same family of cars.

The gearbox should be ok, but there's a definite way to find out

If you can prove the engine is out of a specific car or the year of the engine, the coupe will be subject to the emissions regs of the engine, not the car.

Really sounds good, Vauxhall's best 4 pot with Vauxhall's best FWD handler

Well you shouldn't believe all you read then

It's basically the same family2 block you cwd btw, which kinda blows the arse out of your argument. Simply reading something somewhere isn't really a substitute for knowing what you're on about unfortunately, as other members would do well to heed.
