Astra is more or less 1/2 tonne lighter.

27th Feb 2006, 16:15

As I said earlier, 152mph is just a claim by Vauxhall. Autocar tested it in 2002 using proper timing gear and only managed 137mph flat out on a runway (I still have the magazine). Visit www.vxon.co.uk and raise it on there if you're still not convinced ;-)

The SRi turbo is quick, not had mine past 135mph as it gets a bit scary. Rolling I have been on par with Subaru's, but get trashed on the twisties. Managed a 15.2 1/4 mile with wheel spin and bouncing off the limiter in first, sub 15 possible with a decent getaway.

Have raced many cars, don't think it quite has the pace to beat M3's, Porsches etc on performance. But most lack guts, so are beaten that way.

The Astra is a fast car, but it was never meant to be as quick as an Impreza. The 0-60 and 100 are considerably lower for both GSI and SRI. And the BMW M3 would blow your doors off.

I have one of the 500 SRI 190's. As many above have mentioned this is a cracking car with loads of potential.

I can categorically garantee that my car is standard and I have had it up to 150mph - on the M69 whilst racing a Cupra R (OK it was a long run, but its still did it!)

The published 0-60 time is rubbish too, I've have comfortably done it in 6.6 seconds - and that is with the traction control still turned on.

C'mon buddy, the M3 is in a different league!

4th Feb 2007, 07:43

Just to agree with the above comment on the sri turbo 190. I own a red 2003 (jan) model and it is a great car and very fast for the hot hatch league. You can't really start comparing it to an M3 as it is a different price range. Saying that though, the M3 isn't fifteen grand better in my opinion. My car will do 0-60 in just under seven seconds and it has no modifications whatsoever. I doubt the M3 is that much quicker? You do need to compare similar priced motors really to be honest.

I also have an Astra SRi Turbo (02) in red. I have had the odd play in it with my friend in his E36 M3 Evo & in standard guise the E36 has a good edge on the SRi T. I have now had the car mapped to 286bhp & 331lb ft torque!

Traction is obviously an issue with this amount of torque from pull away in a front wheel drive, even with traction control turned off, but once rolling it is awesome & very capable of nailing an E36 M3.

12th Feb 2007, 06:15

I have 320bhp/350ft/lb and can pull ahead of m3's and rs4's to mine and there surprise, have got 285bhp per tonne though.

12th Feb 2007, 10:34

That's some great power! What software are you running & have you had any internal work done?

12th Feb 2007, 11:24

Yes 320 BHP is a lot to have in an astra, how much do they weigh? somewhere in the region of 1250 KG id imagine. BMW's and RS4's are around 1600 KG arnt they? You could get that much power easy from the astra with the 2.0 turbo set up if you spent the money, but did uprate the drive shafts and clutch too because that's about 130 BHP over standard, they must take a bit of a beating.

I have a Astra 190 turbo 2002, but dont know how to switch off the traction control. can you advise me? thanks.

9th Apr 2007, 01:45

According to www.whatcar.com, the 2003 2.0 GSi 197 BHP does 0-60 in 7 seconds flat. I can't see the SRi being any faster than that.

There is no way you could keep up with an M3. They do it in 5.2. I own the new VXR stage 1 and 2 remap. A few weeks ago, as I was pulling away at the lights from a Golf R32, an M3 went past both of us.

Aup mate for the T/C switch I had the same problem you have to order the switch from vauxhall wire and switch comes all together, all for bout £15.

4th May 2007, 13:56

Hey, I've recently purchased a Astra 190 turbo. I was told that it already has a dump valve on it. where exactly could it be located. thanks.

8th May 2007, 05:22

It'll be obvious if you have one fitted, just listen for the 'whoosh' when you change gear.

16th May 2007, 07:19

Hi could anyone please tell me the 0-60 times on the Vauxhall Astra MK4 2.0 sri and the 2.2i sri thanks.

17th May 2007, 08:57

Mk4 Astra SRi 2.0 16v: 8.4 seconds (according to Autocar)

Mk4 Astra SRi 2.2 16v: 8 seconds.

29th May 2007, 15:10

All standard turbo cars have a recirculating dump valve which returns the excess boost on gear changes back into the system as opposed to atmosphere! You can block some up when fitting an atmospheric dv, but the SRi T dv is controlled by the ecu & it is not advised to blank it off! However you can restrict it so it does not open as much.

27th Jun 2007, 23:18

I have a 1.8 sri and it's not fast enough! so... it is now on Autotrader, and soon as I get the cash for it, I'm getting 2.0 turbo. Sweet.

Oh, and I want a dump valve so it sounds the part. Any suggestions??

29th Jun 2007, 06:34

'Oh, and I want a dump valve so it sounds the part. Any suggestions??'

Yes, don't get a dump valve, it makes you look like a ****, unless its on an evo or scooby.

25th Oct 2007, 08:17

Nothing wrong with getting a Pipercross. I had one on my VTR. Didn't make it go any faster and didn't seem to help fuel consumption. Just made noise. Other filters will probably add power and help fuel consumption.

14th Dec 2007, 16:43

Keep up with an M3? I've just been totally creamed by a 328se, 330ci, and an m3. They were racing along the 303 recording themselves or something. A driving error on my part you might say, but it's a straight road; all you do is get the turbo in boost and floor it and I died on my pass. If that ends up on youtube I'm going to kill myself. (I just like to add that I too would have said I was as fast as said cars until this evening.)

4th Feb 2008, 13:52

Incompetant driver.

5th Feb 2008, 06:12

If they were racing, then theres a fair chance they were all modified.

People always comment on here about beating/losing to this and that, but most of the time they don't know if they're racing against a highly modified car or one with quarter of a tonne of bricks in the boot.

5th Feb 2008, 07:34

No, just refusing to drive like a bell-end on the public road. There is a difference.

That's what trackdays are for.

1st Apr 2008, 11:41

Don't get the SRi turbo as it's the slowest of the lot.

17th Apr 2008, 18:33

Ignore the comment above..

I've owned a 53 plate Astra GSI in Arden Blue and its the best car I've ever had.. I've owned a Cupra R and a Golf GTI... which are nothing compared to this Astra.. Boy does it go.. It's all about the way you drive it... I mean mine is running standard apart from a full exhaust system. But on the road there's a large list of cars I have comfortably beaten in a straight line... e36 M3 alpine, Clio 197's & 182's, Civic Type R (new and old), Leon Cupra R, Volvo T5 and D5, 330ci e46 BMW.. Up 2 140 mph... oh yeah.. had 150 outta mine without a sweat... STANDARD..

Go for the GSI... holds its value better than the SRI-T... even though I'm getting an SRI-T as well as my GSI..

24th Oct 2012, 17:07

The SRi T, the GSi and the coupe all have the same power, and exactly the same engine. They called the SRi the 190 for insurance reasons, hence why it's 2 groups lower than the GSi/Coupe.

15th Aug 2014, 22:13

I've had my Astra SRi Turbo now for 3 years, never missed a beat, running at 362 BHP; it actually scares me when I put my foot down sometimes. Front wheel drive cars should never have this much power in them.

13th Apr 2015, 11:15

If you're running 362 BHP, that means there's not a single OEM part inside the engine. At this stage the poor cheap Z20let internals just break apart.

16th Apr 2015, 08:44

The SRi is not slow.
