Title: Signum
Post by: EMD on 04 December 2015, 16:33:05
Vauxhall Signum 2.0i 16v turbo manual , any good  :-\ I believe mr opti has the full fat 2.whatever it is but this being the 2.0 not sure . Didnt realise they made a 2.0 petrol turbo  :-\

My other deal fell through after no contact from the seller after an initial agreement  :(

Goes alright, but thirsty due to being only a five speed close ratio box... 75 is about 3500 RPM iirc :o

Signum shape is growing on me tbh.. Sure Lord Opti has the 2.8 V6 Turbo Elite variant around a 2007 plate. They are good value for money now an all.

Yep.....it's a bit of a wolf in sheep's clothing. 250 BHP and 258lb ft of torque at 1800 RPM. With a remap 300 BHP and 400 pounds of torque....all through the front wheels though. :-\

Nobody gives it a second glance .....which I like. :y

Out of curiosity what are the recommended intervals mileage/years to change the cam belt on the 2.8 engine, Same as the Omega?  Presumably a cam-belt fitted to these?

Have also been wondering about the reliability of the Turbo, Any known issues or an expected life span.. Would have thought a new Turbo wouldn't be cheap. :-\

Even the later 2.8 V6 are in the (good) Omega 3.2 price range now  :y

This one LINK (http://www.autotrader.co.uk/classified/advert/201511218883239?atmobcid=soc4) for example £1,490 on an '06' plate

Inside is pure Vectra so dull as ditchwater. The exterior looks are slowly growing on me although the Signum does appear to have a 'big arse' when viewed from behind. :y

With a remap 300 BHP and 400 pounds of torque....all through the front wheels though. :-\

Nobody gives it a second glance .....which I like. :y

This - mine has been, probably only around the 280bhp mark but its got a shed load of torque over standard

I will acknowledge it is a bit of a nightmare in the wet for the TLGP even with an auto box  ;D

They don't all cost £500 a year RFL, mine is an 06 plate and costs the same as my 3.2 Omega, it doesn't drink silly amounts of fuel, in nearly 9k miles in the last 6 months its averaging 24.2mpg, bearing in mind mine is a daily driver and I drive in and out of London in a lot of stop start traffic, that to me is more than acceptable, be a girl and that could easily be nearer 27mpg.

Its very similar to sit in and drive to the Omega, but considerably quicker than the 3.2.

I previously had a 3.2 Signum and that was quicker than the Omega, same fuel economy but for the cost I would not bother just get the 2.8.

Same goes for the 2ltr turbo, 180ish bhp as standard is a little weedy for a car that weighs about 1600kg - depending on spec - hence why quite thirsty.

The 2.8 turbos are cheap because of the scare stories over Insignia and Vectra VXR 'chain stretch'. Its quite rare, and there is no correlation between age, millage, tuned or not and the problems - worse case scenario a set of chains and oil pump can be done for less than £1100 independently up to £2k from a Vauxhall dealer

Does put quite a smile on my face driving, it will give 330/ 335 BMWs, ST Focus, R32 Golfs a run for their money, and when de badged most people don't have a clue what it is

According to the trip computer, which may or may not be accurate, the readout shows 27.3 MPG over the last 7000 miles. There are quite a few longer journeys included in this figure though.

I'm currently thinking of a 'tuning box' as opposed to a remap. This can be removed when the car is sold and used on another car.

Snake oil?

Bluefin by Superchips.

Removable when you want, handset is also a basic code reader, you download a copy of your map currently on the car, send it to them, they then send you the new one back.

After over 30k miles its been reliable, but you may need new/ re gapped spark plugs and it will highlight coil pack deficiencies

Well worth the £300 they occasionally discount them out for including a K&N filter - Ebay or Demon Tweeks is your best place to look

Yep......four maps none of which made any difference whatsoever.....apart from sending the car go into 'limp mode'. :-\

Very odd, mine has been fine and noticeably different, it could be coil packs and plug gaps causing the issues, happens a lot when these are tuned and GM did change the plug gaps on later engines.

Another option is EDS which is quite well respected.

Also JZW do a lot for the SAAB version and are moving into the Vectra, but its still being developed, a Vectra VXR with a JZW was no match for my Signum, which was quite funny, but the Vectra did have a lot of gear in the boot which will have blunted the performance a bit

Dave

The 2.8 V6 Turbo Signum uses the same gearbox as the VXR (and other spec) Vectra - AF or F40 6 speed - which iirc is pretty much bullet proof, its the M32 that's a bucket of wank and not sure if it was used on the Vectra C

Older V6 and diesel Vectra/ Signum used the AF33 5 speed that had water/oil in the heat exchanger killing the box issues, but that's the only major gearbox issues I've heard about (and had happen)
Title: Re: Signum
Post by: Marks DTM Calib on 06 January 2016, 08:58:24
Yep, nothing at all wrong with the auto boxes, it was the early ones that's suffered the oil cooler failures resulting in coolant in the box which created the false impression.
Title: Re: Signum
Post by: Field Marshal Dr. Opti on 06 January 2016, 11:12:29
Six speed auto on mine is fine. Nothing nasty to report.

Even when remapped with an extra 80 lb ft of torque the auto box seems to cope without any problems.......although I have heard of clutch slip with the manual box.

Think you might mean the box fitted to the Astra H... Doesn't like being ragged, especially with the higher output diesels... istr that the Vectra box is physically bigger and won't fit in the Astra chassis, hence the lighter weight box :-\
