Title: Difference between 4 pot and v6 Engines
Post by: JamesV6CDX on 03 March 2007, 02:13:21
I drove a friends decent 3.0 Elite tonight...the one I rebuilt much of the top end on last year.. it opened my eyes a bit..

Having driven nothing but V6 Omega's for the last couple of years, I must say that going back to a 2.0 16v, having had it for a short period, I am extremely disappointed  >:(

Yes, the 4 Pots are not bad engines.... in Vectra's. Unfortunately in the Omega, they're not fully up to the job. I wanted to overtake something this morning, I could have easily done it in the V6.. but I didn't dare risk it in the 2.0. . it just didn't have the balls...

The 2.0 is completely un-refined, and rough, nowhere near the level of smoothness of a decent V6. The only advantage is that they are easier to work on due to more space.. but the trade-off is that they're not as reliable or durable as the V6.

Going up the road in the 2.0 this morning, first few miles from cold, you genuinely would have thought it was a diesel!!!

Insurance is no better on the 2.0 than the 2.5, and not much difference between the 3.0

Economy... don't get me started. YES the 2.0 is great on a run, returning 37mpg plus... but normal driving, it's no different, if not worse.. than the V6.

Wait until youve converted it to lpg   :-X

James, I am a little alarmed by what the sound of your engine when cold...

The 2.0 is quite durable but not an engine I would choose in an Omega. Reliability is similar I would say.

But ultimately you know where your heart lies.... now all you have to do is convince the missus a Monaro is a good and sensible choice!  ;)

Well I have gone from 2.0 to 3.0 back to 2.0 (and back again when selling 2.0) and the 2.0 was not that bad, good on a run, but hard work when fully laden.

If you want my honest opinion do up the 2.0 with every available gadget and run it for a year while you sort a project Elite or similar.

You will save a fortune on gas.

Just avoid driving V6s in the mean time.

A working well equipped LPG 2.0 will be worth a decent amount. People always gravitate to the 2.0 when they are short of cash, they see a big comfy cheap car with a reasonable sized engine which is not scarey and they buy it.

I would even say a well equipped older 2.0 is worth more on the S/H market than a V6 to the right buyers (the scared buyers).

Then you can talke your time with say an Elite and fully sort it, gas it, detail it, we need an article on this for the GLS bonnet!!!!

I agree completely.  In particular, the 2.5/2.6 is a great compromise on performance/economy.  If I was LPG'ing, I wouldn't settle for less than 3.0/3.2...

Whilst I have no intention of delaying the gas conversion... I really must sort out the cam followers before doing anything else.. they're getting worse, quickly...

Its horses for courses......and clearly yours is not running right at the moment....

I find them quite adequate and durable....post 97 engines are better and smoother thanks to the addition of the balance shafts......

You do need to rev them...

And its that that imho means they are not drastically more economical around town. The 2.5 has the effortless power to gently accelerate, but the 2.0 needs a bit too much encouragement (hence petrol)

James, remember when we did my cambelt, I started it when you finished..... my 4 pot had not had a run in over a week. Now its its new belt and tensioned right it seams better than ever. Now the belt is right it no longer sounds like a diesel in the morning.

However they do lack the power... something the 24v Senator does not. (Compared to the 2.2)

Booting it in the Senator is great fun, too temping most of the time, being young I and having a Saxo behind me being an arsey git i have to show them up.

However i still prefer the Omega to drive, even though it lacks in grunt. I have done plenty of overtaking in my 2.2 and it does it fine, as Mark says you just have to rev them good  ;) -

Benefit of having a manual, keep the revs high  ;)

I agree the v6 will have more grunt than the 4 pot, but I have owned my 2.2 for nearly 2 years now, have never had a lack of power with it, i live in hampshire and twice a month it goes to surrey up the A3m in cruise control to keep it at the 70 limit, also goes down to cornwall a few times in a year, also never found it to lack power to keep to the max speed limits. But and a big but the run to work if I use the M27 in the morning goes from stand still to 20 mph for the first few miles until I clear the portsmouth section then with luck you might reach 50 mph if lucky, the volume of traffic down here is terrible these days, so I made sure I plugged for an auto for all the stop start driving and the comfort of the omega. So as you can read during the week a milk float has enough power to get around our area LOL. So really the power of the 2.2 omega is enough for the hampshire area, all I can say it must be nice for you who can open up your cars on these quite roads. Also we have an influx of safety cameras, always brings a smile to my face as sitting in a jam seeing the camera.

Guys,
power is something subjective. It depends to what you are used to and how you drive. I'm sure that you can get a 2lt going pretty fast if you know how to drive it but again if you are used to drive something more powerull then a 2lt omega might seem gutless. If you take a 2lt omega to Greece for example where cubic capacity is taxed and everyone is used to audi A4 1.6 and BMW 316s the omega 2lt  will seem like a fllying machine.
My personal view is that once you have had 6 cylinders there is no looking back. I would never buy a 4pot engined car now.

My 4 pot will match any car on the road in the traffic jams around here.....

The only place mine struggles is on motorways when its conjested and then starts moving again quickly.....sometimes i have to use kickdown and full throttle just to try and keep up with the accelerating traffic  :(

But if i was on petrol....that may not be the case  :-/

My MV6 is currently like that. I suspect a tankful of Asda has made it flat.  Once I'm nearly empty, it'll get some high octane and a damn good thrashing, hopefully that will cure.

I normally get between 320-350 miles per tank on Tesco 97, but the last 2 fillups has dropped to 270 - 300, + poor performance.

Yesterday I filled up with BP Ultimate.. and WOW, the car sings again.

Can't wait to see if there is an improvement in mileage.

I usually get 10% extra with BP Ultimate.  Currently using Shell Optimax as it's cheaper and car purrs.  Mpg up and cleared 400 miles with £50 - combined cycle.

Your MV6 should not be struggling to keep up.....a 2.2 on lpg maybe....but never a MV6  :o

It feels like its towing a burger van, but I did check the mirror, and no mobile bedsit following....

Have to see what the next tankload does.  btw, it was filled at Asda in Wheatley, so further west than the current 'problem'

I drive an old 2lt 16v and it goes, ok went well  :-/, it does need plenty of revs but as an ex-biker, thats part of the fun!  Only drawback is fuel consumption but I get anything between 28 to 38 depending on if I'm commuting from here to Swindon or if I'm on a longer trip, either way, I always try to enjoy the car.  :)

Agreed the 2.0 can go well.. we just drove from Oxford to Cardiff and I got told to slow down several times ;)

But... it does need high revs.. which increases consumption.. whereas the V6 can produce the same performance at much lower revs.. hence making it as broad as long on MPG...
