VT vs. VP

[tyrefryer]

Heres the story, i used to drive a VT which was my first car and i was used to it, then i went to a VR ute then a VP commodore and now iv bought another VT. Problem is the VT's just dont feel and drive the same. my VP is on gas and it still feels like it goes a lot harder than the VT. if i push it, it kicks and goes but the VT just isnt as responsive and has a delay and a slow increase when u push it. iv heard other ppl mention this aswell.

What i wanted to know was is there any small things i can do to make the VT a bit more responsive cos im worried about selling my VP then driving a granny car when i could just keep my less valued VP. Also does anyone know why VT onwards just arent the same as VS down. i thort it might have been the ecotec but VS's go just as hard as VN VP's, its only until VT.

BTW im talking V6 auto's

because they have the same motor and about 300kg more. thats what kills the power the only way to fix a vt not havin much power is to put an ls1 in it even then they are nothing special standard.

Hey mate,

Problem with VT onwards is they are HEAVY cars....
From memory a standard VT is about ~1550kg give or take, meanwhile the VS is only 1400kg. So you add 150KG (Or roughly 10% of the cars weight) and your going to increase 0-100 time by 10%....

Also the VTs are tuned more towards smoothness etc...

If you want to increase the responsiveness of the VT, try things like CAI, K&N, Memcal Retune, Stage2 Shiftkit, better spark plugs, exhaust, bored out throttle body etc. Depends how much you want to spend.

Also depends on the VT your looking at? What was it last serviced, any error codes, how many kms, what fuel you using etc etc etc

i wouldnt bother doing all that to a v6, u can get an ls1 for 2k and all that tuning exhaust cai would cost way over that.

Spoken like a true V8 snob..




I drive my old VP V6 still, Have had some time behind the wheel of the VT V6, Vt to me feels very sharp and responsive it feels faster, But getting into real times it slower to 60kp/h by around .4 second, Pretty good still, Just slower again to 80, Then slower to 100 but getting closer, I feel they zip around town very easy to drive.

Truth is with a Cam and ECU you can drop over 1 second in time easy, Do it right and you wont loose power down low, I was just reading up on a VN V6 that has a custom Cam and ecu, It ran 8.6 0-100 16.3 1/4 stock, After Cam and ECU 7 flat 0-100 and 15.11 1/4.
It was done right redline was keepd at factory level so the car still had big power down low but increased in the mid range and top end very well.
There 6's can be worked on the cheap better then people know. Those times from a VN would match a VS 185i Clubsport and a VT 195i Clubsport, that's pretty respectable.
Another thing that cut .5sec off its time and added more power in some gears and rpm was a 3.45 diff up from the 3.08.
2 things that can make a large change to your car.

Now with the ecotec it will be better power wise but weight again.

Somehow I think your costs would be somewhat more than $2k to get it running in a car.

WOW.... very impressive there! I have a VP 5.0 that is into the 5's with no more than cold air and extractors/exhaust and a tune. Haven't even touched the motor yet!

Didn't the OP just ask about a vp v6 and vt v6? Why all the malarky about dropping a v8 into it? I would love to drive around in a f1 car but you will notice I didn't mention that to the OP.

In relation to the question asked my feeling is that no matter what you do to the vt, it is was not made to be responsive in the same way as the previous models. One of my mates worked for holden back then and told me ( not sure if it true ) that they were trying to get rid of the wheel spin from Mums on the way to the shopping mall, pulling out into traffic, from the vr vs. I remember driving those things thinking how crazy they were when doing a right turn and nailing it. With others in the car thinking you are constantly lighting it up on purpose.

I would think the only way to do get the same throttle response/feeling would be from a tune. I've got the l67 and to me doesn't feel responsive as the old vr and vs still.

well i wasnt wanting to spend anything near the cost of a V8 into it, so no. few small mods sound like the go, CAI and tune. i think the exhausts in the VT's seem to have a pretty decent design as stock (maybe change the last muffler to something a bit smaller.
Also might need to look at getting some weight out of the car....somehow. looking at the VT's it does look like the body is a whole whack bigger and mine is a Calais so theres bits of extra weight everywhere.

Error codes....well as i had with my old VT (must be a common problem) my ABS module must be stuffed again. the traction cntrl and ABS warning lights come on. This happened with my old VT and holden charged me $800 for a new module, this car i have now already had a spare module in the boot so he musta been planning on fixing it. Now that iv learnt a bit about the commy's i wouldnt let holden charge me $800 again. But...if i change it over myself does holden need to reset the computer or anything?

The small sttock air intakes on VT's, are these no good as CAI cos i thort they were made to get cold air in.

Its intersting how holden made the cars a little less responsive. Maybe they should have kept them kicking and then had a few granny series commodores which could of had a soft smoother tune.

i think that line should really only apply to american engines. european engines are tiny and get some impressive power

thats not even close to what my standard 165kw 5L would do its not v8 snow its getting the best value for money, i personnaly wouldnt do anything to a v6 liek exhaust, retune, CAI, K &N filter, different plugs bored throttle body etc... although K &N and plugs are a consumable so need new ones of them so they are ok but all the rest would cost thousands for minimal improvment i would just keep it stock if you want fast get a v8.(CAI about $300 exhaust $1500 dyno tune $1200 bored throttle body etc etc it adds up shift kit auto..)

reaper maybe so but you would have the old stuff to sell and get a bit back. or you buy a written off vx with an ls1 for 4-5k then get everything u need and some more stuff to sell pluss the old box and motor you would probably end up breaking even so its free but not everyone can do there own work.

I was thinking that myself i have enquired..

As men we love the cubic inches

But in cars nothing beats forced induction

GreenFoam has a VN on tune in the 6's
Swaps positions with you under cover.

Honestly no BS at all, I did the timing of a VX SS stock to 60kp/h,
3.15sec. Then did my old VP to 60, 3.35sec that's pretty impressive, Then the beast is awoken and it's gone!!!

It's always hard when you have a V6 to start with.
I bought a repairable right off Berlina V6, To me this car was mint and worth the buy low km's a 2000 model i jumped at it, The other car i went to get that day was an VTII 99 Executive with Gen3 perfect sleeper. But jaws had attacked the front and it looked bad, Also it was $1,000 more expensive and had around 20,000 more km's, So i went the luxo rather then power.
I still regret it but i still think i made the better option with my head and not my heart, So now i'm stuck with the V6, But at least i got all the eclectics to play with and a very fresh motor and trans interia is mint well looked after car which is good.

But for around 2k, I'd get some good number from the motor. About 200kw, Around local driving it would be a beast and very hard to budge off the mark for anyone, That wouldn't show in the 1/4's times but with still having great econemy and driveability I'd be pretty happy with that.

I had a VT acclaim v6.. all bolt ons etc.. but wasnt all that inspiring, performance wise, to me. So off it went, and replaced with a VS v6.

with the same power plant the VS just feels more nimble from point to point.

VT wins hands down for interior comfort though! love those seats
