from buick to ecotec

[VSCristian]

i've repeatedly read that the buick is torquier than the ecotec, and the VN-VRs are quicker than the VS, is this true?

if so, why would holden make it's newer car slower and less torquey?

i drive a VSII ecotec, and while very happy with it, was just wondering.

i know that overall torque and power are higher in the ecotec, but does the buick out do it and if so why?

i'd be interested to know that too, ive heard the ecotecs are more fuel efficent anyone with an eco tec want to tell me how many kms they get out of a tank?

i like the buick engines but the ecotecs are enticing me too.

Use the search button, it's been covered heaps. Every Ecotec vs. Buick thread just ends up with people saying that they "think" or "feel" that one is better than the other. Every answer is completely subjective as there is no control to compare against.

To paraphrase though, the Ecotec delivered (off the top of my head) a 5% cut in fuel usage and a 13% or 17% (I can't really remember) increase in power over the Buick, that's why Holden used them.

There will be no definitive answer to this though, racing a stock VR and stock VS of this age against each other will prove nothing (well to me anyway), every engine has been treated differently.

My personal preference is the Ecotec simply because they have more bolt-on bits and pieces, and the apparent improvements over the Buick. Speed off the line on a stock engine isn't really a concern for me.

i get around 10-12l/100km around town and 8-10l/100km on highway (110-120km/h)
that's with the aircon off.. with it on it eats an extra 1-3L/100kms!!!

VSII, enclosed pod CAI, extractors, 2.5inch catback

lol I have a stage 2 cluster (not for much longer! :clap so i'm not up with those measurements, how many kilomeres per 63 litres (assuming vs/vr tanks are the same size)

lol i must waste so much petrol i have my air con on ALL THE TIME haha.

i was wondering because i was looking at manifold spacers for the ecotec and the ad said "make it have the low end punch of the buick"... now either the buick has more low end or the manifold spacer's not a good thing

 

[VSCristian]

it says 59 in the book for the VS... anyway i get around 500-600 around town without aircon...

and 400-450 with!!!!

 

[nathanVY]

a bit better than me. max ive gotten thus far is 490km highway driving. 300 around town thrashin it a bit. around 400~ mixed town/highway driving (non thrashed lol)

If you took a VS that had been well maintained (serviced regulary etc) and a VP that had not been looked after, of course one is going to have more torque than another.

Heaps of people here will tell you how well their VP / VS etc runs, but it's all a much of a muchness.

The most accurate way to finding out would have been to take a brand new VP and a brand new VS off the showroom floor in complete stock form and running them down at a track or something. But i highly doubt that would be possible nowadays.
