3.6 vs 3.8 0-100kph times

[henry-k]

Hey guys,

I'm interested in hearing your 0-100 times in the 3.8 ecotec or 3.6 alloytec in vy and vz's respectively.
I am looking at buying a manual ute in one of these models but I'm undecided as yet. I hear the vy is quicker off the line due to more low end torque? Not sure how this affects things in the long run though?

Cheers,

Henry

3.8 have more mods and is prob a bit cheaper to mod as well. IMO 3.8 sounds better and will do roughly same 0-100 times.

IMO the Ecotec is a nicer engine to drive. Also seems to be cheaper and easier to work on and modify.

Iv had both alloytec and Ecotec with mods and I have to say I think I'd still go the alloytec again over the ecotec, yes the ecotec sounds better but my alloytec is defenetlly quicker with similar mods that my ecotec had, I'd go the 190 high output alloytec tho in manual or 5 speed auto over the 175 alloytec in the 4 speed as it's much better to drive, pick up etc

With 0-100 I did film my alloytec one night and it done it under 6 seconds, would be 5. Somthing seconds but it's after 100 that I notice how much better it keeps pulling over what my old 3.8 ecotec did.

Hopefully this video works but u can see 0-100 in my alloytec



It's not standard so I can't really comment on both standard engines but I guess if your after the quicker one you won't be leaving it standard anyway.

Thanks for your replies and scott - nice dash looks so much better than stock

I have had a couple of ecotecs , and currenty have a VZ SV6 , and with out a doubt the VZ is a more pwerful engine , more so than the VS L67 I had and more so than my modded VX V6 , the Alloytec revs harder , and I think sounds better as well , the ecotec is a bit asthatic sounding .

In my personal experience the alloytec is better when taking off from zero at the lights. With the alloytec I generally only need about 2,000 revs to get off the line and up to speed (and beat a lot of other traffic in the process) whereas I needed to use about 2,500 revs with the ecotec to do the same thing.

Surprisingly the ecotec seemed to perform better when overtaking (going from 100 to overtake a car on the highway) and seemed to give me a better initial burst of speed than doing the same thing in an alloytec. Don't know whether anyone has an explanation for this.

I've had both and I prefer the ecotec (just to add to the confusion)

Mainly because the exhaust I had on mine sounded heaps better but also because you can find parts/mods in a heartbeat.

Got 280k out of a very poorly maintained 3.8 so I can't really fault it. (hadn't had oil changed in 50k when I got it and still ran for 3 years without missing a beat til I sold it)

Hay mate yer the mods I had done to my alloytec was-



- CPR6 manifold
- OTR air intake
- full twin exhaust with stainless hi flow cats and headers
- LSD diff with 3.46 gears
- dyno tuned

It went really well for a N/A v6, pulled a 14.2 down the 1/4 mile, and was quicker than the supercharged ecotec with a 10psi pulley, also was quicker than the standard vx ls1
